Description of the sickle bar mower
This agricultural implement can only operate by means of
a cardan shaft applied to the pto of an agricultural tractor
equippedwith liftanduniversal three-pointhitch. Sinceitis
movable, the mowing machine can be easily mounted on
tractors with different gauges or on tracked vehicles (Fig.
1). The two-motion tooth-blade system used in mowing
machines, makes possible a scissors cut which leads to
a higt speed operation on a any crop. The original tooth-
blademotion guaranteesasharpandclean cutonanytype

absence of soil which this mowing system does not raise,
sharp because the stems are not frayed. The sickle bar
may also be used with the cutting arm tilted for working on
canals, ditches and embankments (Fig. 2 and 3).
ATTENTION
The sickle bar is suitable only for the uses
indicated. Any other use different from that
described in these instructions could cause
damage to the machine and represent a se-
rious hazard for the user.
Itistherefore advisableto strictlycomplywith thefollowing
instructionsinorder toprevent faultswhichcould jeopardi-
zethecorrect andlong-lasting operationofthe implement.
Compliance with the instructions in this handbook is also
important since the Manufacturer declines all and eve-
ry responsibility for damage to persons or property
caused by negligence and failure to comply with these
instructions.
The Manufacturer shall, however, remain at the custo-
mers’ disposal for immediate and thorough assistance
together with anything else that may be required in order

Installing sickle bar on tactor
The sickle bar can be hitched to I, II or quick coupler cate-
gory tractor equipped with a universal three-point coupling.
DANGER
Application of any implement to a tractor is
a very dangerous operation and must only
be carried out with the utmost care in com-
pliance with the instructions.
The correct tractor/sickle bar position is established by
setting the implement at such a distance from the tractor
that the universal coupling remains 2-4 inches from its ma-
ximum closing position. Now proceed in the following way:
1. Back tractor into position and align draft links (A, Fig.
6) with draft link brackets on sickle bar.
CAUTION: Before you work around hitch:

2. Connect the upper third-point and correctly regulate by
means of the adjuster (B, Fig. 7). Place plate (C, Fig. 7)
at the left side of the hicht integral with the same pin.

split pins (G Fig. 8)
4. Lock the lift links using the relative chains (I, Fig. 7)
and couplings parallel to the tractor. This operation must
be carried out to prevent the machine from moving in a
horizzontal direction.
5. Install PTO shaft to tractor (Fig. 9).
IMPORTANT: Sickle bar mower MUST BE level front
to rear.
Make sure PTO shaft is locked on the tractor PTO prior
to engagement (L). Check that the guard (M) is free to

should be followed; these prescribe that at least 20% of the weight of the tractor alone should be
borne by the front axle and that the weight on the arms of the hoist should not be more than 30% of

(lifter), in conformity with applicable standards.
2) The class of the equipment attachment pins must be
the same as that of the lifter attachment.
3) Take care when working within the range of the lifting
arms as this is a very dangerous area.
4) Be very careful when hooking and unhooking the
equipment.
5) It is absolutely forbidden to stand between
the tractor and linkage for acting the lifting
controls from the outside (Fig. 18).
6) Itisabsolutely forbiddento standinthe spacebetween
the tractor and the equipment (Fig. 18) with the engine
running.
7) The attaching of additional equipment onto the tractor
brings about a different distribution of weight on the
axles. Check the compatibility of the tractor performance with the weight that the mower transfers
onto the three-point linkage. If in doubt consult the tractor Manufacturer.
8) Comply with the maximum admissible weight for the axle, the total mobile weight, transport regu-
lations and the highway code.

Adapting the sickle bar mower
To ensure optium use, the sickle bar must completely
projectfrom thetractor(Fig.20);three situationsareshown
in the Figure 21:
1) hitching to a tractor normally used for mowing jobs;
2) hitching to a large tractor;
3) hitching to a small tractor or to certain types of tracked
vehicle.
Adjustment
Before starting a mowing session, adjust the machine so that the best working setup is obtained.
Correctmachinesetup guaranteesexcellent mowing,allowsfor thebest machine-tractorperformance
and remarkably reduces wear of the cutting blades.

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 se-
perated, 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 (T, Fig. 31) using nut (U,
Fig. 31) which should be tightened half turn at a time.
ATTENTION
A spring compression other than that indicated in Figure
31 (0.59 inches) can make the safety device ineffective.
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;
maintain an engine speed of 1800÷2000 rpm.
 FRPSDWLEO\ZLWKWKHVRLOFRQGLWLRQVDQGWKHW\SHRIJUDVV
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 machi-
