in one are (compare part 13, Instruction to improve sowing accuracy). Instead the forward
movement affecting the accuracy of surface area measurement is defined by the forward
movement of supporting wheels. Determine with a tensile test how much the machine proceeds
in your sowing conditions, when the feeler wheel rotates one turn.
The calibrations of the machine are done in seed and fertilizer sides to the trays below feeder
chambers. Exercise caution when pushing the troughs into place. Hold them in an absolutely
straight line in terms of the machine. If a trough is pushed strongly so that its head is directed
upwards, the trough can hit one of the feeder chambers and damage them.
The air-pressure of feeler wheels (front wheels) is easy to check asunder every second wheel a
relatively sturdy support is placed, when lowering the machine which however is not too wide (for
example log etc.). This lifts up the whole coulter sledge with the tires, and a hand can fit the tire
vent.
NOTE: BE CAREFUL WHEN INSTALLING SUPPORT THAT IT IS WELL SET AND SECURE
UNDER THE TIRE. IF THE SUPPORT FALLS, HAND MAY BECOME JAMMED.
Your seed and fertilizer drill is equipped with an electronic monitoring device, with surface sensors
for seeds and fertilizer. Use caution when taking screens from the tanks. A screen hitting a sensor
can damage it.
Similarly, the installation of the seed dressing tanks and decoupling should be carried out with
caution.
DO NOT SOW IN CONDITIONS WHICH ARE TOO WET THE SOIL CONDENSES TOO MUCH,
AND THE AIRINESS / WATER PERMEABILITY DETERIORATES
WATCH THE SOWING DEPTH. E.G. IF THE FIELD HAS BEEN MODIFIED THE SEED MUST
BE LAID ON UNMODIFIED SOIL. WATCH OUT WHEN MODIFYING DURING SPRING TIME,
THAT MODIFICATIONS DO NOT GO IN TOO DEEP.
MOST COMMON ERROR IN THE USE OF NOVA COMBI IS THAT COULTERS TOO MUCH
WEIGHT IS PLACED ON COULTERSBECOME TOO MUCH WEIGHED ON. WEIGHING IS
SUFFICIENT WHEN THE WORKING DEPTH IS ACHIEVED, THAT IS THAT THE COULTER
SLEDGE MOVES ON STEADILY RELYING ON THE FRONT FEELER WHEEL, NOTHING
MORE! TOO MUCH WEIGHT ON THE COULTER INCREASES THE RISK OF MACHINE
BECOMING BLOCKED AND STRAINS THE MACHINE STRUCTURES UNNECESSARILY
If the machine is twisting to the left, reduce coulter weight and make sure that the machine
is at horizontal level. If the front end of the machine is lower than back, lengthen the
drawbar rigging screw.
