Introduction
Introduction
Land Pride welcomes you to the growing family of new
product owners.
Owner Assistance
The Warranty Registration card should be filled out by the
dealer at the time of purchase. This information is
necessary to provide you with quality customer service.
This Disc Mower has been designed with care and built by
skilled workers using quality materials. Proper assembly,
maintenance, and safe operating practices will help you
get years of satisfactory use from the machine.
If customer service or repair parts are required contact a
Land Pride dealer. A dealer has trained personnel, repair
parts and equipment needed to service the disc mower.
Application
The Land Pride Disc Mowers are designed and built to cut
hay, grass, and other cultivated forage crops on farms,
ranches, set-aside acres, and vast right-of-ways. They
are adapted for 540 rpm three-point hitch Category 2
offset mounting and are Quick-Hitch adaptable. They are
compatible with 35 hp to 45 hp tractors equipped with live
or independent PTO’s. The DM3506 has 6 discs and a 96"
cutting width and the DM3507 has 7 discs a 112" cutting
width.
The parts on your disc mower have been specially
designed and should only be replaced with genuine Land
Pride parts. Therefore, should your disc mower require
replacement parts go to your Land Pride Dealer.
Serial Number Plate
For prompt service always use the serial number and mod-
el number when ordering parts from your Land Pride deal-
er. Be sure to include your serial and model numbers in
correspondence also. Refer to Figure 1 for the location of
your serial number plate.
Land Pride Disc Mowers will typically cut faster than
traditional sickle bar mowers and are designed to deliver
good cutting performance even in thick, tangled, and wet
grass conditions. Fire Ant hills and Gopher mounds, that
may tend to clog traditional Sickle-bar designs, will have
far less impact on our Rotary Cutter Bar design. Standard
replaceable rock guards provide cutter bar protection in
stony conditions and will greatly extend cutter bar life. A
standard break-away latch will release, allowing the cutter
bar to swing back, if an obstacle is hit.
Land Pride Disc Mowers are well suited for use in
agricultural regions where humidity and moisture
conditions are typically higher and the potential for crop
entanglement and tough ground conditions are present.
See “Features and Benefits”, “Section 5” for additional
information.

correctly.
!
CAUTION
Mowing Instructions
Do not disengage PTO when engine is at full PTO rpm. Always
idle engine before disengaging PTO.
NOTE: Although the mower is shielded to prevent
objects from being thrown by the blades, no one
shield is 100% effective. As a rule most people are
not knowledgeable of the dangers of being around a
disc mower while it is in operation. Therefore, the
operator should always stop mowing when someone
passes by.
IMPORTANT: ToSafety Break-Away avoid personal
injury, pick up all rocks and other debris before
mowing. Never assume an area is clear, so enter a
new area carefully. Cut material higher the first time
to allow the mower to clear unseen objects.
The break-away latch allows the cutter bar to swing back if
an obstruction is hit. If the latch releases, stop the tractor
immediately, idle engine and disengage the PTO.
!
WARNING
Prolonged exposure to high sound levels require hearing
protection. Wear hearing protection when operating this
machine with open platform tractors.
To reset the cutter bar, back the mower slowly and
carefully until breakaway latch repositions. The factory
setting of the latch is adapted to most working conditions.
Allow a few minutes for oil to spread in the cutter bar
before engaging the PTO when changing from transport to
operating position.
Check the cutter bar for any damage before resuming
operation.
If the cutter bar continues to break away after resetting,
the pressure of the spring assembly can be increased. In
all cases the length must not be less than 3 3/8 inch or
safety disengagement cannot function.
With the cutting bar on the ground, engage the PTO at low
tractor idle and accelerate gradually to 540 rpm PTO
speed.
If the cutter bar is operated at an angle for long periods of
time, hold it horizontal for a few minutes every half hour or
so of work to help lubricate gears at upper end of cutter
bar.
The stack of spring washers should be compressed to
3 3/8 inch. See Figure 3-5.
3 3/8”
Adapt forward speed to working conditions. Gear down
when mowing in dense crops. Do not lower tractor rpm.
Adverse Field Conditions
!
DANGER
Do not use machine in rocky or stony conditions.
Extra care and precaution should be taken in rough or
debris-ridden fields. The following adjustments should be
made to the mower in these conditions to minimize the
possibility of foreign objects being deflected by the cutting
blades.

Section 2 Operating
If you do hit an object when you are mowing, immediately
disengage the PTO, idle the engine, stop the tractor, wait
for all moving parts to come to a complete stop, shut off
the tractor, set the brake, remove the keys, and inspect for
damage. If damage is present, make the necessary
repairs. If no damage is present, but you have tripped the
"Break Away Safety Latch, slowly reverse the tractor until
the latch resets and proceed with mowing operations.
Operating Instructions
By now you should have thoroughly read your Disc Mower
Operator’s Manual, properly attached your Land Pride
Disc Mower to your tractor, and reviewed the Operating
Checklist. If you have not yet completed all of these
functions, please do so now.
Now that you’re properly briefed and your disc mower is
ready, it’s time to transport to the field.
Prior to actually beginning cutting operations, you will
want to get the mower up to full 540 rpm PTO speed by
engaging the PTO with the tractor engine at idle and
gradually increasing engine rpm to PTO speed. Once you
reach the full 540 rpm, allow the mower to run for a few
minutes at level position so the oil in the cutter bar can
lubricate all internal moving parts. You will also want to
take this opportunity to make a quick Operational Running
Check. Listen and visually inspect for any component or
part that may be loose or out of adjustment. Don’t be
alarmed by the noise level of the free running Disc Mower.
It will actually become quieter when you begin mowing
and have some run in time on it.
For transport purposes, your Disc Mower should be
securely locked with the cutter bar in the upright or vertical
position. Make sure the support leg is in the high position.
A "Slow Moving Vehicle" sign should be in place and
visible from the rear, if you are using a public road or
right-of-way. Select a safe speed and transport to your
cutting site in such manor that faster moving vehicles can
pass you safely.
Once you have safely arrived at your hay field, position
your tractor on level ground. Make sure that no one is
within 20ft of the mower, as your prepare to lower the
cutter bar from transport to working position. Lower the
three-point hitch to a point where the inboard end of the
cutter bar is approximately 12" off of the ground. Retract
your lift cylinder and pull on the latch cord to release the
transport or road-latch mechanism. Using your lift cylinder
control lever, slowly lower the cutter bar until the outer end
touches the ground. Adjust the three-point hitch to
"working position" where the driveline is horizontal with
the ground and lock the three-point hitch control lever in
place. Extend the lift cylinder until there is 1" of clearance
over the reach arm. Install the stroke control to the tarp
frame cushion spring rod and re-situate the tarp into
proper position. Your Disc mower is now in working
position.
If your Operational Running Check was ok, begin mowing
operations by opening up the lands on your field. Make
enough lands so you can easily make your turns to
properly line up for each pass down the field. If your tractor
and Disc Mower are set up right, you should be able to
straddle the previous swath as you make each
subsequent pass starting in the center of the field. If you
do experience cutting problems, refer to the "Trouble
Shooting" section of your Operator’s Manual for corrective
action.
When your done mowing for the day and need to transport
the mower to your storage site, simply reverse the process
you used to take the mower out of transport mode. When
you are done mowing for the season, clean and lubricate
your mower, replace warn or missing parts, release
tension on the belts, and store the unit with the cutter bar
in the horizontal working position. You will get longer
service life out of your mower by storing it inside and
repainting scratched or rusted components.
Controlling or setting your cutting height is accomplished
by adjusting the "top link" on you three-point hitch.
Extending or lengthening the top link will raise your cutting
height, while shortening the top link will lower the cutting
height. If you are cutting in an area you are not familiar
with or believe there might be rocks or debris present, you
must raise the cutting height accordingly. This will reduce
the potential of personal injury and or damage to the
machine. Shut the mower down immediately if someone
approaches in a vehicle or on foot.
With a little practice and experience you should become
very good at operating your Land Pride Disc Mower.

DANGER
Before making any adjustments to this machine, disengage
PTO, shut off tractor, remove ignition key and wait for all
moving parts to stop. Disconnect the PTO driveline.
Always retighten or check belt after 4-8 hours of operation.
Refer to Figure 2-2.
1. Loosen u-bolt (#1).
Leveling for Transport and Operation
The elevating arm and retaining arm need to be adjusted
together. See Figure 2-1.
2. Tighten nut (#2) on the belt tension rod (#3) until you
have a 3/4” deflection midpoint between pulleys. Refer
to Figure 2-3.
3. Retighten nut on u-bolt.
Belt Tension Adjustment
Belt must be properly tensioned at all times to avoid
excessive flopping and slipping. Loose belt will also cause
poor cutting and premature wear.

Cutting Height
Refer to Figure 2-4:
Cutting height can be adjusted with the upper 3-point hitch
link.
To minimize blade and disc wear, improve grass regrowth
and get maximum nutritive value from the crop, minimum
cutting height should never be adjusted less than 1 1/4“.
Maximum cutting height of 2” is achieved when the discs
are parallel to the ground. Adjustment of cutting height is
achieved by altering the cutter bar tilt angle. This is done

Section 4 Maintenance and Lubrication
General Maintenance
Proper servicing and adjustment is the key to the long life
of any farm implement. With careful and systematic
inspection, you can avoid costly maintenance, time and
repair.
!
CAUTION
When changing blades, always replace the blade bolt & blade
nut together at the same time. Worn or damaged blade bolts or
nuts could fail in a hazardous manner that could cause injury.
Blade Replacement
!
1. See Figure 5-1a. New blades are 1 3/4” wide. Blades
should be replaced when they are worn to about
1 5/16” (B) wide at a distance of 3/8” from the disk. The
length (A) of the blade should be greater than 2 1/2”.
DANGER
Before servicing this machine, turn off the tractor engine,
remove the ignition key and disconnect the PTO driveline.
Each new machine should be checked after the first 10
hours of work. All screws and bolt torques should be
routinely checked.
2. See Figure 5-1b. Replace blades if the hole for the
securing bolt has become oval 3/32” more than the
diameter of the original hole.
At the beginning of each season:
1. Check and/or change the oil; lubricate or grease all
points. See Lubrication in this section.
2. Check blade wear and condition of their fasteners, see
3. Check wear on guards and curtain.
4. Retention belts, see “Belt Tensioning Adjustment”,
5. Check all screws and bolts to be sure they are tight.
Servicing Blades
Cutting quality as well as safe operation depend on the
regular inspection and care given to the knives.

WARNING
To avoid personal injury when the blades and/or carrier are
being serviced, always block the mower up to prevent it from
falling.
Fastener Replacement
Check blades for cracks and wear and blade bolts for
tightness daily. Blades should be replaced when they are
worn excessively, bent, nicked, deformed, or out of
balance.
NOTE: Always replace blade bolts and nuts when
they have been removed 5 times.
1. Replace fasteners when a visible deformation is
found.
NOTE: Blade bolts should be tightened to 55 ft-lb
torque.
2. See Figure 5-2a. Replace bolts when wear on the bolt
head reaches the contact area of the blade.
3. Replace bolts when the flat sides at the bolt flange are
excessively worn or missing altogether.
NOTE: Always replace damaged blades. Never
straighten a bent blade. Never replace one knife only
per disc. Always replace both of them to avoid
creating an out-of-balance force.
4. See Figure 5-2b. Replace bolts when the diameter (D)
of the bolt shoulder is less than 5/8”.
5. See Figure 5-2c. Replace nuts when the height (H) of
the nut less is than half of the original height of 5/16”.
6. Replace Belleville washers on breakaway if they are
flattened.
!
CAUTION
Replace with Land Pride blades only. Substitute blades may not
meet specifications and may fail in a hazardous manner that
could cause injury.
