Section 2 Operating Instructions
Transporting
!
CAUTION!
To prevent personal injury caused by thrown objects, the use of
front & rear safety guards is strongly recommended! To avoid
injury or death from entanglement in rotating drivelines, the
drive gearbox shields must be in place and secure when operat-
ing.
!
CAUTION!
When traveling on public roads at night or during the day, use
accessory lights and devices for adequate warning to opera-
tor’s of other vehicles. Comply with all federal, state and local
laws.
NOTE: Always disengage the tractor’s PTO before
raising the cutter to transport position.
!
DANGER!
Rotary cutters have the ability to discharge objects at high
speeds; therefore, the use of front safety shields is strongly rec-
ommended when cutting along highways or in an area where
people may be present.
1. When raising the cutter to the transport position be
sure that driveline does not contact tractor or cutter.
2. Be sure to reduce tractor ground speed when turning;
and, leave enough clearance so the cutter does not
contact obstacles such as buildings, trees or fences.
Cutting Instructions
1. Your cutter is equipped with free swinging cutting
blades to reduce shock loads to the cutter if striking
obstacles.
3. Select a safe ground speed when transporting from
one area to another. When traveling on roadways,
transport in such a way that faster moving vehicles
may pass you safely.
2. Start the machine slowly; do not use full throttle. Allow
10 seconds for cutter blades to become aligned prop-
erly before going to full power.
4. When traveling over rough or hilly terrain, shift tractor
to a lower gear.
3. The ground speed depends on two things; the density
of the material to be cut, and the size of the tractor.
Never run fast enough to overload the tractor.
Operating Check List
4. It is important to maintain 540 RPM PTO speed. Loss
of PTO speed will allow the blades to hinge back and
result in ragged, uneven cutting.
In addition to design and configuration of equipment; haz-
ard control and accident prevention are dependent upon
the awareness, concern, prudence and proper training in-
volved in their operation, transport, maintenance and stor-
age of equipment. Before beginning to cut the following
inspection should be performed.
5. This cutter was designed to cut grass and light brush
in right-of-ways, pastures and for shredding row crop
residues.

channels. Use the tractors 3-point hydraulic control to
level the cutter deck from front to rear.
There are 4 primary adjustments that should be made pri-
or to actual field operations:
4. With cutter in cutting position, adjust tractor lop link
until upper hitch pin is aligned vertically with lower
hitch pins, see Figure 3-2. Position "A" is for standard
category hitch tractors and position "B" is for smaller
horsepower rated tractors without adequate ground
clearance when cutter is raised for transport.
a. Deck level from left to right
b. Tractor top link length
c. Tractor lower link height
d. Tailwheel height
Proper adjustment of each of these items will provide for
higher efficiency, improved cutting performance and long-
er blade life. The following tools will be needed:
a. Pliable tape measure
b. Spirit or carpenters level
c. Open end or hex end wrench or socket set
d. Protective gloves
Having completed 3-Point Tractor Hookup in the “Assem-
bly and Setup” section on page 10 locate the tractor on a
flat level surface.
1. Use the tractor’s hydraulic 3-point control to lower the
cutter until the tailwheel contacts ground surface.
2. Place a spirit level or other suitable leveling device on
the front of the cutter deck as shown in Figure 3-1. Ad-
just either one or both of the tractors lower link height
adjustments to level the deck from left to right. Some
tractors have only a single adjusting crank.

Section 3 Adjustments
c. Adjust the tailwheel up or down to the desired cut-
ting height and replace the attaching hardware.
!
DANGER!
d. Lower the 3-point hitch and repeat steps 3 and 4
to be sure the deck is level and the top link is ad-
justed properly.
Engage parking brake, disengage PTO, shut off tractor and re-
move key before proceeding. Ensure that all moving parts have
come to a complete stop before dismounting from the tractor.
!
CAUTION!
Wear a pair of gloves when performing this operation. Go to the
back of the cutter and carefully rotate each blade to the position
shown in Figure 3-1. Avoid direct contact with the cutting edge
of the blade.
5. Measure the distance from the end (cutting tip) of the
blade to the ground surface. This distance is the nom-
inal cutting height, see Figure 3-3.
14223
Height Adjustment
Figure 3-4
7. Re-adjust the tractors 3-point hydraulic control such
that the front of the cutter is 1" lower than the rear.
14253
Nominal Cutting Height
Figure 3-3
NOTE: This adjustment is very important. With the
deck positioned at this attitude, the blades will be
cutting material only at the front of the cutter. If the
deck is level, or the rear of the cutter is lower than
the front, the blades are subject to continuous mate-
rial flow which results in additional blade wear and
horsepower loss as well as more frequent blade
sharpening. Refer to Figure 3-5.
Refer to Figure 3-4:
6. If the cutting height is too high or too low, the tailwheel
must be adjusted as follows:
a. Use the tractors 3-point hydraulic control to lift the
cutter such that the tailwheel clears the ground
surface.
b. Remove attaching hardware; bolt (#1), nut (#2),
and lock washer (#3).

Maintenance
Proper servicing and adjustment is the key to the long life
of any farm implement. With careful and systematic in-
spection, you can avoid costly maintenance, time and re-
pair.
After using your cutter for several hours, check all bolts to
be sure they are tight.
Replace any worn, damaged or illegible safety decals by
obtaining new decals from your Land Pride Dealer.

Service Cutting Blades
1. Both blades should be sharpened at the same angle
as the original cutting edge and must be replaced or
reground at the same time to maintain proper balance
in the cutting unit.
Prior to initial operation and after long periods of inactivity,
the Friction Clutch should be "run-in".
a. Tighten all 4 nuts uniformly until the spring load is
low enough that the clutch slips freely with the
PTO engaged.
NOTE: Care should be taken in order not to remove
any more material than necessary when sharpening
blades.
b. Turn nuts fully back. Clutch is ready for use.
!
CAUTION!
2. Both blades should weigh the same after sharpening.
Engage parking brake, disengage PTO, shut off tractor, and re-
move key before making any of the following adjustments.
3. When replacing or sharpening the cutter blades, ex-
amine bolts for excessive wear and replace if neces-
sary. To replace blades:
Eurocardan Clutch Run-In
Refer to Figure 5-2:
a. Order blade bolt Land Pride part # 802-277C.
b. Blade shim (#30), must be installed to insure a
tight and proper fit between the blade bolt and
blade. Too tight a fit may cause blade to not swing
back into proper cutting position after striking ob-
stacles. Too loose a fit will cause play between
blade bolt and blade resulting in excessive wear
on blade carrier, blade bolts and blades. Three
sizes of shims are available: 16 ga., part no. 312-
075D; 18 ga., part no. 312-082D; & 20 ga., part
no. 312-089D.
1. Using a pencil or other marker, scribe a line across the
exposed edges of the clutch plates and friction disks.
c. Torque blade bolt lock nut to 450 ft. pounds. Use a
3’ long pipe to achieve proper torque.
4. If replacing dishpan, nut on gearbox output shaft
should be torqued to 450 foot/pounds and cotter pin
installed in nut with legs securely bent around nut.
Shearbolt Driveline
Cutter drive components are protected from shock loads
by a 1/2" shear bolt. If shear bolt fails, replace with a 1/2"
x 3 1/2" long hex bolt, grade 2. Shear bolt failure can be
avoided by engaging the PTO slowly at low engine rpm.
Clutch
Figure 5-2

2. Carefully loosen each of the 8 spring retainer nuts on
the clutch housing a total of EXACTLY 2 revolutions. It
will be necessary to hold the hex end of the retainer
bolt in order to count the exact number of revolutions.
Walterscheid Slip Clutch Run-In
Refer to Figure 5-1:
3. Start the tractor and engage the PTO drive for 2-3 sec-
onds to permit slippage of the clutch surfaces. Disen-
gage the PTO, then re-engage a second time for 2-3
seconds. Disengage the PTO, shut off tractor and re-
move key. Wait for all components to stop before dis-
mounting from tractor.
RC15 and RC25 Rotary Cutters drive components are
protected from shock loads by a two plate slip clutch and
the RC35 Rotary Cutters are protected by a four plate slip
clutch. The clutch should slip during operation to protect
the cutter from excessive loads.

4. Inspect the clutch and ensure that the scribed mark-
ings made on the clutch plates have changed position.
If any two marks on a friction disk and plate are still
aligned, such indicates that slippage has not occurred
and the clutch must be disassembled to separate the
friction disks, see "Clutch Assembly and Disassem-
bly", on page 18.
Install new friction discs if needed and reassemble all com-
ponents in proper order. Progressively tighten each spring
retainer bolt until the spring length is 1.010 inches,
Figure 5-4.
5. Tighten each of the 8 spring retainer nuts on the clutch
housing EXACTLY 2 revolutions to restore the original
clutch setting pressure.
6. The clutch should be checked during the first hour of
cutting and periodically each week. An additional set
of scribe marks can be added to check for slippage.
See "Clutch Assembly and Disassembly", on page
18, to adjust for proper spring length.
Eurocardan Clutch Assembly &
Disassembly
13741
If the clutch run-in procedure, see "Clutch Run-In" on
page 17, indicated that one or more of the friction disks did
not slip, the clutch must be disassembled to separate the
friction discs. Refer to the Parts Section of this manual for a
detailed parts breakdown.
Clutch Adjustment
Figure 5-4
Storage
At the end of the working season or when the cutter will not
be used for a long period, it is good practice to clean off
any dirt or grease that may have accumulated on the cut-
ter and any of the moving parts.
Refer to Figure 5-3:
Disassembly of the clutch is simply a matter of first remov-
ing the spring retainer nuts (#1), springs (#2) and bolts
(#3) from the assembly. Each friction disc (#4) must then
be separated from the metal surface adjacent to it. Inspect
all parts for excessive wear and condition. Clean all parts
that do not require replacement.
1. Clean the cutter as necessary.
2. Check the blades for wear and replace if necessary.
3. Inspect the cutter for loose, damaged or worn parts
and adjust or replace as needed.
4. Lubricate as noted in Lubrication, starting on page 21.
5. Store the cutter inside if possible for longer cutter life.
6. Repaint parts where paint is worn or scratched to pre-
vent rust. Ask your dealer for Aerosol Land Pride
Beige touch-up paint #821-011C.
Clutch Disassembly
14714
Figure 5-3
The original friction disc thickness is 1/8" (3.2mm) and
should be replaced if the thickness falls below 3/64"
(1.1mm). If the clutches have been slipped to the point of
"smoking", the friction discs may be damaged and should
be replaced. Heat build-up may also affect the yoke joints.
