PURPOSE: To provide the title system designed to quickly, easily regulate the height of a rear cover by pivoting a rotary machine frame with an arm to be revolved with an operating lever, connecting the arm to a reinforcing board for an upper cover and providing a means to hold the lever at the revolving position.
CONSTITUTION: A rear cover 4 covering the rear of a tilling part 2 is pivoted on the rear end of the upper cover 3 covering the upper portion of the tilling part 2, and the upper cover 3 is movably supported back and forth in the circumferential direction of the tilling part 2 relative to a rotary machine frame 5. In the title system having such a constitution, the rotary machine frame 5 is pivoted with an arm 7 to be revolved with an operating lever 6, this arm 7 is connected, through a link 9, to the reinforcing board 8 on the upper portion of the rear of the upper cover 3, and a means 10 to hold the operating lever 6 at the revolving position is located in between the rotary machine frame 5 and the lever 6; thereby, the upper cover 3 can be moved back and forth via a link mechanism by simply revolving operation of the lever 6 and the rear cover 4 can be regulated in height quickly and easily, thus improving the operating efficiency for the regulation.
