Case IH DX25E Troubleshooting
The
Case IH DX25E sub-compact utility tractor was manufactured between 2005 and
2007. The Case IH DX25E driveline consists of Shibaura S773 three-cylinder
liquid-cooled diesel engine, and hydrostatic transmission with infinite forward
and reverse gears.
A 61.3 cubic inches (1 L) engine has a cylinder bore of 3.03" (77 mm), piston stroke of 2.83" (72 mm), and rated power of 25 hp (18.5 kW). The maximum forward and reverse speed - 16 mph (25.5 km/h). The open center hydraulic system includes a gear pump with rated fluid flow of 5.5 gpm (20.8 lpm).
The lift capacity is 700 lbs (318 kg) at 24" (610 mm) behind pin. The Case IH DX25E is equipped with a hydrostatic power steering, wet disc brakes, 7.00x14 (Std) or 25x8.50-14 (Industrial) front tyres, and 11.2x24 (Std) or 17.5Lx24 (Industrial) rear tyres. The tractor is compatible with Case IH LX110 loader with lift capacity to maximum height of 662 lbs (300 kg) and breakout force of 1361 lbs (617 kg).
