Operation Section 3-13
OPERATION
The 50” boom flail equipped with free swinging brush knives is intended
for brush cutting only. Cutting grass is not recommended.
Do not allow knives to cut down to the ground. Position ground roller to
maintain knife arc at a minimum of 2 inches above the ground. Knife
contact or lug contact with ground will cause permanent damage to cutter
shaft, knives, and knife attachment parts.
50” BOOM FLAIL
The 50” boom flail mower was designed for cutting brush and foliage up to 2 inches
in diameter or multiple branches that have a total cross section area equivalent to one 2
inch branch. Cutting multiple limbs at the same time may overload the mower causing
it to slow down or stall completely. Regardless of the size of material being cut, the
cutter shaft speed must be maintained. To ensure that the cutter shaft is running at
maximum speed, run the tractor at full throttle during mowing operations. If the cutter
shaft slows to the point that the knives are folding back, move the mower head away
from the foliage and allow the cutter shaft to regain full speed.
Operating the mower in a manner that allows the knives to continually fold
back or allowing knife lugs to contact foliage will cause permanent
damage to the cutter shaft drum, knives, and knife attachment parts.
The 50” boom flail cutter shaft is designed for standard rotation (same
rotation as the tractor wheels during forward travel). Never operate the
cutter shaft in reverse rotation. Operating this mower in reverse
rotation may cause objects to be thrown out the front of the mower head.
Operating the mower in a manner that allows the cutting knives to
continually fold back will cause permanent damage to the knives, rotary
disk, and spindle assembly.
The Heavy Duty Rotary cutter head is designed for clockwise rotation
(clockwise as seen from the top or the currer head). Never operate the
cutter head in the counterclockwise rotation. Operating this mower in
counterclockwise rotation may cause objects to be thrown towards the
tractor.
