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/or side skids drop
into depressions and allow center of mower to contact
ground and scalp. An optional front roller may be
installed to minimize scalping.
Inspect area to be cut and remove stones,
branches or other hard objects that might be
thrown, causing injury or damage.
IMPORTANT
J Mower vibration tends to loosen bolts
during operation. All hardware should be
checked regularly to maintain proper
torque. It is a good practice to check
mower before each operation to ensure all
hardware is secure.
Operating Techniqu e
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.
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 with a very hot pulley will bakeand ruin belt.
CAUTION
J Stop tractor and implement immediately upon striking an obstruction. Turn
off engine, remove key, inspect and repair
any damage before resuming operation.
Pre-Operation Check List
(OWNER RESPONSIBILITY)
Review and follow safety rules on pages 4
through 7.
Check that mower is properly and securely
attached to tractor.
Make sure driveline spring-activated locking pin
slides freely and is seated firmly in tractor PTO
spline groove.
Operate tractor PTO at 540 rpm.
Lubricate all grease fitting locations. Make sure
PTO shaft slip joint is lubricated.
Check to be sure gearbox is half-full of SAE 90W
gear lube.
Check that all hardware is properly installed and
secured.
Check to ensure blades are sharp and secure
and cutting edge is positioned to lead in a
clockwise rotation.
Proper ground speed will depend upon the terrain, the
height, type and density of material to be cut.
Normally, ground speed will range from two to five
mph. Tall dense material should be cut at a low 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 and
invites weed growth during growing seasons. Follow
local recommendations for the suitable cutting height
in your area.

Tips
WARNING
J Inspect and clear area of stones,
branches or other hard objects that might
be thrown, causing injury or damage.
Extremely tall material should be cut twice. Set
mower 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.
J Do not stop, startor changedirections
suddenly on slopes.
J Use extreme care and reduce ground
speed on slopes and rough terrain.
J Watch for hidden hazards on the terrain during operation.
Pass diagonally through sharp dips and avoid sharp
drops to prevent “hanging up” tractor and mower.
Analyze area to be cut to determine the best
procedure. Consider height and type of grass and
terrain type: hilly , level or rough.
Plan your mowing pattern to travel straight forward
whenever possible. Mow with uncut grass to the left.
This will distribute the clippings over the cut area.
Discharging clippings over uncut grass will cause a
buildup and may prevent uniform cutting.
Uneven Terrain
WARNING
J Do not operate on steep slopes.
Practice will improve your skills in maneuvering rough
terrain.
Removing Mower from Tractor (Figure 6)
Disengage tractor PTO, raise mower with 3-point
hitch and remove check chains (if installed) from
brackets attached to tractor top link brackets.
Disconnect mower driveshaft from tractor PTO.
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.

CAUTION
J 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.
BLOCKING METHODS
Jackstands, with a load rating of 1,000 pounds or
more, are the only approved blocking device for this
mower. A minimum of four jackstands, located under
the mower as shown in Figure 7A, must be installed
before working underneath this unit. Do not position
jackstands under wheels, axles, or wheel supports
because these components can rotate.
Do not work underneath unless it is properly attached
to tractor (see Operation section), the brakes set, key
removed, and the mower blocked securely. The
mounted unit will be anchored to minimize side to side
and front to rear movement.
For the mounted unit, tighten tractor lower 3-point
arm anti-sway mechanisms to prevent side to side
movement.
LUBRICATION INFORMATION (Figure 7)
Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
Figure 7 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.
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 applied according to thelubrication
chart, one good pump of most guns is sufficient.
Use SAE 90W gear lube in the gearbox. Check
gearbox using dipstick. Oil level is to be up to the ring
but not over. See Figure 7.
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 lube emitted from the vent plug; this
is not considered leakage.
When blocking, you must consider overall stability of
the unit. Just placing jackstands under the unit willnot
ensure your safety.The working surface must be level
Overfilling the gearbox will cause the excess gear
lube to blow out vent plug. The gear lube could then
ruin the belt.

BELT REPLACEMENT (Figure 8)
BLADE SERVICING
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 and without 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 to pry belt into pulley groove. Do not roll belt over
pulleys to install. This can cause hidden damage and
premature belt failure.
IMPORTANT
J Use care when installing or removing
belt from spring-loaded idler at step 5.
Springsstore energy when extended and,
if released suddenly, can cause personal
injury.

Remove seals from housing.
Remove bearing cups from housing as described in
Bearing cups and cones are designed to work
together. It is important to position them so bearing
cone taper mates with bearing cup taper.
Lubricate new cups (6) with a light oil. Place them in
spindle housing (5) so they will mate with cones (4).
Seat cups (6) against machined shoulder of housing
with a press or by placing a large drift on the flat lip
and driving them into housing.
Place bottom bearing cone (4) onto spindle shaft (7)
with taper up. Seat on bottom shoulder of shaft with a
press.
Insert shaft and bearing cone assembly through
bottom of housing (5). Fill housing cavity with a lithium
grease of #2 consistency with a MOLY (molybdenum
disulfide) additive. Place top bearing cone (4) on shaft
(7) to mate with top bearing cup.
IMPORTANT
J Bearing adjustment is set by pressing
sleeve against bearing cone until proper
adjustment is attained.
Install sleeve (3) on shaft and press sleeve and
bearing cone onto shaft until all bearing free play is
removed andthere is a slight drag (similar to adjusting
the front wheel bearings on an automobile). Check by
spinning spindle. It should turn freely.
Be careful not to overtighten bearings. Proper bearing
adjustment is essential to good bearing life.

Should you overtighten bearings, hold spindle housing and rap spindle shaft with a lead hammer to
loosen bearings. Readjust bearings until proper
setting is obtained.
IMPORTANT
J Improper positioning of seals can
cause seal failure.
Proper seal installation is important. An improperly
installed seal will leak and could cause bearing failure.
Pull the rubber portion of seal back and locate spring.
Apply a thin coat of lubricant to bottom seal (2) and
install with spring up toward center of housing.
Place bottom seal squarely on housing. Select a piece
of pipe or tubing with an OD that will set on outside
edge of seal. A tube that is too small will bow seal cage.
Carefully press seal into housing, preventing distortion to metal seal cage. Seal should seat firmly and
squarely against machined shoulder in housing.
Make sure seal lip did not roll under. Distortion to seal
cage or damage to seal lip will cause seal to leak.
Damaged seals must be replaced.
Apply a thin coat of lubricant to top seal (2) and install
with spring up away from center of housing. Top seal
should be flush with top of housing.
Lubricate spindle with a lithium grease of #2 consistency with a MOLY (molybdenum disulfide) additive.
Vent top seal with blunt edged tool, such as a letter
opener, while filling with grease. Rotate housing on
spindle shaft, checking for free movement.
Blade Spindle Installation
Insert spindle through bottom of mower deck and
secure with cap screws and lockwashers previously
removed. Be sure to position grease fittings toward
lubrication access areas. Reinstall grease fitting
extension after spindle is secured in place. Refer to
lubrication chart, page 15.

IMPORTANT
J Pulley installation sequence is very
important for bearing life. Follow the
sequence exactly.
Install pulley and split taper bushing with integral key
on spindle shaft. Install cap screw and flat washer in
top of spindle shaft. Torque this cap screw to 12
lbs.-ft.,thenalternately tightensplittaper bushing cap
screws to 12 lbs.-ft.
GEARBOX MAINTENANCE
Read all of this section before starting any repair.
Many steps are dependent on each other.
Check gearbox for leakage and shaft side and end
play.If excessive shaft play is found, disassemble box
and inspect bearings and shafts.
Leakage can occur at top cover and at shaft seals.
Leakage problems should be corrected immediately
to prevent damage to drive belt from gearbox oil.
Always clean any spilled lubricant with a cloth
moistened with a non-flammable, non-toxic degreasing agent or commercial detergent and water. Be sure
to clean pulley grooves.
The sealants recommended for gearbox repair are

Remove drive belt from drive sheave.
Remove gear stand from mower.
Remove drive sheave from mower by removing cap
screws from split taper bushing and turning them into
threaded holes on bushing flange. Tighten evenly,
forcing the bushing and drive sheave apart.
Remove gearbox from gear stand.
Gearbox Disassembly (Figure 12)
A five ton press will be required for vertical gear shaft
removal.
WOODS puller kit (PN--19077) is required to remove
the horizontal shaft from the gearbox.
Remove top cover (14) and drain all gear lube.
Clamp gearbox upside-down in a large vise. Place
driveline on the horizontal shaft to prevent shaft
rotation. Remove stake nut (23). If nut is too tight to
remove with a spanner wrench, loosen with punch
and hammer.
Carefully remove vertical shaft seal (21) to prevent
damage to shaft threads and seal bore.
Remove PTO driveline and remove gearbox from
vise. Use care when removing horizontal shaft seal
(1) and retaining ring (2) to prevent damage to shaft
seal surface and housing bore.
Leakage Repair
To repair top cover leakage, clean top cover and
housing sides, then remove cover. Remove old
sealant from cover and housing.
Apply sealant to top cover and replace. Reinstall cap
screws in top cover and torque to 38 lbs.-ft.
Horizontal seal leakage should be repaired by
replacing the seal. The gearbox should be removed
from the mower to accomplish this. Remove old seal
with care to prevent damage to seal bore and shaft.
Sealant should be applied to the seal bore before
installing the new seal. The new seal should be
seated squarely in the bore against snap ring. Press
seal into place with a piece of pipe or tubing that sets
against the outside edge of the seal. Tubing with an
outside diameter which is too small will bow seal cage
and ruin the seal.
Removing Gearbox from Mower
Remove belt and driveline shields.
Remove rear driveline shield retainers and pull shield
ahead to gain access to front of gearbox. Remove
snap ring from gearbox shaft. Remove shear bolt
from end yoke and remove driveline.

Secure input gear (8) against housing with a “C”
clamp. Place puller plate (30) over horizontal shaft
(6). Assemble puller halves together as shown in
Figure 12 using bolt (28 and nut (29). Puller flanges
must engage locking groove in horizontal shaft.
Tighten puller bolts evenly to remove shaft from
housing.
Place housing upside-down in a press and remove
vertical shaft (15) by pressing through top of housing.
Remove bearing cone (16) from vertical shaft (15)
with a spreader. Remove all cups from housing with a
puller or by carefully driving them out with a punch.
Inspect gears for excessive wear. Gears are forged
and surfaces will appear rough, even when new.
Some wear is normal. Gears will show more wear on
the loaded side and the pattern should be smooth.
Inspect both gear shafts and stake nut for grooves,
nicks, or bumps where the seals seat. Replace if
damage cannot be repaired by resurfacing with
emery cloth.
Clean gearbox housing and inspect for damage.
Replace if cracks are found.
