SAFETY INSTRUCTIONS
3.3 GENERAL SAFETY INSTRUCTIONS
- Before starting the machine, please check the machine is in good condition
for work and is safe for road use.
- Check that visibility is clear around the machine and there is no person in
the working area.
- In thoroughfare, please observe traffic signs and regulations.
- It is forbidden to ride on the machine or climb into the machine when it
is running.
- Before using the machine, the user must be familiar with all operating
elements.
- Please be extremely careful when coupling and uncoupling the machine
to the tractor.
- Please check that the PTO shaft is in good condition and well protected.
Prevent the protective tube from turning by holding both the tube and
chain provided for this purpose.
- Mount the PTO shaft’s transmission only when the tractor’s engine is off.
- Before connecting the PTO shaft, be sure that the danger zone surrounding
the machine is clear.
- Never leave the tractor’s driver’s seat while the machine is in operation.
- Do not deposit external elements inside the hopper.
-When mantaining the hydraulic system of the fertiliser spreader, make sure
that it is depressurised and the tractor’s engine is off.
- Please regularly check the condition of the tubes and hosepipes in the
hydraulic system. These parts age naturally and their life should not surpass
6 YEARS. Please replace when necessary.

12
SAFETY INSTRUCTIONS
- When raising the fertiliser spreader, the front axle is unloaded. Ensure that
the machine has enough load to prevent it overturning. At this time you must
ensure that the condition of both the steering and the brakes is optimal.
- During transit with the raised fertiliser spreader, block the lowering switch.
Before leaving the tractor, lower the fertiliser spreader onto the ground and
remove the tractor’s starting key.
- Always use enough supporting elements when maintaining the machine
in a raised position to prevent the machine from lowering or falling.

13
ESSENTIAL SPREADING
CONCEPTS
4.1 FACTORS TO BE TAKEN INTO ACCOUNT FOR A GOOD
SPREADING.
1- Fertiliser’s granulometry
Reject fertilisers with grains of irregular size or with grains that break easily.
This makes uniform spreading dicult.
2- PTO shaft speed
PTO shaft’s speed determines the turning speed of the spreading discs and,
consequently, the working width. Speed should be 540 rpm.
3- Forward speed:
Variations in forward speed modify the amount of fertiliser spread onto the
ground.
4- Hopper’s position:
The hopper should stay horizontal since lateral or longitudinal lean modify
the fertiliser’s distribution onto the ground.
5- Working height:
The working height should stay constant at 75 cm mesured from the disc
to the ground. This height should be checked at the eld. It should not be
checked when coupling the machine in the warehouse.
6- Do not fertilise if the weather is windy:
Wind modies the spreading direction of the fertiliser grains as well as dis-
tribution. The wider the working width, the lower the dose and the more
irregular the grain size, result in highly uneven spreading in windy conditions.
7- Wear and tear of the spreading discs and spreading vanes:
Spreading discs and spreading vanes are essential in the spreading of the
fertiliser, and their wear can have great inuence when spreading the fertiliser
onto the ground. Keep them in optimal condition.
4. ESSENTIAL SPREADING CONCEPTS

14
ESSENTIAL SPREADING
CONCEPTS
8- Check fertiliser’s ow:
Perform a previous calibration test in the warehouse in order to know exactly
the amount of fertiliser going to be spread. Dosage is going to be very di-
erent when using dierent kinds of fertiliser, as it depends on factors such
as density, moisture content, etc...
9- Distance between tramlines:
Keeping the distance between tramlines is essential to get optimal sprea-
ding.To know this distance, follow the adjusting instructions.To increase the
precision, a test at the eld could be performed by checking the amount of
spread fertiliser using boxes placed on the ground.

15
ESSENTIAL SPREADING
CONCEPTS
4.2 FERTILISER SPREADING
It is well known that the amount of fertiliser spread onto the field directly
affects in the output of the harvest.
Nevertheless, what is even more important than the amount of fertiliser is
the uniformity in which it is distributed along the terrain. Fertiliser spreaders
D-903 and D-903 PLUS distribute the fertiliser as shown in the following
diagram:
To get a uniform distribution, the fertiliser should be spread overlapping
the tramlines so the nal result is a at diagram like the one below:
Uniformity in fertiliser distribution is measured by means of the coe-
ciency of variation (CV). The CV is calculated using a statistical formula
based on the data obtained from the overlapping technique.
Fertiliser’s manufacturers agree on the fact that CV is very good if it stays
below 10%, it is medium if it stays between 10% and 15%, and it is bad
if it exceeds 15%. The last case should be avoided.

5.1 COUPLING TO THE TRACTOR
The fertiliser spreaders D-903 and D-903 PLUS are provided with bolts of
category II for their coupling to the tractor’s three-point linkage.
To the make the coupling easier, the fertiliser spreader is equipped with two
supports which, when lowered to a vertical position (Fig. 2), increase the
height of the coupling point.

STARTING
EIn working position, the fertiliser spreader should stay horizontally and its
disc shoud be at 75 cm from the ground (Fig. 3).
5.2 PTO SHAFT
PTO shaft’s turning speed should be 540 rpm and it is important to keep this
constant while working.

19
STARTING
Once the fertiliser spreader is coupled with the tractor, THE PTO SHAFT
SHOULD BE ADAPTED:
Dismount and insert one end into the tractor’s universal joint shaft and the
other end into the fertiliser spreader.
Look for the minimal movement length “L” (Fig. 5) by raising and lowering
the hydraulic lift.
Cut the spare plastic and metal into parts of the same length and remount
the PTO shaft.
Operate the hydraulic lift and check that the PTO shaft’s movement is correct.
Secure the PTO shaft using the chain.
WHEN OPERATING THE PTO
SHAFT CHECK THAT THE ENGINE
IS OFF. ALWAYS WORK WITH THE
PTO SHAFT PROTECTED AND
IN GOOD CONDITION. PREVENT
THE PTO SHAFT’S TUBE FROM
TURNING BY SECURING IT WITH
THE CHAIN PROVIDED.
WHEN LOWERING THE FERTILISER SPREADER TO THE GROUND, UNPLUG
THE TRACTOR’S UNIVERSAL JOINT SHAFT SO THAT THE PTO SHAFT DOES
NOT HAVE AN EXCESSIVE INCLINATION MAX. 35º.
When holding the tractor universal joint shaft’s clutch in, perform it gently.

5.3 COUPLING THE TRAILED FERTILISER SPREADER TO THE
TRACTOR
Fertiliser spreaders D-903 and D-903 PLUS Trailed are equipped with
a type of coupling (axle-swivelling ring) which can be easily adjusted to
different heights.
Once coupled to the tractor, the fertiliser spreader should stay horizontal.
To make it easier, the height of the coupling ring can be adjusted in two
different positions.
To switch between heights, simply invert the ring’s position. In some cases
it is possible that none of the two positions is the correct one to level the
fertiliser spreader horizontally. If this is the case, the platina which holds the
ring in the right position should be soldered and correctly secured.
