This handbook describes the use, maintenance instructions
and spare parts supplied for the indicated plough.
The farming implement known as “plough“ is designed to
work the soil, linked to a tractor with lift and universal 3-point
coupling.
Regular and satisfactory operation together with economic
and long lasting use of the implement depends on compliance
with the instructions given in this handbook. It is, therefore,
advisable to strictly comply with the following instructions in
order to prevent faults which could jeopardise the correct and
long-lasting operation of the implement.
Compliance with the instructions in this handbook is also
important
since the Manufacturer declines all and every
responsibility caused by negligence and failure to comply
with these instructions.
The Manufacturer shall, however, remain at the customer’s
disposal for immediate and thorough assistance together with
anything else that may be required in order to ensure the correct
operation and maximum efficiency of the implement. The
Manufacturer reserves the right to make any modifications and
improvements to the implement, as may be considered
opportune, without being obliged to immediately inform the user.

3. PROTECTION SYSTEMS
The different auto-reset protection systems (leafspring / rubber
dampers) work automatically. When finding any obstacle, the system
alllows the tine to trip up and overcome it then returning to its working
position without stopping the tractor.
In this way, all impacts caused by irregularities on the field are
absorbed by the protection system which, therefore, protects all of the
elements on the equipment as well as on the tractor.
Also because of this reason, the auto reset protection systems
decreases the required pull power as they prevent the tractor from
ripping all obstacles that the field may present to an even work.
Note: Ovlac´s auto reset protection systems are set at the
factory at an optimal pressure for average soils.
4. SET TO WORK
4.1 4.1 –HITCHING TO THE TRACTOR
Ovlac equipment are designed to fit the universal 3-point linkage of
any tractor
The cross shaft is supplied in two versions (center-to-center
distance): - Category II 870 mm
- Category III 1.010 mm
Before hitching the equipment, check the following:
- The lower links of the tractor are adjusted at the same height and
length.
- The wheels of the tractor have identical air pressure. This
pressure must be according to the manufacturer´s instructions
- The lower links of the tractor must be centered and allow for a
small oscillation

4.2 –ALIGNMENT
The plough should always work in line with the tractor. If not, the
tractor will tend to leave the furrow course. Check that lengths A1=A2
(Fig. 2)
Crabbing is corrected automatically in OVLAC ploughs thanks to
their oscillating cross shaft. In ploughs with fix coupling, act on the
drifting-correction turnbuckle (hydraulic in option).
The third point should be linked so that the end linked to the
plough be slightly higher than the one linked to the tractor (Fig. 3)
The third point should always be placed in the oblong hole E (Fig.
3), trying that its length does not hinder it to move while working.

INCORRECT
4.3–OTHERS ADJUSTMENTS
The length of the third point should be adjusted so that the frame
works in a parallel position with respect to the field since, if not, the first
bodies would plough at a different depth than the rear ones achieving
an uneven labour (Fig. 4).
For the same reason, check that the beams work vertically to the
field (Fig.5). To achieve this, make sure that the lifting arms of the
tractor are at the same height and act on the adjusting bolts A at the
headstock (Fig. 6).
IMPORTANT:
Care should be taken not to take curves at work,
especially with very wide tools, because the effort lever can cause
serious damage to the structure of the machine.

5. WORKING DEPTH
The depth of work is regulated by the roller, by means of bolts of
regulation A (Fig 7). In any case the working depth is such that
bushings discs are not left at a suitable distance from land, noting that
they never reach the ground.
6. TRANSPORT
In foldable machines, the side frames must be folded in
hydraulically for transport in order to carry the machine in its
minimum width.

10
7. MAINTENANCE
Retighten all bolts and nuts after the first 8 hours of work, specially
the ones of mouldboards, shares and points. Henceforth, check every 100
hours of work. When putting the plough away, clean and grease
thoroughly the mouldboards to prevent from rusting.
Lubrication: grease the greaser.
Safe maintenance
Be used to the maintenance procedures before carrying out the
works. The working zone must be clean and dry. Don’t carry out any work
of lubrication, repair or adjust with the motor enabled. Keep the hands,
feet and clothes always far from movable components. Turn all the
controls off, to alleviate the pressure. All the components must be in good
state and correctly installed. Repair damages immediately. Change any
worn away or broken pieces. Maintain all the components of the machine
clean of fat, oil and accumulated dirt. Because of being dragged
equipment, disconnect the cable groups of the tractor before making
works of weld in the machine.
Take care of the leaks of high pressure
The fluids that escape of the system can have as much force that
they can penetrate the skin, causing serious injuries. Therefore, it is
essential to leave the system without pressure before relaxing or
disconnecting any pipe and make sure that all the connections and the
hydraulic parts they are well tight before applying pressure to the system.
In order to locate a hydraulic oil leak, use a piece of cardboard that is put
on the connections. Do not approach the hands and the body to a leak of
high pressure. If, in spite of this precaution, it happens an accident, go
immediately to a doctor who should eliminate surgically the fluid within few
hours to avoid gangrene. The doctors who do not have experience in
dealing with these type injuries can go to a specialized medical centre.
Storage of the hydraulic sleeves.
IMPORTANT:
maintain the plugs clean. The abrasive particles, like
the sand or the metallic shaving, can damage the oil seals, shirts and
cylinders, causing internal leaks. Once disconnected of the tractor, make
sure that they are not in contact with the ground
