Checking the Tire Pressure
Service Interval: Before each use or daily
The correct air pressure in the front and rear tires is 83 to
103 kPa (12 to 15 psi).
Important: Maintain even pressure in all tires to ensure
that contact with the turf is uniform.
Checking the Torque of the
Wheel-Lug Nuts
Service Interval: After the first hour
After the first 10 hours
Every 250 hours
Torque the wheel-lug nuts to 94 to 122 N∙m (70 to 90 ft-lb)
after 1-4 hours of operation and again after 10 hours of
operation. Torque every 250 hours thereafter.
WARNING
Failure to maintain the proper torque of the wheel
nuts could result in failure or loss of a wheel, and
may result in personal injury.
Torque the front and rear-wheel nuts to 95 to 122
N·m (70 to 90 ft-lb) after 10 hours of operation.
Torque the nuts every 250 hours thereafter.
Adjusting the Height of Cut
Important: The rotary cutting deck cuts approximately
6 mm (1/4 inch) lower than a reel cutting unit with the
same bench setting. Therefore, it may be necessary to
have the rotary cutting deck's bench set 6 mm (1/4 inch)
above that of reels cutting in the same area.
Important: Access to the rear cutting units is greatly
improved by removing the cutting unit from the tractor.
If the unit is equipped with a Sidewinder®, sidewind the
cutting units to the right, remove the rear cutting unit,
and slide it out to the right side.

2. Loosen the bolt securing each height-of-cut bracket to
the height-of-cut plate (front and each side)
3. Beginning with the front adjustment, remove the bolt.

4. While supporting the chamber, remove the spacer
(Figure

5. Move the chamber to the desired height of cut and
install the spacer into the designated height-of-cut hole
and slot
(Figure
6. Position the tapped plate in-line with the spacer.
7. Install the bolt finger-tight.
8. Repeat steps 4 through 7 for each side adjustment.
9. Tighten all 3 bolts to 41 N∙m (30 ft-lb). Always tighten
the front bolt first.
Note: Adjustments of more than 3.8 cm (1.5 inches)
may require temporary assembly to an intermediate
height to prevent binding (e.g. changing from 3.1 to 7.0
cm (1.25 to 2.75 inches) height of cut).
