FARM WORK MACHINE AND METHOD FOR MAINTENANCE WORK FOR ROTARY

摘要

PROBLEM TO BE SOLVED: To provide a farm work machine of which maintenance works can be efficiently carried out. SOLUTION: This farm work machine 1 is equipped with a rotary 16 that plows and crushes the soil, a soil grader 30 that grades the crushed and plowed soil and a setting unit 31 that sets the soil grader 30. The setting unit 31 can be set to the soil-grading state at which the soil is graded by means of the grader 30 and to the soil-mulching state at which the soil is collected for mulching. The setting unit 31 can set the soil grader to the maintenance work state at which the grader 30 is almost all exposed toward the rear direction. The soil grader 30 is positioned higher than the rotary shaft of the rotary 16 in the maintenance work state.
