Perform this check with all of the spacers and springs above the caster wheel
arm. This will place the caster wheels in their highest position and provide the
lowest cutting height for the mower.
1.
Raise mower with tractor hydraulics to 406.4 mm (16") at dimension C or
maximum height of tractor lift, whichever is less.
2.
Pivot both front caster wheels forward and check that there is clearance
between caster wheels and tractor tires.
3.
If there is interference on models PRD6000E and PRD7200E, mount
front casters in the outer position. If interference continues, adjust mower
hitch plate (E) as shown in Figure 8.
NOTE: On model PRD8400E, caster wheel width is not adjustable; see tractor
operator's manual and adjust tractor wheels to narrower spacing.
FRONT ROLLER (OPTIONAL)
The caster wheels and side skids effectively reduce scalping in most cases.
However, you may encounter areas where the caster wheels and/or side skids
drop into depressions and allow center of the mower to contact ground and
scalp. An optional front roller may be installed to minimize scalping. See page
23.
OPERATING TECHNIQUE
Stop power unit and implement immediately upon striking an
obstruction. Dismount power unit, using proper procedure. Inspect and
repair any damage before resuming operation.
Power for operating mower is supplied by tractor PTO. Operate PTO at 540
rpm. Know how to stop tractor and mower quickly in an emergency.
If mower becomes plugged causing belt to slip for over two seconds follow
these steps:
1.
Maneuver equipment into a previously cut area and allow mower to clear
accumulated material.
2.
Continue running at least two minutes, allowing pulleys to cool. Stopping
the mower in contact with a very hot pulley will bake and ruin belt.
Proper ground speed will depend upon the terrain, the height, and type and
density of material to be cut.
Normally, ground speed will range from 3.2 to 8 Km/h (2 to 5 mph). Tall dense
material should be cut at a low speed; thin medium-height material can be cut
at a faster ground speed.
Always operate tractor PTO at 540 rpm to maintain proper blade speed and
produce a clean cut.
Under certain conditions, tractor tires may roll some grass down and prevent it
from being cut at the same height as the surrounding area. When this occurs,
reduce your ground speed, but maintain PTO at 540 rpm. The lower ground
speed will permit grass to partially rebound.
In general, lower cutting heights give a more even cut and leave less tire
tracks. However, it is better to cut grass frequently rather than too short. Short
grass deteriorates rapidly in hot weather and invites weed growth during grow-
ing seasons. Follow local recommendations for the suitable cutting height in
your area.
Operating Tips
Inspect and clear area of stones, branches, or other hard objects that
might be thrown, causing injury or damage.
Extremely tall material should be cut twice. Set mower at a higher cutting
height for the first pass. Then cut at desired height, 90 degrees to the first pass.
Remember, sharp blades produce cleaner cuts and require less power.
Analyze area to be cut to determine the best procedure. Consider height and
type of grass and terrain type: hilly, level, or rough.
Plan your mowing pattern to travel straight forward whenever possible. Mow
with uncut grass to the right. This will distribute the clippings over the cut area.

Operating on Uneven Terrain
Do not operate or transport on steep slopes.
Do not stop, start, or change directions suddenly on slopes.
Use extreme care and reduce ground speed on slopes and rough ter-
rain.
Watch for hidden hazards on the terrain during operation.
Pass diagonally through sharp dips and avoid sharp drops to prevent hanging
up tractor and mower.
Practice will improve your skills in maneuvering rough terrain.
MOWER REMOVAL & STORAGE
1.
Disengage tractor PTO and raise mower with the 3-point hitch.
2.
Disconnect mower driveshaft from tractor PTO.
3.
Collapse driveshaft as far as possible and store it in PTO hanger bracket
to prevent ground contact.
4.
Before extended storage, see page 14 for cleaning instructions.
5.
Place blocks under mower side skids. Lower mower onto blocks,
disconnect mower from tractor 3-point hitch, and carefully drive tractor
away from mower.
