  • Utility device having an improved rotatable drive mechanism
    Patent number: 6865827
    Abstract: A utility vehicle or other device for excavating soil or the like includes a utility mechanism, such as, e.g., a trencher, an auger or the like, with a motor-driven utility drum. In preferred embodiments, the motor is contained substantially entirely inside the drum. Preferably, the drive shaft is operatively connected to the drum to rotate the drum at a connection location that is displaced inward from ends of the drum. In some embodiments, the drive shaft is also preferably operatively connected to a second utility mechanism, such as, e.g., a trencher chain. In some embodiments, a planetary transmission is also located inside the drum.
