engine with a rated power of 69 hp (51 kW), and single-speed or two-speed
hydrostatic transmission. The hydraulic system has a pump with a rated capacity
of 20 gal/min (79.6 l/min). The system pressure is 3050 psi (210 bar). The New
Holland L180 is equipped with 100 HD roller chains and 12x16.5 tires. The skid
steer loader has a lift height of 126.8" (3220 mm) to hinge pin and dump height
of 94.7" (2405 mm). The rated operating capacity is 2200 lbs (998 kg), and
tipping load is 4400 lbs (1995 kg).
