Exmark hydro. Strange problem?

[HenryB]

On my 48 Exmark TT hydro I've got some strange tracking. At half speed it tracks to the right and at full speed it tracks to the left.:dizzy:At either speed it tracks to the right downhill and the left uphill. Reverse seems pretty even and both sides feel strong no delay or noises. Help

Buy a TORO> Just kidding. Try adjusting the tracking. Follow the instructions step by step. First make sure the belt and idler arm is free and none of the linkage is sticking. I sprayer WD40 on all pivot points to zero in if there is a binding problem.

Do you have proper tension on the hydro pump belt?

along with all the things mentioned already, check your pump control arm set screws that hook it to the pump shaft. They are the small square head type of set screws that are known to loosen up on the turf tracer series and cause strange/changing tracking.
