Studies on the Bean Cutter

Abstract

We manufactured and tested Bean Cutter (fig1) and the results of the field tests are as follows:
(1) This bean cutter operates well on the speed from 2.5 to 3.0m/sec. If cutting speed is too fast (over 5.0m/sec), row operation of tractor may be difficult. In the field speed outlet cutting beans varies 1.0/1.3 hectares per hour.
(2) Whether cutting beans is well down or not, depending upon the time for harvesting. If it is too late, bean cutter could not cut the beans, but pull up them.
(3) Harvesting loss is due to shatteing. In the testing result, shatting induced by the cutting operation should not occur, when the moisture content of pads is over 20%. Therefore, harvesting by this cutter may be down at the suitable time, before the moisture content of pads becomes below 20%, as early morning.
