Abstract
A star-wheel rake including a frame, at least one front rake wheel and a rear drive wheel, coupled with each other so that the rotation of the rear drive wheel causes the rotation of the front rake wheel and connected to the frame so that the front rake wheel is lifted from the ground when the rear drive wheel is in contact with the ground.
Claims15
A star-wheel rake comprising:
- a frame (2;
- 302;
- 402);
- at least one raking unit fitted to the frame, each racking unit including at least one front rake wheel and a rear drive wheel, coupled with each other so that the rotation of the rear drive wheel causes the rotation of the at least one front rake wheel and connected to the frame so that the at least one front rake wheel is lifted from the ground when the rear drive wheel is in contact with the ground;
- and
- wherein the rear drive wheel and the at least one front rake wheel of each raking unit have rotation axes parallel to each other and transverse to a travelling direction (D) in a working configuration.
