Frame suspension for rotary rakes and tedders

A suspension mechanism for a rotary rake implement incorporates elastomeric shock absorbing members in the corners of a tubular member situated in between the corners of a square rod formed as part of the wheel assembly and received within the tubular member such that the corners of the square rod assert a pre-load spring force on the tubular member when the implement is in an extended operating configuration. The movement of the implement into a folded transport configuration with the weight of the implement supported on the transport wheel assemblies causes a deflection of the square rod that compresses the elastomeric shock absorbing members within the corners of the tubular member to provide maximum suspension for the implement when in transport, while providing minimum suspension when the implement is in operation. An end cap on the square rod engages a stop formed on the tubular member to control rotation.

HAYMAKING MACHINE

A haymaking machine for tedding or raking agricultural stalk or leaf material includes a tedding or raking rotor arranged on a machine beam. The tedding or raking rotor is rotated about a vertical axis when working/operating. The tedding or raking rotor includes two tine arms aligned approximately radially which are uniformly distributed in a circumferential direction about the vertical axis, a first spring tine having a first length arranged on the two tine arms, a second spring tine having a second length arranged on the at least two tine arms, a first measuring device which interacts with the first spring tine, and a second measuring device which interacts with the second spring tine. The second length is smaller than the first length. The first measuring device measures a force acting on the first spring tine. The second measuring device measures a force acting on the second spring tine.

HAYMAKING MACHINE

A haymaking machine includes a frame, a turning or raking rotor and a sensor arranged on the frame, and a control device. In a working position, the turning or raking rotor is drivable relative to the frame about an axis of rotation in a direction of rotation. The turning or raking rotor has tine arms which have tines. The tine arms are aligned at least temporarily to face the ground. The tine arms are arranged uniformly distributed in a circumferential direction around the axis of rotation and are aligned in an approximately radial direction with respect to the axis of rotation. The sensor continuously detects a passing of the tine arms during an operation of the turning or raking rotor and transmits a measurement signal thereof. The control device receives the measurement signal and infers an operating state of the at least one turning or raking rotor based thereon.
