Electrically Powered Flail Mower

A flail mower assembly includes a deck having a shaft rotatably connected to the deck. A flail drum is connected to the shaft and is co-rotatable with the shaft. A plurality of flail blade assemblies is independently rotatably connected to the flail drum to provide two degrees of freedom-of-rotation of each of the plurality of flail blade assemblies independent of a direction of drum rotation. First and/or second electric motors are connected to the deck and rotatably connected to the shaft. The shaft is rotated by an energized one of the first or second electric motors or both energized simultaneously. A load connected to the first and second electric motors when the first and second electric motors are de-energized reduces a rotational velocity of the flail drum.

Regulated Output Voltage Generator-Set Applied To Mobile Equipment in the Turf Industry

A turf maintenance vehicle includes an internal combustion engine and an energy converting device that converts mechanical energy from the engine to electric energy. The vehicle also includes at least one subsystem powered by the electric energy from the energy converting device. The vehicle further includes a demand sensor that detects electrical demand from the subsystem. Also, the vehicle includes a controller that changes a speed range of the engine based on the electrical demand, which changes the operating voltage range output from the energy converting device. A method of operation of the vehicle is also disclosed.

Electrically Driven, Reel-Mower Accessories

Real-mower accessories according to the present teachings are electrically driven. The electrically powered accessories use electric motors that can be operated independently of the transport wheels of the mower. Electrically powered accessories can use the on-board power source of the mower to which it is attached along with the control assembly thereon. The electrically powered accessories enable rotational rates and direction of rotation of the components of the electrically powered accessories to be easily adjusted and changed independently of other components of the mower. The electrically powered accessories can provide a more efficiently powered accessory. The electrically powered accessories can allow a user to independently verify the speed and direction of the electrically powered accessory relative to the other electrically powered accessories or other electrically driven components of the mower.

Greens mower data display and controller

A turf maintenance vehicle, wherein the vehicle includes a traction drive system structured and operable to provide movement of the vehicle across a ground surface, and an electric motor structured and operable to provide rotation of a cutting device that includes a plurality of cutting blades. The vehicle additionally includes a vehicle controller that is configured to receive a programmable vehicle clip rate data input and monitor a groundspeed of the vehicle and a rotational speed of the cutting device as the vehicle moves across the ground surface. The controller is additionally configured to actively control the electric motor based on the monitored vehicle groundspeed to thereby actively control the rotational speed of the cutting device in order to maintain the programmed clip rate of the vehicle as the vehicle moves across the ground surface.

Articulating handle for a walk-behind mower

A walk-behind greensmower includes an operator presence control for selectively determining when power from a source is delivered to an output. The operator presence control includes a handle, a bale coupled to the handle, a control arm and an electromagnet. The bale is moveable between an engaged position and a disengaged position. The control arm is moveable between a neutral position and a drive position where the control arm causes delivery of power from the source to the output when in the drive position. The electromagnet is selectively energizable in response to the position of the bale such that the control arm is retained in the drive position when the bale is in the engaged position.

Regulated output voltage generator-set applied to mobile equipment in the turf industry

A turf maintenance vehicle includes an internal combustion engine and an energy converting device that converts mechanical energy from the engine to electric energy. The vehicle also includes at least one subsystem powered by the electric energy from the energy converting device. The vehicle further includes a demand sensor that detects electrical demand from the subsystem. Also, the vehicle includes a controller that changes a speed range of the engine based on the electrical demand, which changes the operating voltage range output from the energy converting device. A method of operation of the vehicle is also disclosed.

Operator prescence control via a bale coupled to a handle and control arm, typically for electric reel mower

Bale 92 is coupled to handle 90 and is movable to an engaged position. Control arm 52 is movable to a drive position where it causes delivery of power from a source to an output (not shown). Electromagnet 72 is selectively energisable in response to the position of bale 92 and control arm 52 is electro-magnetically retained in the drive position while the bale is in the engaged position.

Operator control assembly with a tilt mechanism pivotally interconnecting a handle and a support arm

An operator control assembly for a turf grooming device includes a support arm adapted to be coupled to the turf grooming device that extends from the turf grooming device at a first angle, a handle and a tilt mechanism pivotally interconnecting the handle and the support arm. The tilt mechanism is operable to selectively fix the position of the handle relative to the support arm at a second angle. (62) Divided Out of 528430
