Gehl 3310 skid steer loader is powered by 47.7 cubic inches (0.8L) Onan B48G
2-cylinder 4-valve air-cooled gasoline engine with a rated power of 20 hp (14.9
kW) at 3500 rpm. The Gehl 3310 is equipped with a radial-lift loader boom,
single-speed hydrostatic transmission, 60H drive chains, and 5.70x15 (Std) or
27x8.50x15 (Opt) tires. The hydraulic system has a pump with fluid flow rate of
11 gpm (42 lpm). The hydraulic pressure is 2200 psi (152 bar). The skid steer
loader has a rated operating capacity of 750 lbs (340 kg) and tipping load of
1500 lbs (680 kg). The lift height is 102" (2590 mm) to hinge pin, and dump
reach at full height is 15.5" (395 mm).
