OPERA
TION
9.4 Mower Operation
The rotating parts in this machine have been designed and tested for rugged use. However, they could fail
upon impact with heavy solid objects-such as steel guard rails, concrete abutments,etc., causing them to be
thrown at a very high velocity. Never allow cutter head to contact such objects. Inspecting the cutting area for
such objects and removing them prior to mowing can help eliminate these potiential hazards.
Once on location, lower the mower deck slightly above the material to be cut, so the mower does not have to
start under a load. With the tractor at an idle, engage mower. Bring tractor R.P.M. up to 1900-2200 R.P.M. and
slowly
lower deck to ground level.
A flail mower deck should be carried so that the part of the deck weight is carried by the boom and part carried
by the ground roller, when moving on the ground. When the flail mower is carried this way, the ground roller
follows the contour of the ground more easily during mowing operations.
The rotary mower deck should always be carried rather than dragged on the skid shoes when mowing on the
ground. Dragging the rotary mower deck increases the side loads on the boom, decreases the horsepower
available to the cutter head, and reduces the ability of the accumulator the carry part of the weight of the boom
during mowing operations.
When rotating parts are in motion, serious injury may occur if caution is not used or danger is
not recognized. Never allow bystanders within
300 feet
of the machine when in operation.
Extreme care should be taken when operating near loose objects-such as gravel, rocks, and
debris. These conditions should be avoided.
9.5 50” & 60” Boom Rotary
The 50” & 60” boom rotary brush mower was
designed for cutting brush and foliage up to 6
inches in diameter or multiple branches that have a
total cross section area equivalent to one 6 inch
branch.
During mower operation, the hand throttle must be
used to maintain engine speed at 1900-2200 R.P.M.
This prevents radical changes in mower spindles
speed, reducing the possibility of cutter assembly
damage.
The horizontal positioning action of the boom is
designed to position the cutting head and provide a
limited pressure relief when excessive pressure is
applied to the boom. Do not force the cutting head
into heavy branches or stumps. Damage to the unit may result.
When using the rotary cutting head for trimming trees and shrubs, let the mower saw into them.
Do not lower the mower head down directly into a tree or stump. The mower blades are
designed to cut with the end, and misuse can cause damage to the blade and a hazardous
situation for the operator.
Powering the boom down, forcing mower deck onto ground may damage mower deck and it’s
attachment to the boom, creating a potentially hazardous situation.
To ensure a clean cut, engine speed should be maintained at approximately 1900-2200 R.P.M. If the tractor
slows to less than 1800 R.P.M., shift to the next lower gear. DO NOT ride the clutch, this will cause premature
clutch failure.
The engine should not be operated at any time at more than 2400 R.P.M. on the tractor
tachometer.
