Abstract

In previous report (Part I), two gantries were prototyped, and it became clear that the prototyped sprayer and strawberry picker on gantry are effective in saving labor for spraying and picking work. In this paper, to enhance general-purpose properties of gantry, the applicability of gantry to rotary tillage and ridging work, using a commercially available rotary tiller and ridger, was studied. The working performance test of the gantry showed that with a 7-kW motor for driving operation machine, a running speed of gantry for rotary tillage at less than 30cm/s and that for 25cm high ridging work at less than 14cm/s, the gantry works flawlessly. The soil pulverizing performance, theoretical field capacity, and ridge shaping accuracy of the gantry were equivalent to conventional operation. In addition, a prototype truck controlled by a programmable device for transferring the gantry to a neighboring ridge was developed, and its performance was confirmed.
