A system and method for reversing a movement direction of a laterally extending conveyor of a draper header of an agricultural machine. The system includes a fluid line for delivering fluid to a motor that drives the laterally extending conveyor. A directional flow control valve is connected to the fluid line and is movable between a first state in which the directional flow control valve is configured to deliver the fluid to the motor in a first fluid direction to cause the motor to move the laterally extending conveyor in a first movement direction, and a second state in which the directional flow control valve is configured to deliver the fluid to the motor in a second fluid direction that is different from the first fluid direction to cause the motor to move the laterally extending conveyor in a second movement direction that is opposite to the first movement direction.

A pickup unit of an agricultural baler that includes a reel with a plurality of tines configured for lifting a crop material from a field, the reel is rotatable in an operating direction and a reverse direction, and a drive system configured for driving the reel. The drive system includes a gearbox configured for receiving motive power from a power take off (PTO) shaft, a drive shaft operably connected to the gearbox, and a first clutch connected to the drive shaft. The first clutch is configured for operably disconnecting motive power to the reel so that the reel is manually rotatable as the PTO shaft remains operably engaged with the gearbox.

A cutter bar assembly for an agricultural vehicle header includes a cutter bar supported by movable arms extending from a header frame and capable of operation in flex and rigid modes. The support arms are joined to the header frame such that they may be displaced from a raised position in the rigid mode when subjected to a lifting force due to striking an obstacle without damage to the header structure. Also, an agricultural vehicle header and an agricultural combine harvester includes the cutter bar assembly.

A regressive suspension spring system for a farm implement including a spring arm, a rocker arm, a wheel arm rotatably coupled to the farm implement at a first end and rotatably coupled to the rocker arm at a second end at a first pivot, one or more dogbone links rotatably coupled to the spring arm at a first end of the one or more dogbone links at a second pivot and rotatably coupled to the rocker arm at a second end of the one or more dogbone links at a third pivot; and a spring disposed between the rocker arm and the spring arm. An attachable farm implement including a regressive suspension spring system, such as a rotary cutter. A powered machine including a regressive suspension spring system.

A mower unit provided in a grass mower unit includes a mower deck having a top plate and a side plate extending downwards from the top plate, a rotational shaft extending through the top plate and rotatably supported to the top plate, and a blade attached to the rotational shaft inside the mower deck. A vibration detection unit is attached to the mower deck for detecting vibration in the mower deck. Vibration detected by the vibration detection unit is informed via an informing unit.

Harvesting apparatus, with a supporting frame (12) having a longitudinal member and crossmembers, with a chassis (18) having wheels (19), with pickup members (20) which are designed as a pickup and transverse conveyor devices (21) designed as belt conveyors, wherein a respective pickup member and a respective transverse conveyor device are arranged on a first and second side of the longitudinal member (13), wherein a first shiftable crossmember (14) which is arranged on the respective side of the longitudinal member and accommodates the respective pickup member (20) and the respective transverse conveyor device (21) is shiftable about an axis (24) extending in a height direction relative to a second shiftable crossmember (15) and is furthermore shiftable via the second crossmember about an axis (25) extending in the longitudinal direction relative to a fixed crossmember (16), and wherein a respective first overload protection device (26) is positioned between the first and second shiftable crossmembers (14, 15) arranged on the respective side of the longitudinal member (13), said overload protection device triggering when a force which acts on the respective pickup member (20) and/or the respective transverse conveyor device (21) and/or the respective first crossmember (14) in counter to the harvesting direction exceeds a limit value and permitting shifting of the respective pickup member (20) and of the respective transverse conveyor device (21) rearwards about the axis (24) extending in a height direction.

A method for controlled activation of cutting discs of row dividers of a machine for harvesting tall, stalky plants, such as sugarcane and sorghum. The method is used in a harvester machine including an operating cabin, at least one row divider equipped with at least one lollipop activated rotationally, and at least one cutting disc activated rotationally. The method includes steps of measuring a workload of the lollipops, comparing the workload of the lollipops with a predefined workload threshold in order to, thus, determine whether to reinitiate the measurement of the workload or to activate the at least one cutting disk.

In order to require as few load measuring units (50) as possible and yet always know the loads acting on the boom (3, 4) independently of the working head (2) currently attached to the boom (3, 4), the load measuring unit (50), in particular only one, is either on or in the boom (3, 4), in particular fixed, or between arm end (18a) of the boom and the head end (18b) of the working head (2) facing it.

A work machine comprises an engine, a work unit configured to be driven by the engine, a clutch provided between an output shaft of the engine and a power shaft of the work unit, and configured to transmit or cut off power from the output shaft of the engine to the power shaft, a sensor configured to detect an engine speed of the engine; and a control unit configured to control the engine and the clutch based on the engine speed of the engine. The control unit predicts, based on the engine speed of the engine detected by the sensor, whether or not the work unit will become locked by a load, and control the clutch to switch over from a transmission state to a cut-off state upon predicting that the work unit will become locked.

A lawn mower includes a blade assembly configured to perform a cutting function, a deck formed with an accommodation space for accommodating at least a portion of the blade assembly, a motor configured to drive the blade assembly to rotate about a rotation axis, and a battery pack configured to power the motor. The blade assembly includes a first cutting portion configured to cut grass and a second cutting portion configured to cut grass. In the direction parallel to the rotation axis, the second cutting portion is located under the first cutting portion. The battery pack includes a battery pack housing and battery cells provided in the battery pack housing.
