I have what Bobcat calls an "interface adapter" for changing the augerhead from your skid steer plate to mount it on an excavator with the "exchange system". I used it for a Bobcat 15C auger on a 430 excavator. I upgraded myself to a Kubota excavator and have no use for this anymore. I'll try to post picture later, but anyone with this type of equipment knows what it is. I paid around $400 and only used it two or three times. This is for the adapter only, no powerhead or bits. Please call 814- if you have any questions.
