John Deere 9RX Tractor with Disc Harrow STL 3D Print Model

The John Deere 9RX is a large articulated four-wheel-drive farm tractor rendered here in high-detail 3D printable form, paired with a full trailing disc harrow implement. The model captures the characteristic rounded cab, dual rear axle configuration, articulated hitch linkage, and the multi-gang disc harrow with transport wheels and frame bracing. Two cab versions are included: a solid-panel version and a windowed/lights version for added realism. Supplied as STL files ready for FDM or resin printing at your preferred display or diorama scale.

Print settings

FDM printing is recommended for the tractor body and main harrow frame using PLA or PETG at 0.15–0.2 mm layer height with 20–30% infill. The disc harrow arms, small hydraulic cylinders, and antenna are thin features that benefit from resin (MSLA/DLP) printing to preserve detail. Orient the tractor hood facing up and the cab square to the build plate; use supports under the chassis crossmembers and harrow gang brackets. Print the tractor and harrow as separate assemblies and join with CA glue.
