Completely New Backhoe Design
The 580K features a totally new backhoe from the main frame to the bucket, for increased strength, performance, serviceability and visibility.
For better strength to hold up under the toughest conditions, the swing tower, boom, dipper and stabilizer legs are made entirely from a proven, durable, cast ductile iron. (Previous Case backhoes and all competitors use fabricated steel.) The cast iron adds to backhoe strength because of:
□ No welds, for constant strength throughout the structures.
□ It has 62,000 psi (427 474 kPa) of tensile strength compared to 50,000 psi (344 738 kPa) for fabricated steel.
The new backhoe is still an over-center design for stability, shorter transport length and improved backhoe bucket to ground clearance. The boom, dipper and bucket each has a single cylinder for improved visibility into the trench.
