In the operation of a landfill compactor it is a common problem for the wheels to pick up debris, especially wire and cable, and carry it around the wheel as they rotate. When the debris falls from the wheels in the direction toward the frame and the axles, it becomes packed between the frame and the axle hampering machine operation and requiring hours of corrective maintenance. The wheel assembly of the subject invention provides teeth that are positioned across the width of the wheel assembly in a plurality of rows. The outermost row is positioned adjacent the outer periphery of the wheel assembly while the innermost row is spaced from the inner periphery a preselected distance (X).

In the operation of construction vehicles, it is often desirable to quickly change from one work implement to another for various types of work. In order to accomplish this, adapting brackets or extensive support structure is added to the support arm and operating linkage of the vehicle to mount a specifically design work implement. Such designs have been known to alter the function of the operating linkages to a point where the performance of the work implement is sacrificed both in operational force capabilities and capacity. The coupling apparatus of the subject allows a plurality of work implements to be quickly coupled to and uncoupled from a vehicle. The coupling apparatus does so in a manner that maintains the operating geometry of conventional linkages and thereby maintains the appropriate operational forces needed for manipulation of the work implement with very little reduction in capacity from that of a convention work implement.

A hydraulic excavator having linkage providing for a front loading arrangement whereby the bucket opens away from the vehicle comprises power cylinders and linkage arranged to provide a balanced system providing maximum application of power and optimum use of power applied to the material-handling bucket. The power cylinders are connected to the linkage in a manner to utilize maximum leverage of the linkage when maximum power is needed.

An apparatus and method of preventing refuse from wrapping around the axle of a work machine is disclosed. A work machine includes a frame, an axle, at least one wheel, an operator compartment, an engine, and an axle protection system. The at least one wheel has a rim extension having an outer portion. The axle protection system includes a roof guard and an axle guard assembly. The axle guard assembly has a plate and a labyrinth guard. A channel is provided by the configuration of the guard assembly, plate, and labyrinth guard such that the outer portion of the rim extension is received by the channel. The plate extends substantially vertically from the perimeter of the axle guard assembly. Preferably, a flexible member is attached to the edge of the plate and extends such that it is urged in contact with the roof guard.

Among the variety of bucket arrangements that are commonly available, several are specifically designed for ripping applications in materials that are extremely hard to penetrate. While these types of buckets are normally satisfactory in ripping hard, strong, brittle materials, their designs do not lend themselves to excavating and dumping weaker more plastic materials and thus exhibit little or no versatility. The bucket arrangement of the subject invention includes a first and second ground penetrating means that are selectively positioned on the bucket with respect to each other. The selective positioning allows sole engagement of either of the first or second ground penetrating means with the ground or simultaneous engagement of both penetrating means with the ground. Such an arrangement provides superior operation in a ripping capacity and yet the selective positioning of the first and second penetrating means also permits excellent operation in weaker or plastic materials.

A cleaner module adapted for use on a compacting machine having (i) a compaction wheel and (ii) a pair of compaction tips secured to a peripheral surface of the compaction wheel such that the pair of compaction tips are spaced apart from each other so as to define a wheel space interposed therebetween is disclosed. The cleaner module includes a cleaner rod having a cleaning end. The cleaner module also includes a first bearing member which supports the cleaner rod. The cleaner module further includes an actuation mechanism operatively coupled to the cleaner rod for positioning the cleaner rod between an extended position and a retracted position, wherein (i) the cleaning end of the cleaner rod is located a distance D. sub. 1 from the peripheral surface of the compaction wheel when the cleaner rod is located in the extended position, (ii) the cleaning end of the cleaner rod is located a distance D. sub. 2 from the peripheral surface of the compaction wheel when the cleaner rod is located in the retracted position, and (iii) the distance D. sub.
