Demolition Tractor

The Demolition Tractor is an object that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was a machine employed by Dr. Robotnik as part of his campaign to destroy Knothole Village.

History
By planting a homing device on the amnesiac Sonic the Hedgehog, Dr. Robotnik planned to have the Demolition Tractors on his location once the Hedgehog found Knothole Village. However, thanks to the Knothole Freedom Fighters, Sonic regained his memory and turned Dr. Robotnik's scheme against him, luring the tractors to their destruction by leading them over a cliff edge.
