The sickle bar is fitted with a safety device for protection
against obstacles. If this device is tripped by impact with an
obstacle, stop the tractor without raising the cutting arm.
Check that the cardan shaft has not become seperated, if
so, reassemble it. Position the safety tie rod parallel to
the ground, and reverse the tractor until the safety tie
rod hooks up again. If the tie rod releases easly, adjust
spring (O, Fig. 31) using nut (P, Fig. 31 which should be
tightened half turn at a time.
For successful mowing and to avoid jamming, we advise you
to:
Set and maintain the power take-off at a constant rate
of 540 rpm to ensure correct blade frequency;
Compatibly with the soil conditions and the type of grass,
maintain a steady work speed: no slower than 5 mph to favor
the discharging of the mown grass and no faster than 6.2
mph to avoid breaking or damaging the machine's structure.
If the grass is tangled or flattened, keep the cutting bar grazing
the ground.
Hazard bar
The hazard bar has been included with the equipment of the
machine for safety reasons, to indicate the space occupied
by the mower at work. For working, position the hazard bar
in position (Q1, Fig. 32) and lock it in place with the screw
(R). For transport put it in position (Q2).
