    摘要： An adjustable gauge wheel support structure is provided for selectively adjusting the height of cut of a mower deck. The structure includes a gauge wheel carried on a U-shaped arm which is pivotally attached to a deck bracket. A spring loaded J-pin locking mechanism is provided to secure the arm in a plurality of positions relative to the bracket. The wheel is supported on one of the parallel legs of the U-shaped arm and twisting forces encountered by the wheel and its supporting leg are resisted through locking the two legs and bracket together with the J-pin. No tools are required to adjust the wheel height and no parts have to be removed or loosened to make the adjustments, thereby minimizing the likelihood that parts will be lost or misplaced.

    摘要： A composite insert is provided for converting a rotary mower deck from side discharge to mulching usage. The insert can be detatchably mounted in the mower deck and provides a cutting chamber wherein grass can be cut, mulched and redistributed onto the ground beneath the mower deck. The insert forms with the mower housing a cutting chamber which includes a reduced cross-sectional area at the front portion that provides for confining and accelerating the movement of air and clippings there through to minimize build-up of clippings adjacent the chamber surfaces. At the rear portions of the chamber, a larger cross-sectional area is provided to permit the clippings to slow down and disperse, allowing the clippings to be distributed and/or redirected into the blade for mulching. It is preferred that the insert is adapted for use with a two-bladed mower deck.
