Small Engines (Lawn Mowers, etc.): Craftman lawn tractor will not start, thought starter, battery terminal


Question
Mower model no. 917.272056, Kohler 16hp CV460. 5 years old. One mow, engine trouble turning over to start (thought starter going?). The next mow, on start, engine struggled to turn over,turned very slow, did not start. Then just clicking. Now nothing with turning key, sometimes a "hum".

Replaced battery, solenoid, plug, checked fuse. Connected positive battery terminal to starter and starter turns, but doesn't turn motor, just sounds like starter drive is turning.

Ignition switch?

Answer
 Hello Tim:

 Remove and Check the Starter. From your Description it Sounds like the Starter Drive Gear is Stripped and the Starter May be Dragging/Binding when it is Engaged with the Flywheel.
