3.7 MOW SPEED _____________________________________________________________
Cutting quality is better at speeds well below the transport
speed of the tractor. 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.
