ABSTRACT:
A router machine for cutting a groove in pavement and the like for repairing cracks includes a pair of frame members mounting a shroud therebetween. A cutter head drive shaft is mounted by the frame members with axially spaced bushings keyed thereto within the shroud. Disks are bolted to the bushings. Circumferentially spaced cutter members are mounted to the disks, and include pins axially removably extended through apertures. Star bits and spacers are mounted on the pins. Retainers are pivotally mounted to the disks to selectively permit axial removable of the pins from the disks. A U-shaped mounting axle is pivoted to the frame members forwardly of the shroud for mounting ground engaging wheels. An operator guide handle is pivotally mounted to a console and operatively connected to brake members mounted by a brake axle to brakingly engage the ground engaging wheels when the handle cross bar is pushed downwardly. A combination skid plate and access panel assembly is pivoted to the shroud to move between an access position facilitating repairing the cutter head assembly and a closed position. A castor wheel assembly is removably mounted to the skid plate and access panel assembly for retaining the skid plate above the pavement.
