john deere 820

The tractor has been sitting all winter, and now it won't turn over. The solenoid gives a loud clunk, but that is all I get. No hint of a starter problem before this. The battery is good at 12.7V at the starter. Tried shorting across the posts on the starter, and got nothing, so I'm thinking the...

the other day raking with a john deere 820 the right shifter wouldnt shift into park or II so i pulled the top of the trans off and found a 2 inch long by maybe 1/4 inch diameter tube laying in the shift fork which was keeping the shift lever from being able to shift. Does any body have any idea...

Installing the roosa master injection pump back on the driveshaft after a rebuild. Anyone know how this tool is meant to be oriented? I'm thinking the beveled side with the notch goes facing the injection pump. Has anyone used one of these? Joe

I was surprised that that the pitted line was the one with the leak (not the patched one). Is it typical to see this much foaming for a line leak?

I recently purchased a used John Deere P/N AL70191 Roll Guard and intend to install it on my tractor. Unfortunately, the fellow I purchased it from cut the attachment bolts with a cutting torch.

Hello, I bought this tractor at an auction so there is no known history except what is dismantled and missing. I don't have any experience with tractor repair and I'm stuck. I believe the tractor has not been run in over 10 years. Electrical connections everywhere were corroded. The fuel pump...

180 F or 194 F thermostat? Preventative maintenance on a 1973 JD 820. Western Oregon is a fairly temperate part of the world. I can't tell if there is much of a difference for one vs another. Any thoughts? AT22961 Remarks 180°F (82°C) AT22963 Remarks 194°F (90°C)

I was coming over a ditch and when I lifted the box blade the left rear lift arm bar threads stripped out of the bottom piece and let the box blade drop on that side. I let it down and put a chain around the bottom bar to the rock shaft connection so it would lift the box blade up so I could get...

Hi, I've got a '72 JD 820 and bought the recommended replacement switch #al19890. Does anybody have a diagram for hooking this switch up? I can't figure out which wire goes where. It didn't come with any directions. Any help would be appreciated! Thanks

Time to flush the cooling system in my JD 820 3 cyl diesel (circa 1970). It has been a few years since the last flush and with all the developments in coolant types I'm not sure what AF/Coolant to use. The operators manual just says to use ethylene/glycol 55% and 45% water. It currently is...

Hey everyone, I was able to start the 820 with a jump, but it stalled in the blackberries. It would not turn, or click, and I was unable to jump it again. The battery was showing about 0.4 volts and needs to be replaced. Could this be as simple as a dead battery? What should I replace the...

I restored by Dad's 1970 model John Deere 820 (3 Cylinder Diesel) tractor. I am 60 years old now and I drove it brand new right after they unloaded it when I was 10 years old. It was the worse for wear after my Dad passed away in 2008 but, I brought it back to life and use it every time I am at...

Hello all! Any advice about a few hydraulic leaks in a 1973 John Deere 820. There is a leak coming from the base of the steering column and another on the right side below the seat from a small metal line (presumably a hydraulic return).

My deere 820 was making oil and was run this way for a while with way too much oil. After I replaced the fuel pump and changed all the oil out, the tractor is no longer making oil, but it is smoking pretty good out the tail pipe and the blow by tube. No loss of power is noted and the smoke is...

My 73 John deere 820 has no differential brakesbut with the pedals locked together the brakes work fine. I say no differential braking because if I pump the individual pedals fast, it may actuate the brake or not. Is there a shuttle valve sticking somewhere or what?

I have a JD 820 3 cylinder diesel that is leaking fuel into the crankcase. Suspecting the fuel transfer pump, I went to replace it. The local GreenSouth store and the JD online parts site both show two pumps, neither of which match the pump on my tractor or the gasket to the crankcase. (The...

Hi all, I have a John Deere 820, serial number 065272L. I've owned it since 2005 and have used it sparingly. For several years now I've known it had a problem charging the battery. I'd put a new battery in it and it would start 5 or 6 times, and then I'd have to start jumping it; after ten or...

I found an and in the local paper for a JD 820 with Koyker loader and new tires. two questions. Does the 820 have power steering? Assuming the tractor is in good shape, is $8800 a good price (yes I plan on offering less).

Yesterday I started up my 820 (3-cyl) to charge the batteries and circulate the fluids, since I hadn't started it in about a month. After about 15-mins of running at about 1300 rpm, it just stopped running, like the switch had been turned off. It restarted right away and ran for about 20...
