Abstract
A cultivator tine and mounting includes an elongated tube support that rotates about an upwardly extending shaft that is secured to a bracket at the upper central portion on the support. Each end of the support is closed by tine holders having vertical passageways with tapering surfaces to secure upper fastening portions of the tines. Each tine includes a soil-working portion which is integrally joined to the working portion. A collar with a conical surface is located adjacent and above the juncture. Also, projections on the tine immediately adjacent the collar extend laterally beyond the collar and the projections are received in their holders.
Claims6
A tine for a rotary harrow, comprising an upper fastening portion and a lower soil-working portion, said fastening portion and said soil-working portion each having a longitudinal axis, the longitudinal axes of the portions being angled with respect to one another, said fastening portion comprising an upper threaded end portion adapted to receive a fastening nut, a collar having an encircling upper conical surface, an integral junction between said fastening and said soil-working portions, said collar being positioned immediately above said junction, said conical surface facing said threaded end portion, integral projection means on said tine, said projection means being located adjacent said collar and extending laterally beyond the periphery of said collar and in a direction substantially perpendicular to a plane extending through the longitudinal axis of said fastening portion.
A cultivator tine mounting comprising an elongated substantially horizontal hollow support having a generally cylindrical tine holder at each end of said support, each tine holder comprising a substantially vertical passageway with upper and lower ends shaped to define, respectively, downwardly and upwardly tapering conical surfaces, said holders being connected to the outermost ends of said hollow support and said outermost ends terminating in said holders, an upwardly extending shaft connected to said support at the upper central region thereon, said shaft defining an axis about which said support is rotatable, and said shaft being connected to said support with a semi-circular bracket which embraces said upper central region.
