Hydraulics don't hold

[Lt706]

I have tried searching for this issue and may not have the proper verbiage but here is my issue when my tractor is shut off and I have either the fel or a 3 point attachment raised eventually it will creep back down to the ground. If I have my brush hog on the back and the machine is running you can watch it raise up a little to correct when it creeps down I machine is a 2016 ck35 any advice will be appreciated.

Thanks
Tom

Really not a good practice to leave them up.I always drop mine to the ground for safety reasons.Only time mine remains up is when a deer or two are hanging from the bucket and it may drop a couple inches over-night.

I normally will not leave them up but if I shut down to run in the house with my box blade left up it will have dropped a few inches in less than an hour just doesn't seem normal

They will all creep down eventually.

The key here is TIME. How long does it take to creep down 1-foot?

 

[Lt706]

2 hours

Is this a CK35 or a CK3510? They are different tractors.

 

[Lt706]

Ck3510 sorry

Dropping 1' in two hours is probably gonna be considered acceptable by the MFG and they wouldnt do anything about it.

How many hours on machine? And did this just start doing this suddenly? or has it slowly been getting worse? OR has it always done it?

It could either be a worn valve, or a worn cylinder. Not sure on your kioti, but most modern tractors have a drop speed adjustment knob under the seat. If you raise the box blade and close that valve all the way off.....see if it still leaks down. If it does still leak down, the cylinder is worn. If it no longer drifts down....the valve is the culprit.

Machine has 180 hours on it it has been doing it for about 6 months doesn't seem to be getting worse I will try closing the adjustment knob and see what happens

Does the dropping affect you when operating the machine? As in does it drop fast enough that you have to be constantly readjusting?

They all will drop, the drop rate is the concern. When it affects operation of the tractor is when it's time to be concerned, otherwise, does it "really" make any difference?
