CHAPTER 1: INTRODUCTION
33” Wide Area Mower
Description of the Mower
The Troy-Bilt 33” wide cut mower was discontinued in
2005. It has since been completely redesigned and
released as a Cub Cadet for the 2007 season.
See Figure 1.1.
Figure 1.1
Some changes and features included on this mower:
• Easier access to the belts.
• Improved blade timing.
• Control rods replaced with cables.
• Controls are more user friendly.
• The mower is 20 lbs lighter.
• Deck Height Control.
• 2 gallon fuel tank.
Disclaimer: The information contained in this Manual is
correct at the time of writing. Both the product and the
information about the product are subject to change
without notice.
Disclaimer: This handbook is intended for use by
trained, professional technicians.
• Common sense in operation and safety is
assumed.
• In no event shall MTD or Cub Cadet be liable for
for poor text interpretation, or poor execution of
the procedures described in the text.
• If the person using this handbook is uncomfortable with any procedures they encounter, they
should seek the help of a qualified technician.
Fasteners
• Most of the fasteners used on the mower are
sized in fractional inches. Some are metric. For
this reason, wrench sizes are frequently identified in the text, and measurem ents are given in
U.S. and metric scales.
• If a fastener has a locking featu re th at has wo rn,
replace the fastener or apply a small amount of
releasable threadlocking compound such as
Loctite® 242 (blue).
• Some fasteners like cotter pins are single-use
items that are not to be reused.
Other fasteners such as lock washers, retaining
rings, and internal cotter pins (hairpin clips) may
be reused if the do not show signs of wear or
damage. This manual leaves that decision to
the judgement of the technician.
• 10.5 horse power Briggs engine. (Horse power
as rated by Briggs and Stratton)
• 33” cutting width.
• 4 speed Peerless Transmission.
• Simplified gear selector.
• Single lever deck height adjustments.
• Timed dual blades.
• Front (grease able) caster wheels for better
maneuverability.

Chapter 1: Introduction
Assembly
Torque specifications may be noted in the part of the
text that covers assembly, they may also be summarized in tables along with special instructions regarding
locking or lubrication. Whichever method is more
appropriate will be used. In many cases, both will be
used so that the manual is handy as a quick-reference
guide as well as a step-by-step procedure guide that
does not require the user to hunt for information.
The level of assembly instructions provided will be
determined by the complexity and of reassembly, and
by the potential for unsafe conditions to arise from mistakes made in assembl y.
Some instructions may refer t o other parts of the manual for subsidiary procedures. This avoids repeating
the same procedure two or three times in the manual.
Model and Serial Numbers
The model and serial number tag can is located in the
back of the mower. See Figure 1.2.

CHAPTER 2: MAINTENANCE
MAINTENANCE
Cleaning
Maintaining any piece of equipment begins with keeping it clean. Any spills such as fuel or oil should be
wiped off promptly. Use a mild detergent and water to
wash the mower.
NOTE: Do NOT use a pressure washer to clean
the mower. It may cause damage to the electrical components or remove lubrication that is
needed in critical areas.
NOTE: Using polishers like pledge on the plastic
components will affect their finish.
Use the Deck Wash System™ to rinse grass clippings
from the underside of the deck and prevent the build up
of corrosive chemicals caused by decaying vegetation
or fertilizers. It should only be done after the deck has
cooled down. Run the cutting deck for 15 minutes af terwards to dry the deck. After the deck is dry, inject one
squirt of grease in each spindle.
Lubricants
The grease used on this mower should be a high quality lithium based grease.
A high quality light weight oil such as WD 40 or 3-in-1
oil should be applied to all hinge and rotating points
that are not equipped with grease fittings.
Axle shafts
The rear axle shaft coming from the transmission is a
double-D shaft. As required of all double-D axle shafts,
the wheels should be removed once a year and the
shafts coated with anti-seize. See Figure 2.1.
Double-D
Figure 2.1
NOTE: Failure to remove the wheels once a
year and lubricating the axle shaft will usually
result in the rim rust welding to the axle shaft.
A drop of oil on the steel braid of the cables, where the
enter the cable jacket, will prolong the life of the cables.

MAINTENANCE
Front casters
The front caster wheels of the mower are equipped
with two grease fittings. Any grease injected into one
side of the wheel will migrate to the other side. A high
quality lithium grease is recommended. See Figure 2.2.
Grease
Grease fitting
Figure 2.2
The front wheel spindles are equipped with grease fittings and should be greased after each season of use
or every 50 hours what ever comes first.
See Figure 2.3.
fitting
Spindles
Both blade spindles are equipped with grease fittings.
The spindles should be greased every 50 hours or at
the end of the mowing season which ever comes first.
See Figure 2.4.
Grease fittings
Figure 2.4
CAUTION: Never put more that one squirt of
grease, per servicing, into a spindle. Putting
more that one squirt of grease into a spindle will
result in the bearings being pressed out of the
spindle housing.
Grease Fitting
Figure 2.3
NOTE: Failure to grease the front wheel spin-
dles could result in poor turning ability.
NOTE: Blades should be checked on a regular
basis for damage or dulling that has occurred
from regular use.
NOTE: Cutting with a dull or bent blade will
greatly reduce the quality of the cut.
NOTE: Replace any blade that is bent, damaged
or worn beyond the normal sharpening range.
CAUTION: If a blade is bent Do NOT try to bend
it back.

MAINTENANCE
Fasteners
Check all fasteners annually for any signs of lo osening
or damage.
Excessive vIbration is a primary cause of fatigue failures. Vibration can loosen fasteners and fatigue met al.
Transmission
The 4 speed peerless transmission has 16 oz.(454 ml)
of 80w-90 gear lube.
The gear lube should not need to be changed unless it
has become contaminated.
Engine
For maintenance and repair procedures, cont act the
engine manufacturer.
Emissions
In order to meet the new EPA regulations, there has
been some changes to the fuel system. The fuel tank
is blow moulded and composed of a high density polymer. The fuel cap has a ratchet feature that will prevent
the end user from over tightening it.
The fuel cap is vented through a small hole located in
the top of the inner fuel cap. The air is drawn in thro ugh
the gap between the inner and outer fuel cap shells.
See Figure 2.5.
Vent
Figure 2.5
Fuel line
IMPORTANT: This mower uses the Green-bar
low permeation fuel line that is mandated by the
EP A. It min imizes the gasolin e fumes th at percolate into the atmosphere through the fuel line.
Use the same type of line when replacing the
fuel line. See Figure 2.6.
Fuel line

CHAPTER 3: DRIVE SYSTEM
Drive system
A single belt is used to transfer power from the engine
crankshaft to the input shaft of the transaxle. The left
side control handle and cable operate a tensioner pulley that tightens the belt to engage the drive system
and loosens the belt to de-clutch the drive system.
Gear selection is done by a simple extension arm that
connects to the shift shaft of the transfer case.
Transaxle
The Transaxle is a peerless HMST-204-754, with 4 forward speeds, Neutral and 1 reverse.
The transaxle contains 16 fl oz (454 mL) of 80w90 gear
lube. It should not need to be changed, unless it
becomes contaminated or is drained to disassemble
the transaxle.
Complete service instructions can be found in the
Tecumseh/Peerless Motion Drive Systems handbook,
form #691218.
Drive Belt
To remove/replace the drive belt:
1. Remove the deck as described in the section on
the Drive Engagement Cable.
3. Remove the belt guide that is near the idler pulley using a pair of 7/16” wrenches.
See Figure 3.2.
Belt guide
Figure 3.2
4. Loosen the drive belt tension pulley two 9/16”
wrenches. See Figure 3.3.
2. Remove the belt guide that is near t he transm ission pulley using two 7/16” wrenches.
See Figure 3.1.
