1. When raising the cutter to the transport position be
sure that driveline does not contact tractor or cutter.
2. Be suretoreducetractorgroundspeed when turning;
and, leave enough clearance so the cutter does not
contact obstacles such as buildings, trees or fences.
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.
4. When traveling overrough or hilly terrain, shift tractor
to a lower gear.
Operating Check List
In addition to design and configuration of equipment; hazard control and accident prevention are dependent upon
the awareness, concern, prudence and proper training involvedin their operation, transport,maintenance andstorage of equipment. Before beginning to cut the following
inspection should be performed.

DANGER!
Rotary cutters have the ability to discharge objects at high
speeds; therefore, the use of front safety shields is strongly recommended when cutting along highways or in an area where
people may be present.
Cutting Instructions
1. Your cutter is equipped with free swinging cutting
blades to reduce shock loads to the cutter if striking
obstacles.
2. Start the machineslowly;do not use fullthrottle.Allow
10 seconds for cutter blades to become aligned properly before going to full power.
3. Thegroundspeed depends on two things;thedensity
of the material to be cut, and the size of the tractor.
Neverrun fast enough to overload the tractor.
4. It is important to maintain 540 RPM PTOspeed. Loss
of PTO speed will allow the blades to hinge back and
result in ragged, uneven cutting.
5. This cutter was designed to cut grass and light brush
in right-of-ways, pastures and for shredding row crop
residues.
!
CAUTION!
Damage may occur if exceeding the cutting capacity of the cutter!
!
CAUTION!
Do not over speed PTO or machine damage may result. This
cutter is designed to be used only with a tractor having a 540
RPM rear PTO.

Section 3 Adjustments
Section 3 Adjustments
Table of Contents
Cutting Height
There are 4 primary adjustments that should be made prior to actual field operations:
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,improvedcutting performance and longer 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
Havingcompleted 3-PointTractorHookup in the “Assem-blyandSetup” section on page 10 locate the tractor on a
flat level surface.
1. Use the tractor’shydraulic3-pointcontrol 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. Adjust 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.
3. Similarly, place a level on either of the main deck
channels.Use the tractors3-point hydrauliccontrol to
levelthe cutter deck from front to rear.
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.

come to a complete stop before dismounting from the tractor.
!
CAUTION!
Wear a pairof gloves whenperforming this operation.Go to the
backof the cutter andcarefully rotateeach bladeto the position
shown in Figure3-1. 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 nominal cutting height, see Figure 3-3.
Land Pride
c. Adjust the tailwheel up or down to the desired cut-
ting height and replace the attaching hardware.
d. Lower the 3-point hitch and repeat steps 3 and 4
to be sure the deck is level and the top link is adjusted properly.

a. Usethetractors3-point hydrauliccontroltolift the
cutter such that the tailwheel clears the ground
surface.
b. Remove attaching hardware; bolt (#1), nut (#2),
and lock washer (#3).
7. Re-adjust the tractors 3-point hydraulic control such
that the front of the cutter is 1" lower than the rear.
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 material flow which results in additional blade wear and
horsepower loss as well as more frequent blade
sharpening. Refer to Figure 3-5.

Section 5 Maintenance and Lubrication
Maintenance
Proper servicing and adjustment is the key to the long life
of any farm implement. With careful and systematic inspection, you can avoid costly maintenance, time and repair.
After using your cutter forseveral 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
regroundatthe same time to maintainproperbalance
in the cutting unit.
NOTE: Care should be taken in order not to remove
any more material than necessarywhensharpening
blades.
2. Both blades should weigh the same after sharpening.
3. When replacing or sharpening the cutter blades, examine bolts for excessive wear and replace if necessary. To replace blades:
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.Tootight a fit may cause bladetonotswing
back into proper cutting position after striking obstacles. Too loose a fit will cause play between
blade bolt and blade resulting in excessivewear
on blade carrier, blade bolts and blades. Three
sizes of shims are available:16 ga., part no. 312075D; 18 ga., part no. 312-082D; & 20 ga., part
no. 312-089D.
c. Torquebladeboltlock nutto450 ft. pounds.Usea

Prior to initialoperationandafter long periods of inactivity,
the Friction Clutch should be "run-in".
a. Tighten all 4 nuts uniformlyuntilthespring load is
low enough that the clutch slips freely with the
PTO engaged.
b. Turn nuts fully back. Clutch is ready for use.
!
CAUTION!
Engage parking brake, disengage PTO, shut off tractor, and remove key before making any of the following adjustments.

Refer to Figure 5-2:
1. Using a pencil or other marker,scribe a line across the
exposed edges of the clutch plates and friction disks.
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.

Refer to Figure 5-1:
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 byafourplate slip
clutch. The clutch should slip during operation to protect
the cutter from excessive loads.

2. Carefully loosen each of the 8 spring retainer nuts on
theclutchhousinga total of EXACTLY2revolutions. It
will be necessary to hold the hex end of the retainer
bolt in order to count the exact number of revolutions.
3. Start the tractorandengage the PTOdrivefor2-3 seconds to permit slippage of the clutch surfaces. Disengage the PTO, then re-engage a second time for 2-3
seconds. Disengage the PTO, shut off tractor and remove key. Wait for all components to stop before dismounting from tractor.

4. Inspect the clutch and ensure that the scribed markingsmade ontheclutch plateshavechangedposition.
If any two marks on a friction disk and plate are still
aligned,suchindicates that slippagehasnot occurred
and the clutch must be disassembled to separate the
friction disks, see "Clutch Assembly and Disassem-bly", on page 18.
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.

Disassembly
If the clutch run-inprocedure, 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.Referto the Parts Section of this manual fora
detailed partsbreakdown.
Refer to Figure 5-3:
Disassemblyoftheclutch is simply a matter of first removing the spring retainer nuts (#1), springs (#2) and bolts
(#3) from the assembly.Each friction disc (#4) must then
beseparatedfrom the metalsurfaceadjacenttoit.Inspect
all partsforexcessive wear and condition. Clean all parts
that do not require replacement.
Install newfrictiondiscsifneededandreassembleall components in proper order. Progressively tighten each spring
retainer bolt until the spring length is 1.010 inches,

Storage
Atthe endofthe workingseasonor whenthe cutterwillnot
be used for a long period, it is good practice to clean off
any dirt or grease that may have accumulated on the cutter and any of the moving parts.
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 inLubrication, 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.

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 maybe damaged and should
be replaced. Heatbuild-upmay also affect theyokejoints.
