The PT422 starting surging, and application of some choke made it go away. This pointed to a carb cleaning. I took the carb off of the engine. To my surprise, there was a small hose connected to the bottom side. (See attached pix, I tried to circle the points of interest) It's connected to...

Have a potential remedy I thought of last night on the Robin Engine cold start difficulties: Just a note, I have not tried this. So proceed at your own discretion. Here is my cold start set-up along with synthetic 5W-30 oil in the engine, dino 10W-40 in the hydraulic tank. I use two magnetic...

I purchased some used wheel/tires for my garden tractor to put on in the winter. There is some cracking on the sidewalls causing some air loss. Would you guys try to slime this, or install tubes. I'm concerned that if I put in slime, I could not put in tubes at a latter date. I'm also...

Thought you guys would like to see a snowblower that I converted for use with the PT422. I took a 42” single stage snowblower and made new wings with a drift cutter to get 48” width. Used the same hydraulic motor as the PT lawn mowers since it was the right speed. (Tip speed of the auger is...

Just wanted to check to see what people are using for a hydraulic filter on the PT4XX series power tracs. I'm still using the PT hydraulic filter, but with a $50 min order, wanted to see what others are using. Post the filter make and number. thanks Duane

People like rules of thumb to help evaluate things on an apple to apple basis. A common question is the comparison of diesel versus gas engines in a tractor. The common seat of the pants perception is that a diesel engine provides more useful power in tractor work than a gas engine. I think...

After putting tire slime in a tire, can you still let air out the valve stem? Does the slime clog up the valve stem so it's difficult to add/remove air. Thanks, I picked up a nail, and was wondering whether to plug or slime it. Duane

It looks like the new PTs come with a filtered hydraulic cap on the reservoir. Good idea. My PT along with the one year and older PTs have just a vented cap. Our caps are not threaded, just a two tang half turn type. I have not seen any two tang type filtered caps, just threaded ones. Has...

Does anyone know the hydraulic motor displacement (cubic inches per revolution) or grinder blade RPM for the stump grinder for the 400 series? Looks like PT offers a stump grinder with non-sharpening, non-relaceable teeth, and then a blade with replaceable teeth. The blade alone with...

Taking a stab at how the engine compartment layout change affects the overall engine compartment heat just for fun. The following numbers are ballparks for a PT425. Typically, a gallon of gas contains about 115,000 Btu per gallon. At a rate of consumption of 2.2 gallons per hour (full load)...

Just curious to see how many of you guys that are operating the 1430 and bigger units, are using draft control. It seems like it would be a nice feature. It would seem especially useful when plowing etc in float when the tractor arms ride over the implement. How does Power Trac accomplish...

Did'nt know if everyone saw this post. Super Lube is recommended by PT on the spherical rod joints etc. Super Lube may be hard to find, but at least you can get the same stuff at Lowes or a John Deere dealer. Post: In case the the url does'nt make it, look under 'lubricants' under 'what...

One of the design changes I have been contemplating for a while is the installation of a shroud within the PT hood. A while back I calculated the heat removal capacity of the hydraulic radiator on the PT. It has more than ample capacity (in addition to the heat rejection from the metal...

Hey Charlie or Sedgewood, I was showing the brochures of the PTs to a person at work today and they asked "what is the max RPM of the diesel engine"?. Do you guys know. thanks Duane

A good friend of mine recently purchased a Yanmar 1720D. (did not receive an operating manual with it.). He was having a lot of difficulty starting the tractor at temps below 40F. I did a search of cold start threads under Yanmar and discovered the thread regarding the thermostart system. I...

I know some people that own, or are looking at purchasing a PT422 have concerns about where to purchase Robin engine parts. There is a dot com website that sells parts for a large variety of engine manufacturers (including Robin) as well as lawn and garden manufacturers. For the Robin engine...

Re-reading through the PT manual again, (cold week-end), it talks about a permissive that will not allow the PT 422 to start unless the PTO is off and the tredle centered. I took off my tunnel side plates to lube the tredle, but do not see any switches or wires that would indicate a centered...

Hi Eric Just wondering how the backhoe attachment was working out. Give us a review of it's performance to date. I think a number of us are interested. (I had to dig a small trench by hand yesterday, no fun. Got me thinking about your hoe) thanks Duane

I'm curious why manuf.'s use a fixed straight line wheel on the rear of mower decks. PT uses casters on the front which are great, but the straight line rear wheels dig into soft turf and flower beds while turning. My Toro mower deck is the same way. Why not use caster wheels on the rear as...

Well, I think I have had my first problem. I have about 8.5 hours on the meter. To set-up the problem. I was out bush hogging for about 45 minutes. I shut down the bush hog to travel to a different location. When I went to re-engage the bush hog, the engine would bog down, sounded like the...

The Robin Engine manual says to change the first oil at 20 hours. I'm used to changing it at less hours on a new engine. What did you guys do? Duane

Added a spinner knob to the web of the PT422 steering wheel last night. What a great improvement. One hand on the spinner and one on the hydraulic joystick makes working and manuvering this tractor great. Only cost $12. Will be out of touch until next Tuesday, have a great Memorial day...

Someone had asked about the ride on a Power Trac. I did a comparison today. After making a 200 ft. road through some woods with the PT small bucket, bushhog and my chainsaw; I drove my PT down the road and then my garden tractor which has the same rear tires as the four on the PT. I can...

One of the previous posts regarding the comparison of Kubota vs. Power Trac traction makes for interesting discussion. The Kubota provides power to the wheels through front and rear differentials. The Power Trac provides power to each individual wheel through a individual wheel hydraulic...

I Have been Power-Trac dreaming since I first saw MossRoads first reviews of power trac months ago. I figured the buying bug would pass with time, but is has'nt so it must be real. Here is my situation: I own 2 ½ acres of land in the state of Maine, with a 150’ paved level driveway. Approx...

I received the video and brochures from Power Trac. The model I will order eventually is one of the PT400 series. Still trying to determine what attachments to get. One question in particular is the grapple bucket. It looks like the small bucket with teeth with the additional hydraulic...
