transmission, vertical-lift loader boom, dozer-style undercarriage, and 17.7"
(450 mm) rubber tracks with steel inserts. The hydraulic system has a pump with
fluid flow rate of 24.2 gpm (91.5 lpm). The hydraulic pressure is 3050 psi (210
bar). The track loader has a rated operating capacity of 2590 lbs (1178 kg) and
tipping load of 7400 lbs (3364 kg). The lift height is 131.6"" (3340 mm) to
hinge pin, and dump height is 105.1" (2670 mm).
