Operation
Note:
Determine the left and right sides of the machine
from the normal operating position.
Before Operating Hopper
1.
Start the engine. Raise and lower the hopper several
times. Move the control valve lever forward to lower
the hopper and in reverse direction to raise the hopper)
2.
Check the interlock switch operation as follows:
•
Raise the hopper and engage the PTO switch while the
engine is running. The engine should stop within 2
seconds. If the engine stops, the switch is operating
correctly; thus, proceed to next step. If the engine does
not stop, there is a malfunction in the interlock system.
•
Raise the hopper and depress the traction pedal while
the engine is running and the PTO lever is disengaged.
The engine should stop within 2 seconds. If the engine
stops, the switch is operating correctly; thus, continue
operation. If the engine does not stop, there is a
malfunction in the interlock system.
3.
Stop the engine. Check for hydraulic leaks. Check the
hydraulic fluid level in the front axle and replenish it as
necessary. (Refer to the Traction Unit Operator’s
Manual for specifications).
Hopper Operation
(When used with a 52” or 60” Blower Kit)
1.
Move the control valve lever forward to lower the
hopper and in the reverse direction to raise the hopper.
Operating Characteristics
When the grass collector is removed, NEVER
operate without the deflector in place.
Caution
For the best performance, regulate the traction pedal to
keep engine rpm high and somewhat constant. A good rule
to follow is: 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,
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 to throw grass
into the hopper. If the blower speed drops too low, plugging
may result. Refer to the Cutting Unit and Traction Unit
Operator’s Manual for operation of each.
Use care to avoid a collision between the
hopper and any stationary objects. Always
trim with the left side of the cutting unit.
Caution
1.
Inflate all the tires on the traction unit to 18–20 psi.
2.
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.
3.
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 ground speed.
Never place hands or feet in chute, blower, or
cutting unit.
Caution
4.
The bumper which protects the blower housing doesn’t
extend far enough to eliminate the chance of the hopper
or hopper frame striking a stationary object. Stay far
enough away from obstructions to avoid collisions.
Trim with the left side of the cutting unit only.
5.
While operating, 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 unit, disengage the PTO, set the brake
and shut off the ignition. Check for obstructions in the
chute, blower or cutting unit. Clear any obstruction
using a stick or similar tool. Check blower belt tension.
If slipping, readjust.
6.
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.
7.
Cut the grass often, especially when the turf growth is
rapid. If shorter turf is desired, cut the grass again.
Overlap the swaths to produce an even cutting pattern.
Important
When transporting, hopper must be in down
position with rear cover latched over large cover.
