Abstract
The authors trially made the horizontal seed-plate feed type device adaptable for sawing of several crops and experimented its running performance at various revolving speed. Results obtained may be summarized as follows.
1. The device trially made discharges seeds of barley and wheat almost three times as accurately as the horizontal-rotor feed type, which is common at present in Japan.
2. In proportion as the running speed of cells in creases, the variation of numbers of discharged seeds per a unit distance reduces gradually in barley and wheat, and the variation of discharge distances increases a little in rape. In case of corn and soybean, the variation of discharge distances is minimized when cells run at about 0.04m/sec.
3. The cells of this device are ought to be run at the adequate speed shown below:
barley and wheat over 0.09m/sec
rape under 0.07m/sec
corn and soybean about 0.04m/sec
