Welcome to the forum. I split this off into your own thread for better exposure.

Your description is a little vague. But with the these tractors there's alway the same few places to start when it comes to hydro issue,
Check fluid level,
Verify the free wheel knob is out all the way. If it was turned in recently after not being turned in for a long time, One of the valves might be stuck in the release postion.
Check for slop in the linkage, I usually lay underneath the tractor with the engine off and work the drive lever and look for any loose joints, on the transmission you will see a small bushing that rides in a cam groove, If this bushing can't spin freely it will cause wear and slop allowing the hydro to be jerky.
Let us know if you need anything explained in further detail.

120 owner and lover here. Others are pointing you in the right direction but I'd put my money on a partially stuck hydro release valve. What's the serial number of your tractor? I can get you info from the service manual on adjusting the hydro linkage.
