SAFETY RULES
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOL VED!
Safety is a primary concern in the design and
manufacture of our products. Unfortunately, our
efforts to provide safe equipment can be wiped
out by an operator’s single careless act.
In addition to the design and configuration of
equipment, hazard control and accident prevention are dependent upon the awareness, concern,judgement,and propertrainingofpersonnel
involved inthe operation,transport, maintenance
and storage of equipment.
It has been said “The best safety device is an
informed,careful operator.” We ask you tobethat
kind of operator.
TRAINING
! Safety instructions are important! Read all attachment and power unit manuals; follow all safety
rules and safety decal information. (Replacement
manuals are available from dealer or, in the United
States and Canada, call 1-800-319-6637.) Failure to
follow instructions or safety rules can result in
serious injury or death.
! Know your controls and how to stop engine
and attachment quickly in an emergency.
! If you donot understand any partofthis manu al and need assistance, see your dealer.
! Operators must be instructed in and be capable of the safe operation of the equipment, its
attachmentsand allcontrols. Do not allow anyone
to operate this equipment without proper instructions.
! Never allow children or untrained persons to
operate equipment.
PREPARATION
! Check that all hardware is properly installed.

! Make sure spring-activated locking pin or
collar slides freely and is seated firmly in tractor
PTO spline groove.
! Make sure driveline shield tether chains are
attached tothe tractorand equipmentas
instructed. Replace if damaged or broken and
check that driveline guards rotate freely on driveline before operating equipment.
! Before starting tractor, check all equipment
driveline guards for damage and make sure they rotate freely on all drivelines. Replace any damaged
guards. If guards do not rotate freely on drivelines,
repair and replace bearings before operating.
! Power unit must be equipped with ROPS or
ROPS CAB and seat belt. Keep seat belt securely
fastened. Falling off power unit can result in death

To raise front of mower, move spacers under front
caster wheel arms.
Remember, measurement at location “A” Figure 4
should not be less than location “B” and should not be
over 1/2” greater than location “B.”
Tractor Top Link Adjustment (Figure 6)
Adjust tractor top link so mower is level at 16” between
caster wheel and ground (dimension “C” Figure 6).
This will allow the mower to follow ground contour.
Front Caster Arm Configuration
for RD6000 & RD7200 Only (Figure 5)
The RD6000 and RD7200 front casters can be set in
two positions. This is accomplished using right and
left offset caster arms. The figure shows a right offset
assembly. The direction of the offset is defined by
looking from the mounting hole “A” towards the pivot
tube “B.” The pivot tube should be higher than the
mounting holes. When viewing the arm in this way, the
direction of the offset can be determined.

Figure 5 shows thetwo possibleconfigurations for the
RD6000 and RD7200 front caster arms. The inner
position allows the outside edge of the mower to be
used for trimming under items such as shrubs or
fences. The outer position provides the most clearance for rear tractor tire interference. To change
configurations, remove the cap screws and nuts and
move the arms from one side of the machine to the
other. Secure with hardware.
The rear caster arms should be mounted as shown.
The RD8400 front caster arms are fixed and cannot
be changed.
Front Caster Wheel Interference Check
(Figure 6)
IMPORTANT
! Do notoperate tractorand mower until
this interference check has been performed. If you change tractors, you must
perform the check for that mounting.
Perform this check with all of the spacers and springs
above the caster wheel arm. This will place the caster
wheels intheir highest position and provide the lowest
cutting height for the mower.
Raise mower with tractor hydraulics to 16” at
dimension “C” or maximum height of tractor lift,
whichever is less.
Pivot both front caster wheels forward and check that
there is clearance between caster wheels and tractor
tires.

Front Roller (Optional)
The caster wheels and side skids effectively reduce
scalping in most cases. However ,you may encounter
areas where the caster wheels and/orside skids drop
into depressions and allow center of mower tocontact
ground and scalp. An optional front roller may be
installed to minimize scalping.

Operating Technique
Should mower become plugged, causing belt to slip
for over two seconds, maneuver equipment into a
previously cut area and allow mower to clear
accumulated material. Continue running at least two
minutes, allowing pulleys to cool. Stopping the mower
in contact witha very hot pulley willbake and ruin belt.
CAUTION
! Stoptractorandimplementimmediately upon striking an obstruction. Turn off
engine, remove key, inspect and repairany
damage before resuming operation.
Proper groundspeed will depend upon theterrain, the
height, type and density of material to be cut.
Normally, ground speed will range from two to five
mph. Talldense material should be cut at alow speed;
thin medium-height material can be cut at a faster
ground speed.
Always operate tractor PTO at 540 rpm. This is
necessary to maintain proper blade speed and
produce a clean cut.
Under certain conditions, tractor tires may roll some
grass down and prevent it from being cut at the same
height as the surrounding area. When this occurs, reduce your ground speed, but maintain PTO at 540
rpm. The lower ground speed will permit grass to at
least partially rebound.
In general, lower cutting heights give a more even cut
with less tendency to leave tire tracks. However, it is
better to cut grass frequently rather than too short.
Short grass deteriorates rapidly in hot weather andinvites weed growth during growing seasons. Follow
local recommendations for the suitable cutting height
in your area.
Tips
W ARNING
! Inspect and clear area of stones,
branches or other hard objects that might
be thrown, causing injury or damage.
Extremely tallmaterial should be cut twice. Setmower
at a higher cutting height for the first pass. Then cut
at desired height, at 90° to the first pass.
Remember, sharp blades produce cleaner cuts and
require less power.
Analyze area to be cut to determine the best
procedure. Consider height and type of grass and
terrain type: hilly, level or rough.
Power for operating mower is supplied by tractor
PTO. Operate PTO at 540 rpm. Know how to stop
tractor and mower quickly in case of an emergency.
Plan your mowing pattern to travel straight forward
whenever possible. Mow with uncut grass to theright.
This will distribute the clippings over the cut area.

Uneven Terrain
W ARNING
! Do not operate on steep slopes.
! Do not stop, start or change directions
suddenly on slopes.
! Use extreme care and reduce ground
speed on slopes and rough terrain.
! Watch for hidden hazards on the ter-
rain during operation.
Pass diagonally through sharp dips and avoid sharp
drops to prevent “hanging up” tractor and mower.
Practice will improve your skills in maneuvering rough
terrain.
Removing Mower from Tractor
(Figure 7)
Disengage tractor PTO, raise mower with 3-point hitch.
Collapse driveshaft as far as possible and store it in
PTO hanger bracket to prevent ground contact. Place
blocks under mower side skids. Lower mower onto
blocks, disconnect mower from tractor 3-point hitch,
and carefully drive tractor away from mower.

OWNER SERVICE
Safety is a primary concern in the design and
manufacture of our products. Unfortunately, our
efforts to provide safe equipment can be wiped
out by an operator’s single careless act.
In addition to the design and configuration of
equipment, hazard control and accident prevention are dependent upon the awareness, concern,judgement,and propertrainingofpersonnel
involved inthe operation,transport, maintenance
and storage of equipment.
It has been said “The best safety device is an
informed,careful operator.” We ask you tobethat
kind of operator.
The information in this section is written for operators
who possess basic mechanical skills. Should you
need help, your dealerhas trainedservice technicians
available. For your protection, read and follow all
safety information in this manual.
W ARNING
! Never allow children or untrained per-
sons to operate equipment.
BLOCKING METHOD
(Figure 8)
Do not work underneath mower unless it is properly
attached to the tractor and blocked securely. When
properly attached, the unit will be anchored to
minimize front to rear movement.
Raise mower completely, set tractor brakes, turn
engine off, remove key, block tractor wheels front and
rear, and disconnect mower driveline from tractor.
The only approved blocking device for this mower is
a jackstand with a load rating of1000 pounds or more.
One jackstand under each corner of the mower (four
total) must be installed before working underneath
this unit.
Install jackstands under each corner of the mower.
When blocking, you must consider overall stability of
the unit. Just blocking under the unit will not ensure
your safety. The working surface must be level and
solid to support the loaded weight of the jackstands.
Test jackstands stability before working under any
portion of the mower.
! Keep bystanders away from equip-
ment.
! Before working underneath, carefully
read operator manual instructions, discon-
nect driveline, raise mower, securely block
up all corners with jackstands and check
stability. Secure blocking prevents equip-
ment dropping from hydraulic leak down,
hydraulic system failures, or mechanical
component failures.
! Keep all persons away from operator
control area while performing adjust-
ments, service or maintenance.
! Make sure spring-activated locking
pin or collar slides freely and is seated
firmly in tractor PTO spline groove.
! Operate tractor PTO at RPM speed
stated in “Specifications” section.
CAUTION
! Always wear relatively tight and belted
clothing to avoid entanglement in moving
parts. Wear sturdy, rough-soled work
shoes and protective equipment for eyes,
hair, hands, hearing and head.

LUBRICATION INFORMATION
(Figure 9)
Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
Figure 9 shows the lubrication points. The accompanying chart gives the frequency of lubrication in operating
hours, based on normal operating conditions. Severe or
unusual conditions may require more frequent lubrication. Some reference numbers have more than one
location; be sure you lubricate all locations.
CD4985VAR
PN-52886 (4/97)14
Page 17
Use a lithium grease of #2 consistency with a MOLY
(molybdenum disulfide) additive for all locations. Be
sure to clean fittings thoroughly before attaching
grease gun.When appliedaccording to the lubrication
chart, one good pump of most guns is sufficient.
Overfilling the gearbox will cause the excess gear
lube to blow out vent plug. The gear lube could then
ruin the belt.
Driveshaft Lubrication
Use SAE 90W gear lube in the gearbox. Oil level is to
be up to plug on side of gearbox. See Figure 9.
Check gearbox daily for evidence of leakage at both
seals and the gasket between the housing and cover.
If leakage is noted, repair immediately. There may be
a small amount of lubeemitted from thevent plug; this
is not considered leakage.

8
Lubricate the driveshaft slip joint every 8 operating
hours. Failure to maintain proper lubrication could
result in damage to U-joints, gearbox and driveshaft.
Lower mower to ground.
Apply grease at three locations as shown in Figure 9.
Raise and lower mower several times to distribute
grease.

operate valve levers to release any hydraulicpressure, set parkingbrake,stop engine,
remove key, and unfasten seat belt.
! Keep all persons away from operator
control area while performing adjustments, service or maintenance.
Figure 10. Belt Routing
One of the major causes of belt failure is improper
installation. Before a new belt is installed, check
pulley shafts and bearings for wear. Check pulley
grooves for cleanliness. Make sure spindles turn
freely andwithout wobble.If grooves require cleaning,
moisten a cloth with a non-flammable, non-toxic
degreasing agent or commercial detergent and water.
Avoid excessive force during installation. Do not use
tools topry belt into pulley groove. Do not roll belt over
pulleys to install. This can cause hidden damage and
premature belt failure.
IMPORTANT
! Use care when installing or removing
belt from spring-loaded idler at step 5.
Springs store energy when extended and,
if released suddenly, can cause personal
injury.

GEARBOX MAINTENANCE
(Figure 18)
Read this entire section before starting any repair.
Many steps are dependent on each other.
Fill gearbox with SAE 80W or 90W gear lube until it
runs out the side level plug (18).
Repair to this gearbox is limited to replacing bearings,
seals and gaskets. Replacing gears, shafts and a
housing is not cost effective. It is more economical to
purchase a complete gearbox if repair other than
replacing bearings, seals or gaskets is required.
Inspect gearbox for leakage and bad bearings.
Leakage is a very serious problem and must be
corrected immediately.
Bearing failure is indicated by excessive noise and
side to side or end play in gear shafts.
(Rev. 2/9/99)

Page 23
Leakage Repair
Recommended sealant for gearbox repair is Permatex Aviation 3D Form-A-Gasket
or equivalent.
Leakage can occur at the vertical or horizontal
gaskets and shaft seals. Leakage at the horizontal
gasket or seal can be repaired without removing the
gearbox from the cutter.
Horizontal Shaft Leak Repair

any burrs or nicks with emery cloth.
Place seal (spring-loaded lip toward housing) squarely on cap. Select a piece of pipe or tubing with an OD
that will set on outside edge of seal but will clear the
housing. Tubing with an OD that is too small will bow
seal cage and ruin seal.
Lubricate gear shaft and seal lips.
Carefully press seal into housing, preventing distor-
tion to the metal seal cage. Vertical seal should be
recessed 0.275” inhousing. Horizontal sealshould be
pressed flush with outside of housing.

DIM “A”
Invert gear stand.
When gear stand is installed onmower, dimension “A”
(from the top of the mower deck to the centerline of
the drive pulley) must be 2-7/16” (plus or minus
1/32”). This is a critical dimension and must be
carefully adjusted for proper belt life. Add or subtract
shim washers under idler pulley to align with drive
pulley.
Tighten gear stand hardware.
Fill gearbox half full of SAE 90W gear lube. Check
level after waiting five minutes to permit lube to work
through bearings and add lube, if necessary, until it is
half full.
Replace driveline shield. Attach driveline to gearbox.

ASSEMBLY INSTRUCTIONS
CAUTION
! Always wear relatively tight and belted
clothing to avoid entanglement in moving
parts. Wear sturdy, rough-soled work
shoes and protective equipment for eyes,
hair, hands, hearing and head.
W ARNING
! Before working underneath, carefully
read operator manual instructions, disconnect driveline, raise mower, securely block
up all corners with jackstands and check
stability. Secure blocking prevents equipment dropping from hydraulic leak down,
hydraulic system failures, or mechanical
component failures.
Assembly of the mower is the responsibility of the
WOODS dealer. It should be delivered to the owner
completely assembled, lubricated and adjusted for
normal conditions. Complete the following check lists
when assembly is complete.
The mower is shipped partially assembled. Assembly
will be easier if components are aligned and loosely
assembled before tightening hardware. Recommended torque values for hardware are located on
page 3. All bolts are grade 5 unless specified otherwise.
Select a suitableworking area. Open parts boxes and
lay out parts and hardware to make location easy.
Refer to illustrations, accompanying text, parts lists
and exploded view drawings.
Pre-Delivery Check List
(DEALER RESPONSIBILITY)

customer and all operators read it before operating equipment. Point out the manual safety rules,
explain their meanings and emphasize the increased safety hazards that exist when safety
rules are not followed.
___Show customer how to make sure driveline is
properly installed and that spring-activated locking
pin or collar slides freely and is seated in groove
on tractor PTO shaft.
___Explain to customer the potential crushing haz-
ards of going underneath raised equipment.
Instruct that before going underneath to disconnect the driveline, securely block up all corners
with jack stands and to follow all instructions in
the “Service, blocking methods” section of the
operators manual. Explain that blocking up prevents equipment dropping from hydraulic leak
down, hydraulic system failures or mechanical
component failures.
___Show customer thesafe, proper procedures tobe
used when mounting, dismounting, and storing
equipment.
___For mounted units, add wheel weights, ballast in
front tires, and/or front tractor weight to enhance
front end stability. A minimum 20% of tractor and
equipment gross weight must be on front tractor
wheels. When adding weight to attain 20% of
tractor and equipment weight on front tractor
wheels, you must not exceed the ROPS weight
certification. Weigh the tractor and equipment.Do
not estimate!
___Make customer aware of optional equipment
available so that customer can make proper
choices as required.
