  • Bolt-on cutting apparatus
    Patent number: 6045201
    Abstract: In the operation of machines such as landfill compactors it is common to provide a shear assembly that is mounted between the axle assembly and a wheel that is rotatably mounted thereon to sever material that would otherwise become entrained about the axle assembly. Material of relatively large gauge may become lodged within the shear assembly and create large loading forces between the wheel and the axle components that have been known to damage various drive train components. The present invention provides a cutting apparatus that has a first (34) and second shear blade (40) mounted to the axle assembly (10) and wheel (12) respectively. The second shear blade (40) is bolted (66,68,70) to the wheel (12) in a manner wherein selected ones of the mounting bolts (66,68,70) are sized in a manner in which forces of a preselected magnitude will shear the bolts (68,70) thus limiting the amount of force transmitted to the drive train components.
