M62 Loader/Bucket Dropping When Tractor Shut off...

[Putneymountain]

We’ve got about 100 hours on the M62 and the first little problem has cropped up…

The loader has begun to drop relatively quickly when the tractor is shut off. There is a clicking sound, and the bucket dumps and the loader drops to the ground over about 20 minutes.

For the first 100 hours, the loader and bucket stayed in place for quite a while - hours at least.

Anyone have any thoughts on the cause and a possible solution?

Thanks in advance for any help.

Bucket dump could be a bad piston seal in the cylinder but not the boom cylinders. Plus a hundred hours is not much time for things to wear out and everything starting to drift doesnt really compute.

My first thought is junk in the system preventing valves from clising/sealing. But while typing that a second thought that perhaps a problem with the control linkage is preventing the spools from fully spring centering. Just guessing but that tractor probably has cable operated valves?? The latter is by far the easier to diagnose and deal with.

I saw a video were the tilt and lift hoses were switched, that will tell if cylinder or valve is the issue if same cylinder drops it is the cylinder, if it moves it may be the controller.

I think your M62 is seriously broken!
You should sell it at a major discount.
I am only about 6 hours away!

#1 You should never leave a loader up in the air!
#2 It's under warranty, call the dealer!
#3 Get the WSM (aka Service manual) and go through the testing and adjustment procedure for the loader control.

Don't park a tractor with an implement in the air. Use the boom lock if you need to leave the boom up.

Just so everyone knows – we’re not parking the tractor with the loader up.

But we do leave it a few feet of the ground when we shovel material out of the bucket, and having it drop over about 15 minutes is a bit of a problem.

Thanks for the suggestions – it is under warranty – but I wanted your thoughts before calling the dealer.

I've wondered about this with my BX 3point.. it drops while running and I have to keep an eye on it when using FEL or forks if there's something attached.

The 3pt. piston ring/seal must be leaking....badly.

Forget the tractor operating police. Your loader is not working properly and needs to he fixed.

It doesn't drop quickly but if I'm running/working FEL I have to keep it in mind that it may have dropped some. I wasn't sure if it was normal for it to bleed off some as the tractor is running or not.

If the tractor has position control on the 3pt it should not bleed off while the tractor is running. Position control should actively correct for any cylinder leakage. You might want to make sure the 3pt is in position not draft control mode.

Oops- i see thats not part of the original M series post. Not sure if a BX has position control and definitely no draft control.

You don't say how far the boom drops in 20 minutes. Your machine is basically brand new...did you do the first 50 hour service? A sticky solenoid valve, bad seals, ....

Here's the circuit from the M59 WSM.

The other day, the bucket dumped from horizontal to down 45 degrees in about 20 minutes.

Yes, 50 hour service was done.

Thanks

Is the boom drifting down along with the bucket?

Please keep us updated on fix, & yes the operation police annoy me also.

Absolutely - I'm going to call the nearby dealership this week.
