Heavier Hydraulic Cylinder Walls
The thickness of the backhoe swing and bucket cylinder walls has been increased 33 percent from 3/16 inch (4.8 mm) to 1/4 inch (6.4 mm), for greater strength.

New Backhoe Control Valve
The 580K features a Case-built backhoe valve with all backhoe sections combined into one integral valve bank. This results in:
□ Fewer external hydraulic connections and less plumbing.
□ Reduced potential for leaks.
