The quantity to be sown is adjusted by moving the feeding roller laterally in relation to the feeding
chamber. The adjustment is carried out with the hand wheel situated at the left drill end (picture 12).
The feeding system is manufactured of stainless materials.
The bottom valves under the feeding chambers are adjustable. The adjusting lever is situated at the
rear end of the machine (picture 10).

8.1 Regulating the feeding quantity
The quantity to be sown is adjusted with the hand wheel at the left machine end (picture 12). The
hand wheel is locked with a plastic piece which also contains the main scale 1-10. Every space
between two adjacent numbers corresponds to one complete turn of the hand wheel. The hand
wheel can be locked in 10 notches marked by numbers 0-9 and thus a total of 100 various setting is
available.
To adjust the feeding the plastic locking piece must be pressed toward the machine end in the
direction of the arrow and at the same time it must be turned 90 degrees upwards which unlocks the
hand wheel.
When rotating the hand wheel anticlockwise the feeding grows bigger. When you know the desired
quantity to be sown you get the estimate adjustment for the feeding from the sowing chart inside the
lid of the machine.
It is advisable to carry out the adjustment so that the desired adjustment is approached from the
higher settings. Should the original setting be lower than the desired on the hand wheel must be
turned anticlockwise ½-1 turns beyond the required setting. After that the wheel is turned clockwise
to the required setting. Then put the locking piece to a notch of the hand wheel and the wheel and
the locking piece get locked.
Do not forget that the setting given in the sowing chart is an estimate and that the actual feeding
quantity varies between different seed varieties.
We recommend that you check the feeding quantity by means of a calibration test.
The normal setting of the bottom valves is notch 2. If dirt gets into the feeder the feeding rollers can
get blocked. This can affect the feeding quantity in a considerable degree. We recommend that you
