Riding mower won't go forwards or backwards. It's about 6 years old and I've never had an issue. Even though it's old, I purged the hydrostatic system just for haha's. It didn't work. Drive belt is taunt and engine runs fine and blades will engage. Any suggestions as to my next step - short of buying a new mower because it's a transmission issue?
One of the things you usually get with price is quality of the hydro trans including durability of the gearing. I'm not sure which trans model they used here. Still, they can be replaced probably cheaper than a new mower.
