Skid, the littlest yellow tractor in the equipment yard, wants to be mighty like the giant bulldozers, tall cranes and massive diggers who tower over him. But some of the big machines tell him he is just a dinky tractor with a putt-putt engine. While they are busy building a new road through the mountain, Skid is left behind to take out the garbage when disaster strikes.
