Caterpillar 259D3 Specifications
The
Caterpillar 259D3 compact track loader is powered by 203.1 cu.in (3.3L) Cat
C3.3B DIT 4-cylinder turbocharged diesel engine with a rated power of 73.2 hp
(54.6 kW). The Caterpillar 259D3 is equipped with a 2-speed
hydro transmission, vertical-lift loader boom, fully suspension
undercarriage, and 12.6" (320 mm) or 15.7" (400 mm) rubber tracks. The hydraulic
system has a pump with fluid flow rate of 20 gpm (76 lpm) or 30 gpm (112 lpm).
The hydraulic pressure is 3335 psi (230 bar). The loader has a rated operating
capacity of 2010 lbs (915 kg) and tipping load of 5740 lbs (2610 kg). The lift
height is 121" (3.08 m) to hinge pin, and dump height is 89.9" (2.29 m).
