TRACTION PEDAL SPEED LIMITER __________________________________________

Cutting quality is better at speeds well below the
transport speed of the tractor. An initial mow speed of five
to six m.p.h. 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.
