The Case International 3230 is a 3200-series utility tractor. This model was manufactured from 1994 to 1997. The IH 3230 tractor is powered by Case D206 four-cylinder liquid-cooled diesel engine with operating power of 56.1 Hp (41.8 kw) and 220 Nm (163.2 lb-ft) of max torque at 1400 rpm.

The Case IH 3230 is fitted with two types of transmission. Type 1: 8x4 synchromesh transmission. Type 2: partial powershift transmission with 16 forward and 8 reverse gears. The maximum travel speed is 15.7mph / 25.2 km/h (forward) and 4.8 mph / 7.9 km/h (reverse).

The open center hydraulic system includes a gear pump with fluid flow rate of 15,6 gpm (59 lpm). The main relief pressure is 175 bar (2500 psi). The two-wheel drive tractors are equipped with 7.50x16 front tyres and 16.9x28 rear tyres. The 8.3x24 front tyres and 23.1x34 rear tyres fit four-wheel drive models. The wheelbase is 84.5 inches (2140 mm) for 2WD (4x2) models and 88 inches (2230 mm) for 4WD (4x4) models.
