Farmhand f11 Oliver 770

Orrison · Jun 21, 2018

I have the Farmhand F11 on an Oliver 770. Use it only a few times each summer. This year the tractor
started up just fine, but the loader has nothing. No whine, no lift. Oil tank about 3/4 full. Still
nothing. Upping rpm's on tractor did nothing. Cylinders do leak, but no sign of oil under tractor.
Bucket up on block, about 12 inches off ground for storage. Maybe no oil at pump? Is there an air release valve? I know little about this. Any ideas?

Does it use a pto pump? Pto engaged??

Orrison · Jun 21, 2018

Okay, here's where I begin to reveal my ignorance. The lines seem to connect to a pump at the front (bucket) end of the motor. There is a scraper attached to the pto pump and that is lifting fine.

Are you using the tractor's hydraulic system for anything?

Steve@Advance · Jun 21, 2018

The front pump operates the loader.

It probably has it's own hydraulic tank, follow the suction line (the one that does not go to the control valve), be sure there is oil in the tank.

Also look closely at the pump drive shaft. Be sure the pump is turning. Sometimes the key will wear away or fall out, the shaft may be turning but not turning the pump. Have an assistant operate the control lever while you watch the pump. Be sure it is turning under load.

Yeah, there is a separate tank from the pto system. That's the one that is 3/4 full. We put oil in it, but no difference. I will check on the shaft. Thanks!

Orrison · Jun 21, 2018

No. All I have done is start the tractor. Haven't even tried to move it with the bucket down. Now, if you mean the pto hydraulic system behind the seat, that is used by the scraper. That works fine.

Sounds like the front pump isn't turning- its rare for a loader to work fine, then the next time, nothing. If pump is getting worn, or getting low on fluid, it will usually lose function gradually. I suspect the front pump is not turning- start the engine, then go up and watch the shaft that connects it to the engine. If its turning, take the front pump off and see if the key is broken.

It kind of sounds like this is the first time you have tried to use it this year. If so, could water have gotten in the pump and froze and cracked it? Or a fitting and it is drawing air?

Just a few thoughts, I really have no experience with hydraulics.

Unless you live in FL, then ignore my post.

Okay, remember I said I was ignorant. I was looking at the power steering pump. The loader is pumped through the pto. The pto, however, was not engaged. Nor will it stay engaged. Another problem for another day. Thanks a bunch for all the help. You folks are great!

Orrison · Jun 21, 2018

You nailed it. Watch for the prize in the mail! I assumed that it did not run through the pto since the scraper did and the loader had a separate oil tank. Wrong. Thanks again for the help!

Send me an e-mail. That may just be a simple adjustment problem so it should be taken care of.
