OPERATING THE CULTIVATOR
5.2. OPERATION OF THE CULTIVATOR WITH THE
HYDROPACK COUPLED TO A SEEDER
The cultivator fitted with the hydropack can be coupled with a seeder
by the three-point hitch. The hydropack position is shifted from transport
to service by a hydraulic actuator. In order to set the proper service
position, adjust the TPH upper link. Adjust during the first pass. Secure
the cultivator in the transport position as shown in Fig. 11.

5.3. CULTIVATOR HYDRAULIC SYSTEM
•
When the cultivator is running, its hydraulic system is under high
pressure.
•
Inspect all hydraulic lines each time before work and replace them
every 6 years.
•
Use only the oil grades recommended by the manufacturer. Do not mix
oils of different grades!
•
Verify that the tractor hydraulic system is depressurized before
connecting with the machine hydraulic system. Keep the hydraulic
quick-release couplings clean at all times.
•
If the hydraulic system is damaged, hydraulic oil may leak out. Have
the system repaired by qualified personnel.
•
Return waste hydraulic oil to an authorised disposal point.
•
The oil purity grade in the tractor hydraulic power system must meet
the 20/18/15 requirement according to ISO 4406-1996.
If injured by high-pressure jets of hydraulic oil,
immediately seek medical attention. If the hydraulic
oil contaminates the eyes, flush the eyes with plenty of
water and seek attention of an ophthalmologist. Wear
adequate protective clothing at work.
ATTENTION!
5.4. FINISHING THE WORK WITH THE CULTIVATOR
Place the machine on a hard, flat, level ground. Disconnect the
electrical power supply (if the optional lighting system is installed) and
the hydraulic supply line. Disconnect the 3-point upper link and the
tractor lower links. Before a long period of storage the cultivator should
be cleaned and all malfunctions should be repaired; also verify the
paint coat. If it is required to make some touch-ups, it is advised to use
the paint repair kit supplied by the manufacturer. Protect the machine
against weather conditions.
