摘要： A conveyor apparatus can be (removably) secured to a turf maintenance machine and efficiently transport turf clippings out from a mowing implement of the turf maintenance apparatus. An opening in the conveyor apparatus defines an input that is positioned adjacent to a discharge port of a mow deck when secured to the turf maintenance machine. The input therefore receives turf clippings ejected by the turf maintenance machine. A driven element within the conveyor apparatus propels the turf clippings along an interior length to an output. The conveyor apparatus can be operable with a bagging mode of the turf maintenance machine, and can be removed and replaced with a discharge chute to implement a side discharge mode for the turf maintenance machine.

摘要： Selectively powered caster wheels for a maintenance apparatus are described. A motor attached to the caster wheel(s) can be selectively powered to apply force to the caster wheel. This force can be selected to overcome another force sensed at the maintenance apparatus, or to steer the maintenance apparatus on a desired course or direction. The caster wheels can be configured to orient along a direction of motion of the maintenance apparatus, in response to power from the motor or in response to the motion of the maintenance apparatus itself. In further embodiments, the motor(s) can be selectively activated or deactivated by an operator of the maintenance apparatus, in response to a remote control signal, or in response to an onboard or offboard controller of the apparatus.

摘要： Presented is a selective active caster steering apparatus for a maintenance apparatus having a first drive unit and a second drive unit. The selective active caster steering apparatus may comprise a caster wheel frame defining a caster swivel axis and a caster spin axis; a caster wheel operationally engaged with the caster wheel frame such that the caster wheel is adapted to be steered about the caster swivel axis; and a first caster steering unit adapted to selectably apply an amount of active torque to the caster wheel about the caster swivel axis as indicated by a first formula. The first formula may determine the amount of active torque to output as a first function of one or more measured parameters.

摘要： An autonomous mobile work system (20) includes a drive wheel (34) that is connected to a frame (24) and a rotating blade assembly (36). The rotating blade assembly (36) includes a blade assembly axis of rotation (38) and is connected to the frame (24) within a housing (26). The mobile work system (20) further includes a single motor (40) operably connected to the blade assembly (36). The motor (50) includes a motor output shaft (44) and the motor output shaft (44) includes an output shaft axis of rotation (46). The mobile work system (20) still further includes a gear box (50) operably connected to the drive wheel (34) and the motor output shaft (44). The single motor (50) urges rotation of both the rotating blade assembly (36) and the drive wheel (34). The gear box (50) can include a planetary gear set (104) including a ring gear (110) defining cavities (120) at its outside diameter (124). A locking shaft (126) can rotate between an engaged position and a disengaged position with one of the cavities (120).

摘要： A turf maintenance apparatus with an auger for transporting turf clippings out from a mowing implement of the turf maintenance apparatus can reduce power consumption for a bagging implementation for an electric-powered machine. In some embodiments, the turf maintenance apparatus can have an electric motor as a prime mover, or an electric motor for powering the mowing implement, or a combination of the foregoing. The auger can be powered by an electric motor and convey turf clippings, leaves, vegetation and other material expelled from a mow deck of the turf maintenance apparatus to a receptacle, bag or the like.

摘要： An air blowing apparatus having an auxiliary housing and auxiliary air flow output that can be selectively engaged and disengaged is described herein. In an embodiment of the disclosure, the auxiliary housing can comprise an auxiliary fan to generate a second high speed air flow to supplement a high volume air flow of a primary housing. When baffled, the auxiliary fan is isolated from air intake and can be driven with little power consumption. An air blowing apparatus can be a backpack-style apparatus or hand-held air blowing apparatus. As examples, one airflow can have a relatively high volumetric flowrate relative to another airflow, or can have a high air speed relative to another airflow, or can have a high energy relative to another airflow, and so forth.

摘要： A vertical tine tiller having vertically oriented tine assemblies that are configured to rotate about vertical axes is provided. The tiller includes a power source that drives a horizontally-aligned driveshaft, which can selectively drive a transmission assembly. Horizontal rotation of the driveshaft is directly transferred into vertical rotation of a pair of drive rods to which the tine assemblies are attached.
