Abstract: A mulching mower mechanism, having an inverted U-shaped channel member positioned within the outer periphery of a cutting chamber of a mower deck for generally confining the clippings circulating at the outer periphery of the cutting chamber. The channel member extends generally across the mower deck's discharge outlet for generally diverting the stream of clippings away from the outlet and thereby serves to maintain the clippings within the deck to be re-cut by the blade. The channel member includes an upper and outer wall portions positioned adjacent the discharge outlet for generally blocking the clippings and air within the channel from exiting the discharge outlet. The channel member also includes an inner wall portion which separates the stream of clippings from the relatively clean air circulating within the inner portion of the deck.

Abstract: A mower cutting unit is provided with a rear-mounted grass catcher. The cutting unit includes front and rear rollers and mounted between the rear roller and the grass catcher is a rotary brush. The brush is mounted for adjustment into and away from engagement with the rear roller and for adjustment into and away from engagement with the turf. The brush may be driven either in the same direction as or counter to the direction of rotation of the rear roller during forward mowing operation. When driven counter to the direction as the rear roller, the brush may either be positioned for only cleaning clippings from the rear roller and depositing them into the grass catcher or be positioned for additionally sweeping the turf.
