Cub Touch Control acting funny

[nadz]

I have a question to ask the group, I just registerd so I hope this is the right spot.

I have 51 cub (my 1st cub) that I got about two months ago with 42" woods belly mower.
and it seems the touch control is acting a little 'odd' I have never had a
cub before, or played much with hydraulics so let me describe the problem.

It has both a upper and lower stop for the touch control lever, and it
always lifts the deck to the same upper position (and it is not hitting
anything under the tractor)

It always lowers smoothly but sometimes it lowers all the way to the ground
and sometimes it seems to stop a little short.

If I move the lever its full travel all way it will rise smoothly, but if I
try and 'inch' the deck up I end up pulling it back quite a bit and the it
tends to 'hop' up. but if the deck is up I can usually slowly lower it down
the length of travel of the touch control lever.

I read through the owners manual and it didn't give me any clues, I start on
the blue ribbon service manual for the touch control tonight.

any and all advice, stories, guesses, fixes, and comments welcome

Hello Nadz,
Welcome to the board, this is the right place, the people here are always helpful and kind.
The first thing to do is make sure the fluid level is correct, if it is low and the fluid has air bubbles in it, it can cause the symptoms you describe.

Well, I posted to this a while ago but must have forgotten to press the submit button so here we go again. On the left upper side of the hydros is the filler, check to see ifn' you can feel or see fluid. If not add enough HI-Tran to accomplish the above. Then with the filler still off, cycle the hydros all the way up and all the way down between 10 and 12 times to remove any air that might be in the system. As one of the respected board members says: Check the easy things first. Good luck and keep us posted.

I'm not a touch-control guru but that almost sounds like follow-up linkage maybe out of adjustment. Purely a guess though.

NADZ, I see you found us. Welcome to what in my opinion is the best discussion forum on the internet. You'll find lots of help here.

Nadz welcome to the cub forum. I think i would try the fluid first also.
