Operating Tips
DANGER
An uncovered discharge opening will allow objects
to be thrown at you or bystanders. Also, contact
with the cutting-unit blades could occur. Thrown
objects or blade contact can cause serious personal
injury.
•
Never operate the machine without the grass
collector or deflector in place.
•
Never place your hands or feet in or near a chute,
blower, or cutting unit.
For the best performance, regulate the traction pedal to keep
the engine speed high and constant. A good rule to follow is
to decrease the ground speed as the load on the cutting blade
increases; and increase the ground speed as the load on the
blade decreases. This allows the engine, which is working
with the transmission, to sense the proper ground speed
while maintaining high blade-tip speed necessary for good
quality-of-cut, vacuuming action, and throwing grass into the
hopper. If the blower speed drops too low, plugging may
result. Refer to the cutting unit and traction units
Operator’s
Manual
for the operation of each.
Important:
Use care to avoid a collision between the
hopper and any stationary objects. Always trim with the
left side of the cutting unit.
•
Inflate all the tires on the traction unit to 124 to 137 kPa
(18 to 20 psi).
•
This grass collector is designed for use in wet or dry
conditions. Do not collect extremely long grass as the
hopper will fill too quickly.
•
When collecting wet, heavy grass, some clippings may not
be thrown completely through the chute. The hole in the
bottom of the chute allows these clippings to drop out
without plugging the chute. When this happens, reduce
the ground speed.
•
The bumper, which protects the blower housing, doesn’t
extend far enough to prevent the chance of the hopper or
hopper frame from striking a stationary object. Stay far
enough away from obstructions to avoid collisions. Trim
with the left side of the cutting unit only.
•
While operating the bagger, check frequently for
excessive clippings left on the turf or uncut grass. If
those conditions occur, the blower or cutting unit may be
plugged. Stop the machine, disengage the PTO, set the
brake, and stop the engine. Check for obstructions in the
chute, blower or cutting unit. Clear any obstruction using
a stick or similar tool. Check the tension on the blower
belt. If the belt is slipping, adjust it.
•
The grass-collector hopper is designed to exhaust air
beside the chute. This allows the hopper to fill completely
without decreasing performance. Grass will fall through
the opening in the front of the hopper when hopper is
full. Immediately disengage the power take off and empty
the hopper.
•
Cut the grass often, especially when the turf growth is
rapid. If you desire shorter turf, cut the grass again.
Overlap the swaths to produce an even cutting pattern.
Important:
When transporting the machine, set
the hopper in the down position with the rear cover
latched over the large cover.
Removing the Hopper and
Frame
1.
Stop the machine, disengage the PTO, set the brake,
and stop the engine.
2.
Move the hopper-control-valve lever forward and
reverse a few times to release the pressure in the
hydraulic system.
3.
Disconnect the quick couplers on the hydraulic line.
4.
Remove the 2 hairpin cotters securing the tie rods to
the frame.
5.
Remove the 2 welded mounting pins and hairpin
cotters securing the hopper to the frame.
6.
Remove the hopper from the frame.
7.
Disconnect the wire harness from the switch on the
hopper frame or seat and remove it from the traction
unit.
Note:
Keep the harness with the hopper.
Note:
The hopper frame is heavy. Support the frame
when removing it or have a helper assist you.
8.
Remove the disconnect pin securing the rear of the
frame to the machine.
9.
Slide the frame off the machine.
10.
To prevent the contamination of the hydraulic lines,
connect the hopper lines together.
11.
Insert the dust caps over the hydraulic fittings on the
machine.
