摘要： A mower unit (B) having a housing (13), blades (12) supported in the housing to be rotatable about vertical axes (P1) acting as the centers of rotation, cutting edges (12A) defined at front edge regions of each blade with respect to a direction of rotation thereof, and lift vanes (12B) erected from rear edge regions of each blade with respect to the direction of rotation thereof. Each of the lift vanes includes a first vane portion (12b) extending the more rearwardly, with respect to the direction of rotation, the farther away the first vane is from the center of rotation, and a second vane portion (12c) bent in the direction of rotation from a radially outward end of the first vane portion.

摘要： A mower unit of grass cutting machine has at least two blades. The left blade is rotatable clockwise, while the right blade is rotatable counterclockwise. A grass discharge passage is formed between the two blades. An endless rotational belt for transmitting drive to the two blades is offset forwardly in a region between the blades, thereby forming, between the blades, a space without the endless rotational belt. The grass discharge passage has an upper surface inclined rearwardly and upwardly to extend from a position forwardly of a pair of pulleys corresponding to the two blades.
