I have a Massey E 2860 with a FLX 2815 loader. Has anyone heard of the role bucket roll cylinders bending? I have a 40 year old John Deere and have had to replace the bucket because of the pressures I put on it and I’ve never bent a cylinder. This seems unbelievable that the cylinder rod could be so soft they would bend.

Or has anyone heard of a recall on this issue?

Quite common, actually.

Watch out when back-grading with FEL bucket at full dump. Especially if you have a loader with only 1" rods.

All of my JDs were former rental tractors, and several had bent bucket cylinder rods. Mostly that was the 420 loader attachment with the skinny 25mm rods. They can be straightened if not bent too much.

Certainly true.

Problem being is cylinder rods are not really designed for compressive force when fully extended. In tension there’s no issue.

If one back drags with a bucket tilted fully down and the bucket cylinders fully extended. He is certainly asking for trouble. Especially if he catches the bucket lip on something like a small stump or a root or a rock.

Good practice to back drag with a bucket tilted fully up and using the back of the bucket to do the work for you. Or maybe just to keep the bucket tilted down slightly so the cylinders are retracted a lot more than they would be if the bucket was tilted down fully.

I know this is obvious to most long time tractor users, but I thought I would just mention the details for newer guys that might read this thread.

Sorry but it is a bit strange to post the same question twice in different threads on the same site…

Real easy to bend the cylinder rods when they are at full extension and you back drag with the lip of the bucket instead of doing it the correct way which is with the heel of the bucket, not the edge.

That holds especially true if the cutting lip encounters a hard to move object like a buried rock.

You made an expensive mistake by backdragging improperly.

They can be straightened by a competent hydraulic shop for a fee...

Has nothing to do with a recall and everything to do with you abusing your loader.

I back drag quite a bit with my machine..however it's never in virgin ground. Usualy I'm pulling the top down of a loose pile.

I have always done a fare bit of backdragging with my front end loader but never at full extension of the curl cylinders and almost always in float position of the lift cylinders. Be very careful if you are using the weight of the machine when backdragging to not overload the curl cylinders.

Just my 2 cents..
