IPC: A01D45/16
Filed: 1983-07-07
Abstract: PURPOSE:To make easy the starting and stopping operations of a tobacco leaf picking machine, by operating the tension pulley of a multi-speed transmission through either an operating lever that can be operated while one is seated on a seat or a pedal that can be operated while one stands on the platform. CONSTITUTION:When a swingable lever 8 is pushed down by the foot of an operator seated on a seat 7, an arm 6a is pulled and a tension pulley 6 is brought against the action of a spring in contact with a belt 7 to make it tight. Accordingly, the power of an engine E is transmitted to driving wheels 2 to move the machine body forward. When the foot is relased from the swingable lever 8, the lever 8 becomes upright and the arm 6a moves to the original position due to the action of the spring. Therefore, the power of the engine E is not transmitted to the wheels 2 and the machine body stops. Further when the operator stnads on the seating plate 11 of the machine body and steps on the pedal 12, the arm 6a is rotated, and the machine body moves forward as mentioned above. If the foot on the pedal 12 is released, the machine body stops as mentioned above.
