4310 geared model won't move

[jkwbako]

My 4310 geared model with ePowrReverser doesn't see much use anymore (RE Developer, Builder-nuff said) but the last few times it seems weak and once just stopped and wouldn't move. After sitting over night it was fine for 6 or 8 hours spread over several months now stopped again and won't move. Starts and runs fine and bucket works but won't move.

Friend said to check suction side filter and screen, I decided to change all fluid and filters. When I drained the fluid it was really dark and had a pearlesant shimmery quality to it; I suspect the fluid has never been changed (so much for my guys saying they took care of it). The tractor has 1000 hours on it. Also found the suction screen cylindrical filter with a tear in the top fine fabric covering. After new filters and fluid still won't move.

I hope the pump is not shot, how can I check it - any other ideas? I am trying to avoid taking to the dealer, we have plenty of time to work on it now!

One more thing (Rookie Alert!) I see posts about an indicator light flashing codes - where is it located? I can't find mine and don't see anything about it in the manual.

So far, you've replaced your fluids (although I don't thing old hydraulic fluids would have much impact on a gear transmission tractor moving (but could result in premature wear)) which leaves electronic/electrical (the "e" in ePowr-Reverser) or mechanical. I suggest the next step is to change the air filter(s) and see if that helps (doubt it, but it's the cheapest next step).
After that, I'd guess it's time for the dealer to check it out, I'm afraid. My guess, without ever having seen this tractor, is the clutch is about done for...but you never know, it could be something electronic.

air filter won't help...if its running it would at least try to move

i don't know much about them transmissions but there must be clutch packs for the shifting???

Worst case with a fouled air filter is way down on power...unlikely, but possible. And, it's jkwbako's cheapest next step (before the dealer).

One more thing (for jkwbako). Try starting the tractor in a higher range, high gear (at a fairly low RPM...about 1000 RPM). A bad clutch might slip too much in a lower gear, but might get you moving in a higher gear. This would be a diagnostic test, not a work around.
Hanson1999...it was your last comment that sparked that thought...I hope it helps jkwbako (of course, it would mean a clutch replacement, most likely).

As I remember the e-reverser on this series is like the current one. It requires hyd pressure to ENGAGE the drive through the clutch. There is actially two clutches one forward, one back. Do both operate the same? If so, look at the control to the clutch porportional valves. Some reports of failed wiring have happened. If not I would suggest the valve isn't getting opened. Working cold, but not hot, is one symptom of a weak solenoid. It uses a pressure port off of the steering pump, not the main hyd pump. Does it steer well? If not, look for the high pressure filter and check/ clean it. If you look back through my posts there is a schematic diagram of the 4X20 which is going to be similar.

I hope you replaced the torn sump filter with a new one...

There's a clutch pack for forward and reverse - two clutch packs. Does the tractor move in reverse?

Also, does the 3pt work? (Question regarding the steering function was already asked.. does it steer OK?)

If the clutch(s) were slipping - it would be worse in C range (highest). That's why it's the best way to test for a weak clutch - use a high(er) gear - and dump the clutch. If the clutch is worn out the engine rpm's will increase and drop before stalling. Harder to detect a worn out clutch using lowest gear.

I did replace the air and fuel filters while I was at it, so no luck there. I'll try the steering and 3 point and starting in a high gear.

Keep us posted on what you find, please.

jk,
Your "shimmery" oil concerns me. You should also replace that suction screen with the hole in it. You can test the system pressure:


Attach your gauge at point "A". You should have a minimum pressure of 135 psi at idle maximum pressure of 175 psi.

You've got in backwards. A clutch will slip much easier in high gear than low gear.................
