Owner Information
Thank you for your decision to purchase a Bad Ax Disc
Mulcher from Loftness. To ensure maximum performance
of your machine, it is mandatory that you thoroughly study
the owner’s manual and follow its recommendations.
Proper operation and maintenance are essential to
prevent injury or damage and to maximize machine life.
The Loftness Bad Ax Disc Mulcher is an effective, reliable
machine ideally used for land clearing, vegetation control,
forest fire prevention and more. The 60 inch diameter
disc can cut down trees up to 14 inches in diameter with
a maximum material size of 6 in. (15.2 cm) allowed above
the disc. For best results, operate the machine as low to
the ground as possible without the teeth striking ground
or other obstructions. Lifting or tilting the disc mulcher
increases the risk of flying debris. Because of the high
speed of the disc, the life of the teeth will be reduced
if it is operated in rocky terrain or in areas where many
obstacles are present. Areas to be cleared should be
free of debris such as rocks, bottles, large branches etc.
The teeth cut and pulverize the grass, weeds, brush and
small trees.
Operate and maintain this machine in a safe manner and
in accordance with all applicable local, state, and federal
codes, regulations and/or laws, and in compliance with
on-product labeling and these instructions.
Make sure that all personnel have read this owner’s
manual and thoroughly understand safe and correct
operating, installation and maintenance procedures.
Continuous improvement and advancement of Loftness
products may result in changes to your equipment
that may not be reflected in this publication. Loftness
reserves the right to make product improvements to the
machine at any time. Although great care has been taken
to ensure the accuracy of this publication, Loftness does
not assume any liability for errors or omissions.
Warranty Policy
Be sure to read and understand the Warranty Policy at
the beginning of this manual. It is also important that you
fill out the Warranty Registration form(s) completely with
your dealer so as not to void the warranty.
Serial Number Location
The arrows above indicate the location of the serial
number tag (1) and the location of the serial number
stamped into the frame (2).
Always use your model and serial number when
requesting information or when ordering parts.
Manual Storage
Keep the owner’s manual and the entire documentation
packet in the manual holder (1) provided on your disc
mulcher. Remove the two bolts (2) and remove the cover
(3) to gain access. The owner’s manual must be available
for all operators.

position in the machine. Before leaving the operator’s
position, disengage power to the attachment, shut
off engine and remove ignition key.

Hydraulic Safety
WARNING: Contact with high pressure
fluids may cause fluid penetration and burn
hazards. Fluid that is under pressure can
penetrate body tissue. Fluid penetration can
cause serious injury and possible death. If
fluid is injected into the skin, seek medical
attention immediately!
• Always wear safety goggles or glasses when working
on hydraulic system to avoid eye injury.
• The hydraulic system is under high pressure. Make
sure all lines and fittings are tight and in good
condition. These fluids escaping under high pressure
can have sufficient force to penetrate skin and cause
serious injury.
• Never check for leaks by using any part of your body
to feel for escaping fluid.
• To prevent serious personal injury from escaping
high pressure fluid, never attempt to inspect, service
or disassemble any part of the hydraulic system until
all pressure has been relieved from the system.
