Adjusting the Rear Camshaft

A camshaft misaligned with the valve bank may cause
the following:
• No increase in ground speed in the No. 2 (transport)
traction selection
• The mow pedal will not stay depressed (in detent)
without foot pressure.
• Slow lift of the cutting units
• Slow or no drive to the cutting units
If one or more malfunctions occur, loosen the
rear camshaft mounting capscrews (Figure 42)
and relocate the cam shaft until the condition is
corrected. Tighten the capscrews.
Important: Readjust the mow/lift switch and
the lift and mow pedal height when the camshaft
adjustment is completed.

Adjusting the Lift and Mow
Pedal Height
To gain proper spool travel in the valve bank, adjust the
lift and mow pedals to equal heights as follows:
1. Place 1, 2 and 3 spools in neutral (center of travel)
and remove the transfer rod guard from the foot
panel (Figure 43).
2. Cam blocks

2. Loosen the jam nut securing the yoke on the front
of the long control rod. Remove the cotter pin and
clevis pin.
3. Move the adjustment lever by hand to level the mow
and lift pedals and adjust the yoke on the control
rod until the hole in the yoke lines up with the
adjustment lever hole (Figure 44).

4. Install the clevis pin and cotter pin. Tighten the jam
nut and install the transfer rod guard.
5. Actuate the mow pedal by hand. Be sure the lift
pivot under the pedals clears the stop welded to the
frame, thereby allowing full spool travel.
Leveling the Lift and Mow
Pedals
If the lift and mow pedals are not level when they are
in the neutral position, an adjustment to the lift pivot
is required.
