OPERATION
disengage the mower, and return boom to a safe travel position. Return to starting point and make next pass,
etc.
After the first day of operation, all bolts should be checked and tightened securely. This should be done
periodically to ensure the bolts do not become loose and cause damage to the tractor or mower, or injury to the
operator.
When cutting trees and brush approach material
to be cut with the head perpendicular to material.
The cutting edge of the blades should be the
only elements in contact with material. The blade
bar should not contact with material. The mower
head and blades should be moved
perpendicularly into the material rather lowering
the mower head on top of material. If the blade
bar edges are gouged or rounded from wear, the
mower head is being used incorrectly in an
abusive manner. The blade bar is not intended to
cut material or to be a wear item like the blades.
Do Not allow the blades or blade bar to contact
the ground, rocks or solid objects. Contact with
the ground can result in rocks and solid objects
being thrown out from under the mower head
which can cause serious injuries to the operator
and bystanders. This type of operation can lead
to bent or broken blade bars, broken blade bolts
and broken blade bar assembly bolts which can
be dangerous to the operator and bystanders.
(OPS-R-220
8.5 60” Boom Rotary Grass Mower
The 60” boom rotary grass mower was designed for cutting grass only. The cutter speed must be maintained
for proper cutting. To insure that the cutter is rotating at maximum speed, run tractor at full throttle during
mowing operations. If cutter assembly slows to the point that the knives are folding back, mov e the mower
head away from the foliage and allow the cutter shaft to regain full speed.
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
grass. Damage to the unit may result.
When using the rotary cutting head for cutting heavy grass, let the mower saw into it. Do
not lower the mower head down directly into the heavy grass. The mower blades are
designed to cut with the end, and misuse can cause damage to the blades 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.
