Case IH 585 Troubleshooting

The Case IH 585 utility tractor was manufactured between 1985 and 1990. The Case IH 585 tractor is powered by 206 cu.in (3.4 L) Case D-206 4-cycle 4-cylinder liquid-cooled diesel engine with a rated power of 60 hp (44.7 kW).

The Case IH 585 is fitted with a two transmission options: synchromesh transmission with 16 forward and 8 reverse gears, or partial powershift transmission with 16 forward and 8 reverse gears. The maximum travel speed (forward/reverse): 15.6 mph (25 km/h) and 4.9 mph (7.9 km/h). The open center hydraulic system has a gear pump with a rated capacity of 15.1 gpm (57.2 lpm).

The lift capacity is 3210 lbs (1460 kg) at 24" (610 mm) behind pin. The 2WD models are equipped with 7.50x16 front tires and 16.9x30 rear tires. The 7.50x18 front tires and 13.6x38 rear tires are used for 4WD tractors. The wheelbase is 78 inches (1980 mm).
