Its possible a relief is bad in the pump that controls the right forward movement. It could also be a bad pressure seal in the drive motor allowing the oil to by-pass. You can try swapping drive motors, see if the problem also moves. If it does, its a motor, if not its a relief/pump issue.

Thanks Tazza i was looking through the manual and it said that the hydropump replenishing valve isnt seating or the steering linkage needs adjustment do you think this could be the problem or not.Thanks for your time and trouble im new with this.

Its possible. If you had low power in both forward and reverse i would lean towards pump wear, but only one side generally is a relief or motor seal/shuttle valve.

What you could do, is reverse the hoses to the drive motor you think might be the problem, and see if it changes. I'm thinking it's a drive motor, with maybe a cracked gallery bypassing.
