Is that in August? I may just do that.
Yes, unless we are still under lockdown.

There are two ways to get enough Cubs. One is to continue to accumulate more and more. The other is to desire less.

Re: Touch Control no longer lowers deck
Hi,
I would look and see if the Touch Control block is leaking from the front, if fluid runs down on the clutch housing. If it leaks from the front of the unit, the Control Valve o ring could be wornout, and need replacing.
If it just the Control Valve o ring leaking, and there is no leak at the rear, or head end, there may be no need to rebuild the whole unit.
The Touch Control cylinder and piston could be leaking, that is higher up than the control valve.
Use a light, and try to see if, or where it is leaking.
Below is a listing at TM Tractor showing a new Control Valve o ring, it is a Case IH part, it says. There is a pic there showing where it is.
They have said on here that the o ring is a special size.
The valve pulls out the front of the block. You don't need to remove the Touch Control head to replace the control valve o ring.
You may need to remove the 4 bolts that hold the unit onto the clutch housing, the tubes, and the control lever rod, and turn it to the left to get the valve out. You have to lift it some, the bolt heads for the bottom cover would keep it from turning it to the side. Or you can remove the unit and set it on your work bench.
Drain the system first, like the owner's manual says, remove the filler plug, then the drain plug.

Whenever disassembling a Touch Control, it should be clean. Don't allow any dirt or grit inside the unit.
If you need to replace the o ring, clean the area well, and use plenty of Hy-Tran fluid on the o ring and valve, when putting the o ring on the valve, and when putting the valve into the unit again.
Feel the area around the hole for the valve in the block, be sure it is smooth and clean.
Any roughness can cut the new o ring.
When you get it to work, remember to fill the unit the last time with the arms in the rear or down position, like the Cub owner's manual says.
Below is a pic from TM Tractor of the front of a Touch Control, with the rockshaft removed.
The control valve is at the lower right, right in the pic.
The piston is in the upper part of the pic.
