Hi Nath,
Thanks for your reply.
By Hydrostatic do you mean heel and toe pedal for reverse and forward? If so, yes that's what I have.
On flat ground I can reverse albeit fairly slowly and it will cut as long as the reverse cutting switch has been thrown, if not the safety cuts in and the deck disengages. However when challenged with an upward slope it either struggles or won't move at all even when the deck is disengaged. The engine revs don't change there is just no drive to the rear wheels.
Cheers
Bob W.
