As best shown in Figs . 2, 3 and 4, the frame ( 24 ) comprises a pair of elongated side m~mbers t 59 ), ~ 61 ) 5 c~nverging at their front ends (Fig. 1) for the hitch (21), and diverging toward their rear ends such that they are joined by a rear member ~S2) for supporting the hopper 522) by means of the uprights (34) and support~ (36~, and supported slightly rearwardly vf the sump (23) by the wheels and axle unit (31),~32).
To aid in providing for the angular placement of the auger tube, indicated generally at (63) in Fig. 2 one side member (61) is bent outwardly at portion ~64) and then inwardly at the portion (66) in a V shape forwardly of a wheel (31), the tube t63) extended over and above the portions (64~,~66).
The auger unit ~33) includes the elongated auger tube ~63) comprised of an upper portion (67) and a lower portion ~68), the upper portion (67~ extended forwardly and sidewardly ~Figs. 2 and 3~ away from the hopper ~2Z) so as to have an angular relationship with the longitudinal and transverse axes of the hopper (22). It will be noted that the lower portion (68) is connected to the hopper wall curved portion (53) so as to be fixed therewith and ~hus is recessed into the hopper ~22).
The upper tube portion t67) comprises an upper section l693 pivotally connected by a conventional bell-crank unit ~71)~Figs. 9 and 10) to a lower section ~72)~ and with a discharge spout ~73~ at the outer end of the upper sectio~ (69), Referring to Figs. 7 and 8, the lower tube por~ion ~68) has a discharge opening (74) formed at its lower end, and is provided with a slide ~ate (76) for opening and closing the opening 35 ~74) S an elongated rod (77) having a pinion (78) on its inner end and operated manually by a handle ~7~(Fig.
