PROBLEM TO BE SOLVED: To facilitate the travel of a mobile farming machine over a ridge. SOLUTION: A rice transplanter is linked to the rear part of the mobile farming machine so as to be freely lifted and lowered, and an arm 63 for going over the ridge is installed in the front part of the mobile farming machine. The arm 63 for going over the ridge is constituted so that the posture may be changed between a front protrusion state in which the arm 63 is turned in the front lower direction, and a rear housed state in which the arm 63 is turned in the upper direction or the rear upper direction. The second lifting and lowering lever 64 for lifting and lowering the transplanter is attached to the arm 63 for going over the ridge. When the mobile farming machine travels over the ridge while progressively traveling at a low speed, the rice transplanter at the rear part of the car body can be lifted and lowered by operating the second lifting and lowering lever 64 while preventing the floating up of the front part of the car body by pushing down the arm 63 for going over the ridge. As a result, when forgetting the lifting of the rice transplanter, the rice transplanter can be lifted while positioning at the operating position of the arm 63 for going over the ridge. The travel over the ridge can be easily carried out while preventing the floating up of the front part of the car body by regulating the front and rear balance of the car body.
