equipped with a two-speed hydrostatic transmission and steel-embedded rubber
tracks. The hydraulic system has a pump with fluid flow rate of 22.5 gpm (85.2
lpm). The hydraulic pressure is 3050 psi (210 bar). The compact track loader has
a rated operating capacity of 1890 lbs (860 kg) and tipping load of 5400 lbs
(2450 kg). The boom lifting force is 6080 lbs (2765 kg), and bucket breakout
force is 7270 lbs (3305 kg).
