Rotating the power transmission cassette between positions I and II
See Figs. 22 and 23. Remove the ring pins and pull the cassette from its shaft. Rotate the cassette
so that it is in a backward position to the same cassette sleeves, with a different side exposed.
Never turn the cassette upside down, i.e. so that the shaft and cassette sleeves switch places. The
selected setting (I or II) is marked on the visible side of the cassette cover. The position shown in
Fig. 23 allows very small seed amounts, i.e. rapeseed 5 kg/ha, to be sown.
Bottom flaps
Feed accuracy is dependent on the appropriate distance between the bottom flap and roller feeder.
It is important that the bottom flaps are in the correct position, and that they are not adjusted
following a calibration test without repeating the calibration test. Bottom flaps are flexible, in case
any external foreign object protrudes between the bottom flap and feed roller.
Figure 24. Bottom flap adjustment lever, seed.
Adjustment position 4 of the bottom flaps is used only when seeding especially large seeds (e.g. certain
canned peas). Note that in position 4 the feed amount increases when driving uphill.
Caution! The seed can flow out of the container freely when the bottom flap lever is
moved below past the scale.
10. Fertilizer feeding equipment and adjustments
Overview
On the machine, fertilizer feed chambers make up half the number of the seed feed chambers. Feed
amount adjustments are made by turning the feed rollers mounted on the fertilizer feed axis sideways in
relation to the feed chambers. Adjustments are made using a hand-wheel on the left side of the machine.
Electrical adjustment is also available as an option.
The feed chambers are located at the bottom of the containers. This solution provides an almost standard
seed amount despite any tilting of the seed drill from side to side, or the driving direction. The feed is a
groove-feed type, in which the feed bodies are called feed rollers, see Fig. 28. The feed rollers are equipped
with a helical thread and are made of plastic. The bottom flaps under the feed rollers are adjustable, by
means of an adjustment lever in the center of the front end of the machine, see Fig. 26. The entire fertilizer
feeding machine is manufactured of corrosion-resistant materials. The fertilizer container enables the
application of all types of granular fertilizer. The use of powdered fertilizers should be avoided. A mixing
shaft is available as an option.
