Abstract: A cast iron excavator bucket is provided that includes a first side wall, a second side wall, and a center wall interconnecting the first side wall and second side wall to form an inner cavity for receiving excavated materials, wherein the first side wall, the second side wall, and the center wall are integrally cast exclusively from iron.

Abstract: A rockshaft assist quick-attach apparatus for mounting a cantileverly supported implement, such as a backhoe, to a tractor, and also a method of using the tractor's rockshaft arms in conjunction with rockshaft arm receiving members, tractor brackets and implement mountable brackets to assist in attaching a cantileverly supported implement, such as a backhoe to the tractor. The apparatus comprising tractor brackets, rockshaft arm receiving members and implement mountable brackets. Wherein, when attaching the implement, the rockshaft arms are lowered to their down most position. The tractor is backed toward the implement until it is in close proximity and in substantial alignment fore and aft with the implement. The rockshaft arms are raised until the rockshaft arms engage the rockshaft arm receiving members. Further raising of the rockshaft arms causes upward movement of the implement.

Abstract: A machine (10) for forming material into cylindrical bales of density increasing from the center to the periphery, comprising a mobile structure (11) including first (14) and second (15) body portions pivotably secured together on a generally horizontal transverse axis, a baling chamber (20), in the structure, defined by portions of the peripheries of a plurality of closely spaced conveyors in the form right circular cylinders (21-39) mounted with their axes parallel and passing through points lying on a smooth closed curve in a vertical plane perpendicular to the axis, the lower half of the curve being generally a circular arc and the upper half departing outwardly from circularity by an amount which varies smoothly to and from a maximum in the vertical direction: a pickup mechanism (80-83) is provided for gathering material to be baled from the ground and introducing it as a ribbon peripherally into the chamber at its bottom, and a drive arrangement (17, 60-67, 70-73, 84, 85) is provided for causing operati
