A multi-rotational concrete screed to produce a level finished surface that includes a frame assembly, a boom assembly secured to the frame assembly at a first end and to a screed head at a second end, and a drive assembly. A powered turntable is positioned between the frame assembly and drive assembly permitting complete rotation of each with respect to the other.

Surface-formation equipment includes a blade including a beam; and an attachment structure having a proximal end connected to the blade and a distal end configured to be attached to a mobile unit. The surface-formation equipment may also include a blade including a beam; and at least one lateral wing pivot-connected to one end of the main section, the at least one lateral wing being able to be configured in an unfolded configuration and at least one folded position. The surface-formation equipment may include a cutting edge secured to the beam near the lower surface.

This disclosure relates to an adjustable paving machine. In some examples, the adjustable paving machine includes a variably expandable portion. The variably expandable portion may be expandable laterally such as to accommodate paving operations of variable widths. The adjustable paving machine may be configured to spread a variety of paving materials on a paving surface, including oils, emulsions, asphalt, slurries, or the like. The adjustable paving machine may include a containment basin operative to contain a paving material such as to reduce lateral or longitudinal movement of the paving material. The adjustable paving machine may include an adjustable shoe configured to move the paving machine vertically relative to the paving surface. The adjustable paving machine may include one or more spreading elements configured to spread the paving material on the paving surface. The spreading elements may be supported by a spreading element support enabling easy replacement of the spreading elements.

A manual screed assembly has a screed bar assembly, a release assembly releasably coupled to the screed bar assembly, and a handle assembly releasably secured to the quick release assembly.

A self-propelled paving machine includes a plurality of swing legs, each swing leg being supported from a ground surface by an associated crawler track steerably connected to an outer end of its associated swing leg. The machine may be re-oriented from a paving orientation to a transport orientation via a transport conversion mode of an automatic controller configured to spin the paving in place on the ground through a re-orientation angle, then rotate each of the crawler tracks relative to its respective swing leg until each crawler track is primarily oriented in a transport direction generally perpendicular to the paving direction, and then while moving the paving machine in the transport direction pivoting each of the swing legs relative to the frame until each swing leg is oriented primarily in the transport direction. The paving machine may then be driven onto a transport vehicle.

An adjustable guided rake apparatus and method, which enable an adjustable guided rake user to configure an adjustable rake guide to a specified height in relation to a secondary surface, which will then define the height of the grading edge of the grading rake head in relation to a primary surface. The adjustable guided rake user is able to move the grading rake head along a primary surface, in order to shift material along the surface, while the adjustable rake guide runs along the secondary surface, guiding the grading rake head.

A drawbar assembly for a motor grader is provided. The drawbar assembly includes a yoke plate, a backbar, a drawbar tube, and a sleeve. The yoke plate includes a first surface and a second surface. The backbar is attached to the first surface of the yoke plate. The backbar includes a tube facing surface. The drawbar tube includes a first end and a second end. The drawbar tube is attached to the first surface of the yoke plate, defining a clearance between the first end of the drawbar tube and the tube facing surface of the backbar. The sleeve encloses at least a portion of the drawbar tube. The sleeve includes a backbar attachment portion and a yoke attachment portion. The backbar attachment portion is attached to the tube facing surface of the backbar and the yoke attachment portion is attached to the first surface of the yoke plate.

The present invention provides an adjustable guided rake apparatus and method which enables an adjustable guided rake user to configure an adjustable rake guide to a specified height in relation to a secondary surface, which will then define the height of the grading edge of the grading rake head in relation to a primary surface. The adjustable guided rake user is able to move the grading rake head along a primary surface, in order to shift material along the surface, while the adjustable rake guide runs along the secondary surface, guiding the grading rake head.

A paving machine which includes a containment basin. The containment basin has at least one brush therein to spread paving material onto a roadway surface.
