I hope this is the right place to post this. I did a search of the forums and found none for 806.
My tractor won't move. It sometimes will go if I bleed the pump on the side. Is this perhaps a pump problem or Torque amplifier problem.
Any help will be greatly appreciated.

What pump are you bleeding?

The last time it happened I bled the one on the bottom of the left side. I am not sure it wasn't a coincidence.
Thank You

will it move with the ta in low or high? do all the hydraulics work?
T/A's usually only lose one side at a time. unless the hydraulic pump or control valve
dies.

You have two problems.
One, an hydraulic problem in the Multiple Control Valve circuit related to an air leak, worn pump, blown gasket, oil quality/quantity, or a plugged filter.
Two, a failed sprag within the TA assembly itself. The TA should default to TA mode (low) and drive on the sprag without any hydraulic oil flow or pressure if the sprag is sound.
