    摘要： A spring tooth harrow comprising an elongated tool bar having a plurality of harrow sections secured thereto by adjustable mounting brackets to enable the harrow section to be raised or lowered with respect to the draw bar. Each harrow section includes a pair of longitudinally extending arms which are pivotally secured to the mounting brackets and which are urged downwardly with respect thereto by pairs of springs. Fork pipes are rotatably mounted on the arms and extend therebetween and have spring teeth secured thereto. The pipes may be rotatably moved in unison to change the angle of attack of the spring teeth or the forwardmost pipe may be independently rotated with respect to the remaining pipes so that the angle of attack of the forwardmost spring teeth may be varied with respect to the trailing spring teeth.

    摘要： A wheeled spring tooth harrow has pivoted wing frames, each of which is movable between operating and transport positions by a hydraulic wing fold mechanism which folds the wings through 155* or more from a position in alignment with the main frame. The wing fold mechanism includes a pair of links having a lost-motion connection which, as the wing is being folded to the transport position, permits the wing to free-fall from a balanced position at approximately 110* closed through approximately 15* and, as the wing is being opened to an operating position, permits the wing to free-fall from the balanced position through approximately 20*. When the wing is in the operating position, the lost-motion connection permits the wing to float through approximately 35* to follow ground contour.

    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.
