Abstract

876,260. Tractor power-lift mechanisms; controlling vehicles. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN Ltd. Feb. 6, 1958 [April 15, 1957], No. 4124/61. Divided out of 876,258. Drawings to Specification. Classes 79(1) and 79(5). The subject-matter is as described in Specification 876,258 but the claims relate to the clutch release in the tractor drive which is operated hydraulically by fluid pressure in the power lift system under the control of valve means actuated by a draft-responsive member.
