JD855 wont start

[JD_Sheldon]

A bit of an update. I tried another battery but had no success. I did notice however, that when I turned the key to start the engine I heard a small clike about 1 second later. This came from the right hand side as you are sitting on the tractor. Could this be a solenoid? The starter has had issues in the past and I used to just tap it lightly and the engine woudl start but I thinnk on this occasion they are unrealted issues. BTW thansk for the advice so far, this is great site.


Guys, Hi I have searched the forum but can't find what I am looking for. My JD855 won't start. I have checked the battery. I turn the key and the normal lights come on but when I turn it any further nothing, not even a click (well just a litte one but I don't think it even gets to the starter). I have noticed that if I turn the lights on and try to start it the lights dim (not sure if that helps). Mine is the hydra model so no clutch but I just noticed that the forward and reverse pedals won't return to there normal postion once you depress them, its like the tension has completely gone from them. I did notice in one forum that this could good be the issue, however I don't know how to fix it, is it just spring or something? Anyway any help would be appreciated and apologies if someone has already posted a similar question. By the way its 20 degrees celcius over here so nothing to do with the cold.

I know you said you checked your battery, but I think I would have to try another known good battery just to be sure it's not the problem. That is, unless that's how you checked it in the first place? If the battery is truly ok, then I would have to look at all the wiring related to the battery, ignition switch, solenoid, and the starter to make sure there are no loose/bad/corroded connections, or frayed wires.

My JD855 won't start.

Here's what the shop manual says. It's not that helpful, but at least it is systematic:

ENGINE WILL NOT START OR STARTS HARD
Check for proper fuel and fuel quality.
Test fuel transfer pump output.
or
Bleed fuel system.
Check fuel shut-off solenoid for binding and adjust.
Test cold start aid controller.

Test engine compression.

Check and adjust valve clearance.

Improper air restriction indicator installed.
Test injection nozzles.

Check injection pump timing and check
to see if plunger is stuck. or
Remove fuel injection pump and have it tested.
Check cranking speed.
Check for proper oil viscosity.
Air heater control functioning improperly
Broken starter spring in governor assembly.
Improper cylinder head torque, gasket leaking or head warped.

When I've had similar problems with my 755, it has involved the starter solenoid, so that might be a good starting point (bad pun) if you have to plod through all the alternatives. You can be fairly sure it's either an electrical issue (more likely, I think) or a fuel issue, so sorting that out would be helpful.

That really sounds like a battery on it's last legs.
It's not just the battery cranking an engine...it has to crank fast enough to get the engine started.
As Kebo wrote...use a known good battery and give it a try.

Try cleaning the batteriy terminals and tightening them. Sounds like a "bad" ground to me. Also check the connections on the starter etc.

Another update. I removed the starter and had it tested and it was fine. I agree looks like a connection issue. Does any one have a wiring and or fuse diagram?

From the maintenance manual.

About the same as before...try jumping from a known good battery.
The lights dimming is a classic symptom of a battery going bad.
