DHM 7 DISC MOWER
OPERATION INSTRUCTIONS
Bush Hog’s latest edition of Hay Mower includes DHM7 Model with a mowing width of 7’ to meet the hay
production requirement of today’s farmers and ranchers. The mower is equipped with protective deflectors
and/or chain guards to prevent objects being thrown from the mower by the blades, however, no shielding is
100% effective. All shields, guards, deflectors, and chains equipped on the unit must be maintained on the
mower in good operational condition.
It is the operator’s responsibility to be knowledgeable of all potential operating hazards and to take every
reasonable precaution to ensure oneself, others, animals, and property are not injured or damaged by the
mower, tractor, or a thrown object. Do not operate the mower if passersby, pets, livestock, or property are
directly in front or to the rear of the unit.
This section is designed to familiarize, instruct, and educate safe and proper mower use to the operator.
Pictures in this section are for the purpose of explaining the operation of a rotary mower and are not
necessarily of an DM cutter. Some pictures may show shields removed for purposes of clarity. NEVER
OPERATE this implement without all shields in place and in good operational condition. The operator must be
familiar with mower and tractor operation and all associated safety practices before operating the mower and
tractor. Proper operation of the DM mower, as detailed in this manual, will help ensure years of safe and
satisfactory use of the mower.
