The
Case SR200 skid steer loader driveline system components: a 195 cu.in (3.2L)
Case 432T/M3 4-cylinder direct injection turbocharged diesel engine with a rated
power of 70 hp (52 kW), and 1-speed or 2-speed hydrostatic transmission. The
hydraulic system has a pump with a rated capacity of 22.5 gal/min (85 l/min) or
30.7 gal/min (116.2 l/min). The Case SR200 is equipped with a radial-lift
boom, ASA 100 drive chains, and 10x16.5 standard tires. The skid steer loader
has a maximum lift height of 123" (3125 mm) to hinge pin and dump height of
98.2" (2495 mm). The rated operating capacity is 2000 lbs (905 kg), and tipping
load is 4000 lbs (1815 kg).
