XL OWNER’S MANUAL

A Message from Mudd-Ox Inc.
Thank you for choosing the Mudd-Ox as your new amphibious ATV.
We began designing the first Mudd-Ox in 2005, spending years testing and developing the ultimate amphibious
vehicle. The first production machine rolled off the line in 2008 and was shipped to Australia. Since then, we have
expanded our model lineup to include the Mudd-Ox GT, XL, Fort Mac, and Vengeance to suit all your outdoor needs.
Our journey has continued to be full of adventure.
Safety is our number one concern. Be sure to read and understand this entire manual to ensure the safety of your-
self and others with the Mudd-Ox.
Mudd-Ox is proudly made in the USA. Our headquarters and manufacturing facility are located near the historic
town of Shipshewana, Indiana. We welcome everyone to come visit our facility and take in the local beauty that is
rural Indiana.

Identify Your Mudd-Ox
PIN Plate
Each Mudd-Ox has its own unique identification plate. It notates the Model and Product Identification Number
(PIN). This information is vital for identifying each individual Mudd-Ox and obtaining a state-issued title. Never
remove the PIN plate from the Mudd-Ox.
Locating the PIN
On the interior of the Mudd-Ox in front of the parking brake handle locates the PIN plate. It is visible without
removing any components, however removing the lower operator seat is recommended for best visibility.
Document Your Information
Write down the Model and PIN information just as it displays on the PIN plate to document your individual Mudd-Ox.

Warranty
Limited Warranty: Mudd-Ox Inc. (“Mudd-Ox”) hereby warrants to the original purchaser that any components of your
new Mudd-Ox vehicle manufactured by Mudd-Ox will be free from defects in material and workmanship for a period of
(1) year from date of purchase or 500 hours, whichever comes first, exempt as otherwise noted. Dealer demo vehicles are
warrantied for (30) days.
Mudd-Ox Warranty Responsibilities: Mudd-Ox, if notified of a defect in material or workmanship during the period of
warranty, will repair or replace, at its option, defective parts covered by this warranty at no charge other than the reason-
able cost for the transportation of components, if applicable. Mudd-Ox will also pay reasonable charges for necessary labor
to perform warranty repairs.
Warranty Claim Procedures: In order to be able to submit claims under this warranty, the original purchaser must main-
tain and operate the vehicle in accordance with instruction provided: in the Owner’s Manual; engine manufacturer’s manu-
al; in any manual related to components of the vehicle; and on labels affixed to the vehicle. To initiate a warranty claim pro-
cedure, the original purchaser must contact the Mudd-Ox Customer Service Department within (10) days of the discovery
of an alleged defect. Mudd-Ox’s Customer Service Department may be contacted using the following methods: by calling +1
260-768-7221, in person or by mail at Mudd-Ox Inc, 8525 W 750 N Shipshewana, IN 46565, or online at www.muddox.net.
The repair or replacement of any part(s) under this Limited Warranty shall not extend the term of the warranty beyond the
original term as set forth above. Products which Mudd-Ox Inc. determines violate such warranty shall be returned to the
BUYER at the BUYER’S expense. Any parts required for warranty that are not in the dealer’s inventory will be shipped to the
servicing dealer via UPS Ground or USPS priority mail at Mudd-Ox Inc. discretion.
General Exclusions: This limited warranty does not cover component failure or damage caused by any of the following:
abnormal strain or stress; neglect; abuse; theft; fire; improper assembly of components which were supplied in the factory
sealed carton after the vehicle left Mudd-Ox; improper maintenance or repair; modifications; damage caused by use of
non-Mudd-Ox accessories; or improper use of the vehicle including but not limited to: racing, jumping, stunt driving, or any
other uses prohibited in the Owner’s Manual. Additionally, this warranty does not cover vehicles which are leased, rented,
or used at a concession track. This warranty does not cover components not manufactured by Mudd-Ox. For warranty
information on components not manufactured by Mudd-Ox, please refer to each component’s respective manufacturer’s
warranty.
Specific Exclusions: This limited warranty does not apply to components which are subject to normal wear and tear. These
items are not limited to: axles; track keepers; wheels; tires; batteries; throttle; shift, steer and brake cables; drive belt; the
torque converter system; chain; seat; lights; fasteners; decals; or body panels and natural cosmetic discoloration of mate-
rial due to ultraviolet light. Shipping method of parts, incorrectly damaged components, downtime, and delivery charges
are not covered by this warranty. This warranty does not apply to the vehicle’s batteries. The batteries carry a separate
warranty provided by Mudd-Ox’s battery supplier. Please refer to the battery supplier’s warranty policy for their warranty
requirements and procedures.
No Implied Warranty of Fitness or Merchantability: There are no warranties that extend beyond the description on
the face hereof. Specifically, Mudd-Ox makes no other warranty of any kind, express or implied. All warranties of fitness
or merchantability for a particular purpose that exceed the obligations and time limitations specified in this warrant are
hereby disclaimed by Mudd-Ox and excluded from this warranty. Additionally, this warranty excludes any incidental or
consequential damages, including but not limited to loss of use. Some states do not allow a manufacturer to exclude or limit
incidental or consequential damages and, therefore, the above exclusion may not apply.
Some states do not allow limitations on how long an implied warranty will last. It is possible that the above limitation may
not apply. This warranty gives the original purchaser specific legal rights. The original purchaser may also have other legal
rights, which vary from state to state.
Warranty of Service: To obtain warranty service, the original purchaser must return the Mudd-Ox vehicle to the local au-
thorized dealer or service center, inform them of the warranty, and provide proof of purchase before any warranty service
can be provided. The authorized dealer or service center will inspect the product to determine what repairs or parts are
needed and whether they are covered under this warranty. To locate an authorized dealer or service center, please call
Mudd-Ox at [phone] or visit Mudd-Ox online at www.muddox.net

Safety
Safety Equipment
All occupants must wear a DOT-certified helmet. Standard are seat belts for the front two passengers, optional rear
with Twin Roll Bar and Seat - Bench. Use the seat belts at all times on land and ensure the ROPS (roll over protec-
tion system) system is in the upwards position with all pins and bolts correctly installed. Any time the vehicle is in
water, you must remove your seat belt and helmet, and wear a life preserver.
General Safety
Do not operate on public roads. Do not operate in waters with current or open water such as large lakes and oceans.
Do not refuel the machine with the engine running. Do not operate the Mudd-Ox on angles greater than 25 degrees.
Do not drive faster than conditions or your ability allows. Do not attempt to make sudden sharp turns or go from
forward to reverse abruptly; doing so could upset the machine or at the least jostle the occupants, possibly causing
injury.
Read through this entire manual and complete all necessary inspections, maintenance and parts replacements as
necessary.
• Do not operate this vehicle while intoxicated.
• Wear appropriate clothing: dress for weather conditions.
• Operator must be at least 16 years of age.
• Use common sense at all times while operating.
• Always have a first aid kit and fire extinguisher inside the vehicle.
• All passengers must be seated while the vehicle is in motion.
• Do not overload the vehicle under any circumstances.
• Ensure floor boards are in place while operating vehicle.
• Avoid blacktop when possible.
• Drive vehicle at safe speeds for terrain conditions.
Capacities of the Mudd-Ox
See Specifications for information on Mudd-Ox vehicle and Amphibious Trailer capacities. Under no circumstances
should the maximum capacities be exceeded. Subtract weight of all accessories from total vehicle capacities. Al-
ways evenly distribute weight to prevent imbalances.
Prepare Your Trip
The Mudd-Ox is capable of traveling to remote locations where emergency services are not readily available. These
locations can range from desert to tundra climates. When traveling in the Mudd-Ox, always pack a survival kit suit-
able for all occupants in the vehicle. This includes but is not limited to: food, water, extra clothing, fuel, flashlight,
portable heater, tent, flares, tools, spare parts, and spare tires mounted on rims. Never venture into remote areas
alone, and notify someone of your departure and expected arrival time. Create emergency plans in advance.

12
Safety Cont.
Every operator MUST review and understand the basic operation manual and all warning labels displayed on this
page and on the vehicle before operation. Please keep a copy in the glove box for operators to review as needed.

Wind chill is the feeling of colder temperatures than what the thermometer reads. This happens when the wind
blows cold air across exposed skin.
All Mudd-Ox operators and passengers must be aware of the wind chill factor. Always dress properly for the weather
and cover exposed skin. Ensure young children are adequately dressed for cold temperatures. It is best to bring candles
and blankets in case of emergency. For colder applications, we highly recommend installing either our Cab - Canvas or
Cab - Aluminum (Figure-1, 2) with a heater (Figure-3). For warm climates we recommend the A/C Unit (Figure-4).

Emergency Bypass
The bright red switch on the instrument panel is for emergency use only. It is designed to override preliminary
startup procedures to quickly start the vehicle. By holding the switch in the “ON” position, it will bypass the need for
control levers to be in neutral, and will bypass the parking brake. Once again please note this is for emergency use
only. Using this switch without care could cause the vehicle start and immediately move depending on operator
stick location.
Engine Startup
Insert key. Turn completely clockwise to start engine, release once started (If the engine fails to start after 5 sec-
onds, turn off the key for 5 to 30 seconds and then try again). Turn counterclockwise to shut off engine.
Engine Throttle
For easy of driving, Mudd-Ox XL is designed with a push button throttle system. Once the engine is started, simply
press the rabbit symbol for higher RPM, and the turtle for lower RPM. Full throttle will give you full power and
torque. Half throttle will give you half power and torque, etc. The more you apply the throttle, the more power and
speed you will be able to achieve. Note: It is not recommended to drive the Mudd-Ox under 2000 RPM.
Control Levers
You will use the two control levers to change direction of the machine. The left lever “A” operates the left side
wheels/track, and the right lever “B” operates the right side wheels/track (Figure-1). Please note that smooth
minor movements on the controls are all that is needed to drive the Mudd-Ox.

Drive the Mudd-Ox Cont.
Neutral
When both levers are in neutral position, the Mudd-Ox will not move in either direction. If parked on an incline, it
may begin to slowly creep. Always follow safety precautions as explained throughout this manual.
Forward
Pushing the control levers forward will drive the wheels/track forward. The further the levers are pushed, the
faster the Mudd-Ox will travel.
Reverse
In reverse, each lever will still control its respected side of the Mudd-Ox. Pulling them backwards will drive the
wheels/tires backwards. The further the levers are pushed, the faster the Mudd-Ox will travel.
Turning
As the XL utilizes a hydrostatic system, it can turn 360 degrees. A left turn can be achieved in numerous ways:
• Left side lever in neutral position while pushing forward on the right side lever (wide radius turn).
• Left side lever in reverse position while pushing forward on the right side lever (360 degree turn).
The above works vice versa for completing a right side turn. Practice driving the XL in an open, safe environment
before operation in more demanding areas.
Climbing Steep Hills
When climbing a steep in hill the Mudd-Ox, ease back on the control levers. This system is designed to provide
maximum power and torque to prevent engine bogging or stall. If the engine continues to bog down, slowly pull the
levers closer to neutral position until it gains power. Use precise movements.

Land Operation
Vehicle Preparation
Before operating the Mudd-Ox, complete the following vehicle preparation:
•Complete vehicle maintenance as described throughout this manual.
•Ensure all floor boards and engine cover are secured in place to keep foreign objects out of the drivetrain.
•Place roll bar in the “up” position and verify safety bolts and clips are in place.
•Inspect fuel tank, fuel lines and fuel fill for potential leaks or spilled fuel. If there is any spilled fuel, immediately
clean and service vehicle before further use as serious injury may occur. Use the fuel gauge located on the dash
to ensure the fuel tank is full.
•If at any time during operation there is an unusual noise, sound or smell coming from the Mudd-Ox, inspect im-
mediately.
•Ensure the weight capacity is not overloaded, and distribute weight evenly.
•Load enough supplies to last in case of emergency.
Occupant Preparation
• If applicable, the front passenger must properly adjust the grab handle (Figure-1) by removing the pin and sliding
the T-bar in/out. It should be close enough to reach with both hands, but not pressing against the passenger’s
body. Verify the safety pin is secured properly reinstalled.
• Passenger must hold onto the bar at all times. Rear passengers must locate the grab rails and hold onto them at
all times (Figure-2).
• All front occupants must wear seat belts, rear occupants if seat belts equipped, and all wear DOT-rated helmets.

Land Operation Cont.
Turning Radius
It is important to always check your surroundings before turning the Mudd-Ox. Look for objects such as trees and
rocks, changes in terrain elevation, and other people. XL is capable of turning 360 degrees within its own radius via
counter-rotating its wheels. Never counter-rotate or sharply turn the Mudd-Ox at high speeds or on harsh terrain.
Steep Grades
Never operate the Mudd-Ox over 25 degree grades or on side slopes. Check your specific engine manual to read
manufacturer’s recommendations on maximum grade. Do not make sudden adjustments or put the Mudd-Ox into
a neutral position, as the vehicle can lose control and roll down the hill where severe injury or death can occur.
When approaching or descending grades, always drive head-on to prevent upsetting the vehicle. Maintain control
of the vehicle. Always drive slow and gentle to prevent loss of traction.
Mud and Snow
Always survey an area before driving the Mudd-Ox into unusual terrain. On soft grounds including but not limited
to mud and snow, remain cautious about bottoming out the vehicle. This occurs when the Mudd-Ox tires or tracks
are no longer touching the ground, and rather the machine is resting on the lower body. Often times it is caused by
driving into deep ruts or too deep of snow. Always look for alternative routes if you encounter these circumstances.
Winter
Mudd-Ox is capable of operating in cold climates. Check the engine manufacturer’s manual for information about
cold weather and if applicable, preheating the engine. We recommend equipping the machine with a top and heat-
er system. Occupants must take necessary precaution as explained under Safety. It is important to never allow
water to fill inside the lower body, as it may freeze and seize the driveline.
Desert
Similar to cold temperatures, desert climates also require additional precaution. See Instrumentation Panel for
information on vehicle temperatures. Never exceed the written temperatures as well as engine manufacturer’s
recommendations. Always bring plenty of water and additional resources for all occupants. It is recommended to
install a Cab - Canvas with the side curtains rolled up to allow for maximum shade and air flow to occupants.

Water Operation
Drain Plugs
Located at the bottom rear of the Mudd-Ox are (2) drain plugs (A in Figure-1). Before driving into water, always
ensure the drain plugs are tight by turning them clockwise (Figure-2). This will prevent water from leaking inside
the machine.

Vehicle Preparation
• Complete the vehicle preparation procedures as described in Land Operation.
• Ensure there are no punctures in the lower body.
• See Bearings for information about inspection and servicing.
• Ensure the bilge pump works and is free of debris (Figure-4).
• Ensure the weight capacity is not overloaded, and weight is distributed evenly.
• Bring a paddle in case of emergency.
• Remove plow if equipped.
• Never venture into water without a safety crew on shore.
• Keep a bucket in the vehicle for draining water.
• Equip the vehicle with a winch.
• Keep electronic devices in a floating storage unit.
• Inform others of your expected return time.
• Bring a satellite cell phone.
• Retract the passenger t-bar.
Occupant Preparation
All occupants must unlatch their safety belts before entering water, remove DOT-certified helmets, and wear flo-
tation devices. If the Mudd-Ox is equipped with Cab - Aluminum, locate the exit areas and side door latches. If the
Mudd-Ox is equipped with Cab - Canvas, unzip the doors and roll them up. Make sure all occupants know the ve-
hicle exit locations in case of emergency. If there is an emergency, all occupants are to leave the vehicle as quickly
as possible and get to safety
Entering Water
Mudd-Ox can only be used in calm water. Drive slow and steady. Only enter water at an angle of 10 degrees or less
to prevent water from flowing into the Mudd-Ox. Stay near the shore. Do not operate in waters with current or
open water such as large lakes and oceans. Only enter water if the Mudd-Ox is equipped with tires or tracks with
swimming capabilities, or if outboard motor is installed. See outboard motor owner’s manual for information. Do
not enter water with plow installed. Vehicle will become unbalanced and dangerous.
