To avoid such a state as to move backward while a part of working apparatus is grounded on the earth as it is in an agricultural working machine equipped with the working apparatus at the rear part of a machine body.

A guide route of a gear shift operation tool 41 for operating a gear shift apparatus for traveling is constituted of a forward moving range 42, a backward moving range 43 and a neutral range 44 for connecting the forward moving range 42 to the backward moving range 43. When the gear shift operation tool 41 is operated from the neutral range 44 to an end part 44b of the backward moving range side of the neutral range 44, the operation apparatus at the rear part of the machine body is automatically raised and driven.
