Case 580K Backhoe Specifications

Newly Designed Over-Center Lock

The 580K backhoe continues with the over-center design and is held in the over-center position by a large heavy-duty, cast-ductile-iron lock. The operator releases the lock from the seat with a foot pedal. If unit is equipped with optional tilting backhoe control console, then the backhoe is released from the over-center position with a hand lever.

Over-Center Snubber in Boom Cylinder

A snubber in the boom cylinder and a rubber bumper cushion the shock loads when the backhoe is returned to the over-center position. The snubber slows the backhoe when it comes over center, preventing ajar or bounce.

Newly Designed 14'8" (4.47 m) to 18'2" (5.54 m) Extendahoe

The 580K features an all-new Extendahoe formed from fabricated steel. The Extendahoe housing slides completely over the dipperstick. Benefits include:

□ Fewer moving parts to wear.

□ No lubrication required.

□ Replaceable synthetic wear strips on all four sides.

Replaceable Extendahoe* Wear Strips

For improved serviceability, the Extendahoe features replaceable wear strips retained by bolts. These wear strips can be shimmed to keep the Extendahoe housing-to-dipperstick tolerances tight for improved life and wear.
