Cutting Instructions
!
CAUTION
Do not over speed PTO or machine damage may result. This
cutter is designed tobe used only with a tractor having a 540
RPM rear PTO.
!
WARNING
The RCR186 series cutter is designed to cut grass and brush
up to 1 1/2” in diameter. Using this cutter for another type of
work can damage the drive components, deck and support
frame.
!
DANGER
Gearbox and driveline shields must be secured in place when
operating to avoid injury or death from entanglement in
rotating drivelines.
!
DANGER
Rotary Cutters have the ability to discharge objects at high
speeds. Therefore, the use of front & rear deck safety shields
is strongly recommended when cutting along highways or in
an area where people may be present!
!
DANGER
Never operate the cutter in theraised position. The cutter can
discharge object at high speeds resulting in serious injury or
death.
!
DANGER
Do not cut on steep inclines. The tractor and cutter could flip
over causing damage to the equipment, serious bodily injury
or death.
!
DANGER
Do not use cutter to lift or carry objects. Lifting and/or
carrying objects can result in damage to the cutter, serious
bodily injury or death.
!
DANGER
Never carry a person on the cutter. A person can fall and be
ran over by the cutter or tractor causing serious injury or
death.
!
DANGER
Do not use deck as a working platform. The deck is not
properly designed or guarded for this use. Using deck as a
working platform can cause serious injury or death.
!
DANGER
Do not use deck as a fan. Cutting blades are not properly
designed or guarded for this use. Using the deck as a fan can
result in injury and/or death.
NOTE: Your Rotary Cutter is equipped with free
swinging cuttingblades to reduce shock loads to the
cutter if striking obstacles.
IMPORTANT: It isimportant tomaintain correct RPM
PTO speed. Loss ofPTO speed will allow the blades
to hinge back and result in ragged, uneven cutting.
This cutter was designed tocutgrassand medium brush
in right-of-ways, pastures and for shredding row crop
residues.
1. Thoroughly Inspect the area to be cut for debris and
unforeseen objects. Mark any potential hazards.
2. Start the machine slowly; do not use full throttle.
Allow 10 seconds for cutter blades to become
aligned proper ly before going to 540 RPM.
3. Neverrun fastenough tooverload thetractor orcutter.
Ground speed depends on two things:
• The density of material being cut.
• The size of tractoroperating the cutter.
4. After the first 50 feet, stop and check to seethat the
cutter is adjusted properly.
5. Do not engage PTO with machine in the fully raised
or lowered position.
6. Periodically disengage PTO, turn off tractor, remove
ignition key and check for foreign objects wrapped
around the rotor shaft. Block cutter deck up before
removing objects.
General Operating Instructions
It is important that you familiarized yourself with the
Operator’s Manual, completed Operators Checklist,
properly attached cutter to your tractor, made leveling
adjustments, and preset your cutting height before
beginning a running operational safety check on your
Land Pride 84" Rotary Cutter.
The running operational safety check maynow be done.
It is important that at any time during this safety check
youdetect a malfunctionin either thecutter or tractorthat
you immediately shut the tractor off, remove its’ key, and
make necessary repairs and/or adjustments before
continuing on.
Make sure before startingthe tractorthat the park brake
is engaged, the PTO is disengaged, and the cutter is
restingon theground.Start thetractor and setthe engine
throttle speed at a low idle. Raise the cutter with the
tractor’s rear hydraulic lift control lever to transport

position making sure that the PTO shaft does not bind
anddoes notcontactthe cutterframe. Lower thecutter to
the ground and at a low engine speed engage the PTO.
If everything is running smoothly at a low idle, slowly
raise the cutter to transport height checking for bind or
chatter in the driveline. Lower the cutter to the ground
and increase the tractor’s engine rpm until itreaches the
cutter full PTO operating speed of 540rpm. If everything
is still running smoothly, once more raise the cutter to
transport height to check for driveline bindor chatter.
Lower the cuttertotheground, return the engine to a low
idle, and disengage the PTO. Position theadjustable
stops on the tractor’s hydraulic lift lever so the cuttercan
be consistently returned to the same cutting and
transport height.
You should now be ready to transport to your cutting site
at a safe ground speed. On roadways transport insuch
a manner that faster movingvehicles can easilysee you
and passyousafely.Reduce your speed when travelling
overrough and hillyterrain. Avoidquickor sharpsteering
corrections. Take extra care to insure thatthe mower
doesn’t come into contact with obstacles such as trees,
buildings or fences. Use accessory lights and
appropriate reflective devices to provide adequate
warningto pedestrians andother vehicle operatorswhen
travelingonpublic roads and in thedark of night. Comply
with all local, state and federal laws.
It isimportantthatyou inspect the area where you will be
cutting and clear itof safetyhazards andforeign objects
either before or afteryou arriveat thecutting site. Never
assume the area is clear. Cut only in areas you are
familiar with and are free of debris and unseen objects.
Extremely tall grass should be cut twice to detect
potential hazards. In the event you do strike an object
stop the cutter and tractor immediately toinspect and
make necessary repairs to the cutter before resuming
operation. It really pays to inspect a new area and to
develop a safe plan before cutting.
You will need to maintain 540 rpm PTOspeed and 2 to 5
mphground speed toproduce a cleancut. Make atractor
gear and range selection that will enable you to maintain
these speedcombinations. Generally the quality of cut is
better at lower ground speeds. Dense ground cover will
create the need to slow down even more. In certain
conditions tractor tires will roll grass down resulting in an
uneven cut when the grass fails to rebound. Should this
happensyou may try reversingthe direction ofcutand/or
double cut to achieve the desired finish. Avoid very low
cutting heights especially on extremely uneven terrain.
Always cut downward on slopes and avoid crossing the
face of steep slopes. Avoid sharp drops and cross
diagonally throughdipsto prevent hanging up the tractor
and cutter. Slow down in turns. Remember to look back
often.
Nowthat you’re preparedand well briefedyou may begin
cutting. Begin mowing by doing the following:
• Reducing the tractor’s engine rpm
• Make sure the cutter ison the ground incuttingposition
• Engage the PTO
• Raise the engine rpm to the appropriate PTO speed
• Begin mowing.
Make wide turns when possible. Three-point hitch and
optional Quick-Hitch models can be lifted into transport
position to make tight turns and to reverse direction. Try
increasing or decreasing ground speed todetermine the
effect on quality of cut. With a little practice you will be
pleasedwith whatyouand yourLand Pride RotaryCutter
can do.
Whether you aredone mowing, need to take a break, or
just need to make a few adjustments to the cutter,
remember to always do the following:
• Reduce the tractor’s engine rpm
• Disengage the PTO
• Stop on level ground
• Set the park brake
• Turn off the engine and remove the key
• Stay on the tractor until the cutter blades have come to
a complete dead stop.

DANGER
Rotary Cutters have the ability to discharge objects at high
speeds; therefore, use of front and rear safety shields is
strongly recommended when cutting along highways and in
areas where people may be present.
IMPORTANT: Not all objects will be stopped by
safety shields. Therefore, Land Pride recommends
using extreme cautionwhen cutting in public areas.
It is best to operate the Rotary Cutter when no one
is within 300 feet of the cutter.
Land Pride offers two types of front guards to best suit
your application. They are the rubber skirt guard and
chain skirt guard. The rubber skirt guardis more
economical and designed for light duty applications. The
chain guard is designed to handle heavier applications
where cutter blades make contact with solid dense
objects that are capable of tearingthrough rubber skirts.

5. Both blades should be sharpened at the same angle
as the original cutting edge and must be replaced or
re-ground at the same time to maintain proper
balance. The following precautions should be taken
when sharpening blades:
a. Do not remove more material than necessary.
b. Do not heat and pound out a cutting edge.
c. Do notgrind blades to a razor edge. Leave a blunt
cutting edge approximately 1/16” thick.
d. Alwaysgrind cutting edge so end of blade remains
square to cutting edge and not rounded.
e. Do not sharpen back side of blade.
f. Both blades should weigh the sameafter
sharpening with not more than 1 1/2 oz. difference.
Refer to Figure 5-1:
6. Carefully check cutting edges of blades in relation to
blade carrier rotation to ensure correct blade
placement. Blade rotation is counterclockwise with
cutting edge leading. Airfoil (lift) must be oriented
towards the top of the deck.
IMPORTANT: Replace cutting blades with genuine
Land Pride blades only. Blades must be replaced in
mating pairs. Not replacingboth bladeswill resultin
an out-of-balance condition that will contribute to
premature bearing break down on the spindle hub
and create structural cracks in cutter housing.
Always inspect cutting blades before each use. Make
certainthey are properly installedandare in good working
condition.Replace anyblade that isdamaged, worn,bent,
or excessively nicked. Small nicks can be ground out
when sharpening.
1. Place tractorgearselector in park and/or set brakes,
shut engine off and remove ignition key.
2. Disconnect main driveline from tractor PTO and
secure cutter deck in theup position with solid
supports beforeservicing underside of cutter.
3. Inspect cuttingblades. Make certain theyareproperly
installed and are in good working condition. Replace
anyblade that is damaged, worn,bent, or excessively
nicked. Small nicks can be ground out when
sharpened.
4. To remove blades from the cutter, align blade bolts
with blade bolt access holelocated in the deck as
shown in Figure 5-1.

Driveline Protection
Cutter drive components are protected from shock loads
by a friction slip-clutch. The clutch must be capable of
slippage dur ing operation to protect the gearbox,
driveline and other drive train parts.
Clutch Run-In
Friction clutches should be “r un-in” prior to initial
operation and after long periods of inactivity to remove
any oxidation that may have accumulated on friction
surfaces. To prevent driveline and gear box damage,
repeat “run-in” instructions at beginning of each season
and when moisture and/or condensation seizes inner
friction plates.

Refer to Figure 5-4 on page 26:
Disassembly of the clutch is simply amatter of removing
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.
Clutch Inspection
Inspect all parts for excessivewear and condition. Clean
all parts that do not require replacement.The original
friction disc thickness is 1/8" (3.2 mm) and should be
replaced if thickness falls below 3/64" (1.1 mm). If
clutches havebeen slipped to the point of“smoking”, the
friction discs may be damaged and should be replaced.
Heat build-up may also affect yoke joints.
Clutch Assembly
Refer to Figure 5-4:
Reassemble each friction disc (#4) next to the metal
plate it was separated from. Install bolts (#3) through the
end plates and intermediate plates as shown. Place
springs (#2) over the bolts and secure with nuts (#1).
Refer to Figure 5-5:
Install new frictiondiscs ifneeded and reassemble all
components in properorder. Progressivelytighten each
spring retainer nutuntil spring length is 1.283” (1 9/32”).

Cutter Storage
It is good practice to clean off any dirt or grease that may
haveaccumulatedon the cutter and onanymoving parts
at the end ofaworkingseasonor when the cutter will not
be used for a long period.
!
DANGER
Always disconnect main driveline from tractor PTO and secure
cutter deck in the up position with solid supports before
servicing the underside of the cutter.
