MOW/TRANSPORT SPEED CONTROL
When cutting heads are raised completely, the
wheel drive speed range is 0 7.5 mph (0 12 Km/
hr). Speed is controlled by use of the direction/
speed control pedal as described in control pedals
section.
When cutting heads are lowered, the forward
movement of the direction/speed control pedal is
restricted by the automatic mow speed control
linkage (the bellcrank stop screw contacts the foot
pedal tab which rotates the pedal upward. This in
turn reduces the ground speed of the unit for
mowing). The mow speed range is 0 3.8 mph (0
6.1 Km/hr).
ADJUSTING MOW SPEED
To determine mow speed, run a time check on how
fast the unit travels in a distance of 50 (15.24 M).
Prepare a level surface with enough room to start
and end beyond the 50 marks.
Place a stake in the ground where you want to begin
timing the unit. Measure and place another stake at
a distance of 50 (15.24 M). Lower the cutting heads
and press the direction pedal forward so the unit is
traveling at full throttle (the cutting heads should be
in the neutral position when timing the unit).
Begin timing the unit when the center of the front tire
aligns with the first stake. Stop timing when the
center of the front tire aligns with the stake placed at
50 (15.24 M). Estimated time for 3.8 mph (6.1 Km/
hr) will be approximately 8.8 to 9.2 seconds. If there
is a significant difference in the times listed above,
you can adjust the mow speed as follows.
