Overview & condition
This Keystone Pounder KP-55 in Christiana, Pennsylvania, is offered as a skid-steer post-driver package with an auger setup included. The listing describes universal quick-attach mounting and auxiliary hydraulic operation, providing both driving and pilot-hole drilling capability. Asking price has dropped from $12,500 to $11,500.
The seller represents the package as ready for work, but no specific recent repairs, rebuilds or component replacements were supplied. Auger dimensions and the exact included components have not been itemized. The carrier's hydraulic flow, pressure, couplers and mounting compatibility need to match the attachment. The original narrative speculated about past ownership and use; a firsthand ownership history was not established.
