  • Patent number: 10701859
    Abstract: A control system for use with a turf maintenance vehicle. In one embodiment, the control system may provide a discrete engine speed input that may provide one engine speed command upon actuation, but result in additional engine speed commands depending on an actuation time of the input. In other embodiments, the vehicle may include an electronic controller (EC) providing resettable property statistics for one or more properties. In still another embodiment, the EC may provide a maintenance monitor onboard the vehicle that indicates maintenance status, when maintenance tasks are due or past due, and permanently records historical information regarding maintenance tasks. The maintenance monitor may further adjust a maintenance interval before the maintenance task is again due based upon inputs to the maintenance monitor.

  • Patent number: 9002585
    Abstract: A control system for electronically controlling engine speed and PTO clutch mechanism engagement of a grounds maintenance vehicle such as a lawn mower. In one embodiment, an electronic controller (electronic control unit or ECU) may receive operator inputs from a speed setting switch and an on/off PTO clutch engagement switch. The ECU may take these inputs and make intelligent decisions as to when to engage/disengage the clutch mechanism and may change engine speed automatically prior to, during, and/or after clutch mechanism engagement/disengagement. In one or more of these speed setting switch positions, the switch may set a speed of the engine to a first speed when the clutch mechanism is disengaged, and a second speed (different than the first speed) when the clutch mechanism is engaged.

  • Patent number: 7735305
    Abstract: A removable cover for attachment to a structure such as a housing. In one embodiment, the cover extends over a mechanical drive system of an implement. The exemplary cover may be used to shield a driven pulley and at least a portion of an associated belt of a lawn mower cutting deck when the cover is attached to the deck. The cover may, at one end, include one or more portions configured to engage the housing. At a second end, the cover may include a resilient lip that, at least in one embodiment, is defined by an opening formed in the cover. The lip may selectively interlock with an anchor attached to the housing to secure the cover relative to the deck.
