JD 2305 Uneven Bucket cylinders

[justman777]

All, need some help here as I'm not the best with hydraulics. I've noticed for a while now my bucket cylinders (the ones that move the bucket) appear to actuate the bucket unevenly. I took the bucket off today, and sure enough, the left cylinder (from the drivers seat) actuates a tad slower than the right cylinder, which results in an uneven bucket. I measured the cylinders at one point, and the left was about one inch shorter than the right. Both cylinders appear to be on the same hydraulic lines, which "should" make them at the same pressure....and thus actuate evenly. But it doesn't. The right cylinder is noticeably and visibly faster than the left cylinder.

Any ideas? Is there something in the slow (left) cylinder that could impede the flow on both extend and retract? The FEL lift cylinders are on separate lines and aren't affected.

Thanks!

Just a slightly longer circuit. I have this issue on my JD 6200 and it's a major PITA to attach tools. I'd like to think there was a good reason why they didn't tie the two sides together with a torque tube!

Yep. It's not that much of an issue for me attaching something since it's off by just a bit, but it does seem odd they'd design a system that required the quick attach arms to be in the same relative position to accept an implement, and then not design the hydraulics to compensate. Where it does impact me is the ability of the bucket to be level when digging. I always dig lower on the right side because of it. :thumbdown:

I see no way unless the bucket is BENT how bucket cylinder rod extension can be different with cylinders attached to bucket. Yes with cylinders disconnected on rod end then cylinder with least resistance will move 1st or the most. The timing rod on attachment quick disconnect is designed to keep cylinder rod extension equal unless timing rod is LOOSE.

IMHO bucket digging lower on one side is caused either by bent loader boom or rear tire of tractor has lower air pressure on lower digging side not by bucket cylinder rod extension length.

With the bucket off the cylinders can move uneven without a timing bar. (that's why they have some sort of timing bar)
With the bucket on it can't do that unless the bucket is twisted, which is doubtful. You have a different issue. (low tire, unlevel loader arms, Etc.)
