摘要： A shovel blade comprises a body portion having an elongated socket at its rearward end and a digging portion integral with the socket and extending laterally outwardly and forwardly therefrom. The socket has a predetermined straight portion of longitudinal extent. The digging portion includes peripheral edges having rearward sections extending outwardly from opposite sides of the socket. The rearward sections include a pair of longitudinally extending slots spaced on either side of and substantially adjacent to the socket. The peripheral edge extending laterally outwardly from each slot is bent at a substantial right angle to form a platform step.

摘要： A wheel assembly includes first and second wheel halves each having an outer annular rim with a valley portion and an integral wall with external and internal surfaces. Each wheel half is shaped at its center to form an opening extending through said wall, with the wall defining the opening including a flange like portion extending in a direction normal to the plane of the external surface of said integral wall. The wall defining opening functions as an annular bearing seat. A bearing includes a pair of spaced generally cylindrical flanges of a first diameter joined by a generally cylindrical intermediate portion of a diameter somewhat smaller than the first diameter. The cylindrical flanges of the bearing are supported by the walls defining each opening. First antirotation elements are affixed to the bearing and second antirotation elements are affixed to the first and second wheel halves to cooperate with the first antirotation elements for substantially preventing rotation of the bearing relative to the walls defining each opening. The first and second wheel halves are joined to form a complete wheel assembly.

摘要翻译： 轮组件包括第一和第二轮半部，每个轮半部具有带有谷部分的外部环形边缘和具有外部和内部表面的整体壁。 每个车轮半部在其中心处成形以形成延伸穿过所述壁的开口，其中限定开口的壁包括沿垂直于所述整体壁的外表面的平面的方向延伸的凸缘状部分。 壁形开口用作环形轴承座。 轴承包括一对第一直径的间隔开的大致圆柱形凸缘，该凸缘通过直径略小于第一直径的大致圆柱形的中间部分连接。 轴承的圆柱形凸缘由限定每个开口的壁支撑。 第一防旋转元件固定在轴承上，第二防旋转元件被固定到第一和第二轮半部以与第一防旋转元件协作，以基本上防止轴承相对于限定每个开口的壁的旋转。 第一和第二半轮连接以形成完整的轮组件。
