  • Patent number: 7066682
    Abstract: Vehicles and methods provide for a single vehicle that has both loading ability to grade and otherwise move dirt while also having the ability to compact soil. One or more compaction wheels are included on a vehicle such as a skid steer loader. Wiper bars are also included to clean circumferential grooves defined by compaction studs located about the periphery of the compaction wheels. The compaction studs have a substantially flat ground-contacting surface with a surface area significantly smaller than the typical contact area of a tire, which results in increased pressure to provide for soil compaction. A loader bucket of the vehicle may be elevated to various heights to alter the weight distribution applied to the compaction wheels and/or may be filled with material such as dirt to control the overall vehicle weight applied to the compaction wheels.
