<p>PURPOSE:To enhance the farm work efficiency as well as to ensure a simple operation even for the new women folks by setting up the decision standard line and at the same time steering right and left the steering wheel of the car based on the decision output of the sensor. CONSTITUTION:Three sensors 4A, 4B and 4C (right end) plus 5A, 5B and 5C (left end), which detect border 2b between farmed area 2c and unfarmed area 2b, are provided at the front part of car body 1 and arranged laterally at the right and left end parts of body 1. When body 1 runs in its most ideal condition, the right end part of rotary 3 crosses slightly on the line of border 2b. As a result, area 2a can be farmed to the full. In response to this, central sensor 4B among the sensors at the right side detects the range of a fixed area on 2b. At the same time, sensor 4A closest to body 1 and sensor 4C most distant from body 1 detect areas 2a and 2c respectively.</p> |
