MOW SPEED______________________________________________________________
Cutting quality is better at speeds well below the transport
speed of the mower. An initial mow speed of five to six mph
is set at the factory and should be satisfactory for most
cutting conditions. Local turf conditions however may
respond better to a different speed.
To set mow speed, loosen jam nut (A), and adjust stop
screw up to reduce speed, down to increase speed. Tighten
nut to hold adjustment in place.

BELT ____________________________________________________________________
Inspect and adjust new belt after first ten hours of operation.
Adjust every 100 hours thereafter.
Adjust alternator pulley so belt deflects 1/4" to 5/16" (6 -8
mm) with a 20 lb. push at midpoint between pulleys. See
engine manual.
If tension is incorrect, loosen alternator mounting bolts (B)
and adjust alternator until proper belt tension is achieved.
