hustler super z

[skeeter21i]

i need a little help i have a hustler super z with 390 hrs the left hydro is real jerky /slipping maybe when you first start moving forward its fine after you get moving and it does it in reverse also but not near as bad does this sound like a bad left hydro thanks

I would check fluids and purge air out of the system. Also, check the belt and idler pulleys.

thanks for the info i did all that and no luck i took a shot and took the hydro apart i have never had one apart but from some videos i have watched the place to look is the valve plate for a grove and if you can hang a fingernail on it its bad and mine does have a deep grove so im hoping this is my problem and not the wheel motor here is a pic of the plate
