UGears Tractor - 97 pieces (Easy) 

The UGEARS tractor is a rattling greeting from centuries past. No electronics - just plywood, a rubber band motor, and tons of fun! You can shift your tractor's real transmission from 'park' to 'low' to plow for your spring planting or step it up to 'sport' gear and watch it race to the end of the field.
