In most cases the hydrostatic drives are not made by the company tractor or lawnmower.
This is in the owners manual.

Hydrostatic Transmission
The hydrostatic transmission is sealed at the factory
and is maintenance free. The fluid level cannot be
checked nor can the oil be changed. Always keep the
area around the transmission cooling fan free of grass
and debris at all times

How to Change the Hydrostatic Fluid in Cub Cadet Lawn Mower

I hope that this can help. Tom

If it's a hydrostatic transmission, I would have the transmission looked at. You may need to "purge" the system and check the fluid level.

The ones I've done called for the drive disconnects (the rod or lever which allows you to roll the tractor when the engine is shut down) to be in the flow bypass position. They also wanted the wheels off the floor, then the engine to be started, & the direction control to be worked SLOWLY to the front & rear positions 10-12 times. Then put the bypass valve back in its 'drive' position, fire the engine again & repeat the slow cycle of the direction control. The unit SHOULD be quieter now & perform better, but double check the oil level because expelling the air may have dropped it too low.

Check the hydraulic oil level for the hydrostat drives(if it has a reserve tank located under the seat. Some ZT's don't have the reserve tank. Don't over fill that tank. 1/4 inch above the bottom is all it needs.)

Also, check the steering arm bolts. Very often they work themselves loose and the arm doesn't pull the valve rod that controls the hydrostat unit.

This does not sound good if its still under warranty get it back there asap... sounds like a lazy drive weather its juat a faulty drive or your hydro pump not feeding that side, it should not be unservicable after 90hrs... even if its out of warranty get it fixed asap as the metal may spread to your pump or other drives and that will be very expensive.

I hope this will help you...under the side panels on each side of the mower, there are "reverse lockout safety switches", they are supposed to stop the blades when both handles are pulled back. If one or both of the switches are out, the deck will not engage. Also, under the right side panel (when sitting on seat) there should be 3 relay switches, the one closest to the motor controls the PTO., if this is out, the PTO will not engage.
