4510 3PH Won\'t Lift

Tractor has 20 hours. I was out maintaining a trail to a future deer stand. When I finished , went to raise the cutter to a travel position while crossing a hayfield. When I turned around to check, I saw that the BH was completely lowered to the deck. I stopped and tried messing with the control, the rate of drop valve even the FEL which was stiil working fine. Nothing helped raise the implement.

When I got home, I checked the owners manual troubleshhoting:

3- point hitch fails to lift - Low Oil Level, had checked that and it seemed fine.
Rate of drop valve closed, checked that and it was OK.
Excessive load on hitch, 6 foot cutter hasn't been a problem yet.
Hydraulic oil too cold, Don't think so - tractor had been running at least 1/2 hour.
Hydraulic oil suction screen clogged - Only thing not checked - what's the likelihood of this being the case with only 20 hours?

I would hate to drain the system and then find out that wasn't the cause.

Anybody have any ideas? Machine has worked flawlessly to this point.

Is there any type of manual adjustment which will limit the height to which the hydraulics can raise the the hitch?

I have a 4 in 1 loader on my JD4400 and I had the same problem with my hydraulics,I could not lift the back blade,come to find out I had the lever that closes the 4 in 1 bucket pulled back too far and the hydraulics were basically over working itself by trying to close the 4 in 1 and thus not being able to lift the back blade.

Re: 4510 3PH Won\'t Lift

Do you mean in the hydraulics themselves or a mechanical limit that could be adjusted? I don't see either in the manual. I haven't had a chance to have another look, it will be Friday or saturday before I get out there. I will call the dealer tommorow and ask his advice.

That thought occured to me while I was out there Saturday. I messed with the front end loader quite a bit, but that didn't help.

If yo have power beyond valves on your tractor just make sure that they are attached correctly....

Re: 4510 3PH Won\'t Lift

No power beyond valves.

Sounds like a linkage could of become disconnected on your TPH control lever or the rate of drop/lock lever is stuck/broke in the lock(off) position. Just a thought.

My buddy and I bought identical 4200s at the same time and share a couple of implements. I have about 50 hours on mine due to mowing 5 acres, he has 15 hours on his. About 2 weeks ago he had problems with lifting the loader and box blade, also the power steering was sticking. He called the dealer who came and picked it up. Sure enough the strainer on the hydraulic system was plugged. They drained, flushed and replaced the fluid at no charge. So far so good. The dealer said he had a new tractor on the lot that did the same thing. Sounds like that could be the problem, call your dealer if its under warranty.

JMHO,

Bud

Talked with the dealer and he suggested the same thing, that a linkage might have become disconnected. I will take a look today.
