Tedder with adjustable rake rotors

A tedder having a main frame intended for suspension from a tractor and a carrier beam which is pivotally connected to said main frame for pivotal movement about a horizontal axis, a plurality of rake rotors, which are rotatable about their respective substantially vertical axes, being suspended from said carrier beam, each of said rake rotors being supported by a travelling wheel whose height position with respect to the carrier beam is adjustable by means of a height adjustment means slidable in parallel with the rotor axis, said tedder having an angle adjustment mechanism preferably activatable from the driver's seat of the tractor to pivot the carrier beam, characterized by an angle lever which is rotatable about an axis stationary with respect to the carrier beam, one arm of said angle lever being connected with a member, said member being part of the angle adjustment mechanism and stationary with respect to the main frame, so that movement of the carrier beam with respect to the main frame causes rotation of the angle lever, the other arm of said angle lever being connected with the height adjustment means for displacing said height adjustment means and travelling wheel upon rotation of the angle lever.
