Farmall M with Disc Harrow STL 3D Print Model

The Farmall M is a legendary mid-20th-century row-crop tractor, and this highly detailed 3D printable set captures it pulling a full-width towed disc harrow with realistic coulter blades, seed hopper box, and dual-wheel axle extensions. The model includes both the tractor and the implement as separate components, making it ideal for dioramas, scale modelling displays, or tabletop farming scenes. Supplied as STL files ready for FDM or resin printing at your preferred scale. All major views — front, rear, side, top, and 45-degree angles — confirm the exceptional surface detail on the engine block, grille, seat, steering wheel, tyres, and harrow discs.

Print settings

FDM printing is recommended for larger display scales (1:35 or 1:32); resin printing will better capture fine tyre tread and disc blade detail at smaller scales (1:72 or 1:48). Print the tractor body and harrow frame separately, oriented upright or on their sides to minimise visible layer lines on flat panels. Use supports for the undercarriage linkage arms, the coulter blade assembly, and any overhanging cab/seat elements. An infill of 15–20% is sufficient for display pieces; increase to 30–40% if the parts will be handled regularly. PLA or ABS works well for FDM; standard grey resin is ideal for the fine surface detail visible in the renders.
