Claims

[Scope of utility model registration request]

A machine body 3 with a seedling planting device 6 connected thereto and a control handle 4 extended to the rear is provided with wheels 1 that can be driven up and down via a hydraulic actuator 2, and the machine body 3 is provided with wheels 1 that can be moved up and down by a hydraulic actuator 2. At the same time, a device 12 for detecting the
The control valve (1) for the hydraulic actuator 2 is linked with the detection device 12, and the control valve is configured to maintain the level of the planting mud surface of the body 3 within a set range based on the detection level by the detection device 12. A lift control mechanism 15 is provided for automatically switching the Nir valve V, and the control valve (1) is set to a first position that allows the operation of the lift control mechanism 15, and has priority over the lift control mechanism 15. An operating lever 19 is linked to a second position in which the body 3 is forcibly raised by lowering the wheels 1, and can be freely switched between the neutral position, and a biasing mechanism is attached to the operating lever 19 to operate the operating lever 19. A walk-behind rice transplanter configured to keep the operating lever 19 biased in each of the first and second positions by reversing the biasing direction midway, wherein a guide member 22 of the operating lever 19 includes: an operation route R1 that linearly connects the first position and the second position;
deviating from the operation route R1, providing a preliminary raising operation route R2 having a starting point at the neutral position and ending at a preliminary raising operation position closer to the neutral position than the second position;
The biasing mechanism is attached to the operation lever 19 in a state where the biasing direction is reversed between the preliminary raising operation position and the second position, and the biasing mechanism is attached to the neutral position. A walk-behind rice transplanter characterized in that a holding mechanism 25 is attached for abutting and preventing displacement of the lever 19 toward the operating path R0 due to force.
