Build an awesome Excavator!

Construct your own authentic looking and functioning Excavator, complete with cool caterpillar tracks and a cab that really rotates. Make it a part of your construction crew!

  • Turn the knobs to control the excavator arm and bucket.
  • Includes step by step instructions to make a track-type tractor alternative model.


The main body of the model can turn 360 degrees on the track base, and the arm can be controlled by turning the two knobs on the back of the model. One knob is used to control the angle of the arm and the other to control the two joints in the arm. Due to both joints being manipulated at the same time, the scoop cannot pick up anything without the arm also moving. The model's mechanical actuator powered successor 8294 Excavator suffers the same problem with its arm, as it too uses only one actuator to change two joints.
