I have a basically brand new GC2400L that I have noticed the bucket drifting down on when using. I have other loaders that I have never had this problem with. I am wondering if other GC owners experience this or if I have a problem. Even with the tractor running it will drift down. If I have a load in it, it requires frequent correction, especially the tilt.

That doesn't sound right. Mine will creep down, but only very slowly, after parking it and shutting it down. It might drop 2" overnight. Don't notice any drop while using it. Sounds like a call to the dealer might be in order.

Mine does the same thing ONLY with a heavy load in it.

Not familiar with the control valve on the GC models but is there a chance their is some slight binding of linkage that is preventing the valve from centering completely? If like my Bota BX the valve is buried and difficult to access.
A couple of simple tests to try.
1) Using the loader lift the front of the tractor off the ground. Does the loader drift allowing the front of the tractor to drop?
If no I would look at the linkage connected to the directional valve to see if it binding slightly and preventing the spool from centering properly.
If yes, 2) Swap the hoses from lift/lower and curl/dump. Now raise the loader using the curl function. Does the loader drift?
If no, this points towards a bad valve section or improper centering of the lift spool.
If yes I am stumped since leaking cylinder seals will NOT allow the cylinder to move without some external leakage path.

Mine does the same with a load-I have to keep tapping the fel bucket to curl up when driving with the load for more than a couple minutes.

maybe the loader has been on and off quite a few times.
i have noticed that sometimes i end up with quite a bit of air in the loader lines... not sure what causes it, but it might be something to do with the position of the cylinders when it gets cut loose from the machine.
it does always seem to work itself out as i use it though.:thumbsup:

Let me know how it goes-my stealership says it was normal along with the hydraulic shudder I get when using the bh sometimes.

mine will shudder when i try to use too low rpm. backhoe seems to be different than the rest of the tractor hydraulics in that it needs high rpm to run smooth.

What is this "shudder" you are talking about??
Even at high rpms, when curling up the bucket or swing the boom to the left or righ, even extending the boom-the hydraulics shake the tractor and move the cylinders like a really bad video with a low frames per second rate. I've been though the zercs, the oil level, engine rpm's-no difference. Even bled the system. Happens warm or cold-more so when it's warmed up.
I don't recall it doing this with the FEL for the most part.

Hmmm. Haven't experienced that yet. I only have 42 hrs on mine though. They say it is normal? So mine should do it too?

maybe his power beyond hose is pinched or kinked somehow behind the backhoe?
i haven't used my backhoe for a while, but i could have sworn that shudder goes away at high rpm.
not sure if this is a perpetual complaint thread or what
i only have one annoying beef, that being the quick connects for the loader which are still leaking after the third dealer 'repair'... other than that i really think this is a very good machine. i have 168 hours on it and would buy another one.
edit: i just talked to my local dealer and this seems to be a simple issue of the machine working the air out of the system after you reinstall the backhoe. come to think of it, the time i noticed the problem i had just reinstalled the backhoe after it sitting off the machine all winter.

My GC2410 TLB had bucket drift and dealer replaced one of the bucket cylinders. Problem solved. Have about 120 hrs on tractor now that happen with about 45hrs.

My bucket will uncurl slowly but only noticeably with a lot of weight in it. More noticeable with the forks on. [ more leverage ] I suspect it is the curl cylinders bypassing internally, but it isn't bad enough to do anything about. I"m also over 1000 hours of pretty hard use. The shudder in the backhoe could be a sticking relief valve. I'd talk to your dealer. Good luck.

you could always take a video of it creeping... same with cdaigle430
video would take the debate out of the debate.
