Abstract
710,810. Agricultural implements. NORDSTEN, M., [trading as NORDSTEN, HILLEROD JERNSTOBERI OG MASKINFABRIK VED M: NORDSTEN, P.]. April 30, 1952 [May 2, 1951], No. 10847/52. Class 6 (1) A device for lifting and lowering marker arms 11 on an implement comprises a lifting lever 2 which actuates two bell crank levers 8 attached to the marker arms 11 through links 10 and links 4 provided with slots 6. Spring operated pawls 13 lock the marker arms in the raised position and are provided with arms 15 which are moved to disengage the pawls from the levers 8 by means of levers 18 operated by a Bowden control and pivoted on a member 17 which raises and lowers the implements the arrangement being such that when the member 17 moves in the direction of arrow 22 to lower the implements, levers 18 may be operated selectively to disengage one of the pawls 13 and so lower the required marker arm. The slots 6 allow the lowered arm to be raised although the remaining arm is locked in the raised position.
