Kirovets K-744 Tractor with Disc Harrow STL 3D Print Model

The Kirovets K-744 is a large Russian articulated four-wheel-drive farm tractor, here paired with a multi-section disc harrow and seed drill implement for a complete tillage and seeding setup. The 3D model captures exceptional mechanical detail across both vehicles, including the tractor’s distinctive rounded cab, dual rear axles, hydraulic linkage arms, coulter discs, packer rollers, and seed hopper modules. Designed for display, diorama, and scale modeling purposes, the set is suitable for FDM or resin printing and is delivered in STL format ready to slice. Two cab variants are included: a solid-roof version and a windowed/lights version for added realism.

Print settings

FDM printing is recommended for larger subassemblies such as the tractor body, seed hopper, and harrow frame, using PLA or PETG at 0.15–0.2 mm layer height with 20–30% infill. Resin printing (MSLA) is strongly recommended for the fine mechanical parts: coulter discs, seed tubes, hydraulic cylinders, and packer roller sections, to preserve sharp detail. Print the tractor and implement as separate sub-parts and orient elongated components (toolbar, packer bar) horizontally to minimize supports. Supports are required for overhanging cab roof elements, axle housings, and the underside of the harrow frame.
