Wheel Clutch Traction Drive System; General Description; Disassembly - Toro Power Max Service Manual

GENERAL DESCRIPTION

The Freewheel Steering system is used on 28" models.
Handle mounted triggers allow clutching the wheels
simultaneously or independently, so one or both wheels
can "freewheel." This feature makes turning, reversing,
and traction control simple and effi cient.
When the drive is engaged, it is engaging the friction
wheel. The hex shaft turns and drives the chain(s) to the
32 tooth gear in turn driving the 44 tooth gear powering
the wheels. Each wheel is declutched by engaging its
handle mounted trigger; this pulls the clutch cable, which
rotates the shift collar. The shift collar, following a cam, is
forced outwards, toward the wheel, in turn, pushing into
the spring loaded pawls to disengage the 11 tooth pinion
gear from the 32 tooth gear.
