I would like a wiring diagram for a John Deere 2020 alternator.
I found the diagram.

just started smoking from the top of the radiator, thought at first the water pump, or clogged radiator. To check the thermostat I removed thermostat and ran without it. No change. Flushed radiator, and checked to make sure fluid was moving through the water pump. Next noticed that the battery was dead also. Figured a short somewhere was affecting both the cooling system and battery. Contacted JD mechanic for advice. He thought maybe the relay was dead.(the fan to cool the radiator was not turning on.) Tried new relay with no avail. Now think it may be themperature sensor. Can these short out and do you suggest any more tests? Thanks a million.

My thought is that you may have a burned out temperature sensor on your radiator. You can find this by simply looking for a plug on the radiator that has a wire chassis connected to it. these things can burn out rather easy and it could have been effected by being hit by debris or other objects that could have caused the sensor to short out. Replace the temp sensor. Usually located near or at the bottom of the radiator. Hope this helps.

I have a brand new engine (model 4045TF150 serial PE4045T773636) and it has an overheating problem. In idle it does not overheat but, when placed into run it overheats (240Degrees) within 1 to 2 minutes. The anifreeze is full and is through out the engine. Checked the temp sensor by the exhaust and antifreeze came out. I'm here in Afganistan with the air foce and would appriceate some info on how to fix. Or could i get a number of a tech to talk to. Thank you TSgt John Jones Bagram Air Force Base

I am having a problem with gas getting into my oil. It would blow out a big cloud of blue smoke,When i checked the oil level it was about a inch and a half over the full mark.
On another forum i was told one guy had his entire throttle body replaced because of a possible electrical problem with it.
Anybody else had this problem? Thanks
I know exactly the problem. I work for a John Deere dealership and have seen this problem before. It is called short-tripping. When a machine is first started, gas does leak into the cylinder and crankcase past the rings--normal--simulates leaving the choke on too long with a carburetor engine.. As the engine temperature rises, the gas in the oil is burned off and there really isn't a problem. When you take short trips or do not let the engine run to get it up to temperature, the gas in the crankcase does not get burned off and will accumulate over time. Make sure the machine is getting up to operating temperature and this could take up to 20 minutes if the ambient air temp is low.

Replacing traction drive belt for John Deere L118. Is this a do it yourself similar to mower deck belt? No instructions in operators manual for traction belt. Are there instructions on line rather than buying service manua?

Actually this is a fairly easy looking one to replace. If you go to John Deere parts and do a search for your tractor, in the parts listing it gives a pretty clear picture of the routing and configuration of the belt as it should go on, you might want to print it out to have nearby while you are working on it. You will need to remove the mowing deck to get at it and possibly some large blocks to elevate the tractor to give yourself room to work.
Look closely at the old belt if it is still on the tractor to get an idea what is involved BEFORE you start, comparing it with the picture. You will need to loosen and move or remove the belt guards and do be careful of the nylon fan on top of your transaxle

Hi I have a John Deer L110 with Kohler command 17.5hp engine. Fault is it wont start but backfires and stalls the starter mower as though its firing against the compression - I see others have had the same problem - is it timing?
This model is known for shearing the flywheel key.

pto grinds badly and wont engage. where do i start? pull back end apart?
Posted by wadeostar on
The PTO usually has a clutch that has to be engaged so that you can select the PTO rotation setting. I had a problem like that on my tractor and all it needed was a little adjustment on the PTO clutch lever, so it could disengage the PTO gearbox properly.

How do you reset the service reminder on a John Deere LA115
Posted by trolley165 on
Open the hood and you should find a yellow push button,turn the key on,then push and hold the button in for 5 seconds or until the service reminder goes out.If yours is an early model with no push button then it will go out by it's self after 5 hours are put on the hour meter.
