Do not over speed PTO or mower damage may result. Some  
tractors are equipped with multispeed PTO ranges. Be certain  
your tractors PTO is set for 540 rpm.  
Check Driveline Collapsible Length  
Refer to Figure 1-4:  
IMPORTANT: An additional driveline may be  
required if mower is to be used on more than one  
tractor, especially if a Quick Hitch is used.  
IMPORTANT: A driveline that is too long can bottom  
out causing structural damage to tractor and mower.  
Always check driveline collapsed 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: The driveline must be lubricated  
before putting it into service. Refer to “Lubrication”  
1. Make sure driveline is installed properly before  
checking driveline collapsed length (Refer to  
IMPORTANT: The tractor’s PTO shaft and mower  
gearbox shaft must be aligned and level with each  
other during installation of driveline. This alignment  
is the shortest distance between the two shafts.  
2. With driveline level, measure 1" (“B” dimension)  
back from universal joint shield to end of outer

CAUTION  
Wear a pair of gloves when checking cutting height. Avoid  
direct contact with cutting edge of blade.  
Front Wheel Cutting Height Adjustment  
Refer to Figure 2-1  
Seven spacers are provided for each gauge wheel. Two  
spacers are 1/4" thick, two are 1/2" thick, and three are 1"  
thick. With mower still supported on blocks, reposition  
spacers on the front gauge wheels as follows:  
There are 4 primary adjustments that should be made  
prior to actual field operations:  
1. While holding one of the front gauge wheels up,  
remove linchpin from gauge wheel spindle.  
2. Positioning all spacers above the spindle tube allows  
for a minimum cutting height of 1" with gauge wheels  
mounted in axle hole (#1) and 2" minimum cutting  
height when gauge wheels are mounted in axle  
hole (#2).  
Proper adjustment of each of these items will provide for  
higher efficiency, improved cutting performance and  
longer blade life.  
Gauge Wheel Axle Adjustment  
3. Determine a cutting height in 1/4" increments and  
subtract the 1" or 2" minimum cutting height from the  
determined cutting height.  
Refer to Figure 2-1 on page 14:  
Two gauge wheel axle holes (#1 & #2) are provided in  
each gauge wheel yoke. If gauge wheels are mounted in  
the upper axle holes (#1), cutting height ranges from  
1" to 5 1/2". If gauge wheels are mounted in the lower  
axle holes (#2), cutting height ranges from 2" to 6 1/2".  
Readjust gauge wheel axles as follows:  
4. Move enough spacers from above the spindle tube to  
below the spindle tube to equal the calculated  
subtracted height in step 3 above.  
5. Secure gauge wheel and spacers with linchpin.  
6. Repeat steps a thru 5 for the other front gauge wheel.  
NOTE: Tractor & mower should be on level ground.  
1. Align upper hitch with lower clevises as instructed in

With mower still supported on blocks, reposition spacers  
on the rear gauge wheels as follows:  
!
WARNING  
1. While holding one of the rear gauge wheels up,  
remove linchpin from gauge wheel spindle.  
Excessive belt tension can lead to premature damage/  
breakage of belt and drive component and is a safety hazard  
to operator and bystanders.  
2. Move the same thickness and number of spacers as  
was moved for the front gauge wheels plus up to one  
more 1/4" or 1/2" thick spacer from above to below  
the gauge wheel spindle tube.  
!
CAUTION  
Belt drive system is under spring tension; use care to avoid  
bodily harm while making adjustments to the belt!  
3. Repeat steps 1 thru 2 for the other gauge wheel.  
4. Slowly lower mower until gauge wheels touch the  
ground and mower hitch clevises are level with the  
ground. If not already done, set tractor 3-Point control  
lever stop at this height and in float position.  
IMPORTANT: Excessive belt tension can damage  
the belt and drive components prematurely and is a  
safety hazard to the operator and bystanders. Not  
enough tension can result in excessive belt slippage  
causing premature belt damage.  
5. Set park brake, turn off tractor, and remove key.  
6. With a rag or thick padded glove, rotate blades  
parallel to direction of travel.  
1. To check belt tension, apply force at arrow A with a  
tension tester until the belt has deflected 1/4 of an  
inch. This force should range from 7 to 10 lbs. on the  
tension tester.  
7. Measure distances from front blade tip and rear  
blade tip to ground. The rear blade tip should be  
equal to or slightly higher than the front blade tip but  
not by more than 1/2". Never should the rear blade tip  
be lower than the front blade tip.  
2. To increase or decrease belt tension, adjust  
eyebolt (#1) as needed until belt tension is from  
7 to 10 lbs.  
8. Adjust rear gauge wheels up or down an equal  
amount to change height of rear blade.  
3. If more belt tension is required than the eyebolt can  
adjust, then loosen the eye bolt until all tension on  
spring (#2) is removed and reattach spring (#2) in the  
next chain link (#3) closer to the eyebolt.  
3-Point Hitch Adjustments  
Refer to Figure 2-1 on page 14:  
The 3-Point hitch system on this mower has been  
designed for front to back flotation when mowing on  
uneven terrain. This is done by adjusting the length of the  
tractor’s top center link until the upper hitch pin is  
vertically above the lower hitch pin. See “Top Center

Section 3: Operating Instructions  
1. Clear the area to be mowed of rocks, branches, and  
other foreign objects that might be picked up and  
thrown by the mower blades. Mark any potential  
hazards that can’t be cleared.  
!
DANGER  
Do not use mower blades for a fan. Mower blades are not  
properly designed or guarded for this use. Using mower  
blades as a fan can result in serious injury and/or death.  
2. Lower mower to ground. Set tractor throttle at idle.  
Engage PTO to start blades rotating. Increase  
throttle to 540 PTO rpm.  
!
WARNING  
3. At first, begin mowing in a low gear and shift up until  
the desired speed is achieved - always maintain  
540 PTO rpm regardless of gear selection. Mower  
blades will cut better at a faster blade speed than at  
reduced throttle.  
Use Grooming Mower for its intended purpose only. Do not  
use mower to lift or carry objects; to pull fence posts, stumps,  
or other objects; or to tow other equipment. Doing so can  
damage the mower, cause serious bodily injury, or death.

mower is on the ground.  
6. Do not engage PTO with mower in the fully raised  
position. Do not engage or disengage PTO at full  
throttle.  
!
WARNING  
7. Grass is best cut when it is dry. Mowing wet grass  
can cause plugging resulting in grass clumps behind  
the mower.  
Do not operate mower with loose pins, bolts and nuts. Loose  
hardware can cause the mower to not preform properly and  
may lead to breakage that can cause bodily injury or death.  
8. Grass should be mowed frequently as shorter  
clippings deteriorate faster.  
!
WARNING  
9. If mowing extremely tall grass, it is best to raise  
cutting height and mow the area, then lower cutting  
height and mow a second time at the desired height.  
Always make certain driveline yokes are secured to the tractor  
PTO shaft and mower drive shaft before engaging PTO. A  
loose driveline can slips off the end of a connected shaft while  
rotating and cause serious bodily injury or death.  
10. Periodically check for foreign objects wrapped  
around the mower blades. Remove foreign objects  
!
WARNING  
11. Frequently inspect the mower for loose bolts and  
nuts. Tighten all loose bolts and nuts as indicated in  
the “Torque Values Chart” on page 28.  
Do not use a PTO adapter. A PTO adapter will increase strain  
on the tractors PTO shaft resulting in possible damage to  
shaft and driveline. It will also defeat the purpose of the  
tractors master shield and could cause bodily injury or death.  
!
WARNING  
Do not over speed PTO or mower damage may result. Some  
tractors are equipped with multispeed PTO ranges. Be certain  
your tractors PTO is set for 540 rpm.

Section 3: Operating Instructions  
General Operating Instructions  
Unhooking the Mower  
By now you should have thoroughly read your Grooming  
Mower Operator’s Manual, properly attached your Land  
Pride FDR3690 to your tractor, and reviewed the  
operating checklist. You should have also inspected the  
area where you intend to mow and cleared it of safety  
hazards and foreign objects. If you have not yet  
completed all of these functions, it is an absolute must  
that you do so now before proceeding.  
The following steps should be done when unhooking the  
Grooming Mower from the tractor.  
1. Park on a level solid surface.  
2. Shut tractor engine off and engage parking brake.  
3. Lower mower to the ground and chock front and back  
side of wheels to keep mower from moving.  
4. Follow all tractor shut down procedures outlined on  
page 16 before dismounting from the tractor.  
Now that you are properly briefed and prepared, its time  
to start the tractor and move to your starting point. When  
transporting to your mowing site, select a safe ground  
transport speed. When traveling on roadways, transport  
in such a manner that faster moving vehicles can easily  
see you and pass you safely. When travelling over rough  
and hilly terrain, reduce your speed and avoid quick or  
sharp steering corrections. Take extra care to ensure that  
the mower doesn’t come into contact with obstacles such  
as trees, buildings, or fences.  
5. Unhook 3-Point hitch from tractor. Reinstall hitch  
pins, linchpins, and hairpin cotters in cutter hitch.  
Refer to Figure 3-1:  
6. Rotate upper hitch (#1) up and store driveline (#3) in  
driveline hanger (#2) to keep dirt out of its u-joints.  
When you have arrived at the mowing site, start the  
tractor, raise the deck to make sure that everything is  
properly attached and that the driveline is not in a bind or  
in contact with the mounting frame. Also make sure the  
tractor tires aren’t in contact with the deck. With the deck  
still in the raised position, proceed to your starting point  
and lower your deck to the ground in mowing position.  
Reduce your tractor engine rpm to idle and engage PTO.  
Gradually raise tractor engine rpm to achieve the  
540-rpm PTO speed. Now begin mowing at a ground  
speed of approximately 4-5 mph.  
The proper mowing speed will ultimately be determined  
by ground conditions, desired finish, common sense, and  
good safe mowing practices by the operator.  
Grass is best cut when it is dry. Mowing in wet grass can  
cause plugging resulting in grass clumps behind the  
mower. Grass should be mowed frequently as shorter  
clippings deteriorate faster. When mowing in tall grass it  
is best to raise the cutting height, mow the area, then  
lower the cutting height, and mow a second time.  
33509  
Driveline Storage  
Figure 3-1  
After mowing approximately 50 ft., stop the tractor,  
disengage the PTO, set the brake, turn off the engine,  
remove the key, and dismount the tractor to see if the  
mower is adjusted properly. If you need to dismount the  
tractor on a hill or incline to inspect, adjust, or park the  
mower for any reason, place wheel chocks under the rear  
tires for added safety. Once you have made necessary  
adjustments, you may continue mowing. Do not engage  
the PTO at high engine rpm and avoid making sharp  
turns if at all possible. If anyone approaches while you  
are mowing, disengage the PTO and stop the tractor.  
With a little practice and experience you will become very  
good at operating your Land Pride FDR3690 Rear  
Discharge Grooming Mower. Always remember that  
there is no substitute for proper maintenance and good  
safe operating practices. See “Features and Benefits”  
section or “Product Specifications” for additional  
information and performance enhancing options.

Section 4: Maintenance & Lubrication  
Maintenance  
Blade Inspection  
Proper servicing and adjustments are key to the long life  
of any implement. With careful inspection and routine  
maintenance, you can avoid costly downtime and repair.  
Refer to Figure 4-1:  
Always inspect cutting blades before each use. Make  
certain they are properly installed and in good working  
condition. Replace any blade that is damaged, worn,  
bent, or excessively nicked. Never try to straighten a bent  
blade! Small nicks can be ground out when sharpening.  
Check all bolts and pins after using the unit for several  
hours and on a regular basis thereafter to ensure they are  
tight and secured. Lubricate components on schedule.  
Replace worn, damaged or illegible safety labels by  
obtaining new labels from your Land Pride dealer.  
!
DANGER  
Always secure mower in the up position with solid supports  
before servicing underside of mower. Never work under  
equipment supported by hydraulics. Hydraulics can drop  
equipment if controls are actuated or if hydraulic lines burst.  
Either situation can drop the mower instantly even when  
power to the hydraulics is shut off.  
!
DANGER  
Perform maintenance only on a mower that is not running.  
Disengage PTO, place tractor in park or set park brake, shut  
tractor engine off, remove switch key, and wait for blades to  
come to a complete stop before dismounting from tractor to  
perform maintenance!

Inspection of Blades & Sharpening  
Figure 4-1  
!
DANGER  
All V-belt guards must be in good working condition and  
installed before PTO is engaged. Never allow fingers, hands,  
or other body extremities to come near a moving V-belt or  
pulley. Doing so can result in server bodily injury or death.  
!
DANGER  
Bent, Deformed or Split Blades should be removed from unit  
and discarded. Never weld a broken or cracked blade. DO  
NOT attempt to straighten to reuse such blades. ALWAYS  
replace with a new Land Pride blade to assure safety.  
!
WARNING  
Frequently check all hardware to make certain it is tight and  
not broken or missing. Such hardware can cause the mower to  
not preform properly and may lead to breakage that can cause  
bodily injury or death.  
!
WARNING  
DO NOT attempt to modify a blade, such as hard surfacing,  
heat or cold treating, or by any other method.  
1. Check blades for wear. Blade performance will be  
reduced as blades wear and are resharpened.  
!
WARNING  
2. Check blades to see if they are bent, deformed, or  
split. DO NOT attempt to straighten or weld blades for  
reuse. They should be removed and discarded.  
Replace worn, damaged, or missing parts only with genuine  
Land Pride Parts. Replacing parts with other brands can  
cause the equipment to not perform properly and may lead to  
breakage that can cause bodily injury or death.  
3. If the blade cutting edge is dull or nicked, it should be  
sharpened or replaced if worn out.  
Blade Removal  
!
CAUTION  
Refer to Figure 4-2 on page 21:  
Do not alter Land Pride equipment or replace parts with other  
brands. Doing so can cause equipment to perform improperly  
and may lead to breakage that can cause bodily injury.  
Replace parts only with genuine Land Pride parts.  
Remove cutting blades to sharpen or replace as follows:  
1. Place tractor gear selector in park, set park brake,  
disengage PTO if operating, shut engine off, remove  
switch key and wait for blades to come to a complete  
stop before dismounting from tractor.  
!
CAUTION  
ALWAYS wear eye protection and gloves while inspecting,  
removing, sharpening, and replacing mower blades.  
2. Disconnect main driveline from tractor PTO and  
secure cutter deck in the up position with solid  
supports before servicing underside of mower.

IMPORTANT: Replace mower blades in pairs with  
genuine Land Pride blades only. Not replacing both  
blades will result in an out-of-balance condition.  
33511  
Sharpen blades in pairs. Do not remove any more  
material than necessary. Paired blades should weigh  
within 1 1/2 oz. of each other.  
Out-of-balance blades will contribute to bearing  
damage and structural cracks in the mower housing.  
1. Clean blade and mounting surface of all debris  
before sharpening or replacing the blades.  
2. See Figure 4-3: Grind cutting edge at the same bevel  
as the original and sharpen only the top of the cutting  
edge to maintain sharpness.  
Blade Sharpening
