The John Deere 3038E is a 4-wheel drive compact utility tractor. This model was manufactured from 2008 to 2021. The components of John Deere 3038E powerline system: Yanmar 3TNV86T 4-cycle three-cylinder direct injection turbocharged diesel engine and two-range hydrostatic transmission with infinite forward and reverse gears.

A 95.7 cubic inches (1.6L) engine has a cylinder bore of 3.39" (86 mm), piston stroke of 3.54" (90 mm), and maximum power of 36.7 hp (27.4 kW). The maximum forward speed - 6 mph (9.7 km/h) using low range or 14.1 mph (22.7 km/h) using high range, maximum reverse speed - 6 mph (9.7 km/h) using low range or 13 mph (21 km/h) using high range. The open center hydraulic system used a dual gear pump with a flow of 5.3 gpm (20.2 lpm). The hydraulic system pressure is 172 bar (2500 psi).

The John Deere 3038E is equipped with a hydrostatic power steering, wet disc brakes, 7.00x14 (AG) or 25x8.50-14 (Industrial) front tires, and 11.2x24 (AG) or 15-19.5 (Industrial) rear tires. The wheelbase is 62.8" (1590 mm). The tractor is compatible with a John Deere 305 front-end loader with lift capacity to full height of 1186 lbs (537 kg), or John Deere D160 front-end loader with lift capacity to full height of 1186 lbs (537 kg).
