The seat turns a full circle, so a child can dig on one side and dump on the other without climbing off, which is how a real excavator works. A trapezoid base keeps the machine planted while the arm is loaded, and rubber handles give a firm grip on the levers. Carbon steel with plastic fittings weighs 10 lbs and carries a 110 lb rider aged four to twelve. Overall 34.6" x 13" x 17.2". Suits a sandbox, beach or garden.
