Service the clutch and trans. Haynes or clymer make a shop manual for ur model. Umust do monthly maintenance

I don't know of two hooks on each end, but it sounds as if parking brake release has broken. When this happens the brake is spring loaded to engage. You can remove the spring for that side and tie the arm back so it can be moved. Check the right side on side of that hydro unit, there should be an curved alloy arm with gear like notches on it held against the brake unit. Order parts immediately before using for safety.

May be low on hydraulic Oil.
Theres also a nut that releases the hydro pressure make sure it is not loose. Make sure there are no leaks. And make sure on the back of the mover that the hydro release is not pulled. If there are no issues then there is a issue with the hydro pump and yes the repair is costly. A replacement pump is roughly $250-300 dollars.

The two pins in the brake caliper are probably corroded including the caliper itself. Needs to be removed, pins removed, cleaned, and reinstalled. The caliper holes themselves needs to cleaned by reaming them out without enlarging beyond their normal size. A second option would be just replace the caliper assembly.

Either your drive belt has come undone, or the seat wiring is not secure

take a good look at the linkage

You have to do one more thing to move this tractor without the motor running.
It takes two people to move the Revolution. One needs to sit on the seat and hold the forward pedal down. It will then freewheel.
So, brake off, both hydro release levers pulled (do NOT pull hard or you will break the springs) and the forward (right hand side, big pedal) pedal pushed down.
Any other question? I know this unit pretty well.

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.

I can't be for sure if these are auto set margins, but it sounds like they might be. If they are, first move the carriage as far to the right as you can. Hold the Left Margin Set (not Margin Release) lever as you move the carriage all the way to the left. Release the Margin Set Button or Lever. Now hold the Right Margin Set Button or Lever (not the Margin Release), and move the carriage all the way to the right while holding the Margin Set. Once the carriage is all the way to the right, release the Margin Set. Move the carriage to the place you want to set your left margin. Hit the Left Margin Set and then release. Move the carriage to where you want to set the right margin. Hit the Right Margin Set and release it. It gets confusing, but Margin Release does not set margins. Its sole purpose is only to bypass the margins. Hope this helps.
