other wheels as shown for example in fig4 the lifting mechanism may be of a manual nature including hand operated cranks not shown or can be hydraulic for simple automatic actuation by a switch positioned adjacent the driver 39 s seat a rearmost end of the frame comprises a pair of projecting portions of the side rails 11 and 12 the side rails are formed from tubular metal so as to define sleeves having a rear opening each of which can receive a stub shaft in sliding fit to latch the rear end of the frame to the stub shaft an axle the axle of the auger 21 which forms part of the auger is indicated at 24 and of the auger 21 is indicated at 24 and is of conventional construction the axle comprises a rigid elongate member upon which is rotatably mounted at respective ends one of a pair of ground wheels a forward or upper end of the auger is supported relative to the axle on a pair of upright struts 28 which are mounted on the axle and extend upwardly therefrom to an engagement with the auger tube as is well known the height of the upper end of the auger can generally be adjusted by movement of the struts 28 along the auger tube on a slide mechanism this slide actuation can be achieved by a winch and cable arrangement or by hydraulic cylinder as is conventionally known the vehicle therefore may include hydraulic actuation mechanism for causing actuation of the slide of the struts 28 relative to the auger tube for convenience of illustration the particular type of actuation mechanism is not shown as this is of a conventional nature the auger is driven by a hydraulic motor 212 and drive shaft.
