i have a bob-cat zt 100 series mower with a kohler ch 730 motor, i have charging issues,i replaced the regulator/rectifier and it still eats battery,it charges when running but whe i put a load on it (turn blades on )the charge goes down,it will run with blades on for about 2 hrs then the blades kick off (mower still runs ) but i cant turn blades back on not enough juice,
 
get a volt meter, and unplug the connection at the regulator. Take an ac reading across the white wires, should be over 28
 
Your electric PTO clutch may also be going. High resistance in the clutch may be causing a higher than normal draw on the battery.
