A combine harvester is provided with: a threshing device that performs a threshing process of threshing a crop; a grain tank that stores grain obtained by the threshing process; a grain discharging device that discharges grain to be stored in the grain tank to the outside of the vehicle body; a travel driving device that drives travel of the vehicle body; and an engine that serves as a power source. The combine harvester includes a first relay shaft to which power is transmitted from an output shaft of the engine, and the power of the engine is transmitted from the first relay shaft to the grain discharging device and the travel driving device in a branched manner.

A method and kit for extracting auxiliary power from a power source installed on or associated with an implement, and supplying the auxiliary power to an auxiliary tool associated with the implement. The invention is preferably employed in the context of an auxiliary tool, e.g., in the form of a rotary trimmer, edger or the like, associated with another power implement, such as a lawnmower, wherein the power is preferably extracted from a driven member of the implement. Advantageously, the device is easy to attach/detach, is universally locatable and/or orientable on the implement, and is easily retrofittable to practically any existing implement, such as a lawnmower deck.

A power take-off PTO connection mechanism (100) for mid mounted tools (101) of a utility vehicle (1000 includes three main assembly members: a frame attachment mechanism (108), a vertical moving frame (or cradle) (106), and a PTO assembly (128). The frame attachment mechanism (108) is fixed to the frame of the vehicle or tractor (1000). The PTO connection mechanism (100) of the present invention helps is easy and quick connection of the PTO shaft to a variety of tools (101) with the tractor. The PTO shaft remains in continuous contact with the tool power input once it is moved in an engaged position.

A harvester power takeoff (PTO) clutch system includes a detachable PTO extension module and transmission gearbox housing, which has a clutch compartment and a clutch service port through which the clutch compartment can be accessed. A PTO clutch is disposed in the clutch compartment, while a clutch shaft extends from the PTO clutch and projects from the clutch compartment through the clutch service port. The detachable PTO extension module includes, in turn: a PTO housing extension mounted to the transmission gearbox housing; a PTO shaft rotatably coupled to the PTO clutch and projecting from the PTO housing extension in a direction opposite the transmission gearbox housing; an inner extension bearing disposed in the PTO housing extension and rotatably supporting the clutch shaft; and an outer extension bearing further disposed in the PTO housing extension and rotatably supporting the PTO shaft.

A riding vehicle may include a blower assembly, a mower deck, and a power source. The blower assembly may be configured to direct air from an air inlet to at least one air outlet to move surface debris. The mower deck may be configured to cut a lawn formed of grass or other vegetation. The blower assembly may be configured to direct air to an interior space of the mower deck for assisted discharge of cuttings.

A yard maintenance device having a working assembly selectively rotatable based on operation of an engine of the device may include a belt drive system. The belt drive system may include at least one driven pulley operably coupled to the working assembly, a drive shaft operably coupled to the engine, a drive belt configured to selectively couple the drive shaft to the at least one driven pulley, a tension adjustment assembly, and a control unit. The tension adjustment assembly may be configured to operably couple to at least one component of the belt drive system to adjust a position thereof to modify tension of the drive belt. The control unit may be configured to provide electronic control of the tension adjustment assembly.

A drive system of a header for an agricultural vehicle. The header includes a plurality of driven devices. The drive system includes a shaft configured for conveying motive power from the agricultural vehicle to the header, a gearbox configured for being located on the header and for transferring motive power to the plurality of driven devices, and a torque damper. The torque damper is operably connected in between the shaft and the gearbox. The torque damper is configured for reducing a magnitude of a torque spike.

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.

A harvester power takeoff (PTO) clutch system includes a detachable PTO extension module and transmission gearbox housing, which has a clutch compartment and a clutch service port through which the clutch compartment can be accessed. A PTO clutch is disposed in the clutch compartment, while a clutch shaft extends from the PTO clutch and projects from the clutch compartment through the clutch service port. The detachable PTO extension module includes, in turn: a PTO housing extension mounted to the transmission gearbox housing; a PTO shaft rotatably coupled to the PTO clutch and projecting from the PTO housing extension in a direction opposite the transmission gearbox housing; an inner extension bearing disposed in the PTO housing extension and rotatably supporting the clutch shaft; and an outer extension bearing further disposed in the PTO housing extension and rotatably supporting the PTO shaft.
