Tractor Requirements
The Parallel Arm Cutter, by design, must be used only
on tractors that are capable of controlling the cutter
under all operatingconditions. When the arms are fully
extended, a right-hand torque load on the tractor is
present which will try to tip the tractor over! The tractor
MUST have a minimum weight of 7000 lbs. A 3-Point
Category II or Category III hitch with hydraulic lift
control is required.
As shown in Figure 2-1, the rear wheel base must be
not less than 74" wide asmeasured from the outside of
each tire. If the right-hand tractor tire is more than 47"
from the center of the tractor, it may interfere with the
hydraulic motor on the deck when it is in the transport
position. If the tractor is equipped with dual wheels, the
right-hand dual may have to be removed.
A single, tractor duplex hydraulic outlet is required if
the cutter is equipped with the optional Electric
Cylinder Control. Three duplex hydraulic outlets will be
needed for parallel arm and deck control if the cutter is
NOT equipped with the optional Electric Cylinder
Control.
Anadditionaltractor,duplexhydraulicoutletisrequired
if the cutter is equipped with the optional hydraulic
breakaway cylinder.
A tractor Power Take-Off (PTO) is required for pump/
motoroperation. This cutteris available witheither 540
rpmor 1000 rpm rated PTO speed increasers.For best
fuel economy, it is recommended that the 540 rpm unit
be used on 1000 rpm tractors. However, PTO output
RPM must be carefully controlled (by engine RPM)
such that the PTO speed does not exceed 540 RPM.
The actual horsepower required for pump/motor
operation is approximately 30 HP.
If the tractor weight is less than 8500 lbs, auxiliary
counterbalance weights will be required. These
weights can be added to the weight bracket of the
hydraulic reservoir or (preferably) to the left-hand
tractor wheel.
The reservoir weight bracket is designed to be used
with conventional John Deere type suitcase weights each weight being 100 lbs. A total of 8 weights can be
added to the bracket.
ThetractorMUSTbeequippedwithoperatorprotective
equipment in the form of shielding from thrown objects
andRollOverProtectiveStructure(ROPS)asshownin
Figure 2-1.
A universal operator protective shield is available from
Great Plains Mfg. Refer to page 16 for more
information and installation.
It is also recommended that protective shielding or
screen be added to the right hand side of the tractor
engine cowling and radiator. This will help protect the
tractor finish and radiator against thrown objects.
The lower 3-Point links of the 3-Point hitch must be
stabilized to prevent side-to-side movement. Most
tractors have sway blocks or adjustable chains for this
purpose.

This cutter has been assembled at the factory. Some
preparation will be necessary to attach the cutter to the
customer’s tractor. Ensure that the intended tractor
conforms to the requirements stated under the heading
“Tractor Requirements” on page 9.
IMPORTANT: Hydraulic fluid must be added to the
hydraulic reservoir before this unit is placed into
operation. Do not attempt to run the pump without
fluid or damage to the pump will occur.
3-Point Hookup
Prepare the cutter as follows:
1. Locate the cutter on a flat and level concrete
surface.
2. For proper hitch configuration determine the hitch
category for the tractor being used.
(Refer to Figure 2-2 on page 11)

3. Back the tractor into position and connect the
3-Point hitch ar ms and top link. Start the tractor,
thenslowly raise the 3-Point hitch about 1-2". Stow
the jack stands in the raised position.
Check to be sure that the deck safety chain is in
place.
Slowlyoperate thetractor's3-Pointhydraulic control
up and down and check for clearance between the
tires, reservoir, frame, drawbar etc.
Ensure that the lower arms are blocked to prevent
excessive side movement. Adjust the tractor's
Lower lift arms to level the cutter from left to right.
Adjustthe top-link so thatthecutterisapproximately
level from front to rear. A final adjustment will be
made later.
Before operating this unit, 80-90 EP Gear Lube must be added to the gearbox & motor as indicated in the
maintenance lubrication section (page 27) of this manual.
35 Gallons of Hydraulic Fluid for the hydraulic reservoir. Use any high quality mineral based hydraulic fluid such as
Mobil Fluid 424 with a viscosity rating of 10W-30.
Additional hydraulic fluid (approx 2 gallons) for the tractor reservoir.
Miscellaneous assembly tools: hammer, tape measure, hacksaw, assortment of wrenches and sockets,1/4" drill/drill
bits,
spirit level.
Quick disconnect adaptors to match your tractors duplex outlets. Quantities required depend on options selected:
(2) If equipped with Electric Cylinder Control Option
(6) If not equipped with Electric Switching Option
(2) If equipped with hydraulic Breakaway Cylinder Option
Possible need for forklift or hoist capable of lifting 2500 lbs.
Auxiliary tractor weights (depending on tractor size).
A minimum of two people available during assembly.
If a pin, bolt or other part has been removed, and you are unsure where it is used, use the parts section of this
manual to identify it. Be sure the part gets used in the correct location. By double checking while you assemble, you
will lessen the chance of using a bolt incorrectly that may be needed later.

PTO Hookup
IMPORTANT: Do not engage tractor PTO until
driveline is fully connected and hydraulic fluid has
been added to the cutter reservoir.
IMPORTANT: A quick hitch may be used, but is not
recommended because it moves the cutter deck
back about 5" and impedes operator visibility.
IMPORTANT: See Figure 1-4 below. Avoid
premature PTO dr iveline breakdown. PTO driveline
mustnot exceedanangle of 25 degrees upordown
while operating cutter.

the tractor PTO shaft. Attach inner driveline
universaljoint to the Rotary Cutter gearbox shaft.
Pull on each drivelinesection to be sure universal
joints are secured to the shafts.
d. Hold driveline sections parallel to each other to
determine if theyaretoolong. The inner and outer
shieldsoneach section should end approximately
1" short of reaching the universal joint shield on
the adjacent section (see “B” dimension). If they
are too long, measure 1" (“B” dimension) back
from the universal joint shieldand make a mark at
this location on the inner and outer driveline
shields.
e. Cut off inner shield at mark (“X” dimension). Cut
same amount off inner shaft (“X1” dimension).
Repeat cut off procedure (“Y”&“Y1” dimensions)
to outer driveline half.
f. Remove all burrs and cuttings.

11. Start tractor and raise cutter just enough to remove
support blocks used in step 4a on page 12.
12. Slowly engage tractor’s hydraulic 3-point controls to
raise and lower the cutter. Check drawbar clearance.
Move or remove drawbar as needed.
Hydraulic Hookup
1. Connect the hydraulic hoses to the tractor duplex
outlet(s). “Pioneer” quick disconnect hose couplings
are supplied with each hose. Some tractors use
other types of quick couplers.
a. See Figure 2-4: If the cutter is equipped with the
optional electric cylinder control, two hoses from
the solenoid valve control box will be attached to
a single duplex outlet on the tractor.
See Figure 2-5: You must determine if the tractor
being used is configured for “OPEN” or
“CLOSED” center hydraulic flow. Consult the
tractor operator's manual if unsure. Remove the
access cover located at the rear of the solenoid
valve control box to adjust the flow control valve.
If the tractor is OPEN center, the valve must be
open(turnknob counterclockwise). If the tractor is
CLOSED center, the valve must be closed (turn
knob clockwise).
b. See Figure 2-6: If the cutter is NOTequippedwith
the optional Electric Cylinder Control, six hoses
(2 per cylinder) will be connected to 3 duplex
outlets on your tractor. Each tractor duplex outlet
must be capable of infinite, variable flow control
by the operator and should have center detent
(off) levers. A typical tractor setup is shown in
Figure 2-6. The hoses on each outlet should be
connected such that when the control lever is
pushed“forward”,thearm (or deck)extends.If the
levers operate in reverse, simply reverse the
hoses at the duplex receptacle.

Control Box and connect the circular plastic connector to
the mating connector on the box.
See Figure 2-4 on page 13.Route the power cable to the
tractor battery or circuit breaker panel. A 10 Amp or
larger fuse/circuit breaker source should be used.
Connect the red lead to the positive power source.
Connect the black lead to the negative source.
IMPORTANT: Connect leads to 12VDC power
source only. Connection to 24VDC or larger will
damage electrohydraulic components.
Ensure that the 10 Amp circuit breaker located on the
switch control box is pushed in prior to functional check.
IMPORTANT: This section only applies to Unitswith
Solenoid Control Valve Option.
Determine if tractor is “OPEN” or “CLOSED” Center
HydraulicSystem. If unsure consultyour tractors owners
manual and/or contact your tractor dealer.
IMPORTANT: All dual 6 volt batteries are not
hooked up correctly cylinders may not function
properly due to solenoid valves not being fully
charged. Arm and deck functions will be slow.
See Figure 2-8: Find a suitable location for the Switch
Control Box. Based on our experience, the location
should be close to the right hand side of the operator most generally on the tractor fender or fender console.
Exact location should be convenient to the specific
operator. Orient the Control Box such that the switches
are relative to the movement of the deck and parallel
arms. I.e., when the switch is toggled, the arms or deck
should move in the same relative direction as the handle
of the switch.

Hydraulic fluid under pressure can penetrate skin. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. Use a piece of cardboard or wood
rather than hands when searching for hydraulic leaks. If
hydraulic fluid is injected into the skin, it must be treated by a
doctor within a few hours or gangrene may result.
DANGER
NOTE: The following procedure assumes that the
cutter is equipped with the optional Electric Cylinder
Control. Go to step “c” if your cutter is not equipped
with this option.
a. In Step 1.a. (Hydraulic Hookup), two hoses from
the Solenoid Control Valve were connected to a
single duplex outlet on the tractor. If the tractor is
equipped with more than one remote duplex
outlet, you must first determine which console
lever is used to control this outlet. The control
lever must then be locked into the “Automatic
Extend Position” or the “Automatic Retract
Position”.
b. Toggle the switch on the control box labeled
“ARM1” by pushing it forward (away from you).
The inboard parallel arm should extend outward.
If it does not move, or moves in the opposite
direction (retracts), you should either change the
position of the console lever (from retract to
extend or vice-versa) or reverse the hoses at the
duplex outlet. Toggle the ARM1 switch by pulling
back on it. The inboard parallel arm should
retract. See Figure 2-10.
Repeat this procedure for the remaining arm and
deck cylinders. Cycle all of the cylinders to full
extension and retraction to remove any air that
might be trapped in the system.
Check the hydraulic fluid level in your tractor's
reservoir. If low, add fluid to the system before
proceeding. The cylinders and hoses will require
approximately 1 3/4 gallons from the tractor.
NOTE: Thefollowing procedure is for those cutters
that are not equipped with the Electric Cylinder
Control.
c. Operate the tractor console control lever
designated for “ARM1” by pushing it forward. The
inboard arm should extend outward. If the arm
tries to retract, reverse the hoses at the duplex
outlet. See Figure 2-10.
Repeat this procedure for the remaining arm and
deck cylinders. Cycle all of the cylinders to full
extension and retraction to purge any air that
might be trapped in the system.

Check the hydraulic fluid level in your tractor's
reservoir. If low, add fluid to the system before
proceeding. The cylinders and hoses will require
approximately 1 3/4 gallons from the tractor.
d. Move the tractor and cutter to a remote location
(awayfrom all other persons) to check pump/
motor operation. Check to be sure the Hydraulic
Reservoir shut-off valve is full OPEN. If this
service valve is turned off, damage will occur to
the pump.
Position the cutter deck flat on the ground or
concrete surface. SLOWLY engage the PTO to
start blade rotation. On initial start-up, blade
position may cause the deck to “vibrate”. After 23 revolutions, these vibrations should stop. If the
deck continues to vibrate, shut off the PTO, raise
the deck and check for locked blades.
Gradually increase engine RPM until PTO output
RPM is 540. The deck should not exhibit
excessive vibration.
IMPORTANT: If the tractor being used is equipped
with a 1000 RPM PTO output, be sure that throttle
RPM is reduced to limit PTO output to 540 RPM.
Carefullyremove the shieldfrom the shipping carton and
temporarily position it on the inside surface of the ROPS
bar. Locate the shield forward/back, up/down to provide
the best overall coverage for the tractor operator. Use a
spirit level to level the shield before marking. Mark the
top frame location with a pencil on each side of the
ROPS bar, and mark the vertical ROPS location on the
frame of the shield.
Position the shield (#5) on a flat work surface. Locate
one of the 316-116D (#4) flatbars next to the pencil
marks to determine which set of holes will clear the
vertical marks for the ROPS location. Mark the hole
location and drill two 1/4" diameter holes through the
frameofthe shield. Similarly mark and drilltwoadditional
holes for the lower clamp location.
Attach the shield to the inside surface of the ROPS bar
using the mounting hardware provided (#1), (#2), (#3),
and (#6).
Operator Protective Shield
Anoptional operator protective shieldis available for use
on tractors not equipped with cabs or other protective
shielding. This shield isa "universal" type andis suitable
for attachment to a conventional Roll Over Protective
Structure (ROPS) bar that is already attached to the
tractor. The shield is constructed of an extruded
aluminum frame and is glazed with 1/4" clear, lexan
polycarbonate.
Mounting hardware will permit attachment to ROPS
having cross-section dimensions of 2" x 4", 2" x 5", and
2" x 6" or 2 1/2" x 4", 2 1/2" x5 and 2 1/2" x6. Other sizes
may require longer mounting bolts and/or custom
flatbars. Installation requires that 4 mounting holes be
drilled in the frame of theshield. No modification is made
to the ROPS.
Installation
Refer to Figure 2-11:
Measurethe width andthickness of the ROPS bar on the
tractorto determine that theclamping hardware supplied
will be adequate.
Compare the parts list on and quantities with the parts
received. Report any missing or damaged items to your
dealer.
To determine the best location for the shield, the cutter
should be connected to the tractor. The parallel arms
should be fully extended and the deck should be
horizontal (or approximately level).

Setting Flow Control Valve
This procedure is for those units with the solenoid valve
option, on RCP 2560 and RCPM2560.
NOTE: Parallel Arm Cutters with (S/N 163695-) will
require flow control valve kit #316-068K if your
tractor does not have flow control (turtle/rabbit
control) or if your tractor uses an open center
hydraulic system. Check your tractor’s operator’s
manual to determine your tractor’s set-up.
The flow control valve diverts excess oil back to the
tractor, which in turn keeps the back pressure down and
keeps the oil cooler.
IMPORTANT: Overheatingof the oil may occur if the flow
control kit is not installed. Damage to the o-ring in the
solenoid valve and/or the cylinders may occur if the oil
becomes overheated
1. Time the 2nd arm cylinder (arm furthest from the
tractor) from the fully extended position, to the fully
retracted position.
2. Set the tur tle/rabbit control on the tractor,or the flow
control valve (optional), so that the cylinder cycles at
5 seconds.
3. These cylinders require 5 GPM (gallons per minute)
for proper ar m function. Timing of the cylinder is the
easiest way to set the GPM.
.
Timing Procedures
Refer to Figure 2-12:
1. Set the RCP2560 in the transport position with the
arms and deck in the folded position.
2. Retract the 2nd cylinder which will raise the 2nd
arms up. Time this sequence. Time should be 5
seconds.
3. Adjust the turtle/rabbit control or the flow control
valve until the cycle time is 5 seconds.
4. The unit is now set for proper operation.
If the unit is having overheating problems through the
hydraulics, check the tractor’s operator’s manual for
power beyond hook-up.

The breakaway cylinder or tension bolt is used to
prevent structural damage to the cutter head and
parallelarms. If the cutter head strikes anobject during
forward movement, the breakaway cylinder extends allowing the cutter head and parallel arms to pivot 90
degrees to the rear. This movement is identical to that
of the tension bolt, but the big advantage of the
breakaway cylinder is that it can be easily reset using
the tractor's remote cylinder control levers.
The breakaway cylinder should be installed on the
cutter as shown in Figure 3-5. Be sure that the rod end
of the cylinder is located on the pivot lug as shown.
Connect both hoses from the cylinder to a remote
outlet on the tractor. The tension bolt should never be
used in conjunction with the breakaway cylinder.
The breakaway cylinder is designed to bypass
hydraulic fluid under high pressure when the cutter
head or parallel arms strike an object during forward
movement. Do not use any standard hydraulic cylinder
for a breakaway cylinder or damage could occur to the
unit.
NOTE: All units equipped with the breakaway
cylinderalso have a 1/2"tension bolt installed onthe
breakaway plates for shipping purposes. This bolt
must be removed after the cutter is hooked up to the
tractor.

WARNING
The following operating procedures must be carefully read
and fully understood. You are the tractor operator and are
therefore responsible for the safe operation of this unit. All
other persons must be cleared of the area. Cutter operation
must be stopped when in the vicinity of other persons.
11. After attachment to the tractor, carefully raise and
lower the cutter to ensure that the drawbar, tires,
and other equipment on the tractor do not contact
the cutter frame or PTO shaft.
12. Check all hoses and wires to be sure that they will
not contact the PTO shaft. PTO guards must be in
good condition and in place.
13. When the deck is in the transport position, and the
PTO disengaged, check to be sure the blades are
not locked (overlapped) together. The deck safety
chain must be engaged in the deck hook provided.
14. Check blades for sharpness and ensure that both
blade bolts as well as the center blade carrier hub
nut are tight. Check tractor safety equipment particularly the ROPS (Roll Over Protective
Structure) and the operator safety screen to be
sureboth are in goodworking condition. Wear your
safety glasses.
15. Removeand stow the deck safetychainjustpriorto
cutting. Adjust lower 3-point links such that the
PTO shaft is approximately level. Extend the
cutters parallel arms out and position the deck flat
on the ground.
16. Increase tractor throttle to approximately 500 RPM
and slowly engage the PTO. Initial start-up
vibration is normal, but should stop after a few
revolutions of the blade carrier. If vibration
continues, stop PTO rotation. Wait for the blade
carrier to come to a complete stop before
dismountingfromthetractor,thencheckthe blades
to be sure they are not locked together.
17. Once the cutter is running smooth increase tractor
throttle to provide for 540 PTO RPM.
IMPORTANT: If a 1000 RPM tractor PTO is being
used, engine RPM MUST be reduced to limit PTO
RPM to 540. Excessive engine speed will cause
damage to the speed increaser and other power
train components.
18. Position the cutter deck for best operator visibility.
This is normally with the arms extended to
approximately 3/4 of full extension. Adjust deck
attitude and height. Optimum ground speed will
depend on the density of the material being cut,
operatorawareness,and (in some cases) terrain.If
in doubt, reduce tractor ground speed to a
comfortable level.
!
Do not operate this cutter under any terrain conditions that
would place the tractor at an angle exceeding 30 degrees
either front-to-rear or left-to-right. Ensure that adequate
ballast weights are provided on both the front of the tractor
and left of the tractor and left hand side of cutter to assure
tractor stability. See Figure 6-1.

Breakaway Operations
This cutter is designed for breakaway of the cutter
head and parallel arms in the event the cutter head
contacts an immovable object or irregular terrain
duringforward tractor movement. The“breakaway” will
prevent structural damage to the cutter head, parallel
arms, and mainframe in the event of such contact. See
Figure 6-2.
Upon breakaway, the cutter head must be reset to the
original "home" position before normal cutting
operations can be resumed. Reset to the home
position is accomplished somewhat differently
depending on whether the cutter is equipped with the
standard tension bolt or the optional breakaway
(hydraulic) cylinder.
Tension Bolt
1. Raise the arms and deck upward to clear any
obstacles located behind the cutter deck.
2. Slowly back the tractor and cutter awayfrom those
obstacles that would interfere with rotating the
deck and arms back to the “home” position.
!
Shut off PTO power, put the tractor in park and wait for the
blades to stop rotating before dismounting from the tractor.

Breakaway Cylinder
1. Raise the arms and deck upward to clear any
obstacles located behind the cutter deck.
2. Slowly back the tractor and cutter awayfrom those
obstacles that would interfere with rotating the
deck and arms to the “home” position.
3. Use the tractor’sremote (cylinder) control to rotate
the deck/arms back to the “home” position.
IMPORTANT: Do not attempt to operate the
cutter in reverse. The breakaway mechanism will
function ONLY when the tractor is moving in a
forwarddirection. Cutter operation with the tractor in
reverse gear may cause structural damage to the
parallel arms if the cutter head strikes a solid or
immovable object.
A shear bolt is located at the rod end of the (optional)
breakaway cylinder. This bolt may shear under the
following conditions:
1. After breakaway, the operator backs the tractor
awayfrom the obstruction, but encounters an
additional obstruction or immovable object while
operating the tractor in reverse. Specifically, the
operator failed to raise the deck high enough to
clear the object before operating the tractor in
reverse.
2. The operator tried to reset the deck/arms by
backing the tractor into an obstruction rather than
using the tractor’s remote cylinder control.
3. The shear bolt has become fatigued after repeated
breakaway cycles and resets.
4. The self-locking nut used to hold the shear bolt in
place has been torqued to the point of contacting
the rod end of the cylinder and, because of
preloading causes the shear bolt to shear with
reduced effort.
IMPORTANT: Do not back the tractor to reset the deck
to “home” position. Doing so may cause severe
structural damage to the mainframe.
Breakaway Manual Reset
Figure 6-2
12267
In the event of shear bolt failure, the shear bolt MUST
be replaced with the correct replacement part (316118D). The use of a substitute part may result in
damage to the parallel arms or main frame. A single
replacement part is included with each cutter and is
located on a bracket adjacent to the upper 3-point
hitch.
IMPORTANT: Torque the self-locking nut onto the
shear bolt, but do not turn it so far as to make
contact with the clevis of the hydraulic cylinder. In
other words, the nut should be threaded onto the
shear bolt to within approximately 1/32" of contact
with the clevis. See Figure 6-3.

General Operating Instructions
The RCP2560 Series Parallel Arm Hydraulic Rotary
Cutter is uniquely versatile and a powerfully productive
cutting implement in the hands of a skilled,
knowledgeable, and responsible operator. This unit is
frequently operated on inclines in populated areas and
near high traffic. Therefore, it is absolutely essential that
no one operates this cutter without first becoming totally
familiar with the Operator’s Manual. Make sure you pay
particular attention to Section 1 on Safety Rules, Section
2 on Assembly Instructions and Set-up, Section 5 on
Transporting, Section 6 on Operating Procedures, and
Section 7 on Maintenance and Lubrication.
You may put the Rotary Cutter to work once you have
carefully read and fully understood this Operator’s
manual. Transport to the work site at a safe speed and in
a manner that allows faster moving vehicles to pass
safely. A slow moving vehicle sign should always be
properly displayed when using public roads or right-of
ways. Upon arriving at the work site, shut-off the tractor,
set the brakes, remove ignition key, and dismount to
preform the following checks:
• Remove and safely store away deck safety chain.
• Verify thatthe PTO shaft is approximately level. Adjust
3-point link if PTO shaft is not level.
• Visually inspect cutter blades. Make certain they are
not overlapped and locked together.
Return to the tractor, after preforming the above checks,
to start the engine. Extend the cutter’s parallel arm out
and position the deck flat on the ground. Adjust height of
the parallel arm and cutting deck for good visibility and
unobstructed performance. Set engine RPM at idle or
slightly above and engage PTO. Initial start-up vibration
is normal and should smooth out after a few revolutions
of the cutter blades unless the blades are locked
together. Increase tractor throttle PTO speed to 540
RPM. Proceed forward at a mowing speed that is
comfortable and will produce a quality cut for ground
conditions and material density.
The RCP2560 Rotary Cutter is designed with an
automatic breakaway cutter head and parallel arm that
releases when the unit contacts immovable objects or
irregular terrain. The cutter head must be reset to “home
position”after each breakawaybefore cutting operations
can resume. See Section 6, page 24, “Breakaway
Operations” for additional information on resetting the
cutter head to “home position”.
See“Section8: Specifications & Capacities” onpage 31.
for additional information on performance enhancing
options.
It requires patience, practice, and attention to detail to
becomeanexpertoperator on your Land Pride RCP2560
Series Cutter, but the end result is well worth the effort.

cavityplugslocatedononesideof the housing just below
themotormounting flange. Position the cutter deckinthe
transport position and remove either plug to check fluid
level. Fluid level should be within 1/2" of the top of the
port. Add 80-90 weight gearlube as required. The
capacity of the cavity is approximately 1/3 pint.

The hydraulic reservoir has an effective capacity of 35
gallons. A dipstick located on the filler cap indicates the
correct reservoir fluid level.
A filter mounted on the hydraulic reservoir is used to
clean the pump and motor system fluid. It should be
replaced after 2 years of service. A conventional 10
micron filter element should be used See Figure 7-2.
The speed increaser gearbox is mounted between the
PTO shaft and the hydraulic pump. It increases the
standard 540 RPM PTO speed to 2000 RPM at the
pump. The oil should be changed after the first 100
working hours. Successive changes should be made
after every 1500 hours or once a year. Use 80-90 weight
gearlube. Check the oil level by removing the level plug
located on the side of the case. Oil may be added by
removing the breather located at the top of the case. A
drain plug is located at the bottom of the case. See
Figure 7-3.

Blade Servicing (Replacement)
The cutter blades should be inspected on a daily basis.
They must be kept sharp and should be replaced if they
are worn excessively.
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
during rotation. Do not remove any more material than
necessary when sharpening blades.

IMPORTANT: Replace blades with genuine Land
Pride blades only.If one blade is to be replaced, the
mating blade must also be replaced. Failureto do so
will result in an out-of-balance condition that will
contribute to premature bearing failure on the
spindle hub. Factory blades are 4" wide and 25"
When replacing or sharpening the cutter blades,
examine the blade bolts, shims and blade bolt nut.
Replace if necessary. Be sure that the blades are
installed properly. The airfoil (lift) must be oriented
towards the top of the deck. The blade bolt nuts must be
torqued to 450 ft-lbs.

Blade Rotation
Figure 7-4
12271
Blade Rotation is clockwise. See Figure 7-4.
The Skid Shoes should be inspected at the beginning of
each cutting season. Original material thickness is 1/4".
They should be replaced when the material thickness is
less than 1/8" at any point. The skid shoes are
interchangeable from left to right.
Tractor Maintenance
IMPORTANT: One of the most important things you
can do to prevent hydraulic system problems is to
ensure that your tractor's reservoir remain free of
dirt and contamination. Use a clean cloth to wipethe
hose ends before attachment to your tractor.
Replace the filter element for your tractors hydraulic
systemattheprescribedintervals.Doingsowill go a long
way to prevent the occurrence of cartridge valve and
hydraulic cylinder problems on the Parallel Arm Cutter.
NOTE: Removal of the solenoid valves from the
valve block requires the removal of a 1/2" hex nut on
the end of the solenoid armature. Use care when
removing/replacing this nut. Use Locktite or other
thread locking compound when replacing and DO
NOTexert more than 3 ft lbs oftorque on this hexnut.
Remember that 3 ft lbs is slightly higher than finger
tight! See Figure 7-5. Overtightening this nut will
distort the hollow armature shaft and may result in
valve failure. See Solenoid Valve Block
12272
Solenoid Valve Block
Figure 7-5
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
cutter and any of the moving parts. It may be necessary
to scrape off compacted dirt from the bottom of the deck,
then use a garden hose to thoroughly clean the surface.
A coating of oil may also be applied to the lower deck
area to minimize oxidation.
Check the blades and blade bolts for wear and replace if
necessary. See “Section 7: Maintenance & Lubrication”
on page 27.
Inspect the cutter for loose, damaged or worn parts and
adjust or replace if needed.
Lubricate as noted in “Section 7: Maintenance &
Lubrication” on page 27.
Repaintpartswherepaint is worn or scratched to prevent
rust. Aerosol Buckskin touch-up paint is available from
your Land Pride Dealer. Order Land Pride part #821011C.
Store the cutter ina clean, dryplace. The deckshould be
positioned on a flat surface with the arms retracted and
the jack stands lowered to suitable 3-Point height.
Ensure that the main frame is stable. Use auxiliary
supportsorpostsifnecessary to prevent the possibility of
the unit tipping over.
