Triple Flail Operation Section 3-4
OPERATION
The rear mower height is controlled with the 3-point hitch control lever. Follow
the instructions for this control is the tractor operators manual. The tilt of the rear
mower is controlled with the third spool if the lift valve and is coordinated as shown
above.
The left and right mower on/off switches are mounted to the four spool valve or
the cable controls for cab and non-cab units respectively. Read and follow the
mower operation section closely for instructions on how to operate them.
This machine may be equipped with an auxiliary oil temperature gauge, an amp
gauge or oil pressure gauge. If oil temperature reaches 200 degrees Fahrenheit,
stop mowers and see trouble shooting section for possible causes. Keep an eye on
all gauges for indication of problems.
MOWER OPERATION
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.
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 prior to mowing can help eliminate these potential 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. Bring the R.P.M. of the tractor up to
1200 and engage the side mower. If a rear mower is being used, allow the R.P.M. to
return to 1200 before engaging the rear mower.
The flail mower deck should be carried so that part of the weight is carried be the
ground roller. When the flail is carried this way, the roller also follows the contour of
the ground more easily during mowing operations.
When cutting small shrubs or brush, begin each pass at the top of the material
and work down with each consecutive pass. Use a low speed to allow the cutting
blades time to mulch as well as cut the foliage. When the initial pass has been
made, disengage the mower and return the mower to the travel position. Return to
the starting point and make next pass, etc. The flail head is not intended for cutting
heavy brush, or for continually cutting brush. Wear or damage of the blades will
occur rapidly when the flail cutter is used this way.
To ensure a clean cut, engine speed should be maintained at approximately 1800
– 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.
