Trim, Grade and Roll At the Same Time!

Burchland's Auto Grading Trimmer (AGT) is a skid steer mounted trimmer created for site work. The creation of this trimmer sparked from site work contractors because they wanted their equipment to be able to handle heavy duty construction work. The skid steer attachment is ideal for trimming sub-grade soil under building pads, parking lots, curbs, gutters, sidewalks, trails and roads. Its size makes it convenient to use on job sites.

The AGT allows contractors to cut the correct length for a clear finish and meet the minimum thickness of rock sub-base for a paving job. It will cut roughly one-tenth of a foot higher than the designed finished sub-grade. The trimmer cuts the sub-grade soil to the correct elevation with up to sub-centimeter accuracy. Once it's at the designed elevation and finished smoothly, the gravel sub-based can be added and trimmed by Burchland's AGT. By using this method, contractors know the amount of gravel and concrete they will need, so it saves time and material costs.

To ensure the skid steer trimmer will follow the surface grade precisely, a 3-D CAD surface file is uploaded to the machine controls. The machine—depending on the enabled controls—could follow Robotic Total Station, GPS or laser signals and can be operated in manual mode also.

The Burchland AGT's success stems from its 16-inch OD trimmer rotor that cuts an 8 foot wide path. The rotor is built with replaceable, carbide-tipped cutting teeth and 1/2 inch thick flighting that windrows the trimmed material to one side. The trimmer head is turned by a direct drive, large displacement hydraulic motor. Following a simple design, the AGT has no gearboxes or chain drives to maintain.

Behind the trimmer rotor is a grader blade edge that helps collect windrow material and provides a smooth finish. The rotor and grader blade are moved up and down with two hydraulic cylinders to precisely follow the designed 3-D surface elevation. The trimmer rotor and grader blade are angled 5 degrees from the direction of travel which helps trim the material.

Another important feature of the AGT skid steer trimmer is the 16-inch diameter smooth drum roller that smooths the imperfections. With the roller riding on the finished grade, the trimming operation is isolated from movement of the skid steer and skid steer loader arm. This helps the skid steer trimmer achieve a precise finish grade.

To provide the best performace, the Burchland AGT requires a high flow skid steer and a separate case drain line. Consult your skid steer dealer if your skid steer does not have a factory installed auxiliary case drain line.
