GENERAL INFORMATION
may be general in nature, due to unknown and varying
operating conditions. However, through experience
and these instructions, you should be able to develop
procedures suitable to your particular situation.
■
Some illustrations in this manual show the
mower with safety shields removed to provide a
better view. The mower should never be operated
with any safety shielding removed.
The illustrations and data used in this manual were cur-
rent at the time of printing. However, due to possible
inline production changes, your machine may vary
slightly in detail. We reserve the right to redesign and
change the machines as may be necessary without
notification.
The purpose of this manual is to assist you in operating
and maintaining your mower. Read it carefully. It fur-
nishes information and instructions that will help you
achieve years of dependable performance. These
instructions have been compiled from extensive field
experience and engineering data. Some information
Throughout this manual, references are made to right

equipment as shown in the pamphlet that accom-
panies the driveline. Replace if damaged or broken.
Check that driveline guards rotate freely on drive-
line before putting equipment into 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.
Before starting the power unit, check all equip-
ment driveline guards for damage. Replace any
damaged guards. Make sure all guards rotate freely
on all drivelines. If guards do not rotate freely on
drivelines, repair and replace bearings before put-
ting equipment into service.
In addition to the design and configuration of
equipment, hazard control and accident preven-
tion are dependent upon the awareness, concern,
judgement, and proper training of personnel
involved in the operation, transport, maintenance
and storage of equipment.
Power unit must be equipped with ROPS or

from being run over or crushed. Keep foldable
ROPS system in “locked up” position at all times.
TRAINING
Remove accumulated debris from this equip-
ment, power unit, and engine to avoid fire hazard.
Safety instructions are important! Read all
attachment and power unit manuals; follow all
safety rules and safety decal information. (Replace-
ment manuals and safety decals are available from
your dealer.) Failure to follow instructions or safety
rules can result in serious injury or death.
Make sure all safety decals are installed.
Replace if damaged. (See Safety Decals section for
location.)
Make sure shields and guards are properly
installed and in good condition. Replace if damaged.

attachment quickly in an emergency.
If you do not understand any part of this manual
and need assistance, see your dealer.
Operators must be instructed in and be capable
of the safe operation of the equipment, its attach-
ments, and all controls. Do not allow anyone to
operate this equipment without proper instructions.
OPERATION
Never allow children or untrained persons to
operate equipment.
Full chain shielding must be installed when
operating in populated areas or other areas where
thrown objects could injure people or damage
property.
PREPARATION
Check that all hardware is properly installed.
Always tighten to torque chart specifications
unless instructed otherwise in this manual.
• If this machine is not equipped with full chain
shielding, operation must be stopped when any-
one comes within 300 feet (92 m).
• This shielding is designed to reduce the risk
of thrown objects. The mower deck and protec-
tive devices cannot prevent all objects from
escaping the blade enclosure in every mowing
condition. It is possible for objects to ricochet
and escape, traveling as much as 300 feet (92 m).
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
Make sure attachment is properly secured,
adjusted, and in good operating condition.
Inspect and clear area of stones, branches, or
other hard objects that might be thrown, causing
injury or damage.
Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.

under the influence of alcohol or drugs.
MAINTENANCE
Operate only in daylight or good artificial light.
Before working underneath, carefully read Oper-
ator’s Manual instructions, disconnect driveline,
raise mower, securely block up all corners with
jackstands, and check stability. Secure blocking
prevents equipment from dropping due to hydrau-
lic leak down, hydraulic system failures, or
mechanical component failures.
Keep hands, feet, hair, and clothing away from
equipment while engine is running. Stay clear of all
moving parts.
Always comply with all state and local lighting
and marking requirements.
Never allow riders on power unit or attachment.
Do not modify or alter or permit anyone else to
modify or alter the equipment or any of its compo-
nents in any way.
Always sit in power unit seat when operating
controls or starting engine. Securely fasten seat
belt, place transmission in neutral, engage brake,
and ensure all other controls are disengaged
before starting power unit engine.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
Operate tractor PTO at 540 RPM. Do not exceed.
Look down and to the rear and make sure area
is clear before operating in reverse.
Make sure attachment is properly secured,
adjusted, and in good operating condition.
Do not operate or transport on steep slopes.
Do not stop, start, or change directions sud-
denly on slopes.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Use extreme care and reduce ground speed on
slopes and rough terrain.
Make certain all movement of equipment com-
ponents has stopped before approaching for ser-
vice.
Watch for hidden hazards on the terrain during
operation.
Stop power unit and implement immediately
upon striking an obstruction. Dismount power unit,
using proper procedure. Inspect and repair any
damage before resuming operation.
Never go underneath equipment (lowered to the
ground or raised) unless it is properly blocked and
secured. Never place any part of the body under-
neath equipment or between moveable parts even
when the engine has been turned off. Hydraulic
system leak down, hydraulic system failures,
mechanical failures, or movement of control levers
can cause equipment to drop or rotate unexpect-
edly and cause severe injury or death. Follow Oper-
ator's Manual instructions for working underneath
and blocking requirements or have work done by a
qualified dealer.
TRANSPORTATION
Use additional caution and reduce speed when
under adverse surface conditions, turning, or on
inclines.
Do not operate PTO during transport.
A minimum 25% of tractor and equipment
weight must be on the tractor front wheels when
attachments are in transport position. Without this
weight, tractor could tip over, causing personal
injury or death. The weight may be attained with a

CUTTING HEIGHT ADJUSTMENT
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
NOTICE
■
Avoid low cutting heights. Striking the ground
with blades produces one of the most damaging
shock loads a mower can encounter. Allowing
blades to contact ground repeatedly will cause
damage to mower and drive.
1. Level mower from side to side. Check by
measuring from mower frame to the ground at
each deck rail.
2. Verify that the same amount of spacers are under
all caster arms.
3. Loosen cap screws that attach caster arm
assembly to deck.
4. Set mower on the ground.
5. Retighten cap screws. This equalizes the
clearance in the bolt holes.

FRONT CASTER WHEEL INTERFERENCE
CHECK
Power for operating mower is supplied by tractor PTO.
Operate PTO at 540 rpm. Know how to stop tractor and
mower quickly in an emergency.
NOTICE
■
Do not operate tractor and mower until this
interference check has been performed. If you
change tractors, you must perform the check for
that mounting.
If mower becomes plugged causing belt to slip for over
two seconds follow these steps:
1. Maneuver equipment into a previously cut area
and allow mower to clear accumulated material.
2. Continue running at least two minutes, allowing
pulleys to cool. Stopping the mower in contact with
a very hot pulley will bake and ruin belt.
Proper ground speed will depend upon the terrain, the
height, and type and density of material to be cut.
Normally, ground speed will range from 2 to 5 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 to maintain
proper blade speed and produce a clean cut.
Figure 8. Front Caster Wheel Interference Check
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 par-
tially rebound.
Perform this check with all of the spacers above caster
wheel arm. This will place caster wheels in their highest
position and provide lowest cutting height for mower.
1. Raise mower with tractor hydraulics to 16" at
dimension C or maximum height of tractor lift,
whichever is less.
In general, lower cutting heights give a more even cut
and leave less 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 recom-
mendations for the suitable cutting height in your area.
2. Pivot both front caster wheels forward and check
that there is clearance between caster wheels and
tractor tires.
3. If there is interference adjust mower hitch arm (E)
as shown in Figure 7.
NOTE: If interference continues, see tractor operator's
manual and adjust tractor wheels to narrower spacing.
Operating Tips
FRONT ROLLER (OPTIONAL)
Inspect and clear area of stones, branches, or
other hard objects that might be thrown, causing
injury or damage.
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 the mower to con-
tact ground and scalp. An optional front roller may be
installed to minimize scalping. See page 31.
Extremely tall material should be cut twice. Set mower
at a higher cutting height for the first pass. Then cut at
desired height, 90 degrees to the first pass.
OPERATING TECHNIQUE
Remember, sharp blades produce cleaner cuts and
require less power.
CAUTION
Analyze area to be cut to determine the best proce-
dure. Consider height and type of grass and terrain
type: hilly, level, or rough.
Stop power unit and implement immediately
upon striking an obstruction. Dismount power unit,

denly on slopes.
___ Check to ensure blades are sharp, in good condi-
tion, and installed correctly. Replace if damaged.
Use extreme care and reduce ground speed on
slopes and rough terrain.
___ Check that equipment is properly and securely
attached to tractor.
Watch for hidden hazards on the terrain during
operation.
___ Make sure driveline spring-activated locking pin
or collar slides freely and is seated firmly in trac-
tor PTO spline groove.
Pass diagonally through sharp dips and avoid sharp
drops to prevent hanging up tractor and mower.
___ Make sure the driveline guards and tether chains
are in good condition. Guards must rotate freely
on driveline. Fasten tether chains to the tractor
and the equipment as instructed.
Practice will improve your skills in maneuvering rough
terrain.
MOWER REMOVAL & STORAGE
___ Inspect area and remove stones, branches or
other hard objects that might be thrown, causing
injury or damage.

OWNER SERVICE
The information in this section is written for operators
who possess basic mechanical skills. If you need help,
your dealer has trained service technicians available.
For your protection, read and follow the safety informa-
tion in this manual.
Never allow children or untrained persons to
operate equipment.
Keep bystanders away from equipment.
Before working underneath, carefully read Oper-
ator’s Manual instructions, disconnect driveline,
raise mower, securely block up all corners with
jackstands, and check stability. Secure blocking
prevents equipment from dropping due to hydrau-
lic leak down, hydraulic system failures, or
mechanical component failures.
Figure 9. Blocking Method
LUBRICATION INFORMATION
Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Figure 10 shows the lubrication points. The accompa-
nying chart gives the frequency of lubrication in operat-
ing hours, based on normal operating conditions.
Operate tractor PTO at 540 RPM. Do not exceed.
Severe or unusual conditions may require more fre-
quent lubrication. Some reference numbers have more
than one location; be sure you lubricate all locations.
CAUTION
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
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 the lubrication
chart, one good pump of most guns is sufficient.
Use SAE 90W gear lube in the gearbox. Fill to plug on
side of gearbox.
BLOCKING METHOD
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.
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.
Raise mower completely, set tractor brakes, turn
engine off, remove key, block tractor wheels front and
rear, and disconnect mower driveline from tractor.
Overfilling the gearbox will cause the excess gear lube
to blow out vent plug and ruin the belt.
The only approved blocking device for this mower is a
jackstand with a load rating of 1000 pounds or more.
One jackstand under each corner of the mower (four
total) must be installed before working underneath.
Driveshaft Lubrication
Lubricate the driveshaft slip joint every 8 operating
hours. Failure to maintain proper lubrication could
result in damage to U-joints, gearbox, and driveshaft.
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 por-
tion of the mower.
1. Lower mower to ground.
2. Apply grease at five locations shown in Figure 10.
3. Raise and lower mower several times to distribute
grease.

NOTICE
■ Use care when installing or removing belt from
spring-loaded idler at step 6. Springs store energy
when extended and, if released suddenly, can
cause personal injury.

Before dismounting power unit or performing
any service or maintenance, follow these steps:
disengage power to equipment, lower the 3-point
hitch and all raised components to the ground,
operate valve levers to release any hydraulic pres-
sure, set parking brake, stop engine, remove key,
and unfasten seat belt.
BELT SERVICE
Belt Replacement
One of the major causes of belt failure is improper
installation. Before installing a new belt, check the fol-
lowing:
1. Check pulley shafts and bearings for wear.
2. Check pulley grooves for cleanliness.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
3. 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.
Blade Removal
1. Remove Nylok bolt (5).
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.
2. Remove blade lock (4) from groove in blade pin.
3. Remove blade (2) and pin (3) from spindle
assembly (1).
Belt Installation
1. Disconnect idler spring from deck lug I.
2. Slide belt under drive pulley A and over idler arm.
Position belt around drive pulley A.
3. Route belt around pulley B, idler C and pulley D as
shown.
4. Make sure belt is on drive pulley A, route around
idler E, and connect idler spring to lug I on deck.

CAUTION
2. Do not sharpen blade to a razor edge. Leave at
least a 1/16" blunt edge.
Your dealer can supply genuine replacement
blades. Substitute blades may not meet original
equipment specifications and may be dangerous.
3. Do not sharpen back side of blade.
CHAIN SHIELDING
Full chain shielding must be installed when
operating in populated areas or other areas where
thrown objects could injure people or damage
property.
• If this machine is not equipped with full chain
shielding, operation must be stopped when any-
one comes within 300 feet (92 m).
• This shielding is designed to reduce the risk
of thrown objects. The mower deck and protec-
tive devices cannot prevent all objects from
escaping the blade enclosure in every mowing
condition. It is possible for objects to ricochet
and escape, traveling as much as 300 feet (92 m).

GEARBOX REPAIR
Read this entire section before starting any repair.
Many steps are dependent on each other.
Seal Replacement
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 to anything other
than replacement of bearings, seals or gaskets is
required.
Recommended sealant for gearbox repair is Perma-
tex® 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.
Fill gearbox with SAE 80W or 90W gear lube until it
runs out the side level plug.
Seal Installation
Inspect gearbox for leakage and bad bearings.
Leakage is a very serious problem and must be cor-
rected immediately.
NOTE: Proper seal installation is important. An improp-
erly installed seal will leak.

ASSEMBLY INSTRUCTIONS
DEALER SET-UP INSTRUCTIONS
Assembly of this mower is the responsibility of the
Frontier dealer. If should be delivered to the owner
completely assembled, lubricated, and adjusted for
normal cutting conditions.
Before working underneath, carefully read Oper-
ator’s Manual instructions, disconnect driveline,
raise mower, securely block up all corners with
jackstands, and check stability. Secure blocking
prevents equipment from dropping due to hydrau-
lic leak down, hydraulic system failures, or
mechanical component failures.
Complete Dealer Check Lists on page 33 when you
have completed the assembly.
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 43.
CAUTION
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
Select a suitable working area. Open parts boxes and
lay out parts and hardware to make location easy.

BOLT TORQUE CHART
Always tighten hardware to these values unless a different torque value or tightening procedure is listed for a specific
application.
Fasteners must always be replaced with the same grade as specified in the manual parts list.
Always use the proper tool for tightening hardware: SAE for SAE hardware and Metric for metric hardware.
Make sure fastener threads are clean and you start thread engagement properly.
All torque values are given to specifications used on hardware defined by SAE J1701 MAR 99 & J1701M JUL 96.
