Grandpa's Tractor features a wood-fashioned muffler, engine block, hand crank, shifting levers, hitch bar in back, a free-turning steering wheel (does not control front wheels), with front wheels which turn and are secured by "tie rods". It's a sturdy, interesting, and one of a kind project that can truly be built by any skill level. Full size patterns are provided for all curved pieces, plus you get a list of materials, photos taken during construction, and crystal clear instructions. The finished tractor is about 45" long with a 20" seat height. Working parts are great imagination builders. You CAN build this project with this set of plans.
