Are you having a mechanical issue or a hydraulic issue?
Check the level of hydraulic fluid in the block, with the piston retracted.
Hi,
The Touch Control has to have fluid to work, if the fluid gets too low, it won't work, or work right.
Below is info for checking the Touch Control fluid level, if you need it.
Below are pages from the 1955 Cub operator's manual telling how to fill, or change the Touch Control fluid.
If the fluid is low, people on here have said it can have air bubbles in it, then it is better to drain it and change it. The drain plug is the small plug on the right side of the unit, at the bottom.
The filler plug is the large plug on the left side of the unit, near the top.
Always check the fluid level with the arms in the rear, or down position.
The fluid level should be to the filler plug hole, the manual says.
The fluid rises in the unit as the arms go to the rear. If you check it with the arms ahead, it will look low, even if it has the right amount.
The 1st page below shows the parts of the system, and where the filler plug is.
The 2nd page has info for checking or changing the fluid, and shows where the drain plug is.

If you drain the system, remove the filler plug before the drain plug, to let any pressure out of the system.
Nowadays the system uses Case IH Hy-Tran fluid, it is sold at Case IH dealers. It is thin hydraulic fluid.
There are other brands, be sure it works with IH hydraulic systems before buying it.
If you change the fluid, be sure to do what the 2nd manual page says in paragraph 4, to remove the air from the system. The arms should go through their full travel 10 - 12 times.
