PROBLEM TO BE SOLVED: To solve the problems wherein a rotation case, a planting claw part and a connecting member are provided to increase in number of parts, resulting in increasing the weight to increase the cost.SOLUTION: In a rice transplanter 1, a plurality of planting transmission cases 46 are projected backward in parallel from a planting frame 49, a longitudinally midway part of a rotation case 44 is rotatably supported on both right and left side surfaces of the rear part of the planting transmission case 46, and a planting claw part 45 is rockably disposed in both end parts in the longitudinal direction of the rotation case 44. The planting claw part 45 includes: a claw body 71 for cutting off a seedling; a push rod 72 for pushing out the seedling cut off in the vicinity of a field surface; a planting claw shaft 64 projected from the rotation case 44; a cam 75 fixed to the planting claw shaft 64; a push arm 76 rocked in contact with the cam 75; a spring 73 energizing the push rod 72 in the projecting direction; and a claw case 45a to which the above members are fitted, wherein the claw case 45a is constructed to be bilaterally symmetrical. |
