3.10 HYDRAULIC SYSTEMS

Safety measures concerning the hydraulics:
1) When the hydraulic pipes are connected to the hydraulic
system of the tractor, make sure that the hydraulic systems
of the operating machine and the tractor are not under
pressure.
2) For hydraulic-type functional connections between the
tractor and operating machine, sockets and plugs must be
marked with colours, in order to prevent errors. It could be
dangerous if they were accidently confused.
3) The hydraulic system is under high pressure; due to the
risk of accident suitable auxiliary instruments should be
used when investigating possible leakage points.
System regulation:
The hydraulic systems provided come equipped with one-way
flow regulators (Fig. 37) which allow for the regulation of the
quantity of oil during opening or closing, depending on how the
regulators have been installed:
Flow from A to B, free;
Flow from B to A, choked (regulated).
o regulate, loosen the lock nut (1) and turn the knob (2). Once this
adjustment has been made, re-tighten the lock nut.
Make sure that the result of this adjustment does not cause
the rising or descent speed to damage the structure itself.
Never exceed the maximum admissible pressure for the
hydraulic system.

3.11 LOADING PLATFORM

Use of the loading (or hopper inspection rif. Fig. 38) platform is
only consented when the seeder is at a stand still, the wheels
and safety foot must be standing on level and stable ground
(preferably cement). Ensure that the safety foot has been secured
using the appropriate security pin. There may be one or more
safety feet on the planting unit depending on the model.

3.12 BEFORE STARTING WORK

Before starting, lift the supporting base elements.
Before parking the seeder, lower the supporting feet by carrying
out the operation in the reverse order.

3.13 DURING WORK

The seeder has been studied to allow a high sowing speed,
compatible with the type and surface of the ground.
Bear in mind that a variation in tractor speed does not lead to a
corresponding variation in seed sown per hectare.
Always work at a constant speed. Sudden changes in speed
may result in an uneven distribution of the product.
Maintain e seeding speed compatible with type and cultivation
of the soil in order to avoid breakages or damage.
At the start of each new passage, the machine travels for approx
a metre before the seeds reach the seed-planting furrow through
the delivery tubes. Vice versa, at the end of the passage, it
discharges all the seeds present in the delivery tubes. This should
always be borne in mind to obtain a good final result.
Always respect the following rules for successful sowing:
- Keep the tractor hydraulic lifting unit in its lowest position.
- every now and then check that the coulters are not blocked with
residues or clogged with soil that retains the seeds.
- check that the distributors are free from foreign bodies, that
may have accidentally entered the hopper. They could compro-
mise regular operation.
- The form dimensions and material of the drive shaft elastic
pins have been chosen for safety. The use of pins not original
or more resistant, could cause serious damage to the seeding
machine.
- Avoid curves with the machine grounded, neither work in
reverse.
Always lift it when changing direction or reversing.
- Start the power take-off progressively; sudden movements
are harmful to the belt.
- Maintain a seeding speed compatible with type and cultivation
of the soil in order to avoid breakages or damage.
- Lower the seed drill when the tractor is in forward gear, to
avoid clogging or damage to the planting coulters; for the
same reason the tractor should not reverse when the seed
drill is on the ground.
- Make sure that no foreign material (rope, sack paper) enters
the storage tank when seed is being loaded.
