I'm asking this for a friend which has a 1550 Oliver with hydra power,he was topping off all the fluids,he topped off the hydra drive and now he cannot get the tractor to move in any gear. Any ideas about what could possibly be the problem?

Thanks in advance.

Does the engine pull down when you try to release the clutch with no motion or just plain nothing happens? For the first part, the main transmission could be in two gears at once, meaning maybe a shifter fork problem. If nothing happens, first thing I'd look at is the coupling chain.

When I put tractor in gear it lunges forward a little but never moves in it's tracks. Fluid is full on all dipsticks. I just bought the tractor and when unloading from rollback the right rear tire was locked up it never broke loose Any help
and or advice would be appreciative.

Check to see if the coupler chain is missing between the rear and hydrapower. By dump luck it might have came off. The unit should operate in under if the clutches don't work that operate direct drive and should be driveable unless the sprag clutch is shot$$$$ If this is not the problem check and see if the shifter feels funny or the clutch pedal feels.
