3.11.2 TRIAL SOWING GEARBOX TABLE
This Table (Tabe 2) indicates the number of turns that the seeder's
gearbox must make in order to perform a trial sowing when the
machine is stationary.
This turn value depends on the model of the seeder and its work
width.
In the case of working widths that differ from those indicated in
the table, it is possible to calculate the n° of gear revolutions.
For example: There is a working width of 2.20 m with standard
6.00-16 wheels.
For reference, use the values, n° of gearbox turns, of the nearest
working width which in this case is, according to the table, 2.50
m with values: n° of gear revolutions= 32.
N° of gear revolutions width of 2.20 m:
32 x 2,50= 36,3 gear revolutions;

USE AND MAINTENANCE
3.11.3 EASY METHOD FOR DETERMINING THE NUMBER OF
SOWING TEST
The number of gearbox turn given in the table to be performed for
the stationary sowing test have been calculated on the basis of
ideal conditions. In actual working situations other factors can
cause significant variations between the values given in the table
and actual sowing results. The most common of these are: loss
of drive wheel adherence caused by moisture and/or terrain
conditions, fertilizers or other products mixed in with the seed
that reduce its flow rate, variations in seed weight, etc.
To obtain the actual number of gear rotations (for 1/100 ha),
proceed as follows: for a seeder 3,00 m wide with 6.00-16 drive
wheels inflated to a pressure of 3 bar. When large quantities are
to be distributed per hectare (e.g. wheat, barley, peas, etc.) set
the planting unit as in table 3 and fill the hopper to half its normal
load. Cover a distance of 33,3 m, counting:
a) the number of rotations made by the drive wheel and multiply
by 1.818 (wheel/gear transmission ratio) to obtain the number of
gear rotations to perform for the stationary test. Ex.: 16 wheel
rotations counted x 1.818 = 29 gearbox turns.
b) counting directly the number of gearbox turns from the
protruding shaft-end into which the sowing test crank is inserted.
IMPORTANT: The length of the test run will vary depending on the
32
working width, such that the product of the width (in m) ´ test run
33
(in m) is always equal to a surface area of 100 m
31
hectare).
