properly before going to full power.
3. Thegroundspeeddependson twothings: thedensity
of the material being cut, and the size of the tractor.
Never run fast enough to overload the tractor.
4. It is important to maintain correct RPM PTO speed.
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 brush 1”
maximum diameter.
!CAUTION
Damage may occur if exceeding the rated cutting capacity of
the cutter!
!CAUTION
Do not overspeed PTO or machine damage may result. This
cutter is designed to be used with tractors having a 540 RPM
rear PTO. Know what your tractor specifications are.
Leveling Procedure
There are 5 primary adjustments that should be made
prior to actual field operation:
1. Deck level from left to right
2. Tractor top link length
3. Tractor lower link height
4. Tailwheel height
5. Cutter slightly higher in the rear than the front.

Maintenance
Properservicingandadjustmentcanincreasethelifeofany
implement.Withcarefulandsystematicinspection,youcan
avoid costly maintenance, time and repair.
After using your cutter for several hours, check all bolts to
be sure they are tight.
Replace any worn, damaged or illegible safety labels by
obtaining new labels 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
re-ground at the same time to maintain proper
balance in the cutting unit.
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. Torque blade bolt lock nut to 450 ft. pounds. An
extended cheater bar may be required to achieve
proper torque.
If replacing dishpan, nut on gearbox output shaft should
be torqued to 450 foot/pounds and cotter pin installed in
nut with legs securely bent around nut.
Shearbolt Driveline
Shear Bolt Replacement
The Standard Shear Bolt Driveline is secured to the cutter
withashearboltforprotectionofthedrivelineandgearbox.
The shearbolt is designed to shear off when the blade
impacts objects that the cutter is not designed to cut
through.Shouldtheshearboltneedreplaced,replacewith
Land Pride part #802-264C. Refer to page 9 Figure 1-2.
Driveline Clutch (Optional)
Cutter drive components are protected from shock loads
by a two plate slip-clutch. The clutch must be capable of
slippageduring operationto protectthegearbox,driveline
and other drivetrain parts.
Prior to initialoperationand afterlongperiods ofinactivity,
the clutch should be "run-in" to remove any oxidation that
may have accumulated on the friction surfaces.
!CAUTION
Engage parking brake, disengage PTO, shut off tractor, and
remove key before making any of the following adjustments.
Clutch Run-In
Refer to Figure 4-1:
1. Using a pencil or other marker, scribe a line across the
exposed edges of the clutch plates and friction discs.
2. Carefully loosen each of the 8 spring retainer nuts on
theclutchhousing atotalof EXACTLY2 revolutions. 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 tractor and engage the PTO drive for 2-3
seconds to permit slippage of the clutch surfaces.
DisengagethePTO,thenre-engageasecondtimefor
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
markings made on the clutch plates have changed
position. If any two marks on a friction disc and plate
are still aligned, this indicates that slippage has not
NOTE: Care should be taken in order not to remove
any more material than necessary when sharpening
blades.
IMPORTANT: Replace blades with genuine Land
Pride blades only. Blades must be ordered and
replaced in pairs.
IMPORTANT: A snap ring (Land Pride part
#800-079C) is installed so that driveline does not
come loose from the gearbox should the shearbolt
shear.

separate the friction discs, see "Clutch Assembly
and Disassembly", on page 16.
5. Tighteneachofthe8springretainernutsontheclutch

clutch setting pressure.
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 16, to adjust for proper spring length.
Clutch Assembly and Disassembly
If the clutch run-in procedure, (see "Clutch Run-In"on
page15),indicated thatone ormoreof thefrictiondiscsdid
not slip, the clutch must be disassembled to separate the
friction discs. Refer to the Parts Section of this manual for a
detailed parts breakdown.
Refer to Figure 4-2:
To disassemble the clutch, first remove the spring retainer
nuts (#8), springs (#1) and bolts (#3) from the assembly.
Each friction disc (#4) must then be separated from the
metal surface adjacent to it. Inspect all parts for excessive
wear and condition. Clean all parts that do not require
replacement.
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 may be damaged and should
be replaced. Heat build-up may also affect the yoke joints.
Install new friction discs if needed and reassemble all
components in proper order. Progressively tighten each
spring retainer bolt until the spring length is 1.010 inches.

Storage
Attheendoftheworkingseasonorwhenthecutterwillnot
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,
see "Service Cutting Blades", page 15.
3. Inspect the cutter for loose, damaged or worn parts
and adjust or replace as needed.
4. Lubricate as noted in "Lubrication" starting on
page 17
5. Store the cutter inside if possible for longer cutter life.
6. Repaint parts where paint is worn or scratched to
prevent rust. Ask your dealer for Aerosol Land Pride
Beige touch-up paint part #821-011C.
