INTRODUCTION
We are pleased to have you as a Bush Hog customer. Your Bush Hog Zero Turn Riding Mower
has been carefully designed with care and built with quality materials by skilled workers to give
maximum service with minimum down time. This manual is provided to give you the necessary
operating and maintenance instructions for keeping your Zero Turn Mower in top operating condition. Careful use and timely service saves extensive repairs and costly down time losses.
Please read this manual thoroughly. Understand what each control is for and how to use it. No
shielding is 100% effective in preventing thrown objects. The possibility of injury and property
damage from this hazard can be substantially reduced by selecting proper shielding, maintaining
the Zero Turn Mower and shielding in good operational condition, inspecting the area for foreign
debris before mowing, and operating the Zero Turn Mower at a minimum cutting height, Keep
unprotected persons at a minimum distance of 300 feet from the Zero Turn Mower at all times
during operation. Safety is of primary importance to the owner/operator and to the manufacturer.
Observe all safety precaution decals on the Zero Turn Mower and noted throughout the manual
for safe operation of Zero Turn Mowers. If any assistance or additional information is needed,
contact your authorized Bush Hog dealer. The owner/operator/dealer should know and understand the Safety Messages before assembly and be aware of the hazards of operating this Zero
Turn Mower during assembly, use, and maintenance. The Safety Alert Symbol combined with
a Signal Word, as seen below, is intended to warn the owner/operator of impending hazards
and the degree of possible injury faced when operating this Zero Turn Mower.
INTRODUCTION
INTRODUCTION
The Bush Hog Zero Turn is intended for use on lawns and other frequently
maintained areas where a smooth, even cut is desired and superior maneuverability is needed. The Power Unit consists of a Briggs & Stratton,
Kawasaki, or Kohler twin cylinder engine. The engine has a pressurized oil
lubrication system with spin-on type filter, fused electronic ignition, electric
start and the Zero Turn has a 8 gallon fuel system.
Two hydrostatic transaxles are used for propelling and steering. The
Transaxles are belt driven by the engine output shaft. One lever for each
drive controls both speed and direction. This independent control of each
drive wheel coupled with continuously variable speed selection gives the Zero Turn mower exceptional maneuverability.
The Zero Turn Mower Deck is available in 49”, 55” or 61” cutting widths. The Zero Turn Mower
has three cutting blades, driven by an electromagnetic clutch through a single v-belt.
Front, rear, left and right are determined by the normal direction of travel, the same as driving an
automobile.

Mowing Tips
Before mowing check the area to
be mowed for debris that can be
removed. Objects that are fixed
and cannot be removed, flag the object so a collision
does not occur.
! CAUTION
●Start by setting the Zero Turn Mower at the desired cutting height so desired result is attained. The average
lawn should be cut to a height of 2-1/2’’
during cool seasons and 3” during hot months. For healthier, better looking lawns mow often after moderate growth
has occurred.
●Grass over 6” in height should be mowed twice. Make

change the operating angle. Keep away from drop offs
and steep banks. Tall grass can hide these obstacles.
●Mowing results are best when the engine is a full throt-
●Use caution near drop offs, ditches, or embankments.
The Zero Turn Mower can suddenly turn over if a wheel
goes over an edge of a ditch, drop off, embankment, or
an edge caves in.
●Mow a safe distance from water’s edge (Ponds or
Lakes). A Danger Zone of 10 feet should be observed.
tle (blades spin faster) and the travel speed is low. If
grass is low, travel speed can increase without affecting
mowing results.
●Avoid mowing when grass is damp or wet. The mowing
results can be poor and cause the wet grass to clump
under the deck and stick to the underside of the mowing deck, resulting in an uneven cut.
After Mowing is Completed
●After the Zero Turn Mower is shut down and the engine
has cooled, use compressed air to clean the top surfaces of the Zero Turn Mower deck and frame. If compressed air is not available a leaf blower can be used.
●Avoid using water on top surfaces around engine and
electrical components.
●Raise the Zero Turn Mower deck to its highest position
and hose the underside of the Zero Turn Mower deck
to remove any build up of grass clippings.

The Zero Turn Mower must be parked on a level surface, parking brake set and bypass lever on each
transaxle applied.
MAINTENANCE
Purging Procedures
7. Drain old oil filters of all free flowing oil prior to disposal.
Place used oil in appropriate containers and deliver to an
approved recycling collection facility.
These purge procedures should be implemented any
time a hydrostatic system has been opened to facilitate maintenance or the oil has been changed.
8. Remove the Top Port Plug from the left side and right
side transaxles prior to filling with oil. This will allow the
transaxles to vent during oil fill.
Due to the effects air has on efficiency in hydrostatic
drive applications, it is critical that it is purged from the
system.
Air creates inefficiency because its compression and expansion rate is higher than that of the oil approved for
use in hydrostatic drive systems.
MAINTENANCE
6. Repeat steps 1-5 on the opposite side transaxle drive.
The resulting symptoms in hydrostatic systems may be:
1. Noisy operation.
2. Lack of power or drive after short term operation.
3. High operation temperature and excessive expansion
of oil.
Before starting, make sure the transaxle is at the
proper oil level. If it is not, fill to the specifications
outlined in this manual. Refer to steps 10-12 under
Fluid and Filter Change Procedure
Top Port Plug
9. Remove the cap from the transaxle’s Oil Reservoir
Tank located on the vehicle frame.
The following procedures are best performed with
the vehicle drive wheels off the ground. Then repeated under normal operating conditions.
If this is not possible, then the procedure should be
performed in an open area free of any objects or bystanders.
1. Disengage the brake if activated.
2. With the bypass valve open and the engine running,
slowly move the directional control in both forward and
reverse directions (5 or 6 times).
Oil Reservoir Tanks
10. Fill with 20W50 motor oil until oil just appears at the
bottom of each transaxle’s top port (approximately 2 qts.
per transaxle, 4 qts. total). Install the top port plug into
each transaxle as the oil level reaches this port.
Note: The oil volume figure shown does not include what
is in the Oil Reservoir Tank hose or the Oil Reservoir
Tank.
3. With the bypass valve closed and the engine running,
slowly move the directional control in both forward and
reverse directions (5 to 6 times). Check the oil level, and
add oil as required after stopping the engine.
4. It may be necessary to repeat Steps 2 and 3 until all
the air is completely purged from the system. When the
transaxle operates at normal noise levels and moves
smoothly forward and reverse at normal speeds, then the
transaxle is considered purged.
11. Install and torque the Top Port Plugs to 180 in. lbs.
(20.3 Nm).
12. Continue to fill the transaxles through the Oil Reservoir Tank until the “Full Cold” line is reached on the HydroGear Oil Reservoir Tank.
13. Re-install the Oil Reservoir Tank cap by hand. Be
careful to not overtighten.
14. Proceed to Purging Procedures.

General Care
Low Oil Alarm - If the oil pressure switch closes for ten
seconds while the engine is running, the console displays
“OIL” “PSI” on the LCD (11), flashes the low oil alarm
LED indicator, and shuts down the engine. The alarm is
reset when the engine is restarted, or when the console
goes to sleep.
The Console is a completely sealed instrument designed
to withstand exposure to outdoor environments. Pressure
washing of the console face is acceptable when water
spray pressure does not exceed 2000 psi while using a
30 degree or greater nozzle tip (fan spray) at a distance
no closer than 12”. Oil, gasoline, chemicals and detergents spilled on the console should be wiped off immediately with a clean dry cloth.
Never use abrasive or corrosive cleaning products on the
console.
The alarm may also be configured to lock out the PTO
but leave the engine running. In this configuration, the
alarm is immediately reset when the oil pressure switch
opens.
Bypassed or Failed Safety Interlock Switch
Detection
Low Voltage Alarm - While the console is unlocked by
entering your Key Code, and the system voltage is below
12.0 V for 90 seconds, the console displays “LOW
VOLTS” and the current system voltage. This alarm is
reset when the system voltage rises above 12.0 V or
when the console goes to sleep.
While monitoring the safety interlocks, the console identifies interlock switches that have failed, closed, or have
been bypassed closed. When the console detects a
failed or bypassed switch, it slowly flashes the corresponding indicator LED and flashes “SEAT”/”BRAKE”/”DRIVE”
“INTLK” “FAULT” on the LCD.
High Voltage Alarm - While the console is unlocked by
entering your key code, and the system voltage is above
15.0 V for more than 2 seconds the console displays

STORAGE
Winter Storage
New Season Preparation
At the end of the mowing season, or when it will not be in
use for more than 30 days, the Zero Turn Mower should
be readied for storage.
Fuel allowed to stand for long periods of time (30 days
or more) can leave sticky residues that can plug the carburetor and disrupt engine function.
Fuel stabilizers are an acceptable option as regards to
the sticky residues that can occur during storage.
Add stabilizer to the fuel in the tank and in the storage
container.
Always use the mixing ratios specified by the manufacturer of the stabilizer.
Run the engine for at least 10 minutes after adding the
stabilizer so that it reaches the carburetor. Do not empty
the fuel tank and the carburetor if you have added stabilizer.
Before starting the mower following post season storage,
the following service is required:
come in contact with open flames, sparks, or a pilot light
such as in a boiler, hot water tank, clothes dryer, etc.
Handle the fuel with care. Gasoline Fumes are very flammable and can cause serious personal injury and property damage. Drain the fuel into an approved container
outdoors and store far away from open flame or sources
of ignition. Never use gasoline for cleaning. Use a degreaser and warm water instead.
Preparing the Machine for storage:
1. Thoroughly clean the Zero Turn Mower, especially
under the Zero Turn Mower deck. Touch up damage to
the paint and spray a thin layer of oil on the underside of
the Zero Turn Mower deck to avoid corrosion.
2. Inspect the Zero Turn Mower for worn or damaged
parts and tighten any nuts or screws that may have become loose.
3. Change the engine oil; dispose of properly.
4. Empty the fuel tanks or add a fuel stabilizer. Start the
engine and allow it to run until the carburetor is drained
of fuel or the stabilizer has reached the carburetor.
5. Remove the spark plug and pour about a tablespoon
of engine oil into the cylinder. Turn over the engine so
that the oil is evenly distributed and then re-install the
spark plugs.
1. Clean Zero Turn Mower, removing trash and dirt accumulation.
2. Check engine oil and hydraulic oil levels.
3. Fill fuel tank with fresh fuel. Run Zero Turn Mower at
half speed for 5 minutes, checking operation of steering
control lever. Stop engine and check for oil leaks, loose
fittings.
4. Tighten any bolts that have loosened and make sure
all hair pins, cotter pins and clevis pins are in place.
5. Check that all safety shields are in place and secure
and review safety precautions listed in this manual.
6. Check Mower belt and drive belt for damage or severe
cracking and replace if needed.
7. Check Mower blades for sharpness and damage. Replace or sharpen if needed.
8. Check and inflate tires to 15 psi / 1 bar / 103 kPa.
9. Install fully charged battery and attach the battery cables.
10. Check Safety system startup. Refer to Safety System in the Maintenance Section.
11. Refer to engine manual for more information.
If Service Parts are required
after New Season Preparation
check is completed use only Genuine Bush Hog
Parts. The use of “Will Fit” parts may reduce Zero
Turn Mower performance, void warranty and present a safety hazard.
IMPORTANT!
6. Lubricate all grease fittings, joints, and axles.
7. Remove the battery. Clean, charge, and store the battery in a cool place, but protect it from direct cold or freezing.
8. Store the Zero Turn Mower in a clean, dry place and
cover it for extra protection.
