A kill switch including a switch assembly. When the switch assembly moves from a switch first configuration to a switch second configuration with the switch assembly operatively connected to a controller of a tractor, a kill electrical signal is provided to the controller to stop the tractor powering a power take-off thereof. A cord is securable to the switch assembly and to the piece of machinery to extend along a rotary drive shaft between the tractor and the piece of machinery. A switch actuating element extends from the cord, the switch actuating element being removably securable to the switch assembly. In the switch first configuration with the switch actuating element secured to the switch assembly, the switch actuating element maintains the switch assembly in the switch first configuration. When the switch actuating element is removed from the actuating element receiving portion, the switch assembly moves to the switch second configuration.

A method for maintaining an engine speed of an engine of a work vehicle includes sending a requested parameter indicative of the engine speed to an engine controller of the work vehicle. The method also includes receiving a measured parameter indicative of the engine speed. The method further includes determining whether the requested parameter is different from the measured parameter. The method also includes setting a controller-requested parameter indicative of the engine speed based at least in part on the requested parameter and the measured parameter. The method further includes sending the controller-requested parameter to the engine controller. The method accounts for speed and torque saturation in order to avoid windup in the controller.

A connection arrangement for use in a forage harvester between a feed roller and a gear box of a forage harvester is disclosed. A gearbox shaft with a central through bore is rotatingly supported in a gearbox housing around an axis of rotation, an outer surface of a distal end of the gearbox shaft being provided with ridges. A feed roller shaft is rotatingly supported around the axis of rotation, the feed roller shaft having a central blind bore aligned with the central through bore of the gearbox shaft, an outer surface of a distal end of the feed roller shaft being provided with ridges. A connecting shaft is located within the central bores of the gearbox shaft and the feed roller shaft. A sleeve having internal splines is provided, surrounding the distal ends of the gearbox shaft and the feed roller shaft. The splines of the sleeve match the ridges of the gearbox shaft and the feed roller shaft so as to provide torque transmission between the gearbox shaft and the feed roller shaft. A locking element secures the splined sleeve axially in position about the distal ends of the gearbox shaft and the feed roller shaft.

A vehicle may operate in a first mode in which rear traction members of the vehicle are driven forwardly by an electric motor and a hydraulic pump is powered and may alternatively operate in a second mode in which the rear traction members are driven forwardly by the electric motor while the electric motor is operably decoupled from the hydraulic pump. A controller determines a state of an implement attached to the vehicle, a present or forthcoming turning state of the vehicle, a geo-referenced location of the vehicle, a slip of the vehicle, and/or a camera captured image of terrain. The controller outputs a recommendation for either the first mode or the second mode based upon the determination or automatically switches between the first mode and the second mode based on the determination.

A combine harvester with a feeder house assembly, the assembly including a feeder house with an inlet end; a tilt frame surrounding the inlet end of the feeder house and in pivotal arrangement relative to the feeder house; a gearbox attached to the tilt frame; and a first dog clutch operably coupled to the gearbox.

A drive shaft (1) includes a telescopic shaft (3) having an outer tubular shaft (9) and an inner tubular shaft (11) inserted slidable into the outer shaft (9). A lubrication system is further provided, including: a lubricant receiving chamber (39) housed in the inner shaft (11); a lubricant distribution block (41) housed in the inner shaft (11); lubricant supply ports (11.9) for supplying lubricant from the lubricant distribution block (41), through a tubular wall of the inner shaft (11), towards a gap between the inner shaft (11) and the outer shaft (9); at least a lubricant transferring duct (47.1; 47.2) from the receiving chamber (39) to the distribution block (41). wherein the supplying ports (11.9) are distributed in at least two positions offset in direction of the axis (A-A) of the telescopic shaft (3).

A PTO support assembly for a work vehicle train includes a work vehicle having a PTO drive shaft and a work implement, towed by the work vehicle, having a PTO shaft. The PTO support assembly has a mounting base with a connection interface coupled to the work implement. A support member is coupled to the mounting base and has a support interface for contacting the PTO shaft. The PTO support is adjustable to a support position in which the support interface is maintained at a height corresponding to a height at which the PTO shaft is engaged with the PTO drive shaft.

A tractor implement configured to be towed by a tractor includes a gearbox comprising an input shaft and an output shaft, a mechanical clutch coupled to the gearbox, an actuator coupled to the mechanical clutch, and a driveline coupled to the gearbox via the mechanical clutch. The actuator is controllable to move the mechanical clutch to selectively engage and disengage the output shaft with the driveline.
