LEVELING LINKAGE FOR THE FRONT CUTTING
HEADS
WARNING
•
This procedure must be performed as
specified and only by properly trained
service personnel.
•
During this entire procedure the reel
enable switch must be in the off position.
Turning on the reel enable switch will
result in damage to the unit and/or serious
personal injury or death to you the
operator or bystanders
NOTICE
• The dimensions in figure 17 are factory
preset and the leveling linkage should not
need adjusting. After some time the
linkage may require some adjusting. If it is
required, only make adjustments on the
adjusting connector (See Fig. 17).
1. With the unit on a level surface
(recommend concrete surface), place
cardboard underneath all three of the
cutting heads.
2. An additional person is needed to stand
10’ (3 M) in front of the unit to check on
how level the front heads are when
lowering. Lower the cutting heads and
ensure the entire width of the front heads
are parallel with the level surface as the
heads touch the cardboard.
3. If they do not touch evenly, make an
adjustment using the adjusting connector.
Repeat procedure as needed until the two
front heads touch evenly on the level
surface.
NOTICE
• On the end of the leveling rod with the
springs and lock collar, the dimensions are
factory set and should never have to be
changed. (See Fig. 17)

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 anther 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.
