860 clutch seems jumpy

bought our 860 in April, and have had issues with the clutch since we got it. short version is- neither my dad or I can slip the clutch to start out in any gear except 1st. its basically off/on in all gears except first. Can easily slip it in first to start slow. reverse is not as bad as 2nd+

the linkage is properly adjusted according to the manual.

my two thoughts here:
1- needs a new clutch
2- seat is in a bad position, which causes our leg to be in an awkward spot, which is why we can't slip it.

right now I'm leaning toward #2. no other signs of an aging clutch.

I think I remember someone posted that they spaced their seat back with square tubing? Anyone have the pic saved they can post? I couldn't find it with a search

I'm thinking that might help us, since right now our leg is so bent when at the top of the clutch pedal throw, that's why we cant slip it. I assume why we don't notice it in first or reverse is the gearing is so slow we don't get that "jump" like we do in other gears.
 
A bit of grease on the clutch surface will make the clutch grab.

If this is your issue, it MAY clear up with use so long as nothing is continuing to leak onto the friction material.

How does the PTO clutch work?

I had to build the seat up with the square tubing but I don't have any pictures. Pretty straightforward, cant hardly goof it up, just bolt up up and back a bit, and if you don't like it try it again.
 
Can you buy a button clutch for an 860? With live power the 860 has the two stage clutch. You buy a complete clutch assembly for
800 bucks
 
agree, some oil or grease on the clutch can make you get it all at once.
Keeping the clutch blocked down every time the tractor is not in use will help........until you find/fix where the oil is coming from.

seat....like said any old thing will work.
Handiest is that square tubing with all the holes.
(looks like roadsign tubing)
The hole spacing matches the seat bolt spacing.
lots of choices for where you want it.
no drilling...easy
 
Given the expense of replacing the two-stage clutch, I'd just live with it.

If you don't use the PTO, you can move the clutch linkage to the other hole in the clevis, which will put the pedal in a lower position but make it impossible to disengage the PTO clutch.

I haven't moved my seat, but have thought about it. I think all you need to do is get a piece of heavy wall 3 inch square tubing, five or six inches long, and drill a couple of holes in one side for the seat studs on the differential housing and two holes on the other side on which to mount the seat. That will raise the seat three inches and move it a couple inches back.
 
the PTO clutch works fine with no issues at all. Also, the tractor leaves no marks on the floor, so I have to think it is not an issue with grease/oil on the flywheel.

We do use the PTO, so I can't leave the clutch in the lower position, however I could switch it to that for testing to see if it helps at all.
