Losing power on a 128

[Donnie Pastoria III]

Hello everyone,
I was given a Cub Cadet 128 with a Kholer 301A engine, to try to fix up. It started, needs tuned up, but when I jumped on to feel it run I ran into a problem. The tractor starts to lack power in 2nd gear. It will only run in third on flat ground, absolutely no hills.

I can figure out most things with the use of a service manual and videos, but don’t know anything about transmissions or the like.

Sounds like a clutch issue.
Worn clutch disc.
broken main spring.
Not properly adjusted..

Time to break out the service manual and bone up on that department.

Thank you for the direction to start studying.

Welcome Donnie!
David is right. Do your studying, and in no time you will have that 128 running good again.
Only thing I could add is, just be patient.

Does the engine lack power, or is the tractor's forward speed slow down with no change in engine speed?

The engine speed does not change, just the tractor. It will be in gear, but have no power to get forward momentum. If I’m on complete flat ground I can run in 2nd and 3rd gear no problem.

Have you checked the clutch yet?
