[QUOTE="Tazza, post: 7844, member: 82"] To me it sounds like loose linkages to the hydrostatic pump. I do take it that this model is hydrostatic drive and not belt or clutch? Start by checking the linkages from the levers all the way to the pump and see if they seem tight. The bronze filter is only a problem with causing lack of drive, it will cause a lot of noise and little power. It shouldn't cause this issue.... The only other thing i can think of is the valve plate in the motor may be out of time. Has it always had this problem? and have you opened the drive motor? They need to be put together in a set position or dirive direction may be reversed. The bronze filter if you have one will be located in a square block on the hydraulic pump. There should be 3 hoses on the left, its behind the middle one. Remove the hose and fitting to gain access. This is me assuming it runs a vickers TA1919 pump like most of the early 7 series machines.
