  • Patent number: 6338209
    Abstract: A trenching machine having independently driven wheels. Trenching machine comprises digging chain that moves between a raised position and a lowered position, a housing that is carried by a pair of front wheels and a pair of rear casters, a motor that independently drives front wheels to propel housing, and a guide wheel that aligns trenching machine with trench upon a second pass. Trenching machine also has a front plow and a rear plow that collect and deposit the dirt surrounding the trench into the trench. A method of gardening/landscaping wherein a trench is dug by a first pass, soil amendments are added to the trench, and then on the second pass, the excavated dirt is plowed back into the trench and then mixed with the amendments. A method of gardening/landscaping wherein vegetation cover between trenched rows is maintained thus utilizing only the ground area that is needed for planting.

  • Patent number: 6290009
    Abstract: When a conventional swivel working vehicle is constructed such that a real part of a swivel body is not extended beyond a traveling device in order to improve an operability at a small site, a balance weight must he significantly increased in weight so as to prevent falling and tumbling of a machine body. In the invention, left and right core metal projections of a crawler are laterally offset from a center line of the crawler and right and left lugs are formed on an outer peripheral surface of the crawler. The lugs are formed to assume the same shape on the right and left sides or laterally symmetrical shapes or occupy the same area on the right and left sides, and to be symmetrically shaped about a center of rotation of the swivel body between the left and right crawlers of the machine body.
