If the machine is equipped with seed dressing, the new calibration must be carried out
approximately one are after sowing. Coating can reduce the feeding amount by up to 20%!
NOTE:
Handwheel must not be forced to zero-position. Simultaneous input shaft
rotating eases the adjustment. The use of sowing table and instructions for performing the
calibration test are discussed below.
NOTE:
Maximum speed in sowing peas and beans is 6 – 7 km/h
Turning the transmission cassette
FIG. 11. Transmission cartridge. I = Grain, II = Small seed
When the bigger sprocket of the cartridge is up, it is in a grain position. When the smaller sprocket
is up, it is in a small seed position. Position has been marked on the cartridge shell on the visible
side. In Fig. 11 a grain position is shown. Turning is done as follows: Remove the ring pins and
pull the cartridge out of its shafts. Turn the cartridge upside down. A sticker in the cartridge tells
the setting.
Bottom flaps
Feeding accuracy depends on the distance between the bottom flap and feeding roller, for this
reason it is important to have the bottom flaps in a right position, and that they will not be re-
adjusted after the calibration test without repeating the test. The bottom flaps are flexible, in case
some hard foreign item gets between the bottom flap and feeder roller.
Below are indicative values for most seeds. If you are sowing varieties other than those
recommended, compare the seeds based on their size and characteristics to the ones mentioned
below and carry out the calibration test according to respective adjustments.
