1. A method comprising:
supplying power to a first hydraulic motor via a hydraulic power unit, the first hydraulic motor being attached beneath a first tank, and the hydraulic power unit being separate from the first tank, the first tank including:
a first top surface;
a first bottom surface opposite the first top surface;
a first wall fixed between the first bottom surface and the first top surface; and
a first aperture located in the first wall;
the first hydraulic motor being operatively coupled to a first scraper blade assembly including a first scraper blade rotatably coupled to the first bottom surface, wherein when the first hydraulic motor is powered via the hydraulic power unit the first scraper blade is rotatably displaced along the first bottom surface;
disconnecting the hydraulic power unit from the first hydraulic motor;
connecting the hydraulic power unit to a second hydraulic motor, the second hydraulic motor being attached beneath a second tank, the hydraulic power unit being separate from the second tank, the second tank including:
a second top surface;
a second bottom surface opposite the second top surface;
a second wall fixed between the second bottom surface and the second top surface; and
a second aperture located in the second wall;
supplying power to the second hydraulic motor via the hydraulic power unit; and
the second hydraulic motor being operatively coupled to a second scraper blade assembly including a second scraper blade rotatably coupled to the second bottom surface, wherein when the second hydraulic motor is powered via the hydraulic power unit the second scraper blade is rotatably displaced along the second bottom surface.
