Tractor from UGEARS is a rattling greeting from the past century. No electronics, just plywood, rubber band motor and tons of fun! The motor has a transmission switch that provides three options: “park”, “drive” and “sport”. The “Drive” mode will get it going slowly, covering about 5 cm per second. Switch the model to “sport” to see your Tractor speeding up ahead! Self-assembled, no glue needed.
