| 20100269471 | MAGNETIC CONNECTION OF DRIVING AND DRIVEN CONNECTION FOR A REEL MOWER - A rotating mechanical apparatus, such as would be used in a reel mower assembly, comprises a drive member rotatably mounted in a frame about a shaft axis. The drive member has a drive face oriented perpendicular to the shaft axis. A driven member has a driven shaft rotatably supported in the frame about the shaft axis, and a driven face oriented parallel to and bearing against the drive face. A bulb extends outward from one of the drive face and the driven face and into a corresponding recess in the other. Magnets force the drive face to bear against the driven face such that the driven shaft rotates with the drive member. One of the drive face and the driven face are movable along the shaft axis to disengage the bulb from the recess. A height adjustment mechanism moves ground rollers closer together or farther apart to vary cutting height. | 10-28-2010 |
| 20140075904 | Grass Collection System with Through-shaft PTO - A grass collection system may have an impeller with a through-shaft that mechanically couples power take off (PTO) energy to the mower deck. The PTO shaft may pass through the impeller and blower housing to power the mower deck, resulting in a compact mechanism. The PTO shaft may pass through a grass tunnel that connects between the blower housing and the mower deck, then may be connected to the mower deck to power the mower blades. The grass collection system may be deployed on a front mounted deck tractor that has front wheel drive. The front wheels may each have a hydrostatic pump and gearbox, and the PTO shaft may pass between or under the front wheel drive systems in connecting to the mower deck. | 03-20-2014 |
| 20160029557 | DRIVE SYSTEM FOR WALK BEHIND MOWER - A drive system of a lawn mower includes a drive belt, a drive pulley, a drive shaft pulley and an idler pulley. The drive pulley is disposed at a rocking transmission of the lawn mower to transfer drive belt motion to power for a set of wheels of the lawn mower via the rocking transmission when the rocking transmission is engaged. The drive shaft pulley is operably coupled to a drive shaft of the lawn mower to rotate responsive to rotation of the drive shaft. The drive shaft pulley engages the drive belt responsive to engagement of the rocking transmission. | 02-04-2016 |

| 20100031620 | Riding Type Mower - A riding type mower includes: a vehicle body, a driver's seat mounted on the vehicle body; an operation part arranged around the driver's seat; a mower unit provided on the vehicle body; a shutter for closing a discharge port; a shutter moving mechanism for moving the shutter between a close position closing the discharge port and an open position opening the discharge port; and a lock mechanism for locking the shutter at the close position. The mower unit includes: a mower deck; a cutting blade installed inside the mower deck; the discharge port formed in the mower deck, through which mown grass cut by the blade is discharge from the mower unit to outside. A shutter operating tool for remotely operating the shutter moving mechanism to open and close the shutter is provided in the operation part. The lock mechanism is remotely operable from the operation part. | 02-11-2010 |
| 20150113932 | ALL WHEEL DRIVE, WALK BEHIND MOWER - A drive system includes a first transmission, a second transmission and at least one flexible driving member. The first transmission is operably coupled to a first set of wheels to provide drive power to the first set of wheels responsive to engagement of the first transmission. The second transmission is operably coupled to a second set of wheels to provide drive power to the second set of wheels responsive to engagement of the second transmission. The at least one flexible driving member is operably coupled to a remote actuator and a drive shaft of the walk-behind outdoor power equipment device. The at least one flexible member selectively engages one of the first transmission or the second transmission to switch a walk-behind outdoor power equipment device between all wheel drive operation and another drive mode via the remote actuator. | 04-30-2015 |

The mechanism can include a sensor and at least one resilient member. The sensor can be rotatable about a sensor axis and can be in communication with a control unit, while the at least one resilient member can cooperate with the sensor to bias the sensor about the sensor axis. Furthermore, the control unit can be configured to control an operating state of a transmission of the walk-behind machine. In addition, the mechanism can be configured such that if the drive by wire control system becomes inoperative, a change in the operating state of the transmission occurs, such that the transmission is non-operational if the drive by wire control system becomes inoperative. | 04-28-2016 |
