So...Other than this annoying issue...tractor runs and works great.
2013 Kioti DS3510 w/863 hrs. Float doesn't seem to work unless I hold the lever in place. This started up earlier this year but the tractor isn't used that much so not really an issue until now.
The lever will somewhat stay in the float position but it does have a little slop. That little slop is applying down pressure to the bucket so no float unless I hold the lever all the way up. It is in the detente and feels like it should be in float mode but it drops a little and hydraulics are activated. I have attached a couple of videos.

Thoughts? Thanks all!

I maintain all vehicles at my place but have never gotten into the breakdown of hydraulic valves. Is there a diagram somewhere showing parts and layout etc? Or can you clarify "end cap"? More than able to do the job just don't like going in blind.

Thanks!

OK So I am still having this problem. I have taken the boot off a couple of times. Once when one of the screws for the joystick support bracket came loose. Got that taken care of.
I checked all the other screws and everything is snugged up.
As before I can hold the stick in the float position no problem but now it wont even stay in that position. it feels like it will hold then just drops out.
I have searched for parts listings/diagrams and the closest I have found is for the KL402 loader. Looks similar on the joystick portion but the valve body is different. This cant be that hard to fix... at least I don't think it is... but need guidance. Haven't messed with hydraulics much.
HALP! Thanks all!

You need to remove the spool cap on the far side of the valve body from the joystick. The float spool controller will be the longer of the 2 spool caps. In the cap, there will be 3 ball bearings that engage is a slot in a spool washer. If the washer gets warn, the bearings won't lock in the groove. Often, you can spin the washer so the bearings have a fresh lip to lock in and re-assemble the spool cap. Make sure you grease the bearings and spring well before assembly. The grease will keep the 3 bearings in the holes at the end of the spool controller.

Hope this helps,
