A haymaking machine has a rake rotor with frame and support arm provided with a base part and a sliding part. The base part is pivotably connected to the frame about a support arm axis to enable the support arm to pivot between a lowered active position and a raised passive position. The sliding part is slidable relative to the base part between an inner position and an outer position for length adjustment of the support arm. The outer position is farther removed from the support arm axis than the inner position. A catching element is connected to the sliding part. A linear drive is connected to frame and sliding part to move the sliding part into the inner position and pivot the support arm from active position into passive position. A retaining mechanism holds the support arm in active position until the sliding part has reached the inner position.

An agricultural rake assembly includes a frame. A plurality of wheels is coupled to the frame. A shaft is coupled to and extends upwardly from the frame. A pair of disks is rotatably coupled to the shaft. The disks are rotated when the wheels are rotated. A cam track is coupled to the shaft. A plurality of rake arms are each movably coupled between the disks. The plurality of rake arms is distributed around the disks. A plurality of rakes is coupled to each of the rake arms. The rakes may engage a crop. A plurality of cam arms is each movably coupled between the rake arms and the disks. The cam arms each urge the rake arms between a raking position, a lifted position and a lowered position when the first end of the associated one of the rake arms moves along the cam track.

A system includes an agricultural raking vehicle, including a motor drive and raking members mechanically coupled to the motor drive. The raking members rake agricultural product via rotation about an axis substantially orthogonal to a field on which the agricultural vehicle travels. The system also includes a sensor assembly that outputs a signal indicative of a determined windrow quality of the agricultural product raked by the raking members. The system also includes a controller communicatively coupled to the motor drive and to the sensor assembly. The controller receives the signal and controls an angular speed of the motor drive, a ground speed of the agricultural vehicle, and/or a height of the raking members or tines above the field, based on a comparison of the determined windrow quality to a target windrow quality.

A raking machine includes a traveling vehicle, a rake coupled to the traveling vehicle to rake grass in an agricultural field and form a swath, a sensor to obtain a state of the grass or the swath in the agricultural field, and a controller to change, when the rake performs raking, setting information regarding the rake based on the state obtained by the sensor.
