Kioti NX6010
Hi folks, my patience is just about gone.... argghh :) long post, trying to provide as many details as possible.

Finally took my '17 Kioti NX6010 back to dealer to resolve the hydraulic hitch 'bouncing/ bucking' issue when using the 3 pt hitch to run my new Woods 720 Bush hog.

Since day 1 of using the Woods BB720 bush hog the tractor started 'bucking'. I think I posted here about it, never figured it out. Called Kioti Dealer last year, they said they have no idea. After mowing field again this June I decided I'm done with this, it has to get figured out & fixed!

Brought Kioti NX6010 in to dealer to resolve June 20, 2020.

Immediately they found the MEC Valve was defective, causing the 3 point arms to not be able to hold at specific heights or position, they ordered a new MEC Valve, they installed the new valve and it apparently did not solve issue. They ordered a second new MEC valve, that too did not resolve issue, and now the arms don't go up or down at all. The arms / 3 point went up and down with original failed valve in place, but now will not move with either of the two NEW MEC valves.

They removed the entire hydraulic system group from under seat area and have it out next to tractor. Kioti Product Manager is now saying to disassemble the entire linkage assembly to see if the linkages or 'arms' are bent or out of proper radius (by lying them on a straight bench surface).... this is going to take another 5-6 hours at best according to dealer... putting the resolve out to next Wednesday July 29, 2020 .... 6 weeks from date of bringing it in. So next Wednesday if all stars align they will know if the linkages are bent or normal. If bent or 'out of radius' then they'll order new parts and who knows how long that will take... if they are not bent or out of radius then unsure what next steps are...

I called Kioti customer service (877-465-4684) .... they unfortunately were not helpful.. They just said they await orders from the dealer.... they cannot order the entire assembly to be replaced nor can they proactively any send parts to the dealer in anticipation of finding the root cause. Customer service did not ask who I was, VIN #, who the dealer is or any details about me or issue whatsoever (ex. open a case). Quite disappointing.

And oh by the way, here's a tidbit the dealer shared "Kioti only takes parts back in November" in other words the dealer would have to keep any parts not used on the books until November, and this dealer/owner (Powersports in Conway, NH) will not allow that.

Buy a new Kioti for $40k.... have it sit at dealer for 6 weeks June & July and now going in to August.... seriously there has to be some recourse here.

Pics of the removed hydraulic unit attached.

1. Any thoughts on resolving this bizarre issue, parts or troubleshooting ideas I can pass along to dealer tech?
2. Any ideas how to get Corp Kioti to send along a full Hydraulic System Group / Power Lift body unit assembly to dealer to get the issue resolved?
3. Any ideas how to escalate / resolve ?

thank you,
Erik

About the best Kioti people I know would be Jon Parks in Littleton, and Orchard Hill down in MA, I bought a Subaru as well as a 2500HD from Profile, service from both dealerships was horrible - very happy I did not get the Kioti from them, stop by or give Jon Parks a call, they are a great family business, always happy to help, Jon's been a dealer for a long time maybe he can at least let you know what the issue is, most likely the've dealt with it, I know they get a lot of work from our area.....

I would of went for control valve 1st or the piston seals. The piston is not holding pressure and could be as little a o ring leaking by under a heavy load.

Thanks BrkMstr, I'll definitely keep Jon in mind or just give him a call today. I knew service would be an issue when I bought it 3 years ago...I bought the 2" thick service manual to do as much as I possibly could or needed to over life of owning it... so far this is only thing I've had to bring it in for... thanks for the pointer, very useful.

Thank you Leejohn. I'll bring this up on my *daily* visit when I go there today. The original MEC valve was broken, so that's why they were focused on that at first. I'll see if they can do a check on the control valve & piston seals. thanks!

Ditto on RS piston seal or thermal relief valve failure

thanks Jim - I'll add thermal relief valve to the list when I go there this morning. They must love seeing me show up daily now :)

* what does "RS" stand for ? thank you!

July 27 2020 update:
I mentioned the rings, valve and thermal relief possibilities to the tech & service manager... refuted all of those saying hydraulic fluid is getting up in to the chamber/reservoir of the hydraulic system group. So they are going to disassemble the linkages in the hydraulic system group and look for bent or 'out of shape' pieces.
Closed today (mondays) so will go in person yet again tomorrow to see what they see/say. thanks all.
