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. Cut mate-
rial higher the first pass. Then cut at desired height, at
90° to first pass.
Remember, sharp blades produce cleaner cuts and
require less power.
Analyze area to be cut to determine best procedure.
Consider height and type of material and terrain type:
hilly, level or rough.
Plan your mowing pattern to travel straight forward
whenever possible.
Optional Blade
The mower is equipped with free-swinging suction type
blades as standard equipment when shipped from the
factory. If you are operating in a sandy area or where
high abrasive wear occurs and causes damage to the
fin of the standard suction type blade, an optional low
suction type blade is available.
Optional Front Roller
The tailwheels and side skids effectively reduce scalp-
ing in most cases. However, you may encounter areas
where the tailwheels and/or side skids drop into
depressions and allow center of mower to contact
ground and scalp. An optional front roller may be
installed to minimize scalping.
Uneven Terrain
Do not operate or transport on steep slopes.
Do not stop, start, or change directions sud-
denly on slopes.
Use extreme care and reduce ground speed on
slopes and rough terrain.
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.
TRANSPORTING P990-3 MOWER
Either the standard ratchet adjustment link or optional
hydraulic cylinder and transport bar must be installed
when transporting mower.
A transport bar, to be used in conjunction with the
hydraulic cylinder, is furnished with each P990-3
mower. It must be installed when the optional hydraulic
cylinder is used to control cutting height.
Transport Bar Storage Position (Figure 6)
When not in use, the transport bar (3) should be piv-
oted to the rear, away from the cylinder, and the lock
pin should be installed in the hole and secured with
hairpin cotter (5).
Engaging Transport Bar (Figure 7)
Raise mower with hydraulic cylinder and pivot transport
bar (4) forward over cylinder rod (6). Install lock pin (3)
through hole in transport lock (7) and secure with hair-
pin cotter (2).
