3. MACHINE APPLICATION
TUME Draco seed and fertilizer drill is suitable for seeding the seeds of the most common cereal, oil
and grass plants, as well as for peas and beans. Grainy fertilizer can be sown at the same time. The
fertilizer is mulched into the soil evenly using the front cultivator. If required, the machine can be
used separately only for fertilizing or only for seeding.
The required seed and fertilizer can be transported to the fields which are a short distance away
inside the machine's containers, if the roads are in good condition. In this case the maximum speed
allowed is
15 km/h
. On uneven roads and long distances the transfers must be made with an empty
machine. The machine must not be used for other than transferring immediately needed seed and
fertilizer, and extra loads, objects, animals or passengers are not allowed to be carried in the con-
tainers or on the machine.
General about the use of the machine
There are two working widths of Tume Draco, 3 meters and 4 meters. The structure in the machines
is otherwise the same, but the 4 meter machine can be changed to 3 meters for transportation. This
happens by folding the front cultivator up, after which ½ meter sections are turned from the harrows
(both from right and left) to the front of the container, pictures 1, 2 and 3. The rear harrow also turns.
The folding function is explained in sections 11.2 and 11.3, EPEC seeding electronics. The 3 meter
model is fixed and it is not changed for transportation in any way. In this model the cultivator is made
of one part which moves in an up/down direction, same as the coulters and the rear harrow.
The fertilizer feeding device is designed only for feeding grainy fertilizers. There are usually
difficulties when feeding powdery fertilizers. At worst powdery fertilizers may cause feeding
equipment to cut and get stuck, which is why it is advisable to use only grainy fertilizers.
Fertilizer mixes evenly into the whole cultivation layer because of the cultivator in front of the
machine.
The seed coulters are equipped with two discs. The coulters penetrate well even in conditions which
include plenty of plant waste. The working depth is adjusted accurately with a roller wheel for each
coulter. The working depth adjustment is centralized so every coulter does not need adjusting
separately. The machine also has an automatic adjusting system, Autolevel, which keeps the
required seeding depth always correct. See section 11.6
The adjustment area of the coulter pressing is enough for all types of soil. The adjusting is performed
hydraulically from the tractor. The coulter weight is 0 – 100 kg per coulter, and it is automatically
adjusted (see section 11.6).
The supporting wheels under the Draco's container level the fertilizer and pre-condense the soil for
the seeding coulters following behind. Pre-condensing ensure waters capillary rising so the seed can
reach it. The levelling / working depth adjusting wheel behind the coulter finishes the levelling.
The rear harrow spreads the soil between the coulters so the surface stays suitably grainy and does
not become muddy.
The machine has remote fertilizer adjusting device as standard. There are 3 memory spots which
can be electronically adjusted or changed even during the drive. There are no memory spots for
seeds, but even the seeding value can be adjusted from the drive computer.
More information on equipment can be found in section 13.
