I'm wondering what might be the cause of the bucket-tilt hydraulic cylinders on a front end loader to not shorten all the way back. There is nothing stopping them, they just won't contract back all the way.

Low on hydraulic fluid??

No ..... fluid levels are right up, forgot to mention that.

Yes, relatively new to us, picked it up last spring. I'll do that measurement the next time I'm out there, maybe a possibility. They do extend all the way out. Rams don't look bent but I'll check that as well.

I hope you didn't bend a cyl rod when you were wrangling the loader off with the skidsteer.
As Jon said also, your 66L loader has extended cyl rods that protrude down to the bucket. Does the bucket roll back to the stops on the side of the loader boom arms?

No, the bucket was off when we removed the loader and the tilt cylinders were hanging loose and not close to being in contact with anything. I wouldn't bet that this is the original bucket but it looks very much like the one I see in the online 66L loader parts diagrams & parts list. And yes, there are stops on the loader boom arms that the bucket tilts back to and stops there. The cylinders just look like they could retract a lot more than they do and we think the bucket should maybe be able to be tilted further back. We have a separate bale spear on its own frame that we fitted to the loader and we could use a bit more tilt back for that.

I see on this parts link, the bucket cylinder (which I assume is the tilt) is 63.5 mm or 25". Not sure exactly what that means, maybe pin to pin or the measurement of the stroke?

The bucket shown on this list looks very much in design like the bucket on our tractor. The bucket we have has been put to use in the past, we know that for sure.

Take the pin out of one of the cylinders and see if it retracts all the way. That will assure you nothing is stopping it or binding.

Yes, stretching the bucket might do the trick, maybe
you can pass along how to do that. Meanwhile, I
guess I should have mentioned that the cylinders do
not retract all the way even if they are
disconnected from the bucket. In my limited
experience with hydraulic cylinders, they usually
come pretty much all the way back.

With the cylinders disconnected from the bucket, do both retract the same length? If so, that's the way they are made.
If one retracts further than the other, something is wrong with the one that doesn't retract fully. If you're talking 1/2 inch or so difference, the nut may have backed off the piston.
There is always the possibility one has been repaired, something changed in the process, especially if you're not familiar with the history of the machine.
As for stroke limiters, I've never personally seen it done internally to the retract length. To the extend length, yes, it's common.

Yes, pretty much back the same distance when unhooked, maybe a wee bit different but much the same. It's not a big deal really, I was just curious not having much experience with this stuff before.

Sounds like you need some lessons in geometry. To start with the bucket cylinders have a stroke of 63.5 mm. the same as the lift cylinders. If your bale spear has boom mounting pins the same distance from the back of the spear, as the dump cylinder pins, It ain't going to roll back correctly. See my pic and notice that the boom mtg pins are extended further back from the bucket than the dump cylinder pins. As I said, everything boils down to geometry on loaders. If you decide to extend the boom pin location back, you will also need to move it up just s bit also to corespond with the radius of the pin arcs.

See my reply at bottom of this thread. The stroke on your cylinders is 63.5 mm. That is all they move, even though there is still chrome rod sticking out.
The geometry on your bale spear is not correct.

This all makes sense to me now. Actually, it is a stook loader that was fitted incorrectly, the bale fork looks good but we'll check that out, we haven't tried it yet. The guy that fit the stook loader (10 square bales) to the 66L messed it up not only geometrically, but structurally. The place he chose for his top mounting location on the stook loader ended up with the tilt cylinder rod binding with a horizonal frame rail on the stook loader. When we went to use it, we noticed it right away and didn't hook up the cylinders, we just chained the top of the stook loader back to the loader for the little bit of work we had to do with it. We didn't have tilt control that afternoon but it worked OK. Obviously, we'll have to change all that. The strange part is that he also fitted the bale fork and it was done similar to or maybe exactly the same as the original loader bucket set up. Anyways, thanks for all your help with this.
