STORAGE SAFETY INSTRUCTIONS

The Cultivator is delivered equipped with a P.T.O. driveshaft with slip clutch and related operating
manual. When the machine is delivered, check that there is no damage to the Cultivator or
driveshaft. In case of damage or missing parts immediately notify Wessex International or your
Dealer.
Because of his size, the machine could be delivered with some parts to be assembled.
In this case, the assembly of such parts is an owner’s task, and must be performed carefully, with
reference to the tables of the Spare parts section.
WARNING
For proper tightening torques of bolts and screws, refer to the table in this manual.
LOWER HITCHES POSITIONING
The Cultivator is designed to be mounted on tractors equipped with:-
•3-point Hitch Category I (ISO 730 standard).
•3-point Hitch Category II (ISO 730 standard).
The position of the lower hitches must be adjusted accordingly.
If the tractor is equipped with a 3-point Hitch Category I (ISO 730 standard):-
• Verify that the lower clevises are equipped with I Category pins, so that the distance between
upper and lower pins is 18" (460mm approximately), as required from the standard (see figure
below).
• Verify that the lower clevises on the square tube are at a distance of 13 7/16" from the centre of
the Cultivator PTO. The clevises shall be positioned equally from the PTO, at a distance of 26
7/8" (683mm) see figure below:-
•Loosen the U-bolt clamping the clevis to the square tube.
•Slide the clevis on the square tube, positioning it at a distance of 13 7/16" from the centre of the
Cultivator PTO. At the end of the operation the clevises should be positioned symmetrically from
the PTO at a distance of 26 7/8".
•Re-tighten the U-bolt, referring the the tightening table of this manual.
15
SET UP

If the tractor is equipped with a 3-point Hitch Category II (ISO 730 standard):-
• Verify that the lower clevises are equipped with II Category pins, so that the distance between
the upper and lower pins is 24" (610mm) as required from the standard (see figure below).
• Verify that the lower clevises on the square tube are at a distance of 16 1/4" from the centre of
the Cultivator PTO. The clevises should be positioned symmetrically from the PTO, at a
distance of 321/2" (825 mm) - see figure below.
To adjust , proceed as follows for each of the two clevises:-
•Loosen the U-bolt clamping the clevis to the square tube.
•Slide the clevis on the square tube, positioning it at a distance of 16 1/4" from the centre of the
Cultivator PTO. At the end of the operation the clevises should be positioned symmetrically from
the PTO, at a distance of 321/2".
•Re-tighten the U-bolt, referring the the tightening table of this manual.
16
SET UP

To connect the Cultivator to the tractor the operator must do the following:-
•Drive the tractor in reverse, up to align the rear lifting arms to lower hitches of the Cultivator in
parking.
(see picture below);
•Set the tractor’s parking brake, stop engine, remove the ignition key and get off the tractor;
•Connect the lifting arms of the tractor to the lower hitches of the Cultivator, and the 3-point top
link to the upper hitch of the Cultivator, through the use of the pins and the relative safety split
pins;
•Raise the Cultivator until P.T.O.s of tractor and machine are at the same height, then adjust the
3-point top link so that the front of the machine is levelled to the back (the axis of the Cultivator
P.T.O. must be parallel to the ground), in order to limit stress transmitted to the Cultivator
through the cardan shaft;
•Make sure that left side of the Cultivator is levelled with the right, by adjusting the tractor lifting
arms, then lock the arms to prevent swinging that could compromise the stability of tractor and
machine;
•Finally adjust the parking stand, placing it at the highest point by means of the related elastic pin.
17
CONNECTING TO THE TRACTOR

Before installing the driveshaft, the operator must read the manuals of driveshaft and tractor,
checking in particular that rpm and direction of rotation of the tractor P.T.O. match those of the
Cultivator.
If the direction of rotation of the PTO tractor does not match that of the Cultivator contact the
Manufacturer or your Dealer.
To connect the driveshaft to the tractor and implement, the operator must:-
•Park tractor and Cultivator on a flat surface, with parking brake set, engine off, and ignition key
removed.
•Check that the safety devices of driveshaft,Cultivator and tractor are in good condition, otherwise
they must be replaced.
•Remove the P.T.O. shield of the Cultivator through the fixing screws.
•Position the driveshaft with clutch towards the implement side.
•Insert the clutch hub on the Cultivator P.T.O., then ensure it is tight on the shaft through its
fastener.
•Replace the P.T.O. shield of the Cultivator through the fixing screws;
•Insert the driveshaft yoke on the tractor P.T.O., then ensure it is tight on the shaft through its
fastener.
•Hook to the tractor and Cultivator the two retaining chains of the the driveline shielding, to
prevent shielding rotation during operation of the machine.
DRIVELINE LENGTH CHECK
Before operating the Cultivator, ensure that the size of driveshaft is adequate. The driveshaft
supplied with the machine has a standard length, therefore it may need the length adjusted,
depending on the tractor which the Cultivator is attached to.
The length of the driveshaft must be such to:
• Avoid bottoming out of the transmission tubes, when the driveshaft is in compressed position
(when Cultivator is raised up off the ground).
•Ensure an overlapping of the transmission tubes enough to transmit the torque required, when
the driveshaft is in max extension (when Cultivator is in its lowest position in the ground).
When the driveshaft is at its minimum length (max compressed position), there must be at least
2cm between the ends of each transmission tube and the yokes side.
When the driveshaft is at its maximum operational extension, there must be an overlap between
the tubes profiles of 15 cm at least.
