and mower, skip to “Shorten Driveline” on page 12.

All guards and shields must be installed and in good working

condition at all times during mower operation!

WARNING

Do not use a PTO adapter. A PTO adapter will increase strain

on the tractor’s PTO shaft resulting in possible damage to

shaft and driveline. It will also defeat the purpose of the

tractor’s master shield and could cause bodily injury or death.

WARNING

Always 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

Check Collapsible Length

Figure 1-4

WARNING

Do not over speed PTO or mower damage may result. Some

tractors are equipped with multispeed PTO ranges. Be certain

your tractor’s 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”

on page 23.

1. Make sure driveline is installed properly before

checking driveline collapsed length (Refer to

“Driveline Installation” instructions on page 1 1).

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

driveline shield as shown in Figure 1-4.

1. Park tractor and mower on a level surface. Slowly

engage tractor 3-Point lift lever to raise mower until

gearbox shaft is in line (level) with tractor PTO shaft.

a. If measurement is less than 1", shorten driveline.

a. If measurement is 1" or more, skip to “Check

Driveline Maximum Length” on page 12.

2. Support mower deck at this height with support jacks

or blocks to keep mower from drifting down.

6. Repeat steps 3 thru 5 for the remaining three gauge

wheels. Make certain all four gauge wheels are in the

same axle mounting hole (#1 or #2).

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:

Gauge Wheel Axle Adjustment

•

Front Wheel Cutting Height Adjustment

•

1. While holding one of the front gauge wheels up,

remove linchpin from gauge wheel spindle.

Rear Wheel Cutting Height Adjustment

•

3-Point Hitch Adjustments

•

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 thr u 5 for the other front gauge wheel.

NOTE: Tractor & mower should be on level ground.

7. See “Rear Wheel Cutting Height Adjustment” on

1. Align upper hitch with lower clevises as instructed in

Belt Tension

Refer to Figure 2-2:

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

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.

4. After mowing the first 50 feet, stop and check to see

that the mower is adjusted properly.

WARNING

5. Do not make sharp turns or attempt to back up while

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

only after following “Tractor Shut Down Procedure”

on page 16.

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 tractor’s PTO shaft resulting in possible damage to

shaft and driveline. It will also defeat the purpose of the

tractor’s 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 tractor’s 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.

7. S e e “Long Term Storage Instructions” on page 22

if mower is to be stored for a long time.

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.

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!

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.

3. Check blade balance by weighing both blades

individually. They should weigh the same with not

more than 1 1/2 oz. difference between the two

blades that make up a pair.

FRONT

4. Make an identifying mark on both blades to make

certain they are kept together as a matching pair.

Blade Installation

Refer to Figure 4-2 & Figure 4-4:

IMPORTANT: Always install blade with cutting edge

facing direction of rotation and wing tips pointing up.

1. Mount blade with wing tips pointing up towards

bottom of deck.

2. Reinstall blade (#5) to blade carrier (#1) with blade

bolt (#2) and hex slotted nut (#3). Do not tighten hex

slotted nut.

around the nut to keep cotter pin from falling out.

2. Disengage belt tension by loosening eyebolt (#1) and

removing spring (#2) from tension-chain (#3).

3. Remove old belt from pulleys and install new belt

around all six pulleys. Check to make certain belt is

properly positioned in all the pulley grooves.

4. Engage belt tension by hooking the tension spring

back onto the chain and tightening the eyebolt to the

proper tension. See “Belt Tension” on page 15 for

detailed tensioning instructions.

An illustration similar to Figure 4-4 is also illustrated on a

decal located on the deck under the center belt guard.

Section 4: Maintenance & Lubrication

Long Term Storage Instructions

Clean, inspect, service, and make necessary repairs to

the Grooming Mower when parking it for long periods and

when parking it at the end of a working season. This will

help ensure that the mower is ready for field use the next

time you hook-up to it.

WARNING

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!

1. Clean off any dirt or grease that may have

accumulated on the deck and moving parts. Scrape

off compacted dirt from the bottom of the deck and

then wash the surface thoroughly with a garden hose.

A coating of oil may also be applied to the lower deck

area to minimize oxidation.

2. Check blades and blade bolts for wear and replace if

necessary. See “Blade Inspection” on page 20.

3. Inspect mower for loose, damaged, or worn parts

and adjust or replace as needed.

4. Repaint parts where paint is worn or scratched to

prevent rust. Ask your Land Pride dealer for aerosol

touch-up paint. They are also available in touch-up

bottles with brush, quarts, and gallon sizes by adding

TU, QT, or GL to the end of the aerosol part number.
