when the gauge is inserted and removed, and make
any necessary adjustments by tightening or

armature may vary even after performing the adjustment
procedure. This is due to dimensional variations on
component parts, and is an acceptable condition.

blades and mower drive belt should come to a
complete stop within five seconds after the electric
PTO switch is turned off.
7. Perform the BLADE BRAKE CHECK found in the
Maintenance section. Mower blades and mower drive
belt should come to a complete stop within five
seconds after electric PTO switch is turned off.
