Overview
The John Deere 3140, built from 1980 to 1987, combines a 359 ci (5.9 L) direct-injection engine with a Power Syncron transmission. Its 16 forward and 8 reverse gears give the model a clear driveline layout, while the 33.3-gallon fuel capacity is part of the core specification.
The hydraulic system uses a closed-center design with 12.4 gpm pump flow and 15.85 gal capacity. An independent rear PTO, 540/1000 speeds, and a hydraulic wet-disc clutch round out the working hardware.
