Abstract
657,687. Agricultural tractors. POBJOY, E. E., [Representative of Pobjoy, D R. J. March 8, 1948, No. 7027. [Classes 79 (i) and 79 (v) ] In an agricultural tractor having a single front steerable wheel a jury wheel is carried by the tractor frame in such a manner that one of the rear wheels and the jury wheel are alignable, the jury wheel being rigidly carried at the end of a non-steerable arm projecting transversely from a forward member of the tractor frame and pivoted thereto so that the wheel can be lifted clear of the ground when not required. As shown the tractor comprises a frame 4, the steerable wheel 5 of which is shown as a twin wheel and is mounted for castor action, and rear driving wheels 6, 7 mounted on splined shafts 11a. The arm 9 carrying the jury wheel 12 is pivoted on a pin 10 carried by lugs 8 on a bracket 19 secured to the frame 4. The arm 9 may be fixed in length or as shown may be adjustable by the arm being formed of telescoping parts 14, 13 secured together by a bolt 15. The arm 9 may be turned about the pivot 10 by manual or hydraulically operable means which comprise a hydraulic cylinder 17 pivoted on lugs 18, 20, flexible pipes 22, 23 leading to a hydraulic pump and control valve (not shown).
