TECHNICAL CHARACTERISTICS
3.2 USE ACCORDING TO DESIGN
- Fertiliser spreaders D-903 & D-903 PLUS have been de-
signed for normal use in agricultural work, especially for
spreading with mineral products.
- If the machine is used in circumstances other than the above,
SOLÁ will not be held responsible for any damage caused.
- The user must observe all regulations concerning safety, traf-
c and hygiene.
- If the machine is modied by the user, the manufacturer’s
warranty is cancelled.
- SOLÁ will not be held responsible for any damage caused.
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 MA
CHINE 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 FA
MILIAR 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 SYS
TEM. THESE PARTS AGE NATURALLY AND THEIR LIFE
SHOULD NOT SURPASS 6 YEARS. PLEASE REPLACE
WHEN NECESSARY.
WHEN RAISING THE FERTILISER SPREADER, THE
FRONT AXLE IS UNLOADED. ENSURE THAT THE MA
CHINE HAS ENOUGH LOAD TO PREVENT IT OVER
TURNING. 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 PO
SITION TO PREVENT THE MACHINE FROM LOWERING
OR FALLING.
FILL THE FERTILISER SPREADER WHEN IT IS IN ON THE
GROUND, ENSURE THE TRACTOR ENGINE IS OFF AND
THE FERTILISER OUTLET OPENINGS ARE CLOSED.
ALWAYS CONNECT GENTLY THE PTO SHAFT’S CLUTCH
IN ORDER TO PROTECT THE FERTILISER SPREADER.
OTHERWISE THE MACHINE COULD BE SERIOUSLY
DAMAGED.
BE CAREFUL WHEN FILLING THE FERTILISER SPREAD
ER AND TAKING INTO A FIELD WHICH IS FAR AWAY. IT
IS POSSIBLE THAT THE FERTILISER COMPACTS AT THE
BOTTOM OF THE HOPPER AND THE OUTLET OPEN
INGS ARE OBSTRUCTED. IN THIS CASE IT WILL BE NEC
ESSARY TO COMPLETELY OPEN THE OUTLETS, LET THE
PTO SHAFT’S CLUTCH SLOWLY IN AND SPREAD SOME
FERTILISER. AFTER THIS OPERATION, PLACE THE AD
JUSTING LEVERS IN THE POSITION CORRESPONDING
TO THE CHOSEN FLOW AND SPREAD NORMALLY.
NEVER DELIBERATELY CAUSE THE EXIT OF THE FERTIL
ISER FROM THE UPPER PART OF THE HOPPER. THERE
IS A SERIOUS RISK OF OBSTRUCTING THE AGITATOR.
AFTER EACH WORKING DAY, THE SPREADING VANES
AND THEIR TIGHTING SCREWS SHOULD BE CHECKED.
THEY SHOULD BE REPLACED WHEN THEY ARE VISI
BLY WORN OUT, SINCE THE WEAR IS CAUSED BY THE
CONTACT WITH THE FERTILISER AND IT IS BECOMES
WORSE WHEN THE FERTILISER IS MORE ABRASIVE.
CONSEQUENCES OF WORN OUT SPREADING VANES
ARE A BAD IRREGULAR SPREADING AND, ESPECIALLY,
THE RISK CAUSED BY FRAGMENTS DETACHED FROM
THE SPREADING VANES.

ESSENTIAL SPREADING CONCEPTS
4. ESSENTIAL SPREADING CONCEPTS
4.1 FACTORS TO BE TAKEN INTO
ACCOUNT FOR A GOOD SPREADING
1- Fertiliser’s granulometry: Reject fertilisers with grains of ir-
regular 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 distribution.
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 spread-
ing of the fertiliser, and their wear can have great in uence
when spreading the fertiliser onto the ground. Keep them in
optimal condition.
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 spreading. To know this
distance, follow the adjusting instructions. To increase the pre-
cision, a test at the  eld could be performed by checking the
amount of spread fertiliser using boxes placed on the ground.
4.2 FERTILISER SPREADING
It is well known that the amount of fertiliser spread onto the eld
directly aects in the output of the harvest.
Nevertheless, what is even more important than the amount of fer-
tiliser is the uniformity in which it is distributed along the terrain.
Fertiliser spreaders D-903 and D-903 PLUS distribute the fertil-
iser as shown in the followingdiagram:
To get a uniform distribution, the fertiliser should be spread over-
lapping the tramlines so the  nal result is a  at diagram like the
one below:
Uniformity in fertiliser distribution is measured by means of the co-
eciency of variation (CV). The CV is calculated using a statistical for-
mula 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.

STARTING
5. STARTING
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 link-
age.
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.
Fig. 2
In working position, the fertiliser spreader should stay horizontally
and its disc shoud be at 75 cm from the ground (Fig. 3).
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.
Fig. 4
Once the fertiliser spreader is coupled with the tractor, THE PTO
SHAFT SHOULD BE ADAPTED:
1- 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.
2- Cut the spare plastic and metal into parts of the same length and
remount the PTO shaft.
3- Operate the hydraulic lift and check that the PTO shaft’s move-
ment is correct.
4- Secure the PTO shaft using the chain.
