Abstract
1,163,782. Tractor power lift mechanisms. KLÍCKNER-HUMBOLDT-DEUTZ A.G. 30 Sept., 1966 [29 Oct., 1965], No. 43791/66. Heading AlP. A lever 19 is moved to select whether the hydraulic mechanism responds to draft or position control signals. A link 32 transmits the signals to a main control slide valve 30, and a coupling member 20, having stops 21, 22 respectively engageable with a draft control rod 7 and a position control member 28, transmits the signals to the link 32. The member 20 is attached to the level 19 by link 15 whereby it can be swung between its signal transmitting position.
