Easy part first, the pull buttons are actually petcocks that you turn. left opens, right closes. The bottom one is minimum level, and top is max, oil level should be between them.
As to Touch control, did you have it apart or off the tractor. The hand levers normally move easily. Is this the first time you have tried it?
Here is a link to the touch Control manual. It covers the cub, Super A, and C.http://www.cleancomputes.com/Cub/Blue%2 ... index.html
If you are referring to the rockshaft levers not moving, leave the fill cap loose and move the control levers forward and backward several times with the engine running, that normally removes any air. May need to remove the top plug (Allen head) where the lines attach to the block to let air out of system and check for oil flow. That plug is normally VERY tight. If you have not had it apart, and have not seen any signs of leak from the touch control, the seal/O ring on the pump is probably leaking the hydraulic fluid into the crankcase, and needs replaced. the job is similar to doing it on a cub, but does require different parts.
