Just the other day I removed my blades off my ZD1211 (I agree stupid overly complex design) to sharpen & balance. When I reinstalled them the right side blade screw would spin the shaft while trying to torque to 80 lbft & I’ve had them of many times with no issues. I removed it and checked...

If it’s a diesel Absolutely!!! 90cummins

Snow blowing backwards with my compact tractor is challenging me and the F series kubota with heated cab would be perfect but the price for new a new one is out of the question. I found a 2006 Jacobsen turfcat 628d 4wd with heated cab, snowblower & mower for $4500. Supposedly has only 1900...

I added a turbo to my 1720 Ford SSS years ago because I love the tractor just wanted more hp. I never had a dyno but I had 60” snowblower that required frequent use of the clutch to avoid stalling. After the turbo installation there was no more bogging down the improvement was huge and that was...

My wife helped me sort the SBS batteries recording rest voltage & specific gravity which were 40 degrees. I picked the best 12 out of 30 batteries. I decided to use 1/4 by 1-3/4 copper buss bar for my connections because I have it on hand. Had to buy a 23/32 drill bit for a close fit on the...

Thanks for the file I'm starting to make sense of AH's again!!! 90cummins

I agree!! I have 4/0 copper cable & lugs to make up connections but I need to look at the terminals more closely there may be a slight taper. Can't take chances and improvise with the current these can produce. If anyone out there in generator land would like some of these I would be happy to...

Yes M10 threads

Here the are not sure how many I’ll keep. They just have posts. According to code on top they were made in 2009.

Hope to pick them up this week, unfortunately there are no buss connectors for the batteries. I have heavy copper buss bars which I can make temporary connections with but I’d like to find the proper connectors, with the current these batteries can supply improvising long term may not be in my...

Still over my head but it’s starting to compute. 👍90cummins

Help needed comparing battery capacity. I’m planning to replace my Trojan L16’s with industrial SBS STT2V420 two volt batteries. The SBS batteries have the following AH ratings. 8 hr rating of 475 AH’s. 48 hr rating of 596 AH’s. 120 hr rating of 661 AH’s. 240 hr rating of 686 AH’s...

I went over & we discussed pricing today & he asked me what they are worth. I told him you’ve always treated me right give me a price, he threw it back at me & after some thought I offered $20 apiece. He said that’s exactly what he was thinking. So for $240 I can replace my 4 L16RE’s. I...

Don’t know mfg date they were wrapped up but they looked extremely clean & the few we checked were at or above the full charge voltage. We have a pumped storage facility in town called Bear Swamp which my nephew works at & they use them for backup power for pumps & support equipment. They...

My local recycler called me yesterday to tell me he took in over (100) SBS STT2V420 industrial storage batteries. Tested a couple which were 2 plus volts. Thinking of buying a pallet of 30 if he’s reasonable. These would be a huge improvement in capacity over my original L16’s purchased in...

Turbos increase HP at any given engine speed by increasing torque. That’s why turbo engines are generally smaller in displacement. Forcing more air in the cylinders means more fuel can be injected which creates higher combustion pressures which = more torque. 90cummins

I changed the front tire size (turf tire) on my 1720 Ford after the fronts failed due to dry rot. From day one I noticed the front tires pulling harder than the rears when in 4wd. The fronts were too tall resulting in the front tires always kicking snow/dirt towards the rear. When using 4wd I...

Patrick good info in that link. I’ve encountered issues in the past with unbalanced inverter & generator loading in the past. Looks like I’ve got some reading to do, always something to learn here. Thanks 90cummins

I have 3 phase 120/208 in my shop which is separate from my house.

Patrick said So the inverter can provide a "grid" for the solar city AC system to synchronise to, no charge controller needed. The other one I was thinking is that you could feed the input of the inverter using your small honda with an autotransformer to give you 120/240. My little Honda is...

What’s red to green mean??

I’ve considered buying the solar charge unit from Schneider electric but cost is a but high. With the efficiency of my system & the fuel I have available I can’t justify the cost. My nephew works for the power company & they have very large 1.2 volt wet cell batteries that they replace...

The inverter is from Schneider Electric Xantrex XW4024 24 volt input 120/240 volt output pure sine 4000 watt. It has a Gen assist feature where it will assist a small ac generator if the programmed load is exceeded. Very useful for those with small generators. 90cummins

I didn’t expect these results! After what seems like an eternity I’ve finally programed the Conext AGS (automatic generator start) so it’s operational. Without exaggeration I have spent hundreds of hours looking for information to understand this poorly documented system. Before I go any...

I have a Ford 1720 thats always parked inside after snow blowing & to open up floor space I put the loader up & set it down on a support. I went in the garage next day & found loader still up & the 2x4 on the floor. As the captive oil in the hydraulics warmed up it expanded & lifted the loader...

Staying Green Side Up!! Getting to be a chore. 90cummins

Yes it was me 90cummins. Pittsfield Massachusetts had PCB super fund site that was remediated years ago and they required 24/7 air monitoring. Honda EU2000i generators were used for years with only 1 unit having issues. It started burning oil (hours unknown) and needed to be re-ringed. I bought...

I not sure. I think it is a DC string with dc output up to 400+ volts. I’ll dig up the literature. 90cummins

Try purple power at Walmart. $7.00 gallon and works excellent. I have heated it up in a container used it to clean internal engine parts. 90cummins

Patrick I’ve considered that for quite some time. There is a charge controller made for my system but I’ve hesitated because my system output is monitored remotely. There could be serious issues if (I hijacked it)!! On the other hand if SHTF & the grid was down indefinitely I would definitely...

LI batteries lot of capacity and life cycles with a small foot but expensive. My nephew works for the local pumped storage utility with many huge lead acid batteries to operate pumps for cooling & lubricant pumps to allow the turbines to spin down without damage should power go down. Waiting...

Thanks👍 Appreciate that! Having worked around them you can appreciate how difficult it can be getting a program to execute commands properly. My installation would have been much easier if the company supported their products with more detailed information. I would not recommend this product...

The generators were on the floor at first but they shook the building & the harmonics were unbelievably loud. I resolved that by placing a radial tire under each generator. That solved all the vibes & noises. The exahust pipe adds some heat but not enough to be an issue. The cold air intakes...

My most recent wet stack victim was a Chinese quiet gen with the Yanmar L100 clone. It was on a summer job site running weeks just powering an occasional skill saw & keeping batteries charged for cordless tools. It ran flawlessly for weeks then started spitting & sputtering then quit. When I...

Rustyiron I have not started a thread on my system. It is not connected to my solar or the grid. It is a standalone system. As you mentioned it can be very efficient. The Yanmar will run 4 hours per gallon supporting the entire house minus the electric dryer. If I was to run it on auto it...

I use rotella T6 5w40 full synthetic in all my diesels. It definitely makes a difference in cranking speed which diesels need to start. Don’t know the specifics you’d need to look it up. 90cummins

This is my powerhouse. These are my diesel backup generators. Both are 28v DC generators that support my 4kw battery backup. During an outage I can use inverter power or my Honda EU2000i portable if I have to do a cold black start. I have other backup sources if needed. My second source would...

After months of on again & off again trouble shooting and talking with a few very smart controls people I’ve finally managed to understand my Xantrex AGS (automatic Gen Start) which now functions properly. My primary gen is an L100 Yanmar that belt drives a 28 V 450 amp Niehoff alternator. I’ve...

I have a similar style snowblower on my tractor and being **** about details I adjusted the chain as I would on any piece of equipment. I had no issues with mine (chain) until I decided to give it a good pm which included adjusting the chain per standard practice. During the first storm the...

I was in my barn making room for 4 bins of firewood (each bin is approx .4 cord) that will eventually be used for heat if it’s a cold winter. In the process I found a Generac 4000XL that I prepped and stored 10 years. Seeing this I thought I should bring it into my shop & check it out. I made...

No benefits in this gearbox application for synthetics. I’d use the cheaper 80-90 or 90 weight. 90cummins

I made rear forks for my tractor for moving pallets & carrying my log splitter. Not a believer in using tractor hydraulics to operate splitter due to low flow rates and the fact the tractor can’t be used while splitting. I made my splitter so I can easily back into it to pick up & move without...

Bring your old thermostat to your local parts store & try to match it up with one that’s close enough that you could modify size wise to fit. I did that with my Ford 1720 & installed a 190 degree thermostat. I had to reduce the OD a bit for it to fit. It’s been in there for 10+ years no issues...

Absolutely!!! That’s the worst thing you could to any diesel. Lookup wet stacking. Diesels that are idling or operating at a very low power levels for prolonged times do not make enough heat for proper combustion allowing moisture to form and the rings and cylinder to glaze amongst other...

In response to how often should a PTO gen be operated to maintain residual magnetism I don’t know. Mine has set several years between uses with no problems. I have never had an issue with portables either. My nephew’s standby gen had to be flashed a couple years ago after running flawlessly...

I have the same unit. Bought it prior to Y2K from Generac. Funny story as to why I’m bought it and all my other generators. When Y2K was being hyped up my wife said if I can’t curl my hair I’m not going to work! My reply was ohhh you’re going to work. That’s how it all started. True story...

I have a Cleanburn CB2800 waste oil furnace in my 40x60 garage that’s saved me thousands of dollars. Free heat. My bil just gave me 55 gallons yesterday at todays price of $5.599 that’s $305.00 saved. 90cummins

When I bought my zd1211 I took the zero % financing with kubota insurance. Sales guy said it would cover anything including stupidity. This could qualify?) 90cummins

I agree very nice machine. I bought my zd1211 2 years ago & have 160 hours on it. The only problem I had was a coolant leak that was hard to find. Ended up being the lower radiator hose. The controls are tight (no slop) for precise control. I mow 4 acres & no regrets!! 90cummins

Holly molly that's some bad settling, is the building sitting in a swamp? It was like that 30 years ago when we purchased it. Area is not wetlands so I have no idea why. After we removed all the old concrete we could see no reason for the concrete to heave. The fill was clean sand nothing...

Thanks for that info M59. The floor was replaced because the original was cracked & not level side to side. There was a 5 inch elevation difference across the width of the doors. We ordered a new 17’ door which required the floor to be level. This is only used for parking in the winter so I’m...

Could you recommend any particular product? Thanks 90cummins

I just removed the old concrete floor and apron in the house garage and I’m putting in a new floor approx 6” thick. I would like to coat/treat the new concrete to protect it from road salts & freezing & thawing. What would you suggest? I’ve looked on line at many products but would like some...

What failed on the engine? Is there a common failure mode? My BIL brought up a Generac 22+- kw engine for me to check out. It blew oil all over the interior of the cabinet but was still running. Would like me to check it out & rebuild as a spare if feasible. I recall reading somewhere that...

Can’t beat the utility & efficiency of the small inverter generators. I can run the essentials during the winter with my EU 2000i. 90cummins

I’ve had a 275 gallon diesel tank for years to fuel my tractor. My shoulders are extremely weak from injuries and handling 5 gallon containers of gasoline was difficult. I had a Scag STHM that I really liked but sold it because of refueling difficulties and the overall beating I took riding...

I finally found the coolant leak. The leak finally left a telltale sign that I could see with the mower up on a lift after a couple days. The radiator hose above the oil filter had buildup on it that could only be seen from below. Relieved to know where it was going. 90cummins

Thank you I’ll give that a try. 90cummins

I could probably find one but this one was rated for over 100 psi and had the set pint I wanted. 90cummins

I have no idea what a pull-up resistor is. The #12 run input is only looking for the run signal which is 12v. Time to stop trying to think eyes are crossing🙄 90cummins

Yes it will. Thats why I think I need a relay and possibly a time delay for this to work. Time delay will bypass grounded pressure switch allowing engine to start & run while oil pressure builds up then put the pressure switch back into the circuit (oil psi contacts open) allowing engine to...

Sorry guys the full image didn’t transfer

I’m needing some help here. I’m back in the powerhouse to configure the low oil pressure switch for the Yanmar. The switch is normally closed with no pressure and opens at 30+ psi. I have a time delay relay I think will do the job but I can’t wrap my head around it. 2 photos are attached one...

Those photos of a professional control panel certainly give me an example to follow. I feel an upgrade my be in my future. I have solar city so I can’t hijack any power. However the thought crossed my mind if things got crazy. I would need a charge controller rated at 600 volts to do that...

Patrick you are out of my league! Beautiful work!! I’ll look at the finger trunking that would work nicely. The batteries are located in my house garage & generators are in a separate building that’s about 1 foot from the house. Conduit goes thru the walls for the heavy cables that connect...

I agree with everything you are saying. Haven’t gotten to the fans yet which only cool the generators. The batteries are in a different room than the generators and is not heated. I still need to work on getting the oil pressure switch and hour meter integrated into the system as a safety...

After reading your response it makes sense to disable both the float & absorb settings because the inverter charger will go thru the bulk, absorb & float process when the utility power is restored. This forum is a huge knowledge resource! Thank you. 90cummins

I just finished transferring the control wiring to a larger board so I could tidy it up. First time I’ve built anything like this any suggestions? 90cummins

I have a couple questions regarding the setup of the controls for the my DC generator when in auto mode. It is set to turn on at 24.5 volts & off at 28 volts which is subject to change. The run time is also undecided perhaps 1 hour minimum to allow the engine to warm up fully. The question I...

I've no experience with using grease in gearboxes but high temp grease would have a tendency to channel meaning that if you packed a gearbox full of high temp grease once the gears turn they would push aside excess grease that is in the way and create a open channel to run through.. The...

I have always used ear protection but I now use ear plugs in addition to my ear muffs when I'm mowing with my Kubota ZD 1211. The drone from the mower deck is annoying.. I find no difference between regular ear muffs or shooting ear muffs with Bluetooth. 90cummins

Last year when I was struggling to get the AGS to work I thought I smoked the first AGS module and that that was why it wouldn’t work so I bought a replacement. Now that my system is working properly I though I would install the original to see if it was actually damaged and it worked fine👍👍...

Grease with moly is preferred for bushings on loader. 90cummins

Ralph in Va Before I created my system I researched all the gens out there and concluded that the Isuzu was in my opinion the best of the best. 90cummins

(your pictures show a 24 volt relay). You are right I missed that. I have 12 & 24v relays on hand and picked up a 24v relay to show the schematic, both 12&24 v relays are wired the same. Sorry for the confusion 🙄 90cummins I’ll add the pressure switch when I get some time. Thank you 👍👍

I will try this when I get a chance thank you!!

The fuel solenoid is 12v so I needed to use a 12v relay for the run signal. You are correct the controls do not know if the engine is running that is something we need to pursue fortunately the Yanmar starts like a first gen Cummins 1 turn & it’s running when it’s warm out. The oil pressure...

Feeling like I won the lottery!! So I thought it would be a good idea to see it would operate properly in the auto mode. I programmed it to start at 25.5 volts and shutdown at 28 volts. I plugged in a 1500 watt heater & watched the voltage drop to 25.5 volts & 30 seconds later it started &...

Note; red wire was not used. 90cummins

While waiting for a revised wiring schematic I wired in a 12v relay using the oil pressure switch in the circuit, it was not happy kept showing a fault. So just experimenting I connected the relay as follows black #86 to ground White #85 to fuel Yellow #87 to run sense #12 Blue #30 to fuel I...

The oil pressure switch I have has 2 terminals one is for a pressure gauge and the other is a switch to ground that opens at 30 psi so it looks like I need to use a relay to make this work???? 90cummins

The oil pressure switch opens at 30psi. I purchased an hour meter but it is not yet installed. Last night I purchased a 0 to 60 second timer for time tuning the crank time if necessary. I also have more 12 & 24 volt relays if needed. I think I see some light at the end of the tunnel 👍 90cummins

I’ve tried type 14 which did not work. I reconfigured to type 7 and found that it works as it should if I put 28 volts to the gen sensing line #12 shortly after the engine starts to crank. The engine stays running and the alternator energizes after the 88 second time. The delay was installed for...

Check for tight connections. Loose connections cause heat like you are experiencing. 90cummins

For test purposes When in auto I set the trigger to start at 24.5 volts and stop volts at 28 or 1 hour max run time. In auto it would start the run sequence but immediately shut down. Too hot outside to work so I’ll do some troubleshooting in the powerhouse. 90cummins

Great I may take you up on your offer!! 90cummins

To protect the AGS I have installed 28v relays protected by 5 amp fuses to handle the fuel, crank and pre-heat if used.

Patrick you are correct the Yanmar needs a run (fuel) wire and (start) crank wire. It starts then shuts down. It has an oil pressure switch that is not yet wired into the system. I will dig into it again on Monday. Thanks for the input!! 90cummins

Some of the other version are pulse start requiring a momentary start/stop push button. I will do a video when I get a chance and post on utube showing what I have & demonstrate what is going on. Thanks for taking an interest! 90cummins

My primary generator is a Yanmar which needs two wires to operate. Fuel & crank. I’m using version 7 without connecting the preheat on the Yanmar. The MEP-952b has preheat so to simplify I’m using 7 for (if & when I automate that one) 90cummins

https://www.amazon.com/Schneider-Electric-Conext-Automatic-Generator/dp/B095B4LYT7 Let’s try this link.

My gen type is 7 or 8 currently using type 7 but with no pre-heat.

I can’t even post a clear photo🧐

I can not copy & paste the link🙄 so Here is a photo of the AGS OEM package for link. Appreciate the help this is very frustrating!! 90cummins

I’m not sure!! That is what I’ve been trying to understand. The manual provides very basic wiring schematics but fails to explain in detail how & where the run signal is obtained. I have searched the web for information but found nothing that is helpful. Support is terrible taking countless...

I believe it’s software because it works fine manually but I can’t say for sure. When a manual start is initiated the fuel is turned on then the engine cranks & starts then it shuts down. I’ve installed LEDs so I can observe the timing sequence and it appears it is not acknowledging that the...

We are talking about two different things. Most injection pumps as mentioned automatically add additional fuel for starting. And (2) manually moving the throttle to add fuel to start. I’ve owned a first gen Dodge diesel since 1990 bought new & still have it. The first gens from 1989 to 1993...

I’ve never heard of a (rule) that diesels need full throttle to start. Some diesels such as the p-pumped dodge Cummins need some throttle to start but not full. My 1990 dodge starts at idle position except in very cold temps which requires some throttle. I have some small diesels, Yanmar...

It may be (possible) to restart with considerable cranking but I would become familiar with the bleeding process to avoid starter damage. 90cummins

I’ve repaired a couple of the mil-surplus L70’s that had issues similar to yours. The problem was caused by wet stacking then a long period of setting unused. The moisture in the oil corroded the injection pump cam lobe which in turn affects the injection event. remove the injection pump &...

It depends how many kw’s you need. If it was during the day when there was a large load I would run at 2200 rpm. If you needed minimal power let’s say thru the night i would use the slower engine speed to conserve fuel. I wish my tractor had multiple PTO speeds. 90cummins

Yes.

If by some chance you received a load of (bad diesel) you will wish you had an overkill filter system like mine. I had an issue with fuel once, don’t know how or why but I said it would never happen again thus overkill!! 90cummins

I hear you. But tire size & pressure can have a huge impact on drive line stresses and failures. Engineers have what is called a 4 square gear tester where 4 gears are installed on 2 shafts and preloaded with a jack screw that pre-loads the gear faces. Large gear sets can be tested with...

Wastegates are used for various reasons. 1 it prevents over boost to protect the engine and/or turbo. excessive boost can over speed the turbo causing major damage to engine. 2 it’s part of the emissions package. 3 it allows a smaller turbo to be installed which allows the engine to build...

I did a fuel consumption test on My new 60” ZD1211 which just turned 100 hours. I recorded 0.93 gph over 4 hours mowing my lawn at 1.5 inches which was over due for a mowing. The engine was working hard & bogging down at times. Diesel is definitely more fuel efficient with less fuel...

I had a Kohler CV22s on my Scag 60” STHM it had over 3000 hours when I replaced it. The valves were burned but the cylinders looked good for the hours. You should have no problems. 90cummins

I’ve been keeping an eye on my coolant level and verified IT IS NOT using coolat. After several runs recording the hot & cold high and low levels in the coolant recovery tank the level repeatedly fluctuates between the high & low marks I put on the tank. 90cummins

Not an issue raising & lowering the deck frequently. I raise & lower mine dozens of times each mowing. I agree that the raise & lower functions are very fast. All you need to do is quickly tap the up or down to raise or lower but it is nice when you hit something. 90cummins

Amsoil is certainly a top tier oil. Using it in a Kohler or any other air cooled engine provides excellent protection during extreme hot & cold operation. Oil doesn’t darken because it’s cleaning it darkens because it’s breaking down due to heat and accumulating and reacting with combustion...

Mowing season ended before I could get a handle on it. I’m documenting the level before & after each mowing (mowed once so far) so it’s too early to tell what’s going on here. I will post when I get done data. 90cummins

My most used (home made) 3pt attachment are rear forks which are indispensable to me. They are on the tractor 90% of the time in the summer. I use pallets to store my attachments on which makes it easy to move & store. I use them to lift logs so I can cut it for fire wood and also move 1/2 cord...

I’m working on a 2120 HSS and the transmission dipstick has machine marks in it from contact with a shaft/gear. The dipstick is not bent do I’m asking if this is an occasional issue or a sign of impending disaster. Transmission operates fine. Thanks 90cummins

You are correct about the (recommended) max of 250 degrees. In testing we operated with an inlet oil temperature of 260 degrees with sump temperatures approaching 300 degrees so engineering heated assemblies to 300 degrees and cooled to -300 degrees. Housings were aluminum and this ensured there...

NO! Do not fill! Stone or file the gouge flat so it doesn’t damage the cylinder. the gouge will have no effect on the seal sealing. My concern would be the filler JB WELD or what every you use may flake off & damage the new seal. As was mentioned it’s the cylinder surface that’s important for...

2 weeks ago I filled a 12 by 72 heavy wall steel pipe with concrete which will be used as a lawn roller. It is open on 1 end and filled with 8 bags of redimix. I used approximately 7 gallons of water in the mix. When will it be safe to put outside in single digit temperatures and not worry...

I made up a set of chains for the 13.6-16 turfs on my tractor using (used) cross links from semi truck tires. They will not stay on the tire because they are too short (15 inches) I need to add at least 4 inches to them so they go over the tread and further down the sidewall. New chains are...

I need advice on selecting a soft start module for my 1/4hp wood furnace fan motor. During a power outage I use a Honda EU 2000i to power essential circuits including my wood furnace but when the fan cycles on it pushes the little Honda to the limit. Once the fan is up to speed the Honda runs...

I just rebuilt my old 16hp cast iron briggs with a 0.010 over piston, rod & valve job. And it runs fantastic. I performed a compression test after break-in and recorded 125psi hot and cold. Does anyone know the actual spec or range for this engine. Thanks 90cummins

My new 2019 ZD1211 with 50 hours on it is consistently loosing small amounts of coolant. It has done this since day one and I have documented it to ensure I'm not imagining it. Between mowing's I add 1 or 2 ounces to keep the level at the low level in the coolant reservoir. Oil level shows no...

Trying to attract the complete workshop manual not having much luck. 90cummins

As I mentioned some time ago I have an L70 Yanmar with a Factory option extra deep sump with a bypass filter. The sump holds approximately 3 quarts. This engine was designed for remote applications requiring extended run times unattended. It also has an intake grid heater for extremely cold...

I did the 50 hour service today so it would be ready to go next spring. Fortunately the mower was on my lift with the new filter ready to install. As soon as I turned it off 2~3 turns it was a flood of oil. I quickly spun the old filter off & the new on on. I still lost approximately 1/2...

I am upgrading my log splitter which I built 40 years ago. I used s tecumseh 10 hp HH100 and a Viking 22 gpm pump. It has operated flawlessly other than being slightly under powered when pushing max pressure of 2500psi which would slowly stall the engine. I rescued a 16 HP 320000 series Cast...

The Intake grid heater on the Dodge Cummins diesel would work. You may need to use an automotive size battery because of the amperage it draws but that would most certainly work. It is virtually identical to yanmars L70 but much larger 90cummins

This is the first time my 1720 has not operated properly. I have 3060 hours on it and my 3pt hitch would not raise with a load unless I briefly curled the bucket. The transmission oil is regularly changed so I doubt the oil is the issue. The ambient temperature was in the 30 degree range...

I have a cast iron Briggs&Stratton 16 hp model 325431-0135-03 I am rebuilding it with a new OEM +0.010 piston and rod for my log splitter. I completely disassembled the engine to the bare block and removed the breaker points push rod and installed a magnetron ignition. The Briggs manual does...

Just wondering if they are interchangeable. 90cummins

Thank you for the photo. I finally remembered to take a photo of my deck with the missing gauge wheel. I need to fabricate something so this $15k machine mows like one. 90cummins

Do pliers count?? 90cummins

As mentioned I found the power for auxiliary lights and I finished the installation of two LEDs in the front and one in the rear. I have not used them outside yet but they throw decent light in the garage. The charging system capacity is only 15 amps so I check the current draw which was 5...

Adding work lights to my ZD 1211. There is a circuit in the fuse box (With no fuse installed) for auxiliary lights but I can not find the pigtail. Does anyone know where it may be tucked away? Thanks 90cummins

The gator blades are very good I have used them myself however I would like to share my experience with them. I had a set on my SCAG STHM 3 wheel 61 mower. The deck is manually raised with a boat style hand winch which requires considerable time to raise if you hit something. I have struck...

I ran the ZD 1211 up on my lift so I could inspect and touch everything, well designed and heavy. As you can see the front wheels were just wide enough to run up the runway so locked the front axle just in case one of the wheels went off the edge. After giving it some love (grease) one caster...

Took delivery of a new 2020 ZD1211 with a 60 side discharge. At first I was looking for used but having never operated a zero turn let alone a Kubota zero turn I decided to look at new machines with 60 months zero interest. With Kubota's optional loan insurance that covers any and everything...

I am looking for an engineering opinion on an OEM replacement connecting rod for a 16hp cast iron Briggs & Stratton model 325431-0135 which is approximately 50 years old. I want to restore it while old stock OEM parts are available. The original rod is usable crankshaft is perfect but I want...

My recently acquired 16hp Briggs&Stratton model 325431-0135 needs a rebuild due to piston scoring from a mouse nest. This engine will be a replacement for my current HH100 tecumseh on my log splitter which runs great however parts are becoming scarce. I have a 0.010 over Briggs piston ordered...

I have an old 16hp B&S cast iron engine model 325431-0135 that I would like to use on my log splitter. I have looked for pump adapters that directly mount on PTO face with no luck. Is there an adaptor that will mount a 22 gpm pump to this beast? I would really like to keep this old iron in...

I have a wards garden tractor with a 16hp Briggs that needs some love. The engine sump is part of the tractor frame. I removed the engine from the sump and noticed there was no gasket. Is the gasket preferred or just sealant? I ordered all new gaskets & seals looking for an informed opinion...

I have a 1/4hp high efficiency motor on my hot air wood furnace and I would like to install a soft start module from Schneider electric to limit the inrush current when it is on my battery backup or my small Honda EU2000i. The motor cycles on& off frequently when the furnace temp is turned...

I知 doing a service on my friends 2120 HSS which has a couple operational issues. Occasionally while operating the transmission will go into neutral then re-engage. Transmission is full and oil and filter have been changed. It has done this for a couple years and does not act like an electrical...

These were out in the woods behind my home which we purchased 30 years ago. They were not used for my home nor the neighbor's. Any one know what they were used for? Thanks 90cummins

I live in the country and my closest neighbor is 200 feet across the main road with another also to the side of me. I have no visible neighbors behind me within 1000+ feet. Would I be able to go outside in my own back yard or would I be confined inside my home? Never thought I壇 be thinking if...

I have a 40 year old Thermo-Built wood furnace with a forced air heating enclosure connected to a SS insulated chimney. It easily heats my 5 bedroom house and the flue temperature is generally less than 200 degrees. I give it a HOT SUPPER at least once a week to keep the chimney clean. I'm no...

Looks like 1 pin secures it. Support the arm as you tap the pin out to prevent damage.

My 1720 started having intermittent issues with grinding months ago when starting in cold weather. I removed the starter & found no obvious problems but did notice some oil in the solenoid so I cleaned it to eliminate the possibility of that causing slow engagement, I did noticed 3 spots on the...

My cutting edge is worn out on my 1720 60 bucket and needs to be replaced before I damage it. Looking for a weld on with holes so I can attach a Wicked root rake. Looking for suggestions. Thanks 90cummins

Well as you can see I like pliers! I have more but ran out of table space. Yea I know I HAVE A PROBLEM 🙄 90cummins

I thought the efficiency was rather high then I realized the calculations were the DC values so I added data showing actual AC power produced at 84% efficiency and the cost. 90cummins

This is a photo of my systems SCP showing actual DC input and AC output. Average conversion efficiency is 84%. 90cummins

After recovering from thanksgiving I felt ready to finally give my MEP-952b APU a good run while measuring fuel consumption and power output as accurately as possible. Below is a photo of my Excel spread sheet. The entire house was supported in addition to a 1500 watt heater for added load...

I’ve been working on a friends newly acquired sears tractor with the big ole cast iron briggs. It was constantly stalling after operating on hot days, on cooler days it ran fine. I suspected a bad condenser and replaced it but the problem was still there, so I ordered a new Magneto which is...

I double stack my blades on my 60" Scag for a better cut and recently lost the end of one mulching Gator blade when it went over one smooth rock not a hard hit just a light touch. I place the regular blade on the bottom to protect the gator blade from impact with rocks. The broken piece bent a...
