(3.32L) Yanmar 4TNV98CT-NMS 4-cylinder turbocharged diesel engine with a rated
power of 70.7 hp (52.7 kW), and 2-speed hydrostatic transmission. The hydraulic
system has a pump with a rated capacity of 23.5 gal/min (89.6 l/min) or 35
gal/min (132.6 l/min). The Mustang 3300V NXT2 is equipped with a vertical-lift
boom, 100H drive chains, and 14x17.5 HD tires. The skid steer loader has a max
lift height of 131.2" (3330 mm) to hinge pin and dump height of 98.5" (2500 mm).
The rated operating capacity is 3300 lbs (1497 kg), and tipping load is 6600 lbs
(2995 kg).
