John Deere 5575 Troubleshooting
The
John Deere 5575 skid steer loader driveline system components: Yanmar 3TNE88
three-cylinder liquid-cooled diesel engine with a rated power of 36.6 hp (27.3
kW), and single-speed hydrostatic transmission. The hydraulic system has a pump
with a rated capacity of 11 gal/min (42 l/min). The system relief pressure is
2750 psi (190 bar). The John Deere 5575 is equipped with a vertical-lift loader
boom, heavy-duty drive chains, and 10x16.5 or 27x8.5-15 tires. The skid steer
loader has a maximum lift height of 111" (2820 mm) to hinge pin and dump height
of 87.9" (2235 mm). The rated operating capacity is 1410 lbs (640 kg), and
tipping load is 2850 lbs (1290 kg).
