To provide a handle device used in a single-axis walking-type farm machine, which is capable of almost steplessly adjusting a handle mounting angle to a body roughly, which has a simple structure and the minimum number of parts to be changed and which is capable of being easily attached to the machine in which the handle device has not been attached, while accommodating the need for changing the mounting angle significantly temporarily even during farming, if any.

An engagement pin 5 supported against a supporting cylinder 4a rotating together with a pivoting shaft 3 is inserted and removed into/from a turning angle regulating part 2c provided at the prescribed distance from a pivoting part 3 of the handle 1 to permit the angle to the body of the handle 1 to be changed significantly. Inner clip washers 1a, 3a are provided between a mounting base of the handle 1 and the pivoting shaft 3 to permit both of them to be relatively turned, thereby almost steplessly adjusting the handle 1 vertically.
