Retention system for attaching tool bits to a blade assembly
A tool bit includes a shank portion defining a longitudinal axis, a free end, and a perimeter, at least one anti-rotation feature on the perimeter extending to the free end, and a cross-hole defining a cross-hole axis along which the cross-hole extends through the shank portion. The tool bit also including a working portion extending downwardly axially from the shank portion. The working portion includes a rear region, a front working region defining a width with a midpoint, a first side region and a second side region. The first side region and the second side region define an angle of extension measured in a plane perpendicular to the longitudinal axis. The cross-hole axis pass through the width of the front working region when projected onto a plane perpendicular to the longitudinal axis.
