Claim 16:
17. A method of profiling a surface, the method comprising:
positioning a cutter drum against the surface, the cutter drum comprising:
a cylindrical body extending along an axis from a first end to a second end, the cylindrical body including a circumferential outer surface encircling the axis;
a plurality of cutter mounts attached to the circumferential outer surface of the cylindrical body;
a plurality of rotary cutters secured to the cylindrical body, wherein each rotary cutter is rotatably coupled to a respective cutter mount of the plurality of cutter mounts; and
a plurality of carbide picks secured to the circumferential outer surface of the cylindrical body, each of the carbide picks having a fixed position relative to the circumferential outer surface of the cylindrical body,
wherein a ratio of the number of rotary cutters to the number of carbide picks on the cutter drum is at least 4,

rotating the cutter drum against the surface such that the rotary cutters and carbide picks engage the surface and remove portions of the surface.
