Abstract

1515725 Linkworks INTERNATIONAL HARVESTER CO 15 July 1975 [15 July 1974] 29610/75 Heading F2K [Also in Division B8] An hydraulically operated linkage assembly of a front end loader may be locked in a predetermined position by a lever 40 secured at one end to a bracket 70 on the linkage assembly and pivotally mounted at the other end to the loader frame, the latter end having a toe 58 which abuts a stop 56. The lever is secured to the bracket 70 by a bolt passing through apertures in the bracket and lever, the bracket also having a plate 72 which abuts top surface 66 of the lever to ensure a fully grounded condition. A bracket 60 is mounted on the loader frame to store the level 40 in an out of use position. The linkage assembly may comprise boom arms pivotally mounted to the frame to support the bucket, and a linkage to move the bucket relative to the boom arms.
