1-2 DESCRIPTION
The MP-3132, (figure 1-1), is designed for turf
maintenance applications where a high quality
of cut on turf grasses is required.
Three sets of counter- rotating blades (per
deck) continue to cut the grass clippings sev¬
eral times before allowing the tiny pieces to
fall to the ground. This eliminates a build up
of grass residue on top of the turf, (the FP-
3132 is exactly like the MP-3132 minus the
mulching blades) The caster wheel arrange¬
ment along with the flexible, floating deck at¬
tachment, the standard front mounted rollers
and the under deck roller all work together to
give an even cut and minimize scalping.
NOTE: The inside rear wheel on the wing
mower decks and both the front wheels on the
rear mower deck are rigidly mounted and are
not designed to caste.
Power from the tractor is transmitted through
a telescoping driveline to a gearbox arrange¬
ment, which allows either wing unit to be
folded up to 30° while still operating. Power is
passed to the spindle housings by a B-
section, Kevlar reinforced belt. Drive train
protection is provided by belt slippage.
SECTION II
PREPARATION FOR USE
Before operation, service all locations outlined in Section 4-2 “Lubrication” and remove transport lock
pins from mower decks as shown in Figure 3-4. Unpin inside wing tires and reposition into a trailing posi¬
tion and re-pin in place. Break in the mower in a static condition at half throttle for 30 minutes. Inspect
all belts for proper tension; check gearboxes for proper oil levels and check to make sure blade spindles
are not overheating._

plished by adjusting the tractor draw bar height,
also by leveling the mower frame by use of the
adjustable jack stand.
If after properly leveling the mower frame the
draw bar height is less than 8”, a standard pull pin
may be too long. To prevent turf damage in un¬
even terrain, the standard pin should be replaced
with a 1” X 5” Grade 5 bolt with locknut securely
tightened.

SECTION III
OPERATING INSTRUCTIONS
3-1 GENERAL
SAFETY
Only qualified people familiar with this operator’s
manual and tractor operator’s manual should oper¬
ate this machine. Operator should wear hardhat,
safety glasses and safety shoes. The operator
should read, understand and practice all safety
messages shown on the caution, warning and
danger decals affixed to the mower to avoid seri¬
ous injury or death. It is recommended that trac¬
tors be equipped with Rollover Protective System
(ROPS) and a seat belt must be used. Before
beginning operation, clear work area of any ob¬
jects that may be picked up and thrown, check for
ditches, stumps, holes or other obstacles that
could upset tractor or damage mower. Always
lower mower to ground and allow blades to come
to a complete stop, having set parking brake and
turn off the tractor’s engine before leaving the trac¬
tor operator’s seat.
NOTE: Before initial operation the MP-3132 and
FP-3132 should be connected to the tractor for a
30-minute “run in” cycle. During the “run in”
phase, the tractor should be operated at only half
throttle. The “run in” cycle is complete, ALL
belts should be inspected for proper tension and
if adjustments are necessary, refer to Mainte¬
nance Section.
3-2 CUTTING HEIGHT ADJUSTMENT
The mower should be operated at the highest po¬
sition that will give desired cutting results. This will
help prevent blades from striking the ground, re¬
ducing blade wear and unnecessary strain on the
machine. Cutting too much material may reduce
mulching action and leave visible clippings on the

B. Remove pin securing caster stem to caster arm.
Remove caster stem from caster arm.
C. Place amount of spacers on caster stem to give
desired cutting height. With no spacers on the bot
tom, a 3/4" cutting height is given. (Figure 3-1)
D. Reinstall caster stem into caster arm. Place re¬
maining spacers on caster stem above caster arm
and install pin to retain.
E. Repeat operation for all caster wheels. Make cer¬
tain all wheels are adjusted to the same height.

B. Start tractor. Lower cutter decks until they are
supported by caster wheels and hydraulic cyl¬
inders are fully extended to allow mechanical
float to operate. (Figure 3-2)
When mowing across slopes, yawing or skew¬
ing may occur as the mower slips sideways,
which may cause streaking. In this case, mow¬
ing up and down slopes should be done to
eliminate skewing.

TIVE SYSTEM AND THAT A SEAT BELT
BE USED FOR ALL OPERATIONS
C. With tractor at idle speed, engage PTO drive.
Advance throttle to 540 PTO rpm.
D. Place tractor in low gear and begin cutting.
Tractor forward speed should be controlled by
gear selection, not engine speed. For maximum
cutting efficiency, forward speed should allow
mower to maintain a constant maximum blade
speed.
If tractor engine or cutter stalls, do not slip trac¬
tor clutch to allow engine to retain speed, as this
will exert undue strain on the implement drive
train. When stalling occurs, disengage PTO
drive, move to a cut area, set tractor throttle to
idle, then re-engage PTO drive.
IMPORTANT- Before folding for trans¬
port, disengage the PTO and wait for
blades to stop. Pull the latch chain to
allow complete folding, then release the
chain to lock decks in the raised posi¬
tion. These locks also serve the pur¬
pose of limiting the upward flex of the
cutter decks during operation. FOLD¬
ING THE DECKS WITH THE PTO’S EN¬
GAGED WILL DESTROY THE DRIVE
LINES!
Install pins into the transport lock positions.
(Figures 3-3 & 3-4) When implement is trans¬
ported on road or highway, day or night, use
tractor flashing warning lights unless prohibited
by law. The slow moving vehicle (SMV) sign
must be visible from the rear by approaching
vehicles.

TIPS ON MOWING WITH A MULCHER
The Locke Turf Mulch Pro is a turf maintenance mower with counter rotating blade sets de¬
signed to do a superior job of mulching grass clippings. To obtain the maximum effective¬
ness from your Mulch Pro the tips listed below should be followed:
Mow often - In general, mulching operations require more frequent mowing than
would conventional mowing procedures.
Watch your speed - Normal conditions will allow a speed of up to approximately 5
mph, but thick, heavy, damp conditions will require reduced ground speed.
Mow at 540 RPM to keep tip speed at its maximum.
Mow with a clean mower - Avoid grassy build-up under the deck.
Mow with sharp blades - A sharp blade cuts cleaner.
Wet grass will decrease distribution effectiveness and increase horsepower require¬
ments. Leaves, on the other hand, may be more effectively mulched when they are
slightly damp.
Mow at higher cutting heights - Remove and mulch no more than 2” - 2-1/2” of
grass length with each mowing. (Experts recommend not cutting off more than 1/3
of the grass blade length at any given time.)
Mow twice, at different height settings, (high, then low), if grass is extra tall.
Remember that horsepower requirements will vary with the mowing conditions such
as type and height of turf grass, moisture content, whether the terrain is flat or hilly,
etc.
The ideal cutting height may be different from other types of mowing equipment you
have used. Initially you should adjust your MP at least 1/2" higher than other types
of equipment. Use a trial and error method to determine if the MP should be ad¬
justed lower. Generally it is
best to begin high and work
Sha,p blades and a you way lower.

4-5 BLADE REPLACEMENT
A CAUTION A
WEAR HEAVY WORK GLOVES TO PROTECT
HANDS FROM SHARP EDGES. WHEN TURNING
BLADES, BE AWARE OF OPPOSITE BLADE AP¬
PROACHING.
A complete spare set of blades comes with the cutter.
The lower blades are pinned on the frame and the up¬
per blades are stored in the tool box. (Figure 4-4)
Always replace all (4) blades on an assembly to retain
balance. In addition to replacing blades when they
become worn and dull, they should also be replaced if
the uplift angle on the trailing side of the blade be¬
comes worn off. As the angle wears down, the mulch¬
ing action deteriorates.
D. Remove the four 3/8” x 1 ” capscrews and
Belleville washers from the upper mulching assembly.
Remove mulching assembly. The blade bushing will
come off with the mulching assembly.
E. Remove the 3/8” -24 UNF x 7/8” Gr. 8 blade
bolt and nut for each blade. Inspect the blade nut
shoulder and the blade bolts for wear. Replace if nec¬
essary.
F. When installing new blades on the mulching
assembly, make sure that two blades are installed on
the top side of the assembly 180° from each other and
two on the bottom side of the assembly. The blades
must mount on the rotation “pads” for proper operation.
Assemble the (4) new blades to the blade holder using
the blade nuts, bolts and flatwashers. Tighten the
bolts to 45 ft./lbs.
G. Insert the blade bushing in the center of the
mulching assembly so that the bushing flange is on the
top side of the assembly. Slide the mulching assembly
and flanged bushing over the spindle shaft and secure
mulching assembly to the upper blade carrier using the
(4) 3/8” - 16 UNC X 3/4" Gr. 5 bolts and Belleville
washers. Torque all (4) mulching assembly attach¬
ing bolts to 31 ft./lbs
FI. Install the blade washer over the spindle
shaft. Install the bottom blade and torque the 1/2" -
20 UNF Gr. 8 bolt to 76 ft./lbs. Note: The concave
side of the Belleville washer must be toward the
blades. Do not substitute with a flatwasher.
Figure 4-5 Blade Arrangement

A. Raise the cutter using the tractor hydraulic
system and use transport locks before changing
blades.
B. Turn off tractor, set parking brake and remove
key.
C. Remove bolt and Belleville washer securing
bottom blade to spindle. Remove blade. Shaft
washer will come off with the blade. (Figure 4-5)
