TRACTION PEDAL SPEED LIMITER
Cutting quality is better at speeds well below the trans-
port speed of the tractor. An initial mow speed of 6 mph
is set at the factory and should be satisfactory for most
cutting conditions. Local turf conditions may respond
better to different speeds (Figure 2C-3).
Figure 2C-3. Traction Pedal Speed Limiter
To adjust the mowing speed limit, loosen the jam nut
and adjust the stop screw (Figure 2C-4) up to reduce
speed or down to increase speed. Tighten jam nut to
hold adjustment in place.

MAXIMUM TRANSPORT SPEED
Before making speed adjustments at the pump, check
that the engine is running at full rpm under load and the
throttle is adjusted correctly.
NOTE:
The following adjustment is a forward transport
speed (Figure 2C-5). See Traction Pedal Speed
Limiter for adjusting mowing speed.
Figure 2C-5. Traction Pedal Linkage
1. Check the neutral adjustment and adjust if neces-
sary.
2. Place the traction pedal speed limiter in the trans-
port position.
3. Disconnect the rod end from the traction pedal.
4. Push the traction pedal forward until it touches the
floor panel.
5. Push the return arm on the drive pump back until it
hits the internal stop on the pump housing. This
position places the pump at full stroke.
6. With the return arm and traction pedal at full for-
ward stroke, adjust the rod end in or out until it
aligns with the link arm.
NOTE:
Additional adjustment may be made on the rod
end at the pump if necessary.
