ABSTRACT:
Apparatus for routering a surface comprises a pair of independently driven drive wheels and a balance wheel which is freely pivotal to follow a path steered by the drive wheels. A cutting head is pivotally mounted between the drive wheels and its height relative to the surface may be adjusted to alter the depth of the router action. An operator's seat is located such that the operator has a relatively unobstucted view of the surface to be routed and the cutting head. A control for adjusting the height of the cutting head is provided adjacent the operator's seat, as are controls for the drive wheels. An improved cutting head assembly and cutting tool place are also disclosed, the cutting head assembly including a rotating shaft with a cutting head at one end, the shaft being orientated perpendicularly to the surface to be routered. The cutting head retains a diamond tipped cutting tool piece which rotates with the shaft to router the surface.
