Abstract
To mow even soft grass more tidily in shearing mode without kicking pebbles, a pair of two grass cutting wheels are pivotally driven by an engine in two mutually-different directions. One cutting wheel is slidably fixed relative to the other cutting wheel for safety. The mowing machine can be used in common to shear off grass on the ground and trim a garden tree by adjusting an angle between a hollow grip pipe and the machine cutting surface.
