Claims

[Scope of utility model registration request]

A traveling transmission lever 9 and a rotary transmission lever 10 are arranged rearward from the traveling transmission case 2 and the rotary case 8 of the tilling device 7 connected thereto.
, and when the traveling shift lever 9 is in the reverse operation position, the shift operation of the rotary shift lever 10 is checked, and when the rotary shift lever 10 is in the shift operation position, the traveling shift is controlled. In the backward movement control device for a walk-behind cultivator, which is provided with a mutual check device 11 for checking the reverse operation of the lever 9, the mutual check device 11 is comprised of shift operation positions H and L at both left and right ends, and a neutral operation position at the center. Rotary shift lever 10 operated along a T-shaped guide groove 13 of a shift guide plate 12 with position N
A check pin 15 is provided on the top surface of the shift guide plate 12, which protrudes from the top surface of the shift guide plate 12 when the rotary shift lever 10 is operated from below to above at the neutral operating position N. A slide check plate 16 is provided which allows the check pin 15 to protrude when the lever 9 is in the forward operation position, and which abuts and prevents the check pin 15 from protruding when the travel shift lever 9 is in the reverse operation position. A backward movement restraining device for a walk-behind cultivator, which is constructed by providing a mutual restraining device 11 and biasing the restraining pin 15 of the mutual restraining device 11 toward the rotary speed change lever 10 side.
