ABSTRACT:
A road repair tractor adapted for smoothing asphalt that has been laid into a work-trench, dug in a roadway. The tractor includes a body supporting an engine and defining a cockpit. Also, laterally spaced first and second support and motive force assemblies are operatively driven by the engine and support the body. A smoothing device is supported by the body and has a width that is adjustable from a most narrow width of between 10 cm and 30 cm to a widest width of between 1 meter and 2.5 meters. The smoothing device also includes a smoothing blade assembly, having a bottom edge, deployed between a pair of asphalt side-spill guards. Finally, a power actuating system includes controls located in the cockpit that permit a user seated in the cockpit to change the adjustable width of the smoothing device and to raise and lower the smoothing device relative to the body.
