John Deere 2320 Troubleshooting

The John Deere 2320 compact utility tractor was manufactured from 2006 to 2012. The components of John Deere 2320 driveline system: Yanmar 3TNV76 4-cycle three-cylinder indirect injection liquid-cooled diesel engine and two-range hydrostatic transmission with infinite forward and reverse gears.

A 68.1 cubic inches (1.1L) engine has a cylinder bore of 2.99" (76 mm), piston stroke of 3.23" (82 mm), and maximum power of 24.1 hp (18 kW). Max forward speed - 11.3 mph (18.1 kph), max reverse speed - 11 mph (17.6 kph).

The open center hydraulic system used a dual gear pump with rated capacity of 3.4 gpm (13 lpm). The main relief pressure is 167 bar (2420 psi). The John Deere 2320 is equipped with a hydrostatic power steering, wet disc brakes, 23x8.50-12 front tires, and 31x12.00-16.5 rear tires. The wheelbase is 63" (1600 mm). The tractor is compatible with a John Deere 200CX front-end loader with lift capacity to full height of 902 lbs (409 kg) and breakout force of 2239 lbs (1015 kg).
