NEW MACHINE
PTO shaft
For transport purposes, the PTO shaft is dismantled and
must be refitted.
Lubrication and general
With the machine standing level ensure the following
preparatory
work has been done:
1. The gearcase filled to the level plug (A) (fig. 2) Capacity:
2l. Use SAE 90 oil.
2. The gearbox filled up to the level mark in the inside rod
(A) (fig. 3). Capacity 1,5 l.
3. All oil and grease points as indicated on p. 22 (Lubrication)
4. All nuts and bolts tightened. (Re-tighten after first hour’s
work)
SERIOUS DAMAGE CAN RESULT
FROM FAILURE TO CARRY OUT THE
ABOVE PROCEDURES

ATTACHING THE MACHINE TO THE
TRACTOR
The PTO drive shaft must be set to a safe working length to
ensure the male shaft does not “bottom“ or separate from
the female tube under all conditions of use and transport.
To determine the correct mounting position: with the
machine on a firm level surface the Depth Control equipment
should be adjusted until the gearbox input shaft is horizon-
tal (fig.5). Position the tractor at a distance from the machine
to give 150 mm (6“) minimum engagement of the male half
of the PTO drive shaft in the female tube when connected
to the tractor. This establishes the safe working length of
PTO drive shaft for connection to the tractor.
Position the tractor lower link ball joints in line with the
mounting pins. Connect the tractor lower links. Fit the trac-
tor upper link and secure. Attach the PTO dirve shaft to the
pressure plate by the studs and tighten the nuts. Attach the
PTO drive shaft guard chains to the tractor and machine.
Attach stabilizer bar or check chains to limit sway to 50 mm
(2”). Adjust tractor linkage to level machine laterally and
longitudinally (fig. 5 and 6). Before engaging the tractor
PTO, lift the machine on the hydraulic lift linkage until the
PTO dirve shaft attains an angle of 40 º and set the limit
stop on the hydraulic lift control quadrant. (fig. 5)
ATTENTION! : THE PTO DRIVE SHAFT
ANGLE MUST NEVER EXCEED 40º.
Finally check that during transport and use the PTO drive
shaft does not “bottom“ or separte and that the maximum
angle of 40 º is not exceeded. Should it not be possible to
obtain the aforementioned setting with your tractor, SEEK
ADVICE, it may be necessary to reduce the length of the
PTO drive shaft by cutting.
Depth control
Machines with roller (fig 6):
Adjust the roller height by means of the spindle (A) until the
required position.
It is also necessary to adjust the height of the levelling board
by means of the spindles (B) in order to get a correct and
regular soil flow.
In order to obtain a good result the machine should be
adjusted in horizontal position. By adjusting the length on
the 3rd point linkage, ensure that the lower profile in the
side plates is horizontal.
It is possible to offset the position of the roller, ensuring a
good overlap between the passes, without marking in the
field. Optionally the offset is made by means of a hydraulic
ram.
Machines with bed former (Fig.7):
On these machines the adjustment is made by adjusting
the height and the working angle of the bed former.
Modify the height by means of the spindle (A). In order to
make the correct adjustment it might be necessary to modify
the working angle. By moving the adjusting plate (C) the
working angle is changed and is possible to modify the
pressure on the soil. The plate (D) is then regulated in order
to close the bed former sides.
Is also possible to change the height of the side skimmers
(E) to regulate the incoming soil flow.
