Task brief

Design a small LEGO farm tractor: a chassis sitting on four rubber-tyred wheels (two large rear wheels, two smaller front wheels, all on real wheel pieces with tyres), an engine block at the front, a single-minifig open cab with a seat and a steering wheel, and a body in green. The wheels must be attached via wheel-holder plates or axles, not just placed adjacent. Output a BOM.
