PROBLEM TO BE SOLVED: To provide an agricultural work machine capable of preventing an extendable ground-leveling body from returning to a folded non-working state at the time of work.SOLUTION: An agricultural work machine 11 comprises a tilling body 18 for performing tilling work and a ground-leveling body 23 for performing ground-leveling work at the rear of the tilling body 18. In the ground-leveling body 23, an extendable ground-leveling body 31 is provided rotatably around a rotation fulcrum. A tension spring 32 for biasing the extendable ground-leveling body 31 so as to be in an extended working state and a folded non-working state is attached. A ground-leveling side attachment part of the tension spring 32 is positioned on the outer side than the rotation fulcrum during the extended working state of the extendable ground-leveling body 31, and positioned on the inner side than the rotation fulcrum during the folded non-working state of the ground-leveling body 31. |
