Troops, Took the sort-of-new-to-me tractor for a spin around the back 11 yesterday which is all standing on edge, some of it pretty seriously. About halfway through my traipse, the low fuel idiot light came on and the fuel gage started acting posessed, reading from 3/4 to 1/4 with stops in...

How difficult/expensive is it to replace a seal in the front axle of a 3720? Does it require a bunch of special tools, shims, what? I found a nice little puddle of oil on the floor under the right front wheel of my new-to-me 2009, 3720. Any advise would be appreciated...

I currently have a JD 3720 (cab with R4's) mostly dedicated to a front mount snowblower. This summer I would like to set it up for mowing about 5 acres of a grass commercial lot (no trees and not lawn quality grass). Would most of you guys recommend a Deere midmount mower (I found a like new...

My questions are: 1. My tractor is 58" wide with R4 tires, will the 60" broom get close to covering the tractor width when angled? 2. I have lots of sidewalks that go right up to buildings. How close can you actually sweep next to a building? 3. My sidewalks are only 3' wide with gravel...

After ignoring the A/C for two+ years due to reliability and high pressure switch cut out issues, I decided to fix this once and for all! Any of you guys who use your tractors in hot dusty conditions....know the AC is mediocre at best. It’s a bad design (undersized condenser, battery blocks...

Left side seems to be leaking at the pivot joint. Right side at the lower seal. I read somewhere that heavy use of front end loader could cause axle leakage. That痴 why one has a front loader, correct? To carry heavy stuff. Anywho is there any permanent fix? I hate duplication of effort. Thanks...

I have JD3720 on my trailer right now and was wondering where to hook the front chain to. I understand crossing the chains and using binders etc. In times past I have already just put a chain around the front axle and tie down to the respective side rail, but that pulled out on the front...

I thought the point of an SCV was if multiple spools were activated simultaneously the valve balances the pressure between all 3 spools???? When I run my Clemens weeder with the 3rd SCV spool on my Deere 3720 I can't get the 1st SCV spool to raise the weeder (normally for raising the FEL) but...

I recently purchased a 2009 John Deere 3720 with 600 hours on it. It has always had a FEL and a backhoe on it so I don't think the PTO was ever used. I tried the PTO but it does not engage. I have 12 volts to the PTO solenoid with the PTO switch engaged and the resistance through the PTO...

I have a 2009 John Deere 3720 which seems to run just fine. Has plenty of power and not a lot of smoke. It has a little over 600 hours on it. Recently while I was examining the tubocharger, I noticed that the waste gate seems to be stuck in place. I can work on it to free it up, but I got to...

If you don't mind I like to run even relatively minor tractor repair jobs past others that may have had some experience, unless I've done it before, and in this case I have not. Replacing the leaking hydraulic hose seems like a straightforward deal. The leak hasn't busted out but it is...

I have a JD3720, awesome little tractor, does what it says on the box, but now I want to do a bit more.... I want to upgrade the hydraulics so that I can fit a trencher onto it, does anyone out there know if this is possible? Or is it going to have to be a PTO drive HPU unit?

I Have had a 3 series tractor for about 10 years now, first a 3320 and later trading up to a 3720. I really like the 3720 but lately have really been thinking about getting into a bigger frame. I do a lot of hillside mowing and use a PTO wood chipper so the extra HP could be useful. Would also...

All of the sudden I can't seem to get our 3720 to crank. We have plugged the block heater in for several hours (overnight) and temps are in the low 20's now but when I turn the switch, nothing happens. The glow plug indicator comes on and stays on along with the warning light (! light). You...

I have a 2008 JD 3720 and have been getting the Error Code 57 for a couple of months now. It is random and doesn't seem to effect the operation of the tractor, at least until this week. Yesterday I tried to start when it was really cold. Plugged the heater in for a couple of hours and let the...

I just get one issue fixed and I run into another. I have a John Deere 3720 and just put my mid mount mower deck on. When I raise it up it immediately starts to lower on its own.

Looked at a John deere 3720 cab today Drove by a John deere dealer today. Stopped to look at a 3720 cab with a 375 backhoe that was out front. It seems so small and compact compared to my Grand L 3240, it had 75 hrs on it. I looked at a 3320 before I bought my Kubota didn't notice the size...

I'm using my tractor with a shear and grapple to clear red cedar. It's going fine but I'm very concerned about the viability of a hydraulic line to the steering ram. It hangs quite low and I'm concerned it could hang up and snap the fitting. I'm unfamiliar with the fittings. Is there...

Hello - does anyone have the TM for the Deere 3720? I need to adjust my TPS and was looking for some advice before I purchase the service manual. Phil

The relief valve on the low side of the compressor leaks. Anyone know where I can find this part? It has M10 x 1.5 pitch threads. Deere says they can replace the compressor for $700.00 or aftermarket for $450.00 but why do I need a new compressor for just a little ten dollar part?

Here is my new 3720 just after delivery. It has eHydro, air seat, wide R4s, 300CX with skid steer carrier, 5' rotary cutter, 72" quick attach drive over belly mower, 72" heavy bucket, 3rd function hydraulics, and the EA root grapple. I've only had about an hour to play with it so it still...

I bought a used john deere 3720 - no owners manual. I don't want to sound too stupid but how do you know when the pto is at 540 rpm? I just bought a king kutter 72" inch rototiller and it is suppose to be run at pto of 540 rpm. Thanks for your knowledge

I bought a 2005 JD 3720 - I have a compost pile of leaves about 12 feet high + wide and with the bucket on I am unable to lift the leaves from the ground - am I expecting too much of it. This is my first tractor with a bucket which I bought since I grow giant pumpkins weighing over 1300 pounds...

I'm trying to remove the starter on my JD 3720 because I'm thinking the solenoid is defective. I have all the wires disconnected from it as well as the two bolts removed that appear to hold it. Only thing is, the starter will not even begin to budge, and it appears to be still solidly attached...

With some time in the saddle, I'm wishing the tractor had load match but at the time I ordered the tractor I was ignorant to the utility it would provide. Reviewing the JD website is a waste of time because there's more outdated information than current. One link says it's standard on e-Hydro...

Im getting the 3720, I prefer it for my needs over the 4x20 series for now! I think the Yanmar is a better engine from what friends that have a 3720 say over the Deere 4cyl in the 4x20's. I am getting the 300cx loader. What bucket is standard? What bucket should I get? HD bucket any better...

I have 2 conditions I would like feed back on. When I start the tractor for the first time on a chilly day it starts at a high idle (approx 1100) with the throttle lever all the way down. It will stay this way for about thirty seconds and then go all the way down to normal. Second, when this...

Anyone know the procedure/process for removing the ignition switch on a 2005 John Deere 3720? I've taken the nut off of the front of it, but there does not appear to be enough space behind it to push it in to remove it from the panel. Thanks, Ken

Hello all. I am trying to decide between a new 3720 or a clean used 4720 that a local dealer just got in. I have about 8 acres of rolling meadow that I want to hay. I will also need machine for general property maintance. I need a loader and backhoe on the machine. Does the 3720 have enough...

Ok, I have been reading the forums quietly for a few months now and finally find myself needing to make a decision. First of all, let me just say that I grew up running older JD tractors (B, 70, 830, 7520, 4020, 4430, and 6030) and recently bought a 40 ac parcel that I plan to turn into a small...

Does anyone know if the 6.8 gallons listed to fill the hydraulics, transmission and rear end also includes the front axle? I filled all 4 of those (took 7 gallons) but the rear end dipstick in still on add. Have you filled your rear tires (R4 15 X19.5)with windshield washer fluid - the john...

Was hoping someone out there knows if there is a front mount snowblower available other than the 59" that John deere sells. I was just quoted a rediculous price from a dealer yesterday and am looking for alternatives. I need a kit that will lift it as well. Thank you for your help!

Ordered a new 3720 cab today. 385 backhoe, 300cx loader, front blade, snow blower. Trading in the 2520. Dealer is giving abot 14.6% off list

Well, the big trade went through and I think the 3720 is going to fit my needs much better than the 4320. Today I tested everything out and I think we're good to go. I really like the R3 turfs and think they'll be me much better on the lawn next year when I get the auto-connect 72" deck. For...

I want to change the fuel filters on my JD 3720 and the owner manual says to change the filter only when the tank is low. What is the deal with that? Will the tank drain out? What do I have to watch out for besides fuel all over? Thanks for any tips. Chuck

Have a JD3720, 1 yr, 120hrs, e-hydro trans. Suddenly one day (pushing brush in a pile) it would only move at about 10% speed that it should. Had to jack the throttle way up to nurse it back to the barn. Called the dealer and let it sit for 2 days until they could take it. When they loaded it...

Howdy Did some maintenance on the tractor this weekend (oil,filter, front axle transmission fluid change).....and went to grease the front axle fittings.....and they're covered/sealed. The manual shows them as open (where they can easily be got at with a grease gun).....so I attempted to pop...

I have a John Deere 3720 with AC. When I use the machine, the AC works for about 30 minutes and then starts to fade(blow warmer). Any ideas what this problem might be? I've cleaned the AC filter and checked to make sure the compressor spins freely. Does it sound like the system just needs to...

I seem to be having a compressor that stops after about 5-7 seconds.......and figured I would start with line pressures (as these things kick off if there is a pressure irregularity). I just bought and received the technical manual and parts catalog.....and no pressures stated (just "do not...

Hi Guys just wondering if cab vibration at about 2300-2500 RPM with a 3720 is normal? I just don't remember hearing as much vibration sounds like it might be coming from the cieling or maybe just the hood vibrating behind the dash. Not sure yet but seems like more then I ever noticed before. I...

Anyone using a M and M Hydra Snip on a JD 3720? The website doesn't specify the pressure/flowrate.

I needed to move some dirt and gravel the other day and noticed my hydraulics were noiser than normal. The outside temperature was in the 40's so it was cold. I let her warm up for 10 minutes and the engine temp was normal. When I raised the FEL the hydrualics were noisy almost a winning...

Yep, that's it. I've gone through the search but haven't found my situation so I'm looking for advice. I have a 3.5 car garage at my home and no place at my ranch to store anything covered. Therefore, everything needs to fit in the garage. My intention is to have my wife's CTS behind the...

Anyone have a recommendation on MX5 vs. MX6? The JD website recommends an MX5 for a 3720 but it also shows the MX6 is well within the capacity of a 3720. I'll be mowing some woody shrubs under the 2" guidance but mostly cutting grass on trails I'll drive with my truck. It's three passes on a...

I just ordered the quick attachment for the 3 point hitch for the 3720. How does it work and do I need to change the pins on my implements to work with it? I can't tell from this picture I found but it looks like the pins are different to match the quick attach>? does the quick attach come with...

Just wondering if all the squeaky noise in the cab with every little bump I hit is normal in the 3000 cab series? I got the steering wheel squeak sorted out with a washer but the cab itself really makes lots of squeaky sounds on every little bump I hit. Kind of annoying on a machine that cost so...

I am buying a new JD3720 cab for my property maintenance company. I already have a kubota 7510 that has served me well. The new machine will be for rough cutting for a development company and some *not too much snow removal in the winter. The Canadian dollar is high now and JD is offering 60...

Guys, I was looking to buy a New Holland Boomer 3045 w/cab, but the CVT on the tractor has got me worried. If I spend the money, I would like to keep the tractor for at least twenty years if possible. Now I am looking at a JD 3720 instead. I know the JD 3720 tractor is smaller than the...

Thinking of adding a chipper/shredder to my gear. Wallenstein BXM42 suggests a minimum 35-40 HP for maximum function. I think my JD 3720 should handle this alright. Just curious if anyone has this setup and what their experience has been.

Maybe one of you can shed a little light on my 3720. I get an audible knucking sound when idling, wheels turned to right or left, Idling so I can hear easier. Wheels straight, it seems fine.I tap the hydro pedal to go forward or reverse, and let off the pedal I hear a sound that comes from the...

Well after much debate over needing/wanting more tractor than my 2720, but not wanting the extra 1k# rolling across my yard.... The poor yard lost the debate. Overall turned out to be about 12% below msrp and a very fair trade (showed me more for trade than what they're advertising it for)...

Hi everyone. My wife was running a box blade in our field the other day. She stopped the tractor to answer her phone, and when she went to go back to work, the tractor would only go about 1/2 the normal speed for the RPM's she was running at. She immediately parked the tractor. I checked it out...

I made a tough decision. Here's the story. Back in January 2008 I bought a new 4720 with the factory ComfortGuard cab. It's a tremendous tractor and from December until the April it is the ideal tractor for me. Plowing snow and hauling firewood is a real joy with this tractor. However. I have...

are the jd3720 any good looking at buying one can anyone help please .. thanks

I ordered the 6" extenders for my cabbed 3720. I would like to add the JD rear fenders but not sure how they fit and how they are attached. Anyone know? They look like they are about 2" black plactic, Might help with the wheels going out 6".

HI I have a 3720 with a cab & FEL, got lots of suggestions for stability on another thread - thanks I looked at the front wheels and the JD manual. It looks like I can flip them side to side and get a wider front wheel foot print. Has anyone done this? Since I have the R4 tires flipping...

I am looking at both K 4240 normally aspirated and JD 3720 turbo. I live at 9000 ft above sea level. Not much air up here, but dealer saying non-turbo not a problem. I need some real life advice. Anyone know how performance on Kubota will be affected?

Ok here's the deal... I ordered a 3320, with the same options added below, wether the 3320 or the 3720, in mid December and after a month of no show tractor I (and the wife;)) changed our minds and ordered a 3720 with factory cab, 3rd SCV, 300 CX loader, R4 treads, front mount 59" snowblower...

The stock equipment sidelink limiter on the jd 3720 was a plate in a tube, with several holes drilled. It seemed that there was never a pair of holes that lined up quite well enough to keep the boxblade from slopping back and forth a few inches (quick hitch installed too). I initially modified...

Situation: JD 3720, FEL, Rimguard in R4 15-19.5 tires. Moderate success with snow removal last year. Mix of blacktop, dirt and gravel drive, 900' long and hilly. Just purchased tirechains.com 2 link chains w/o V-bars. Will these fit without putting the tires in the wide mode without...

A few years ago I built a snowblower for a JD 4100. You may remember the thread I wrote as I built it: http://www.tractorbynet.com/forums/build-yourself/17523-snowblower-plans.html Since then, it has been adapted to a JD 2520, by getting the correct brackets for the quick hitch to mount to the...

Can I install a PTO mid mount kit on my JD3720.

All summer I found myself jumping on and off the tractor a lot doing farm cleanup stuff, and quite often I would hop back on at the right side of the tractor. That's a big step up after a few hours of this activity. I looked under the platform and found that the same features exist on the...

I'm still new to tractor ownership, and even though this is a dumb question, I have to ask. I have a JD3720 with IMatch Quickhitch attached to a Frontier RC2060 cutter. When the tractor sits level in my garage, after disconnecting the PTO shaft from the tractor and lowering the 3PH all the way...

Hi folks, I'm a new tractor owner (JD 3720/300CX FEL/Frontier RC2060 cutter) and have been curious about one thing in particular. Does anyone know the maximum slope allowed before the JD3720 will roll over? I see TractorByNet sells a tiltmeter, but without knowing the critical angle that the...

My JD4720 came with eThrottle. Is eThrottle also available on the JD3720? Thank you, Regards. FRIZ [I]兎Throttle is standard on the 4720 with an eHydro transmission. At the turn of a switch the transmission operates just like a car by electronically linking the engine and transmission together.納/I]

I would welcome and appreciate input on the value of the following tractor: 2007 JD 3720 with 400 hours, loaded Cab with all available accessories New, once used 60" 7 iron Mid Mount Mower Deck Removeable front end loader with bucket Dealer acquired this unit in connection with a trade-in and...

I hate to be dumb but I got off my tractor and the engine cut off and now it will not crank. I am getting an "encutof" on the display. Did i hit something, a switch or etc.?

Some of you guys must think that I am crazy. I just bought a John Deere 4720 and now I am talking about buying another tractor. And the Kubota B3030HSDCC cab and John Deere 3720 cab have not only different price points but are also different in size. For this (serious) discussion let us consider...

My Auto connect mower deck will not stay level. I level the deck, make a couple of rounds mowing and the deck is unlevel about 3/4 inch. Leveling yokes are not moving...appears to be flex in the linkage. My JD Dealership, as well as the engineers at the factory cannot figure it out. I am...

Calling all JD 3720 owners: I bought 78 acres of land. The land is in the NW Indiana, mostly flat a few slight elevations. Most of it is wooded, approximately 10 acres are meadow. Three ponds: 1.5 acre, 1+ acre and 0.5 acre, all with trees and grass around them. The house has also trees and...

Which backhoe choices are good for the JD 3720? The on-line lit seems to suggest the 375, but also lists some other numbers. Any experience here? If the 375 is the only real choice, I see they have a rockshaft assist mounting system, to two fixed plates. How does this work (good, bad...

I have a question about checking the transmission oil on my 3720. Should the bucket and the 3PH be at there lowest positions? ie on the ground? I am having a bear of a time getting the oil level right with this tractor. As you can surmise, it is my first big tractor. I checked the oil...

A local dealer has a used JD 3720 open station tractor for sale (2006, 463 hrs., one owner - like new condition, e-hydro transmission, larger R4 tires, 300 cx loader and JD 448 backhoe). What's a fair price for this set up? I know the 448 backhoe is also used on the 4x20 series. Are the 3x20...

I have a John Deere 3720 (44HP eyhdro) and absolutely love it. I have a wallenstein 6" Hydraulic chipper, landpride rake and JD forks. Since we always need "more" implements I am planning to add a backhoe this Spring. I have been researching different models and have a few questions for those...

Greetings Gentlemen, I live on a horse farm in Colorado with a 2400 ft driveway and have to plow very large amounts of snow - sometimes even 6' drifts! Anyway, as a female, I am pretty worried about getting the right blower and one that I can handle myself. My 3720 is an open model, 4x4...

My dealer gave me a sweet deal on my non cab 3720 trade in. I took the plunge... I have a day to change anything if needed.... Did I miss anything? 3720 Delux cab with air ride seat (rear wiper and worklights Mid PTO Dual SCv and Rear SCV Large R-4's AutoCruise, Motion match, & other BS Horn...

Thanks guys/ I finally decided to order a new jd 3720 cab tractor. This machine is awesome. Powerful.Sleek. I could go on and on.....However the biggest decision I have to make before ordering is the tire kind. Should I get the r4's or r3 turfs? I will use this machine for everything...

I just purchased a JD3720 44hp compact tractor and a Rhino 172 6' rotary cutter. This is my first tractor and I am concerned that the mower is too big. Does anyone know how I can determine if this is safe? Thank you!

I accidentally went green for a couple of years...though I have come to my senses and now own a Kubota again.

I have been off the forum for a while due to coaching high school football. I finally decided on the JD 3720 hydro with the 300CX loader with a 6 1/2 Curtis skid steer snow plow. Got the heavy duty bucket. For mowing I bought the Woods PRD7200. I also bought a Split Fire wood splitter for...

I live on a 150 acre farm and have a NH TN75, a JD5325, JDCT332, Kubota L4630, and a Kubota BX2200. My grandfather, who lives on part of the farm is planning on getting a tractor which he will use for mowing about 10-15 acres. He can't get a John Deere 4720 because the machine is too large for...

First, I'd like to say that both my wife and I think this is a great forum and we respect the fact so many of you can take the time to provide opinions and feedback to even the novices (which a lot of us are!) We are about to take the plunge and buy our first tractor, so we are quickly trying to...

I am bringing my discussion here for information from those on "the other side of the fence". I really appreciate the knowledge that is aquired from these boards and the general TBN site. Here is my dilemma: I have purchased 9 acres of land that I will be building a house and shed in the next...

My 3720 is approaching 50 hrs so I checked the owner's manual to see what service needs to be performed. SURPRISE!! Nothing specified until 200 hrs or one year whichever comes first. All of my previous tractors (six) specified service at 50 hrs, eg, engine oil & filter, transmission oil &...

I am trying to decide which size tractor would be better for 9 acres of pasture that I have to mow. I get a lot of tall reed canary grass on the land (if it's not mowed regularly) and that grass can grow up 6 feet tall and 1/2 inch thick. IMO, anything less than 35 PTO hp and a 5ft bush hog...

I'm looking at these two tractors and would like to get your opinions about them. I've been looking at 40hp class tractors and decided on these 44's because of the stronger loaders they can handle. I have 13 acres that will eventually be a working pecan grove, but I'll need to disk and drap...

I just bought a new JD 3720 and the mechanic didn't recommend going to synthetic for the engine oil. Something about the emission sensors and such. Is he giving me a line or should I listen. I ran Amsoil in my NH and it worked great. Thanks Bob

I've found a good jd dealer and a great Kioti dealer (wallace PA) in my area. I'm looking at the cab version of both machines with a FEL, 9" auger and 60" rotary. The DK45s is 5k lower than the JD 3720. I've gotten feedback that the JD is better because it had better pumps and a hydro trans...

I just purchased a small farm in New Jersey. The property is just under 20 acres and is roughly 10 acres of pasture. The pastures are massively overgrown and need a lot of work. My intention is to convert this to horses. I was thinking that I need a wide cut mower, mid PTO preferable, a...

Great forum, I wish I had discovered it much sooner. I just ordered a JD 3720 with air ride seat, larger R4 tires and 72" 7-Iron MMM. The dealer gave me a 12.5% discount off MSRP and refused to budge any further. He did agree to sell me the deluxe grill brush guard at his cost (supposedly...

Just took delivery of new JD 3720 Cab and new 7 Iron 72'' mid-mount mower. According to mower Operator's Manual, the front upstop clearance is to be set to 1/8 inch in raised position by adjusting the two rear yokes. I've adjusted the yokes to where there is only about 1/2 inch of threads...

Looking at purchasing a new 3720 Cab tractor with attachments. I would like to make sure the new tractor has all the latest product improvements. It seems that one of the best ways to ensure this is with serial number. Does anyone know the beginning serial number for the 2007 3720 Cab...

Any comments appreciated.

Any comments appreciated.

We are in the research phase of our first tractor purchase and would like to get some opinions about the difference in these two models: The 3720 is a 44 hp eHydro 35.0 PTO, 4WD, 101 ft-lb torque, weighing 2900 lbs. The 4320 is a 48 hp eHydro 40 PTO, 4 WD, 127 ft-lb torque, weighing 3700 lbs...

I have been researching for some time for a first time tractor purchase. Own 37 acres in TN; about 20-22ac open fields. My research has led me to either the JD 3720 or 4120. I am not sure which model would be best. I thought the 4120 was the choice but wonder if that might too big or heavy for...

Not sure if anyone will remember the old canvas heat housers we use to install for winter use on farm tractors. But i recently got a JD 3720 w/FEL and would like to add a heat houser for it. thanks bob

Haven't had much time to use it. Got the tractor, 300x FEL with 4n1 bucket (not a JD) and the MX5 bush cutter. Will try to take some time this weekend to give it a work out - especially the bucket. Want to get good at grabbing things with the 4n1. Got lots of piles of cut trees/shrubs that...

I`m looking to upgrade from a 4310 w/loader to a 3720 w/300cx loader.What can I hope for on trade in value of this unit against a new 3720? My 4310 has 500 hours and is in spotless condition.4310 is E hydro and has never given any problems.Thanks

Dealer just gave me his final quote and I'm about to pull the trigger on a new JD 3720 with Cab, MFWD, E-Hydro Trans, JD 300CX Loader with 73" Bucket, JD 48" Pallet Forks, and a Rhino Bush Hog 295 Rotary Cutter for $31,000.00. Am I in the right ball park or should I consider a different...

This thing rocks!!:D

Fellow Posters, I took vacation last week and on the way home picked up my new 3720 tractor. Immediately, I felt like it fit me "like a glove." I purchased the 2060 box blade and the 300cx loader, and got the third SCV and air ride seat/cruise for comfort. Since I recently bought a 757 ZTR I...

What should I pay for a new JD 3720 well equipped, just the tractor? Options needed are: Cab, air ride seat, rear hydraulics, rear lights, radio/CD/weather band radio and eHydro transmission. Thanks in advance for your help!

Im comparing between the JD model, i know all of its specs, how is the new holland model? Whats its price for the 47hp motor model listed here plus a loader? any pros/cons vs the JD priced at $22,xxx without a loader?

I went to my dealer's shop yesterday and got to see and touch my new 3720! They are modifying it this week and I expect to take delivery by Friday. In the shop the tractor looks HUGE.....way bigger than the 2210 I am trading. Took a deep breath, gulped and climbed aboard. The new body style...

I am very impressed... I can't believe how quiet it is inside of the cab with the engine at full blast... I kept thinking my throttle was working it's way back down.. but it wasn't.. it is just a very quiet space... I could even talk normally on a cell phone while working in it today... I will...

I took delivery of a new 3720 this weekend. Have not really had a chance to test it out yet. I took it to my business from the dealer and hooked up my new FarmPro chipper which I had ordered a couple of weeks ago. I will be taking it out to my new homesite which I will be building on in the next...

After what seemed to be a long time, it has finally arrived. The tractor, tiller, and belly mower came in a few weeks ago but had to wait on the loader. Last Saturday, I went to my local dealer to pickup my new toy. Since our place of business is less than a block away, I drove it to it's new...

Anyone been on both of these machines and can compare. We have a 10-acre place where we will be tilling an arena, moving dirt, manure spreading, cutting alfalfa, maybe baling, backhoe, loader, lifting 700# bales of hay - maybe 1tons. I'm not sure the 990 will work but open to all feedback...

I have been in the market looking for a 3720 with Factory Cab. This is what I wanted for a complete package. 3720 with Cab, 300cx Loader w/73" HD Bucket, Bolt On Edge. Larger R4 Tires, Filled with Calcium. Deluxe Cab package offers Mid Pto, 3 Rear Remotes, and Air Ride Seat. One quote from...

I'm taking delivery soon of my new 3720 and would like to find a good root rake to go with it. Where would be a good place to start looking for one that fits the JD quick attach that's standard? I guess a better question would be.... is there a specific root rake to fit the 3720?

I would like to know what the road speed of the 3720 goes for in MPH. The UK site says 33KMH. That comes to a speed of 20.5 MPH. Is this a typo? or do you 3720 owners know if that really is the correct speed. It seems quite a bit faster than previous models. I am seriously thinking about...

So for a few months now I have been settled on the JD 3720 with a FEL and backhoe (300cx/448), and just went to buy it from a dealer ... who also handles NH ... and had a TC33DA with FEL on the lot ... I had only considered the Kubota Grand L's as a competitor but liked the JD better ... so...

Anyone done some research on comparing these models.

Looking for info on the comparable JD product to the NH TC40. Are the JD3720 & ND TC40 comparable in performance and uses? Is there another JD model that is comparable. Know about the 4000 series tractors, but looks like they are in a heavier weight class. Ideas, thoughts. I see in many...

Trying to get comparison of models for consideration. Posted in the NH & JD sections looking for ideas on the comparison of these two models. Know the least about the Massey comparable model. Can anyone tell me what would be a close match in the Massey line of tractors?

Are these two units comparable? Very familiar with the "get on it and try it" and the "which dealer do you like" considerations, which is good advice. But my question is from a side by side comparison in performance. Anyone with experience using one or both? Are the target markets for these...

Have been looking for over a year now for a CUT. I'm building a house and will have plenty of work for it. I have been through all the colors and I think Green is the winner. I used to have a 2355 JD. Bought it new. Best **** tractor I ever had. It was like loosing a member of the family the day...

Fellow Posters, I have been working my new 3720 hard this week, doing a lot of box blade work, etc. This new machine impresses me greatly with its power and generally mean attitude. My tractor also has the 300 cx loader, which does really well. Due to the loader and the extra power over my...
