20120067019 | MECHANISM FOR CONTROLLING POSITION OF DISCHARGE BLOCKING FLAP FOR ROTARY MOWING DECK - A push and release operator control for selectively opening or closing the discharge blocking flap of a lawnmower. The first portion of travel of the actuator raises the discharge blocking flap toward its balance point. As the blocking flap reaches the balance point the actuator is released which allows the blocking flaps momentum to carry it through the balance point where gravity takes over to finish the travel. The actuator is reset by the blocking flaps motion after passing the balance point. Once the actuator is reset by the blocking flaps travel the same push and release of the actuator will return the blocking flap to it original starting position. | 03-22-2012 |

A handle can be positioned adjacent to an upper surface of the mower deck of the lawnmower and coupled to the shutter door, wherein the handle is pivotably movable with respect to the upper surface to cause movement of the shutter door. A locking member can be positioned between the handle and the upper surface, the locking member being movable with respect to the handle and operable to retain the handle in one of a plurality of predetermined positions corresponding to the closed positions and open position of the shutter door. | 04-25-2013 |
20130139485 | DUAL BLADED WALK POWER MOWER WITH REAR BAGGING MODE - A walk power mower has a mower deck that encloses a pair of rotary cutting blades with the grass clippings from the blades being discharged through a rearwardly extending grass discharge tunnel in a rear bagging mode of operation. The blades are powered by a timed drive system that is carried by a horizontal apron that is part of a cast aluminum engine mount. The engine mount and the apron are bolted to a stamped steel deck shell that forms the cutting chamber in which the blades rotate. The mower has a side discharge mode in which a side discharge chute is releasably mounted over a side discharge opening. The chute carries a flow cutoff baffle having an inwardly protruding inner end that sticks through the side discharge opening to intercept and direct the clippings out through the side discharge opening and through the chute in the side discharge mode. | 06-06-2013 |
20140157747 | MOWER AND GRASS MOWING MACHINE INCLUDING THE SAME - There is provided a mower in which a guide member does not easily protrude on the side of the mower, and a grass mowing machine including the same. A mower for discharging mowed grasses from a discharge port provided in a side part of a mower deck to an exterior of the mower deck includes a flexible rubber sheet formed in a flat plate shape, a pivot frame, support frames, and a pivot shaft for attaching the rubber sheet to the mower deck oscillatably in the up and down direction, and fixing clips for fixing the rubber sheet to the mower deck in a state that the rubber sheet is bent into a shape capable of guiding the mowed grasses discharged from the discharge port. | 06-12-2014 |
20140318099 | MULTI-BLADE MOWER DECK WITH MULCH/SIDE DISCHARGE CONVERSION - A multi-blade mower deck with mulch/side discharge conversion includes a mulch gate mounted under the mower deck and connected to a vertical hinge under the mower deck. The mulch gate extends to the right and rearwardly around a portion of a perimeter of the right cutting chamber. A mulch gate lever on top of the mower deck is connected to the vertical hinge and pivots the mulch gate between the mulching position and a side discharge position. A baffle is removably attached under the mower deck and blocks a portion of a flow passage through the side skirt at the right of the right cutting chamber. | 10-30-2014 |
20140331634 | CONVERTIBLE MOWER DECK WITH MULCH ON DEMAND ACTUATOR - A convertible mower deck has a plurality of cutting chambers with a rotary cutting blade in each chamber and a side discharge opening from one of the cutting chambers, pivoting gates between the adjacent cutting chambers, and a pivoting side discharge door between a cutting chamber and the side discharge opening. Each of the gates and side discharge door are movable between a discharge or collection position and a mulching position. A mulch on demand actuator includes a switch in an operator station that causes a pivot control plate on a shaft to rotate and move linkages between the gates and door between the discharge or collection position and mulching position. | 11-13-2014 |
20150013298 | Mower Cutting Chamber With Adjustable Discharge Geometry - A mower deck includes at least one cutting chamber with a spindle-mounted rotary cutting blade.

In one embodiment, the cutting assembly includes an auger that compresses the grass clippings prior to cutting them. The mulching device may also include a separation chamber for separating the grass clippings from the forced air exiting the mower deck, so that the grass clippings may be cut in an environment separate from the forced air. In another embodiment, the mulching device includes a dispersion assembly for spreading the cut grass clippings onto a ground surface. The dispersion assembly may include a chute extending from the forced air outlet to a position adjacent the cutting assembly, wherein the forced air exiting the separation chamber is directed onto the cut grass clippings to disperse the cut grass clippings onto the ground surface. | 05-28-2015 |
