Hydraulic Pump Question

DyslexicDancer · May 30, 2022

I'm a new tractor owner and I think I messed up my Kioti CK2610 yesterday

I was on my tractor using the brush hog and somehow one of my remote hydraulic levers got pushed forward, it took me some time to figure out that this had happened. I only noticed when I stopped brush hogging and reduced the engine to idle, I noticed the engine making a funny pulsating noise when it was at idle and then saw the lever was pushed forward. When I put the lever back to the middle (N) setting the engine went back to sounding normal

One of the remote levers I have will go back to the center on it's own and one stays in the position you put it, it was the lever that stays in position that was pushed forward, so for a while the hydraulic pump was trying to push pressure to the remote, but nothing was plugged into the remote.

My tractor is still new, under 50 hours, and now I notice that my bucket will not stay up like it used to, it will very slowly will fall to the ground (over the course of 12 hours) if I leave the bucket raised whereas before it would stay up overnight without any issue. So I think I may have damaged a seal somewhere in the hydraulic system or possibly damaged the hydraulic pump.

The tractor seems to act normal, no reduced power and I've not seen any leaks yet, the only thing is the bucket slowly falling down if left up.

Any idea on what damage I may have done and if it will be expensive to fix?

I do not think you have a problem. It is not uncommon for loaders to leak down over time. The loader valve is a separate circuit from the remote valve. Most likely it is plumbed before the remotes.

You would do yourself and your tractor a lot of good if you did not leave the loader and implements raised when you park the tractor. Always lower everything to rest on the ground when you stop.

I never leave anything up, ever. I mean if I step off to get a wrench out of my truck, I let all down. Saw two little boys that were not supposed to be there, one let the bucket down on the other and killed him. They were not related to the owner, he didn't even know them. Kids weren't even in their teens, I'm thinking 10 or 11. I don't ever leave anything up on front or rear. If I'm not on the machine it's set down on ground. I worked at a dealership as a mechanic. If they caught you with something up and not supported, you was fired on the spot. It's important.

Ain't that the truth! Even kids that are not supposed to be around seem to appear out of nowhere, and invariably will try to operate a control.
I left a tractor that was at a county fair ready to tow a float with everything grounded, tractor off, brakes set, etc...
Sure enough, kid jumps on and cranks the engine over. Fortunately I was right there, but the keys came out after that one.

Yes sir, gotta protect them from themselves.
