Cheetah Operation Section 3-11

OPERATION

The mower will operate more efficiently in tougher conditions and with less power

if the knives are kept sharp. If the mower begins to vibrate, stop the tractor, check for

wire wrapped in the spindle or damaged knives. When replacing knives, replace all

knives with new knives and bolts to ensure proper balance so the mower will not

vibrate. Severe vibration will result, if knives with unequal wear are used.

DO NOT use excessive force when positioning cutting head into heavy

branches or stumps. Damage to the unit may result. It is best to let the

cutter head “eat away” slowly at heavy cutting jobs.

If foliage falls on top of mower deck causing tractor to become unstable,

push the joystick control “Forward” and to the “Right” to relieve tipping

of the tractor. Lower mower deck to ground and shut down unit. After

all motion stops, remove foliage from mower deck.

The Cheetah Rotary mower was designed for cutting brush and foliage up to 4

inches in diameter or mulitple branches that have a total cross section area equivalent

to one 4 inch branch. Cutting multiple limbs at the same time may overload the mower,

causing it to slow down or stall. Regardless of the size of material being cut, the speed

of the cutter head must be maintained. To ensure that the cutter head is running at

maximum speed, run the tractor at 2400 RPM during mowing operations. If the cutter

head slows to the point that the knives are folding back, move the mower head away

from the foliage and allow the cutter head to regain full speed.

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 cheetah rotary cutter head is designed for clockwise rotation

(clockwise as seen from the top of the cutter head). Never operate the

cutter head with a counterclockwise rotation. Operating the mower

with a counterclockwise rotation will cause objects to be thrown

towards the tractor!

To ensure a clean cut, engine speed should be maintained at approximately 2200 –

2400 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.

For cutting brush it is usually best to stop the tractor and swivel the boom and

mower into foliage. 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.
