发明名称 Mower cutting chamber with adjustable discharge geometry
摘要 A mower deck includes at least one cutting chamber with a spindle-mounted rotary cutting blade. The cutting chamber includes an upper wall and a sidewall. The sidewall presents a discharge opening. A cut-off baffle extends between the spindle and the sidewall discharge opening. The cut-off baffle adjusts between an open position in which the discharge opening is at least partially unobstructed and a closed position in which more of the discharge opening is obstructed. A spreader plate lies over the upper corner of the cutting chamber near the discharge opening opposite the cut-off baffle. The spreader plate adjusts between a first retracted position spaced away from the discharge opening and a second extended position closer to the discharge opening. The cut-off baffle and the spreader plate may be adjusted to control the discharge of grass clippings from the cutting chamber.

主权项 1. A mower deck for a turf mower, comprising: (a) at least one cutting chamber with a cutting blade spindle and a rotary cutting blade mounted to the cutting blade spindle, the cutting chamber having an upper wall and an outer extent bounded at least partially by a sidewall, the sidewall presenting a discharge opening defined by a first edge, an opposite second edge and the upper wall, the sidewall adjacent the second edge and the upper wall defining a cutting chamber upper corner, (b) a cut-off baffle rotatably mounted at the cutting blade spindle and including a baffle flange that extends toward the discharge opening, the cut-off baffle being able to be adjusted such that the cut-off baffle may be secured between an open position wherein at least most of the discharge opening is not obstructed by the cut-off baffle and a closed position in which more of the discharge opening is obstructed by the cut-off baffle, and, (c) a spreader plate lying over a portion of the cutting chamber upper corner, the spreader plate being triangular in shape and having an apex, a base edge and two side edges which extend away from the base edge and meet at the apex, the spreader plate being disposed in the cutting chamber upper corner such that the apex is adjacent to the cutting chamber upper corner and is farther from the discharge opening than the base edge and such that one of the side edges lies against the upper wall and the other of the side edges lies against the sidewall, the position of the spreader plate being adjustable between a first retracted position in which the spreader plate is spaced away from the discharge opening and a second extended position in which the spreader plate is closer to the discharge opening than when the spreader plate is in the retracted position.
