TRACTION PEDAL SPEED LIMITER __________________________________________
Cutting quality is better at speeds well below the
transport speed of the tractor. An initial mow speed of 5
to 6 mph (8 to 9.6 kph) 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
(Q)
and adjust stop
screw up to reduce speed, down to increase speed.
Tighten nut to hold adjustment in place.
