Drive Clutch Control Adjustment
(Models 820
Thru 829)
Use the adjustment wheel located on the underside of 
the clutch control housing to tighten the drive belt, if 
mower does not self-propel with the drive clutch control 
engaged, or if drive belt is slipping (unit hesitates while 
engine maintains the same speed). See Figure 10.
In addition, the adjustment wheel may also be used to 
determine the position in which the drive clutch control 
is engaged. If it is more comfortable to have the drive 
engaged with the lever further away from the handle, 
tighten the drive belt.
Make certain to retest the unit for neutral as instructed 
in the Operation Section. Move the adjustment wheel in 
the opposite direction to loosen the drive belt if 
necessary. 
NOTE: For some people the drive clutch control may
not be in a comfortable position. You can adjust the
handle out by tightening the adjustment wheel.
