Ford 1700 - 770 loader - float position

I'm positive I left in float

Chris,
My loader is a 768 model. I'm guessing very similar to yours. I don't see anything in the owner's manual about maintenance or troubleshooting the float function.

What I've seen doing a little looking today is that the control valves and float detent can get gunked up or rusted. Might need taken apart, cleaned up and lubed. I didn't even know it wasn't lubed by the hydraulic system.

Over the years I've sent a bunch of guys a copy of the loader manual. If you'd like it for a reference, PM me your email address or get it to me somehow. I can't attach it to a TBN message thread.

Curious how the float position is expected to act on a 770 loader.

I've noticed when using the loader that raising and lowering it is a bit scary because the float position can easily be reached and causes the bucket to jump or drop quickly if I'm not careful.

Should the float position be easy to get to or should it take some force? I've got an old Bolens garden tractor and I have to hit the lever pretty hard to "pop" it into the float position.

If this works, here is a link to the parts breakdown for that controller. You should feel a definite notch when you put it into float.

On my 768, it's not easy to accidently go to float. Not difficult, either, just takes a conscious effort.

With my last tractor (NH TZ24DA), I shoved it into float all the time, when trying to get downward pressure from the main rams. It was kind of a pain in the rear. If you're worried about dropping the bucket on your truck bed when dumping a load of dirt or something, I wouldn't worry about that. With the weight in the bucket assisting the drop, you would have to do something really dumb to force it into the float position.

Broken/weak detent spring in the valve , or stuck detent ball ? Maybe the ball got stuck/rusted in the bore when you left it parked in float ?
