    摘要: The invention relates to wheeled raking machines which is rolled over the ground by a walking attendant. The raking device includes a raking head having a plurality of raking tines. The raking head is rocked back and forth to gather leaves ahead of the raking device. The rocking motion of the raking head is derived from a cam and linkage arrangement connected to the wheel. Thus, as the wheeled device is rolled over the ground the raking head is oscillated to rake the leaves.

    摘要: A sand trap rake mounted on the tractor comprising a transverse mounting member, a plurality of hitch elements spaced transversely of the mounting member and secured thereto and a Vshaped draft frame member connected to each hitch element, a rake connected to each frame member for floating movement therewith, each frame member having its apex adjacent to the respective hitch element and a universal connection fastening each draft member at its apex to the related hitch element and a toothed comb hung behind each rake for smoothing the sand, each frame being connected to the rockshaft in turn is connected to hydraulic lift of the tractor such that the operator in exiting from the sand trap may incrementally lift the rake to feather the action of the rake on the sand thereby preventing dragging it out of the sand trap.
