2. Then go to the regular service schedule
as defined on page 15
Pre-Operation Checklist
Efficient and safe operation of the Rotary
Cutter requires that each operator reads and
understands the operating procedures and all
related safety precautions outline in this
section. A pre-operation checklist is
provided for the operator. It is important for
both the personal safety and maintaining the
good mechanical condition of the Cutter that
this checklist is followed.

checked off:
1. Lubricate the machine per the schedule
outlined in the Service and Maintenance
section on page 15.
2. Check that the machine is properly
attached to the tractor. Be sure retainers are
used on the mounting pins.
3. Check the oil level in the gearbox. Add as
required.
4. Check that the PTO driveline turns freely
and that the driveline can telescope easily
5. Check the blades. Be sure they are not
damaged or broken and swing freely on their
mount. Inspect for wear. Repair or replace
as required.
6. Check for entangled material in all
rotating parts. Remove this material.
7. Install and secure all guards, doors and
covers before starting.

Equipment Matching
To insure the safe and reliable operation of
the Cutter, it is necessary to use a tractor
with the correct specifications. Use the
following list as a guide in selecting a tractor
to use on the machine.
1. Horsepower
Use Table 1 as a guide in selecting the
tractor horsepower appropriate for your
width of machine.
Increase the power level by 25% when
operating in hilly, soft or wet conditions.
2. Tire Configuration
It is recommended that the tires be set so the
machine always covers the tracks. In this
way the machine will always cut where the
tractor has driven.
3. 3 Point Hitch
The Cutter is equipped with Category 1&2
Quick Hitch and Cat 1and 2 free link.
Install the lift arm blocks or shorten the stop
chains to place the arms into the non-sway
configuration. Refer to the tractor manual
for details.
4. Load Sensing Hydraulics (3 point
models only)
Many newer tractors are equipped with
"Load Sensing" hydraulics. It is the
responsibility or the operator to set the
tractor hydraulic system to provide "float"
on the 3 point hitch. Refer to the tractor
manual. The float feature will allow the
machine to follow the ground contours
during operation.
Table 1 : Horsepower vs Width
5. PTO Shaft:
The tractor must have a 1 3/8 inch 6 spline
540 RPM PTO shaft to fit driveline shaft
supplied with the machine. Do not use shaft
adaptors or operate at any other speed.
Model Width Horsepower
40" 3.3 feet 20
(1m)
48" 4 feet 25
(1.3m)
60" 5 feet 30
(1.5m)
72" 6 feet 35
(1.8)
84" 7 feet 40
(2.1m)

Driveline dimension
A PTO driveline is supplied with the
machine. To accommodate the variety of 3
point hitch geometry available today, the
driveline can be too long for some machines
and must be cut. It is very important that the
driveline be free to telescope but not bottom
out when going through its working range. If
the driveline bottoms out, the bearings on
the machine and the tractor PTO shaft will
be overloaded and fail in a short time.
When Cutting The Driveline Follow this
procedure:
1. Clear the area of bystanders, especially
small children.
2. Attach the Cutter to the tractor (see next
page, Attaching/Unhooking) but do not
attach the driveline
3. Raise the machine until the input shaft is
level with the tractor PTO shaft.
4. Measure the dimension the locking
groove on the tractor PTO shaft to the
groove of the Cutter input shaft.
5. Measure the same points on the
compressed driveline. (pin to pin)
6. If the compressed driveline dimension
exceeds the machine dimension, the
driveline will have to be cut.
7. Pull the driveline apart and cut 1/2 of the
dimension determined in step 5, plus 1/2"
from each end.
8. Be sure to use a hacksaw to cut 1/2 from
each end of the separated shaft. Cut both the
plastic tube and the metal cores.
9. Use a file to remove burrs from the edges
that were cut.
10. Assemble the two ends of the shaft
11. Make sure that the shaft can telescope
freely. If it does not, separate the two parts
and inspect for burrs or cuttings on the shaft
ends, be sure it telescopes freely before
installing.
12. Make sure the plastic covering shield is
free to rotate on the shaft before installing
on the machine.
9

Attaching / Unhooking
The Cutter should always be located on a
level, dry area that is free of debris and other
foreign objects. When attaching the machine
to a tractor, follow this procedure.
1. Clear the area of bystanders, especially
small children.
2. Be sure the tractor 3 point hitch is in the
Category 1 configuration and the lift arms
are in the non-sway configuration (see
tractor manual)
3. Make sure there is enough room and
clearance to safely backup to the machine.
4. Attach the PTO driveline to the Cutter if it
was removed for storage (See Assembly)
5. While backing up, align the lift arm balls
with the mounting pins on the Cutter.
Note
It may be necessary to add weight to
the 3 point hitch to lower the lift
arms.
6. Stop tractor, set park brake, remove
ignition key and wait for all moving parts to
stop before dismounting.
7. Align the left lower link arm with the
mounting pin.
8. Slide the ball over the pin and install the
retainer
9. Use the screw jack on the lift arm to align
the ball with the pin.
10. Slide the ball over the mounting pin and
install the retainer
11. Level the frame, using the screw jack.
12. Remove retainer and pin from the mast
top.
13. Align top link using the turnbuckle
14. Insert pin and install retainer.
15. Set the mast using the turnbuckle and
leave slack in the chain.
16. Attach the PTO driveline:
a. Check that the driveline does not bottom
out when going through working angles.
(Refer to page 9)
b. Attach the driveline to the tractor by
retracting the locking pin, slide the yoke
over the shaft and push on the yoke until the
lock pin clicks into position. Pull on the
yoke to be sure it is locked in position.
c. Attach the anchor chain on the driveline
shield to the frame.
17. Use the 3 point hitch to raise the
machine
18. Reverse the above procedure when
unhooking from the tractor.
10

Set the Machine:
a. Level the frame:
i. Use the screw jack on the right lift arm to
level the frame from side to side.
ii. Use the turnbuckle on the top link to
leave slack in the chain. This will allow the
machine to follow the contour of the ground.
iii. Set the 3 point hitch so deck is the same
distance in the front and back.
b. Height
Use the adjustment on the trailing wheel to
set the height of the deck.
Use lower hole for longer cutting and upper
hole for shorter cutting.
Align the unit with the working
area

--------------------------------------
Place all controls in neutral, lower
machine, stop the engine, set park
brake, remove ignition key and wait
for all moving parts to stop before
dismounting
11

Ground Speed:
Travel speed can vary between 1 and 4 mph
(1.5 and 6 km/h) depending on the grass and
terrain conditions. It is the responsibility of
the operator to note the condition of the job
being done and set the speed to obtain a
quality cutting job and maintain control of
the machine.
The speed can be increased if a good job is
being done.
Decrease the speed it you are producing a
ragged cut or leaving patches uncut.
Operating Hints:
a. although it is best to cut when it is dry, the
Mower works in wet conditions as well.
However the operator will have to travel
slower to do the same quality cutting. It will
also be necessary to clean the machine more
frequently to prevent caking and clogging of
the blade area.
b. The cutter should always be operated at
the rated speed of 540 RPM. The cutting
action is generated by the speed of the blade
tip. When the speed drops below a certain
rate (slowing of the input speed or RPM),
the blades start to tear the material rather
than cut it and will give a "ragged" looking
cut.
c. Vary ground speed by changing gears in
the tractor transmission rather then
changing the throttle setting. Forward travel
speeds can range from 1 to 4 mph (1.5 to 6
km/h), depending on the terrain, grass or
length, moisture level. It is the operator's
responsibility to determine and operate the
machine at a safe speed at all times.
d. If the grass is tall, cut it twice to obtain
the best results. This allows the unit to cut
less material on each pass.
e. When mowing a new area for the first
time, always set the cutter to cut high to
clear unknown obstructions, if none are
found, the cutter can be set lower for the
second pass.
f. Never cut grass shorter than recommended
for your weather conditions. short grass is
less able to with stand hot and dry
conditions. It is better to cut more frequently
at a longer length than to cut too short.
g. The blades will need sharpening when
you see that the grass has not been cut
evenly or it looks like the grass has been
ripped off.
h. always reduce ground speed when cutting
around obstructions or close quarters.
i. The mower should always be operated
with its wheels riding on the ground and not
normally lifted for turns or corners. If lifted
it should be dropped back on the ground as
soon as the maneuvering is done..
j. The Mower has three blades under the
frame that are turning at a high rate of speed.
With this speed the blades can pick up
objects on the ground and expel them out
under the frame or out the discharge areas. It
is extremely important the operator be aware
that objects can be expelled this way and
never point the discharge areas toward
people, animals or property. These expelled
objects are moving fast enough to damage
property. It is better to stop cutting when
there are bystanders especially children, than
to take the chance of injury.
Caution
----------------------------
Never exceed PTO speed of
540 RPM!
