knob. The differential will then lock giving continu-
ous power to both rear wheels. While in the pulled 
position, the differential lock will remain engaged.
IMPORTANT: Engage the differential when the left and 
right side wheels are turning at slightly different speeds. 
WARNING: To avoid transaxle damage, 
injury, or turf damage, go slow when 
operating vehicle with differential lock

reduced.
