john deere 2640

Have 18.4 x 30's on Dad's 2640 right now, but tires are showing small cracks on sidewalls, and are likely from 1980's era, so would like to replace, with decent used, if I can find some. Inner axle bolt pattern is 8 bolts, on 9.5" diameter 'hub', outer wheel edge has 9 bolt pattern, on approx...

Anyone else have a JD 2640 and know where the starter relay is actually located? I have the tech manual, but the one pic it has for this is grainy and has an arrow pointing to (upper corner under the right cowl) what I've confirmed is actually the voltage regulator (which is square -- the relay...

Dad gave me our 2640 that I used to work on as a kid. He mentioned it needed a valve replaced in the injector pump. He's most likely going off of what one of their mechanics told him. Said it would take tearing the tractor down just to get to it. I'm not so sure. The main symptom, I...

Hi, I've never owned a flail mower before, and I want one to keep my CRP grass in check. My JD 2640 has about 70hp at the PTO, and I'd like to go as wide as possible, within reason. I'm considering a 96" Woodmaxx, but don't know anything about the brand, or if a 1400 lb attachment is too much...

Hi Guys, recently inherited my Dad's JD 2640. Have been having to jump start it; suspected very poor batteries (has 2), but now am not so sure. Topped off water in each cell of both batteries (almost 1 cup in each cell!), and they seemed to respond very well to recharging (bank reads now 13.6v...

I cannot lift the bucket or three point and the power steering is no longer working. The fluid levels are OK and the hydraulic/transmission filter is clean. Is this an issue with the pump at the front of the tractor? Is there any way to diagnose this? Thanks.

My Tractor A John Deere 2640 was left to sit for several months. When I tried to start it, it would crank but did not Fire at all. Wondering what the issue may be and wonder if it has a fuel shut off valve. To stop the Engine there is a lever that is pulled to stop Engine. Would imagine...

I was snowblowing the driveway when all the lights on the tractor got real dim and the alternator light came on. After I shut off the tractor it wouldn't restart. I brought the batteries in and they tested as bad batteries. After I replaced them it still wouldn't start. I put a screwdriver...

My block heater does not appear to be working. Had it plugged in for two hours and could not feel any heat when touched the engine block. I checked the resistance with multimeter and was close to 0 (0.2 ohms). Given this is supposed to be a 1,000 watt heater it looks like it is shot. before I...

Brake Appear To Be On or Engaged on 1980 JD 2640 stick shift. I checked hydra fluid ok. Front wheels are free when I roll up the front end/fork. Occurs forward and backwards but not all the time usually cold. Any answers or experience resolving issue. Thanks.

I was disking our arena with our 1980 JD 2640A when I noticed it was loosing power. I barely made it out of the arena when it died on me. It will start up fine and run for about 20 seconds and die. My first thought is fuel filter but if that does not work, but filter is clear and no air bubbles...

hello I have a JD 2640 (1979) with what appears to be a 1,000 rpm 21 spline pto spindle. I recently purchased a King Kutter rotary mower with a six spline 540 rpm shaft. I have been told that some JD tractors have the capability to run both 540 and 1000 rpm, you just unbolt one spindle and...

What would be a fair price for a John Deere 2640 with a 146 front loader 1978 new paint job? Everything seems to work except the left brake and the key does not activate the starter every time, you have to turn the key several times for the starter to engage.

I need to remove my front loader so I can work on my tractor. I can not start tractor, so I have no hydrulics. How do i remove the loader?

I found a nice looking JD 2640 on Craigslist with the following description: I have not seen the tractor in person, but talked with the seller today. He explained that the engine is not new, but was rebuilt because of a noise made by the counter balance shaft. While they were in the engine...

It looks like in order to change the fan belt the manual says that you need to remove the main hydraulic pump drive? Is this the coupling located at the bottom just below the radiator fan? Looks like two bolts? Thanks

My father in law is thinking about buying a JD 2640. He found it on Craigslist, so he isnt sure on the hours right now, but the photos seem good. It has new tires and battery. Does anyone know of any problems with tractors. I know that statement is kind of vague, but just looking for some...

I was looking at a John Deere 2640 tractor which has had some extensive work done on it. I had agreed to a price and the dealer delivered the tractor. No money has changed hands. I was looking at the tractor in morew detail and could not find the tractor dta plate on the frame. I did find...

I have a couple hydraulic leaks on my JD 2640 that I am trying to diagnose. The first one leaks near the steering column and down onto the brake pedals. The second leak comes down between two metal lines just below the hydraulic pump, but I can't see the source of that leak. Any help in...

Been lookin at a pretty straight JD 2640 with about 4,000 hrs. I would like to use the tractor as a baler machine and pull a MoCo. A small square baler and maybe at some time down the road a round baler. At 70hp pto - it would seem to have enough power to get the job done. What else should...

Hi Everyone, I am a new member & first time post. Today I was trying to shift from low to park to unhook my bush hog when my shift stick pulled completely out of the socket. The tractor is now locked in low gearing, also 4 rings attached to the rod came out with it which two apeared to be...

For the 3rd time in less than 2 months, one of the two O rings (actually flat rubber washers) that seals the fluid in between the Housing and the valve cover is shredded. After the second event I carefully smoothed the surfaces and took care to evenly tighten the 3 holding bolts, but it's...
