Abstract

1500179 Tractor power lift linkages WESTLODE ENG Ltd 24 June 1976 [1 July 1975 15 July 1975 11 Oct 1975] 27706/75 29530/75 and 41713/75 Heading A1P The lower draft links 19a and 19b of the linkage are pivotally mounted by universal joints on a drawbar 10 which is connected to the tractor by a single vertical pivot pin 12. The lower links are supported by drop links 23, 31 which are telescopic and are connected to lift arms 4, 5 which are pivoted by rams 4c and 5c supported by pivot 8 on the flange 9 of a back plate 1 which can be rigidly secured to the tractor. An adjustable assembly 32 interconnects the lower links. The drop link 23 is adjustable by a pin and hole arrangement and also has a slot 30 to allow for floating movement; the drop link 31 is a hydraulic ram. The drawbar 10 is supported at its rear ward end by a plate 18, undeneath coupling lug 15, bearing on a plate 17 fixed to the rear surface of the back plate 1. The upper link 34 which is adjustable in length can be arranged to allow a floating movement and is pivotally mounted for vertical movement about a pin 43 secured to the back plate 1. The link can also pivot laterally being guided by ears 55.
