<font color=red>How often do you change it?</font color=red>
The impression I got from Power Trac was "when it gets dirty" which is basically never if you keep it clean. Apparently it being motor oil it doesn't require changing like hydraulic oil does.
I asked Power Trac when I purchased my tractor and they said not to change it unless it gets dirty wich may never happpen. This conversation came up when I asked about changing my hydralic fluid to synthetic at the next scheduled change.

after my fiasco with my stump grinder i moved to mobil one for both: the engine and the hydraulics. kohler for the same engine lets us on the zturn exmark change the oil every 100 hours.
