Unused but sold AS-IS No Warranty.
This is a brand new Cat 305 excavator ripper attachment, offered at the lowest price available on eBay. The ripper is designed for Cat 305 CR, D, E, E2, 305.5E, and 305.5E2 models - specifically those with 45mm bucket pins rather than the early models that use 40mm pins.
The attachment also works with other mini excavator brands in the 40-65 size range that have compatible 45mm pin holes. It features 45mm pin holes (pins are not included with the purchase) and measures 6 1/8 inches between the mounting brackets, with pin holes spaced 10.25 inches center to center.
The ripper is completely unused but sold as-is with no warranty. Before purchasing, verify that your machine's stick and linkage measure 6 1/8 inches wide or less. If there is excess gap, 45mm shims are available separately on eBay. For machines using hydraulic or manual quick couplers, the center-to-center pin measurement needs to be nearly exact at 10.25 inches.
Contact the seller with any questions about fitment before committing to the purchase.
