Section 1: Assembly & Set-up
a. Make sure cutter and tractor PTO shafts are level
PTO Hook-up
with each other and cutter deck is securely
supported at this height with support blocks.
IMPORTANT: Do not engage tractor PTO until
driveline is fully connected and hydraulic fluid has
been added to the cutter reservoir.
b. Pull driveline apart into two sections as shown in
Figure 1-6.
c. Attach outer driveline universal joint to tractor
PTO shaft and inner driveline universal joint to the
speed increaser shaft. Pull on each driveline
section to be sure universal joints are secured.
IMPORTANT: A quick hitch may be used, but is not
recommended because it moves the cutter deck
back about 5" and impedes operator visibility.
d. Hold driveline sections parallel to each other to
determine if they are too long. The inner and outer
shields on each 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 shield and make a mark at
this location on the inner and outer shields.
driveline breakdown. A rotating driveline must not
exceed an angle of 25 degrees up or down.
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.

IMPORTANT: Always check driveline minimum
length during initial setup, when connecting to a
different tractor and when alternating between using
a quick hitch and a standard 3-point hitch. More than
one driveline may be required to fit all applications.
IMPORTANT: It is necessary to aligning the tractor’s
PTO shaft level with the Rotary Cutter’s speed
increaser shaft when checking driveline minimum
length. Too long a driveline can damage tractor,
gearbox and driveline.

The control stick will be equipped with a Float Switch and
LED light only if the cutter deck is equipped with gauge
wheels.
The transport safety chain should always be hooked to
the deck hook when cutter is folded up. Otherwise, the
operating levers and/or push button switches could be
bumped or hoses could burst allowing deck to fall and
cause damage to cutter, tractor, and anyone nearby.
Press and release the Float Switch to turn float function
“ON”. Press and release the switch again to turn float
function “OFF”. Toggling the switch back and forth in this
fashion will turn float function “ON” & “OFF” repetitively.
LED light illuminates only when the Float Switch is “ON”.
Before unhooking the transport safety chain, make sure
the arm and deck cylinders are retracted and if available,
the Float Switch is set to “OFF”. Do not force safety chain
off of the deck hook. If safety chain does not remove
easily, investigate the problem and correct before
continuing. Once unhooked, store safety chain on
storage hook for safe keeping.
Float Switch Turned ON:
When “ON”, the Float Switch allows the deck to be
carried on the gauge wheels. “Deck UP/DOWN” and
“ARM 2 OUT/IN” push button switches are bypassed
allowing deck position to change with the terrain.
“ARM 1” push button switches are not bypassed.
Therefore, “ARM 1 IN” switch can be pressed to move
deck closer and to raise parallel arms for clearing
objects. “ARM 2 OUT” switch can be pressed to move
deck farther away from tractor.
The deck can be raised with “ARM 2 OUT” push button

Tractor Flow Control
Refer to Figure 2-2:
Hydraulic Flow Control Settings
The hydraulic cylinders require 5 GPM (gallons per
minute) to function properly. This is set by adjusting the
flow control valve(s) and then timing how long it takes for
the cylinder to fully retract. The valve is adjusted
correctly when it takes 5 seconds to retract.
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.
Cutter Flow Control
Refer to Figure 2-1:
IMPORTANT: Oil overheating may occur if flow
control is not achieved. Damage to o-rings in the
solenoid valve and/or in the cylinders may occur if oil
becomes overheated.

5. Extend parallel arms and deck cylinder as follows:
!
WARNING
The Parallel Arm Rotary Cutter is designed to cut grass and
brush up to 2” in diameter. Using this cutter for another type
of work can damage the drive components, deck and support
frame.
Deck without gauge wheels:
a. Starting with “ARM 1”, extend the two parallel arms
switching back-and-forth from “ARM 1” to “ARM 2”
until both arms are positioned as needed.
b. Extend “DECK” cylinder until deck is parallel to the
ground.
!
WARNING
Do not operate this cutter under any terrain conditions that
would place tractor at an angle exceeding 30 degrees either
front-to-rear or left-to-right. Make sure adequate ballast
weights are provided on both the front of tractor and left of
tractor and left hand side of cutter to assure tractor stability.
c. Adjust deck and parallel arms to locate cutter for
best operator visibility. Normally, this is with arms
extended out approximately 3/4 of full extension.
Deck with gauge wheels:
a. Make certain tractor control levers are set to center
detent position and if available, Float Switch on the
control stick is “OFF”.
!
DANGER
b. Starting with “ARM 1”, extend the two parallel arms
switching back-and-forth from “ARM 1” to “ARM 2”
until both arms are positioned as needed.
Rotary Cutters have the ability to discharge objects at high
speeds. Front & rear deck safety shields are required!
c. Extend “DECK” cylinder until deck is resting on its
gauge wheels.
!
DANGER
Do not use deck as a fan. Cutting blades are not properly
designed or guarded for this use. Using deck as a fan can
result in injury and/or death.
d. Switch “ARM 2” and “DECK” cylinders to float
position.
• Solenoid controlled cylinders:

Specifically, the operator did not raise the deck high
enough to clear the object before backing up.
IMPORTANT: Your Rotary Cutter is equipped with
free swinging cutting blades to reduce shock loads
to the cutter when striking obstacles. The cutting
blades can lock together while transporting. Always
check for locked blades before starting to cut.
• The operator tried to reset the deck and parallel arms by
backing the tractor into an obstruction rather than using
the tractor’s remote cylinder control.
• The shear bolt has become fatigued after repeated

breakaway and reset cycles.
• The shear bolt self-locking nut has been tightened
against the clevis causing a pre-loaded stress on the
bolt and the bolt to shear at a reduced breakaway force.
24631
7. Once cutter is running smoothly, increase tractor PTO
speed to cutter rated PTO speed. Stop PTO rotation
immediately if vibration occurs. Wait for the PTO to
come to a complete stop and then dismount from the
tractor to check for probable causes.
8. Optimum ground speed will depend on density of
material being cut, terrain and operator skill. If in
doubt, change gears to reduce tractor ground speed
to a comfortable level.
Shear Bolt Space
Figure 3-1
Breakaway Operating Procedures
Refer to Figure 3-1:
Replace shear bolt with correct replacement part (Land
Pride Part No. 802-885C). A substitute shear bolt may
result in damage to the parallel arms and/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.
The deck and parallel arms are designed to breakaway
should the cutter head make contact with an immovable
object or irregular terrain during forward travel. This
“breakaway” feature will protect the cutter against
structural damage by allowing the deck and parallel arms
to pivot backwards.
IMPORTANT: Install self-locking nut onto shear bolt
until nut is threaded to within approximately
1/32" of contact with clevis as shown in Figure 3-1.
Upon breakaway, the cutter head must be reset to
original “home” position before normal cutting operations
can resume.
Un-hooking the Rotary Cutter
IMPORTANT: Do not attempt to operate cutter in
reverse. The breakaway mechanism will function
correctly ONLY while tractor is moving forward.
Cutting while backing up may cause structural
damage to the parallel arms and deck if cutter head
strikes a solid or immovable object.
The following steps should be done when un-hooking the
cutter.
IMPORTANT: Make sure transport safety chain is
attached to the Rotary Cutter deck and Float Switch,
if available, is “OFF” before un-hooking the cutter.
1. Raise arms and deck up to clear any obstacles
located behind the cutter deck.
1. Park on a level solid surface.
2. Lower cutter frame to level ground or onto blocks
supporting the frame just above ground level.
2. Slowly back cutter away from any obstacles that will
interfere with pivoting unit back to “home” position.
3. Engage tractor park brake, shut tractor engine off and
remove switch key before dismounting from tractor.
3. Use tractor’s remote (breakaway cylinder) control to
pivot unit back to “home” position.
4. Unhook control stick from connector at the cutter and
power source. Store control stick in a dry location.
Cylinder Shear Bolt
Refer to Figure 3-1:
5. Disconnect driveline from tractor PTO shaft.
6. Disconnect hoses from tractor duplex outlets.
A shear bolt is located at the rod end of the breakaway
cylinder. This bolt may shear under the following
conditions:
7. Un-hook 3-point hitch from tractor. Reinstall hitch
pins, linch pins and hair pin cotters in cutter hitch for
storage.
• After breakaway, the operator backs the tractor away
from the obstruction, but encounters an additional
obstruction or immovable object while backing up.

Section 3: Operating Procedures
General Operating Instructions
Upon arriving at the work site, shut-off tractor, set
brakes, remove ignition key, and dismount to preform the
following checks:
1. Remove and safely store away transport safety chain.
2. Verify that the PTO driveline is approximately level.
Adjust the height of the lower 3-point arms if PTO
driveline is not level.
3. Visually inspect cutter blades. Make certain they are
not overlapped and locked together.
After performing the above checks, return to the tractor
and start the engine. Extend cutter’s parallel arms out
and position the deck flat on the ground. Adjust cylinder
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. Shut off the PTO, raise the deck and inspect the
blades if the deck continues to vibrate. Otherwise,
increase tractor throttle PTO speed to 540 rpm for
RCP2660 and RCP3060 series cutters and 1000 rpm for
RCPM2660 and RCPM3060 series cutters. Proceed
forward at a mowing speed that is comfortable and will
produce a quality controlled cut for ground conditions
and material density.
The Rotary Cutter is designed with automatic breakaway
arms that release when the unit contacts immovable
objects or irregular terrain. Arms must be reset to “home
position” after each breakaway before cutting operations
can resume. See “Breakaway Operating Procedures” on
For additional information on performance enhancing
options, see “Section 8: Features & Benefits” on page 45
It requires patience, practice, and attention to detail to
become an expert operator of your Land Pride Parallel
Arm Rotary Cutter. The end result is well worth the effort.

Refer to Figure 4-1:
Hydraulic Control Options
There are four options available.
1. Measure width and thickness of the tractor ROPS bar
to determine if the clamping hardware supplied will be
adequate.
Solenoid Control with Standard Deck Option:
Cutting deck is supplied without gauge wheels. Two
duplex outlets are required to operate arm cylinders,
deck pivot cylinder and breakaway cylinder. Arm and
deck cylinders are solenoid activated with momentary
push button switches at the control stick. Breakaway
cylinder is controlled by tractor lever.
2. Compare parts list and quantities with parts received.
Report any missing or damaged items to your dealer.
NOTE: To determine the best location for the
protective shield, the cutter should be connected to
the tractor, parallel arms should be fully extended
and the deck should be approximately horizontally
level.
Tractor Control with Standard Deck Option:
Cutting deck is supplied without gauge wheels. Four
tractor duplex outlets are required to operate the arm
cylinders, deck pivot cylinder and breakaway cylinder.
Tractor levers operator all cylinders.
3. Carefully remove the shield from the shipping carton
and temporarily position it on the inside surface of the
ROPS bar. Locate shield forward/back and up/down
to provide the best overall coverage for the tractor
operator. Use a spirit level to level the shield before
marking. Mark frame location with a pencil on each
side of the ROPS bar; and mark vertical ROPS
location on the shield frame.
Solenoid Control with Valve Float Deck Option:
Cutting deck is supplied with gauge wheels for
controlling deck height and angle in lieu of momentary
push button switches. Two duplex outlets are required to
operate arm cylinders, deck pivot cylinder and
breakaway cylinder. Arm and deck cylinders are solenoid
activated with momentary push button switches at the
control stick. An “ON/OFF” push button Float Switch is
included on the control stick to bypass “ARM 2” and
“DECK” solenoids allowing the deck to float on its gauge
wheels. Breakaway cylinder is controlled by tractor lever.
4. Position protective shield (#5) on a flat work surface.
Locate one of the flatbars (#4) next to the pencil marks
to determine which set of holes will clear the vertical
marks for the ROPS location. Mark hole location and
drill two 1/4" diameter holes through the shield frame.
Similarly mark and drill two additional holes for the
lower clamp location.
Tractor Control with Hose Float Deck Option:
Cutting deck is supplied with gauge wheels for
controlling deck height and angle in lieu of control levers.
Four duplex outlets are required at the tractor to operate
the arm cylinders, deck pivot cylinder and breakaway
cylinder. Tractor levers operator all cylinders. “ARM 2”
and “DECK” control levers are set in float position when
carrying the deck on its gauge wheels.
5. Attach shield to the inside surface of the ROPS bar
with 1/4" x 4" cap screw (#6), 1/4" flat washer (#3),
1/4" lockwasher (#2) and 1/4" nut (#6).
Operator Protective Shield Option
An optional operator protective shield is available for use
on tractors not equipped with cabs or other protective
shielding. This shield is a “universal” type and is suitable
for attachment to a conventional Roll Over Protective
Structure (ROPS) that is already attached to the tractor.
It is constructed of an extruded aluminum frame and
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" x 5" and 2 1/2" x 6". Other
sizes may require longer mounting bolts and/or custom
flatbars. Installation requires that 4 mounting holes be
drilled in the frame of the shield. No modification is made
to the ROPS.

Breakaway Cylinder Plumbing
Refer to Figure 5-7:
Pressure Shut Down Valve Operation
Refer to Figure 5-7:
!
CAUTION
The breakaway cylinder is designed to bypass hydraulic fluid
under high pressure when 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.
The standard pressure shut down valves supplied with
the breakaway cylinder inherently leak a small amount of
oil allowing the deck to drift back during field operation.
When required, reset the cutter deck forward during field
operation using the tractor's remote cylinder control
levers.
The breakaway cylinder is used to prevent structural
damage to the cutter head and parallel arms. If the cutter
head strikes an object during forward movement, the
breakaway cylinder extends - allowing the parallel arms
and cutter deck to freely pivot 90 degrees to the rear.
An optional replacement pressure shut down valve is
available that greatly reduces the frequency of cutter bar
drift but takes continuous force to move the deck back.
(Deck does not freely pivot back as it does when
using the standard pressure shut down valves).
IMPORTANT: A 1/2" bolt is installed for shipping
purposes only. This bolt must be remove before
connecting the hydraulic hoses to the tractor.
See Land Pride’s Parts Manual No. 316-111P for
ordering either the standard or optional pressure shut
down valves. Order only genuine Land Parts from your
local Land Pride Dealer.

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:
Maintenance
Proper servicing and adjustment is the key to the long life
of any implement. With careful and systematic
inspection, you can avoid costly maintenance, time and
repair.
a. Do not remove more material than necessary.
b. Do not heat and pound out a cutting edge.
After using your Rotary Cutter for several hours, check
all bolts to be sure they are tight.
c. Do not grind blades to a razor edge. Leave a blunt
cutting edge approximately 1/16” thick.
Replace any worn, damaged or illegible safety labels by
obtaining new labels from your Land Pride Dealer.
d. Always grind cutting edge so end of blade remains
square to cutting edge and not rounded.
Cutter Blades
e. Do not sharpen back side of blade.
!
f. Both blades should weigh the same after
WARNING
Always secure cutter deck in the up position with solid supports
before servicing underside of deck. Never work under
equipment supported by hydraulic jacks. Hydraulic jacks can
drop equipment if controls are actuated or if hydraulic lines
burst. Either situation can drop the cutter instantly even when
power to the hydraulic system is shut off.
sharpening with not more than 1 1/2 oz. difference.
Refer to Figure 6-1:
6. Carefully check cutting edges of blades in relation to
blade carrier rotation to ensure correct blade
placement. Blade Rotation is clockwise with cutting
edge leading. Airfoil (lift) must be oriented towards the
top of the deck.
!
DANGER
Always disconnect main driveline from tractor PTO before
servicing underside of deck. Cutter can be engaged if tractor is
started resulting in damage to the cutter, bodily injury and/or
death.
Always inspect cutting blades before each use. Make
certain they are properly installed and are in good working
condition. Replace any blade that is damaged, worn, bent,
or excessively nicked. Small nicks can be ground out
when sharpening.
IMPORTANT: Replace cutting blades with genuine
Land Pride blades only. Blades must be replaced in
mating pairs. Not replacing both blades will result in
an out-of-balance condition that will contribute to
premature bearing break down on the spindle hub
and create structural cracks in cutter housing. Factory
blades are 4" wide by 25" long.

WARNING
Excessive wear on skid shoes may cause inadequate operation
of cutter and create a safety hazard!
IMPORTANT: Locknuts can loose their ability to
lock properly once removed. Therefore, always use
a used blade nut or plain nut in steps step 7 & step
8 below and then replace used nut with new
locknut in step step 9.
Inspect skid shoes at the beginning of each cutting
season. Check all skid shoes weekly for wear and
replace if necessary. Original material thickness is 1/4".
They should be replaced when the material thickness is
less than 1/8" at any point. They are interchangeable
from left to right.
7. Start by assembling blades without shim (#2). Insert
blade bolt (#1) through blade (#3), dish pan (#4) and
flat washer (#5). Temporary secure blade with a used
1 1/8"-12 nut. Draw nut up snug. Do not tighten.

Solenoid Valve Block
Cutter Storage
Refer to Figure 6-4:
Clean the Rotary Cutter at the end of the working season
or when the cutter will not be used for a long period.
IMPORTANT: DO NOT exert more than 3 ft. lbs. of
torque on the hex nut securing the solenoid
armature. Remember, 3 ft. lbs. is slightly more than
finger tight! Overtightening this nut will distort hollow
armature shaft and may result in valve break down.
1. Store control stick in a clean dry location. Do not
leave it out in the rain. Clean control stick with a
damp rag. Do not submerge control stick in water or
clean with high pressure wash.
2. Clean off any dirt or grease that may have
accumulated on the deck, gearbox and on any of the
moving parts. Scrape off compacted dirt from the
bottom of the deck and then wash the surface
thoroughly with a garden hose. A coating of oil may
also be applied to the lower deck area to minimize
oxidation.
The 1/2" hex nut on the end of the solenoid armature
shaft must be removed to remove a solenoid valve from
the valve block. Use care when removing and replacing
this nut. Do not tighten nut with more than 3 ft. lbs. of
torque.
See your nearest Land Pride Dealer to purchase new
solenoid vales and/or seal kits.
3. Check blades and blade bolts for wear and replace if
necessary. See “Section 6: Maintenance &
4. Inspect for loose, damaged or worn parts and adjust
or replace as needed.
6. Store the cutter in a clean, dry place. The deck should
be positioned on a flat surface with arms retracted and
the jack stands lowered to suitable 3-Point height.
Ensure that the main frame is stable. Use auxiliary
supports or posts if necessary to prevent the
possibility of the unit tipping over.
7. Repaint parts where paint is worn or scratched to
prevent rust. Aerosol Buckskin touch-up paint is
available from your Land Pride Dealer.

Tractor Maintenance
One of the most important things you can do to prevent
hydraulic system problems is to ensure that your tractor's
reservoir remains free of dirt and contamination.
Use a clean cloth to wipe hose ends before attaching
them to your tractor. Replace filter element for your
tractor’s hydraulic system at the prescribed intervals.
These simple maintenances will go a long way to prevent
the occurrence of solenoid valve and hydraulic cylinder
problems on the Parallel Arm Cutter.
