There is a walking-type mower that cuts grass while walking with a handle provided at the tip of the handle rod. There is a walking type mowing machine in which one side of a cutting blade provided on the left and right is inclined along an inclined surface so that two surfaces, a horizontal surface and an inclined surface, can be cut at the same time so as to be particularly convenient for cutting a ridge.

らず、作業が困難であった。The ridgeway is narrow, and when the direction is changed by the mowing machine, the mowing machine is driven on an inclined surface, or an operator walks on the inclined surface and turns forward to move forward. I had to do the tedious work of switching back and forth with the aircraft frame. Also, when mowing grass on the slope of the ridge, the worker moves the mowing machine up and down along the slope of the ridge while walking on the ridge, but when cutting the lower part of the slope, the worker sits down. The work was difficult because the body of the mower had to be moved to the lower part and the worker had to walk down the slope.

The walking mower is configured such that the rod 34 is pivotally supported, and the handle rod 34 can be fixed at an appropriate angle obliquely rearward and upward and at an angle substantially perpendicular to the machine frame. In addition, the walking type mower can handle the handlebar 34.
A loop-shaped handle 36 is provided at the tip of the handle so as to be appropriately fixable between a state perpendicular to the handlebar 34 and an extended state, and an accelerator lever 37 curved along the handle 36 is provided.

When turning the aircraft back and forth in a narrow road such as a ridge, the operator fixes the handlebar 34 almost vertically at the same position without moving, and holds the handlebar 34 or the machine frame. May be changed. Thus, the handle rod 34
Can be fixed substantially vertically with respect to the machine frame, so that the operator can easily change the longitudinal direction of the machine on narrow ridges without moving. Also,
In this walk-type mower, a loop-shaped handle 36 is provided at the tip of the handle rod 34 so as to be appropriately fixable between a state perpendicular to the handle rod 34 and an extended state, and is curved along the handle 36. When the accelerator lever 37 is provided, in normal mowing work, the handle 36 is fixed in a state perpendicular to the handle rod 34, and the operator can easily control the machine by holding the substantially vertical portion of the handle 36 with both hands. In the case of cutting work away from the operator, the handle 36 is fixed in a state of being extended with respect to the handle rod 34, and the operator holds the substantially horizontal rear end portion of the handle 36 with both hands to hold the machine. By controlling, you can work easily without taking an unreasonable posture. At this time, while holding the accelerator lever 37 provided along the handle 36, the cutting blade 3,
4 can also be controlled.
