Mowing Instructions

!WARNING

Prolonged exposure to high sound levels require hearing

protection. Wear hearing protection when operating this

machine with open platform tractors.

Allow a fewminutes for oil to spread in the cutter bar

beforeengaging the PTO when changing from transport to

operating position.

With the cutting bar on the ground,engage the PTO at low

tractor idle and accelerate gradually to 540 rpm PTO

speed.

If the cutter bar is operated at an angle for long periods of

time, hold it horizontal fora few minutes every half hour or

so of work to help lubricate gears at upper end of cutter

bar.

Adapt forward speed to working conditions. Gear down

when mowing in dense crops. Do not lower tractorr pm.

Adverse Field Conditions

!DANGER

Do not use machine in rocky or stony conditions.

Extra care and precaution should be taken in rough or

debris-ridden ﬁelds. The following adjustments should be

made to the mower in these conditions to minimize the

possibility of foreignobjects being deﬂected by the cutting

blades.

1. Tiltthe angle of the cutter bar back towards the

horizontal position by lengthening top link to raise the

cutting height of the knives.

NOTE: Before using the mower, check the break-

away linkage to make sure all components work

correctly.

NOTE: Although the mower is shielded to prevent

objects from being thrown by the blades, no one

shield is 100% effective. As a rule most people are

not knowledgeable of the dangers of being around a

disc mower while it is in operation. Therefore, the

operator should alwaysstop mowing when someone

passes by.

2. Reducethe forward speed.

3. Makesure the cutting blades can pivot if an

obstruction is hit.

!CAUTION

Do not disengagePTO when engine is at full PTO rpm. Always

idle engine before disengaging PTO.

The break-awaylatch allows the cutter bar to swing back if

an obstruction is hit. If the latch releases, stop the tractor

immediately,idle engine and disengage the PTO.

Toreset the cutter bar, back the mower slowly and

carefully until breakawaylatch repositions. The factory

setting of the latch is adapted to most working conditions.

Check the cutter bar for anydamage before resuming

operation.

If the cutter bar continues to break awayafter resetting,

the pressure of the spring assembly can be increased. In

all cases the length must not be less than 3 3/8 inch or

safety disengagement cannot function.

The stack of spring washers should be compressed to

3 3/8 inch. See Figure 3-5.

IMPORTANT: If an obstruction is hit, idle engine,

disengage PTO,shut off tractor, remove ignition key

and wait for all moving parts to come to a complete

stop. Inspect the entire mower and repair any

damage before resuming operation.

IMPORTANT: ToSafety Break-Away avoid personal

injury, pick up all rocks and other debris before

mowing. Never assume an area is clear, so enter a

new area carefully. Cut material higher the ﬁrst time

to allow the mower to clear unseen objects.
