【正文】 accordance with the size of the beet. A hood 3i is supported from the fixed braces 23 to prevent the beets from passing over the wheels. Should an unusually high beet be encountered or should the plows lift the beets to an unusual height, their crowns will strike this hood and be guided thereby rear wardly between the lifting wheels. It is desired to call particular attention to the construction of the lifting wheels. Each consists of a hub member 32 provided with a plurality of radial spoke sockets. Spokes 33 extend radially outward from the hub member to a connection with resilient rim plates 34. The rim plates support a pair of corrugated hoops 35 which form the two side edges of the wheel. The upper hoop is of smaller diameter than the lower hoop so as to impart a frustoconlcal shape to the wheel. The two hoops are connected together at the high points of their peripheries by means of cross bars 36. The corrugations in the hoops allow them to conveniently engage the rounded sides of the beets, thus forming beetreceiving pockets, and the open spaces between the cross bars permit the rounded sides to project into the wheels to be firmly gripped will be noted that the hoops 35 and the cross bars 36 are members of small diameter, in the nature of rods, and by virtue of this construction the area of contact between the lifting wheels and the beet there between is quite small. This has the advantage that, without requiring excessive spring pressure, encrusted soil, clods and the lie clinging to the beet are broken and fall away from the beet, yet the pressure with which the wheels engage the beet is not great enough to damage it. While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention. Having thus described the invention, what is claimed and desired secured by Letters Patent is:1. A lifting wheel construction for beet harvesters for engaging beets and directing them with increased velocity toward a point of reception, said wheel construction prising: a hub member。Fig. 4 is a top view of one of the wheels removed
