초록 ▼

A multi-bladed mulching mower is convertible between a mulching mode in which the grass clippings are deposited as mulch or a discharge/collection mode in which the grass clippings are discharged from the housing or are bagged. The mower includes two separate cutting chambers which are staggered forwardly relative to one another but otherwise are arranged side-by-side next to one another. The peripheral wall of the forward cutting chamber has a selectively openable gate which is closed in the mulching mode but is opened in the discharge/collection mode. The rearward cutting chamber is provided with a discharge outlet which can be selectively opened in the discharge/collection mode but is otherwise closed. When the gate and discharge outlet are opened and the mower is operating in the discharge/collection mode, the grass clippings in the forward cutting chamber are deposited onto the ground in advance of the rearward cutting chamber to be picked up and evacuated by the blade in the rearward cutting chamber as the rearward cutting chamber passes over the clippings during forward movement of the mower.
