摘要： A mower with a grass catcher (10) for collecting grass clippings transmitted from a mower unit. The grass catcher has an inlet opening (12) in a front position thereof, and an outlet opening (13) and an openable lid (14) in a rear position. The grass catcher (10) is connected to the rear end of a vehicle body to be supported in a suspended state by a grass catcher support unit (100). The support unit includes mounting posts (9) attached to the rear end of the vehicle body and extending upward, and a support link mechanism (20) for interconnecting upper regions of the mounting posts and lower rearward regions of the grass catcher, and for switching the grass catcher between a grass clippings collecting posture with the inlet opening directed forwardly of the vehicle body, and a raised dumping posture with the outlet opening directed downward. The support link mechanism performs a switching process for switching the grass catcher from the grass clippings collecting posture to the raised dumping posture. The switching process includes a translating process for translating the grass catcher obliquely rearward and upward while maintaining the grass catcher substantially parallel to the grass clippings collecting posture, and a rotating process for rotating the grass catcher until the outlet opening is directed downward.
