The Kubota M5700 is a 2-wheel drive or 4-wheel drive utility tractor. This model was manufactured from 2001 to 2005. The components of Kubota M5700 powerline system: a 167.6 cubic inches (2.7 L) Kubota F2803-EA 5-cylinder indirect injection liquid-cooled diesel engine with a rated power of 61.6 hp (45.9 kW), and synchronized shuttle transmission with 8 forward and 8 reverse gears. The maximum travel speed (forward/reverse): 17.6 mph (28.3 km/h) and 5.1 mph (8.2 km/h).

The open center hydraulic system includes a gear pump with rated fluid flow of 10.9 gal/min (41.6 l/min). The hydraulic pressure is 195 bar (2830 psi). The Kubota M5700 is equipped with a hydrostatic power steering system, mechanical wet disc brakes, 7.50x16 (2WD) or 9.50x22 (4WD) front tires, and 16.9x28 rear tires. The tractor is compatible with Kubota LA1002 front-end loader with a lift capacity to full height of 2579 lbs (1169 kg) and breakout force of 3330 (1510 kg).
