Abstract

152,871. Pelling, E. R., and Mattick, V. A. Oct. 31, 1919. Addition to 116,131. Ploughs.-A motor plough which may also be used as a tractor is provided with side driving wheels and fore-and-aft steering wheels c carried by frame members b, c, and stays f. When the machine is to be used as a tractor the member c and its steering-wheel are detached, and the other steering-wheel is moved into a central position as in Fig. 4, its pivoted frame member b being stayed by a member w. In a modification, the frame-member b may be integral with the main frame so that the tractor steering-wheel is offset.
