by trained personnel using the correct tools and equip-
ment.
2. Do not re-inflate a tire that has been run flat or seriously
under inflated. Have it checked by qualified personnel.
3. When removing and installing wheels, use wheel handling
equipment adequate for the weight involved.
15. Wear proper eye protection to prevent injury from flying
objects.
16. Keep PTO shielding in place and in good condition. do not
operate cutter with shields missing.
17. Always use proper PTO speed or machine damage may re-
sult. This cutter is designed to be used with a tractor using
a 540 or 1,000 rpm rear PTO. Important: Never should
a machine equipped for 540 rpm PTO be operated by a
tractor equipped with a 1,000 rpm PTO nor should a 1,000
rpm PTO machine be operated with a tractor equipped
with a 540 rpm PTO.
18. In order to maintain steering control, add ballast to trac-
tor. To determine the amount of ballast required refer to
your tractor operator’s manual.
19. Before performing maintenance, disconnect PTO driveline
and hydraulic hoses and securely block cutter on safe sup-
porting stands. Do not position stands under axle or wheel
supports.
20. Transport cutter with transport axle lock pin installed and
wing lock latches in place.
21. Escaping hydraulic fluid under pressure can have suffi-
cient force to penetrate the skin. Check all hydraulic hoses
before applying pressure. Fluid escaping from a very
small hole can be almost invisible. Use paper or card-
board, not body parts, to check for suspected leaks. If in-
jured, seek medical assistance from a doctor that is
familiar with this type of injury. Foreign fluids in the tissue
must be surgically removed within a few hours or gangrene
will result.

to allow fluid to escape.
c. Shorten inner and outer sliding profiles by the
same length as the guard tubes.
b. Slowly activate the tractor control valve to purge
any trapped air from the system.
d. Proper overlap is a minimum of one-half the
length of each tube, with both tubes being of equal
length.
c. Tighten each fitting.
e. Round off all sharp edges and remove burrs.
Grease sliding profiles.
The optional center deck lift cylinder is purged in the same
manner. The cutter should be lowered to the ground or the

an optional control valve kit is available from your
dealer.
11. The PTO Constant Velocity shaft or conventional PTO
(if used) should be checked for adequate clearance
under all ranges of cutter height depending on the
tractor being used. With the PTO shaft attached to the
tractor, slowly raise and lower the cutter to upper and
lower limits while observing clearance distance be-
tween hitch and PTO shaft. If an interference condi-
tion exists, it may be necessary to modify the drawbar
height/length of the tractor.
10. Cycle the hydraulic system by raising and lowering the
center deck cylinder and the wing fold cylinders. If op-
eration is sluggish, it may be necessary to purge the
system of trapped air.

DANGER!
Hydraulic fluid under pressure can penetrate skin. Wear protec-
tive gloves and safety glasses or goggles when working with hy-
draulic 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 surgically removed within a few
hours by a doctor or gangrene may result.

WARNING!
The following operating procedures should be carried out by
the tractor operator. Other persons should be cleared of the
area even during cutter setup. cutter operation should be
stopped when in the vicinity of other persons.
Optimum Ground speed depends on the density of the
material being cut, the horsepower rating of the tractor,
and (in some cases) terrain.
If the cutter-to-tractor PTO is a standard conventional
shaft, avoid tractor-to-cutter turning angles exceeding 35˚.
If equipped with a Constant Velocity PTO shaft, the turn-
ing angle may be increased to 80˚. These extreme angles
are intended for intermittent usage only and not prolong
usage. Plan your field cutting to minimize the number of
turns as well as the extreme angles where turns are
necessary.
Refer to Figure 2-1:
1. Raise the center deck to sufficient height to disengage
the transport link (#1) . Remove the transport link pin
(#2), lower the link arm, then replace the link pin to the
storage position.
NOTE: The center deck height is controlled with the
standard ratchet jack or the optional hydraulic lift cyl-
inder.
2. Inspect the wing blade carriers and blades prior to
lowering the wings. The wing deck blades may be-
come locked together (overlapped) when the wings
are raised to transport position. Operating the cutter
under such circumstances will result in severe deck vi-
bration. Inspect the wing decks for a locked blade con-
dition prior to power-on operation. Use a pry bar or
other tool to separate the blades if necessary.
11934
3. The automatic wing latches on each wing must be re-
leased prior to lowering the wings. If the wing latch
handles cannot be moved, it may be necessary to
raise the wings to the fully closed position. Release
wing latch and then lower the wings to full-down posi-
tion.

Wing Deck Tailwheel
Rubber Bumper Adjustment
Refer to Figure 3-4:
5. This setting should not require further adjustment un-
less the drawbar height is changed or different size
tires are used.
6. The cutting height can be adjusted by extending or re-
tracting the hydraulic cylinder or rachet jack located
at the rear center of the cutter.
NOTE: Cutter to be adjusted on level ground
Wing Deck Level Adjustments
The tailwheel adjustment nut, Figure 3-4, is to be adjusted
with wings down and in level position. (Weight of cutter will
set the rubber bumpers). Snug nut up, plus one additional
turn. Bumpers are then set for optimal cushioning
condition!
IMPORTANT: Ensure that Center Deck Level Adjustments
have been made before proceeding with wing deck level
adjustments.
NOTE: Bumpers will need to be checked periodically
for over-compression. When dimension "A" gets to
1", the cushions should both be replaced. Bumper
part number is 312-313D
!
CAUTION!
Engage parking brake, shut off tractor, remove key and disen-
gage PTO before making any height adjustments!
Refer to Figure 3-3:
1. Lower both wings to full down position.
2. Place a level on the wing axle rockshaft to determine
initial up or down position (left/right).
3. Raise the wing to full vertical position.
4. Remove the cotter pin (#1) and clevis pin (#2), from
the back end of the axle link (#3). The axle link is then
shortened to raise the wing or lengthened to lower the
wing. Shorten the axle link by rotating the clevis end
clockwise or lengthen by turning counterclockwise.
Reattach to the rockshaft lug.

Section 5 Maintenance and Lubrication
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 in-
spection, you can avoid costly maintenance, time and re-
pair.
NOTE: Blades for the wings & center deck are 25"
long, Note rotation as shown in Figure 5-1.
For safety reasons, each maintenance operation must be
performed wiht tractor PTO disengaged, the cutter low-
ered completely to the ground or on safely supported
blocking, tractor engine shut off and ignition key removed.
1. After using your cutter for several hours, check all
bolts to be sure they are tight.
2. After transporting your cutter for several hours, check
all wheel lugs, bolts and nuts to be sure they are tight.
Always maintain proper air pressure in the tires.
NOTE: Check tightness of bolts periodically, using
818-268C
Blade Rotation
Figure 5-1
Service Cutting Blades
1. Both blades on each dishpan 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.
4. Blade Dishpan Replacement:
Dishpan nut on gearbox output shafts should be torqued
to 450 foot/pounds and cotter pin installed in nut with legs
securely bent around nut.
IMPORTANT: Replace blades with genuine Land Pride
blades only. If one blade is to be replaced, the mating
blade {on the same carrier} must also be replaced.
Skid Shoe Service & Replacement
The center deck skid shoes should be checked periodical-
ly for wear and replaced is necessary. Order center deck
skid shoe Land Pride part #312-218H. No adjustment is
required.
NOTE: Do not remove any more material than nec-
essary when sharpening blades.
!
CAUTION!
2. Both blades on each dishpan should weigh the same af-
ter sharpening.
Skid shoe replacement must be done with the deck raised to the
transport position and securely blocked. Engage parking brake,
shut off tractor, remove key and disengage PTO before adjusting
or replacing these parts.
3. When replacing or sharpening the cutter blades, exam-
ine bolts and hardware for excessive wear and replace if
necessary.
a. Torque blade bolt lock nut to 450 ft. pounds. An ex-
tended cheater bar may be required to achieve
proper torque.
!
WARNING!
Excessive wear on skids may cause inadequate operation of cut-
ter and create a safety hazard!
b. Carefully check the cutting edges of the blades in re-
lation to the blade carrier rotation diagram below to
ensure correct blade placement.
The wing deck skid shoes should be checked periodically
for wear. Excessive leading edge wear can be repaired by
interchanging the LH wing skid with the RH wing skid. If
both leading edges have been worn down, order skid shoe
Land Pride part # 312-446H.
!
CAUTION!
Installation of the longer blades on the wing decks will cause an
immediate operating hazard.
Skid Shoes
To replace center deck skid shoes:
Refer to Figure 5-2:
a. Attach skid shoe to cutter, using four 1/2" bolts
lock washers and hex nuts.
b. Repeat for opposite skid shoe.

Section 5 Maintenance and Lubrication
1. Tighten all 4 nuts uniformly until the spring load is low
enough that the clutch slips freely with the PTO en-
gaged.
To replace wing deck shoes:
Refer to Figure 5-3:
a. Attach skid shoe to cutter, using three 1/2" car-
riage bolts flat washers, lock washers and hex
nuts.
2. Turn nuts fully back. Clutch is ready for use.
Storage
1. 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 accumulat-
ed on the cutter and any of the moving parts. It may be
necessary to scrape off compacted dirt from the bot-
tom of the deck, then use a garden hose to thoroughly
clean the surface.
b. Repeat for opposite skid shoe.
Clutch Run-In
Refer to Figure 5-4:
2. Check the blades for wear and replace if necessary.
See "Maintenance & Lubrication".
3. Inspect the cutter for loose, damaged or worn parts
and adjust or replace if needed.
4. Lubricate as noted in "Maintenance & Lubrication"
beginning on page 19.
Clutch Run-In
Figure 5-4
5. Repaint parts where paint is worn or scratched to pre-
vent rust. Aerosol Buckskin touch-up paint is avail-
able from your dealer. Order Land Pride part #821-
011C.
10103
The clutch should slip during operation to protect the cut-
ter from excessive loads.
6. Replace all damaged or missing decals.
Prior to initial operation and after long periods of inactivity,
the Friction Clutch should be "run-in".
7. Store the cutter inside if possible. Inside storage will
reduce maintenance and make for a longer cutter life.
