My son has a Scotts 17.5 hp 42" cut riding mower that was formally mine. It has 188 hours on the meter.
There are a couple of issues with it now:
1. when he starts it up, the engine seems to pulsate rpm's until it is warmed up. Then it runs normal.
2. when he is in deep grass, the unit runs rough, increased vibration in the unit.
Anyone have any thoughts?
