EDIT - I've tried uploading lots of detailed photos yet they don't seem to be displaying. I've started a thread in the Landscaping section where the pictures display fine. 

I've owned both the drive unit and the 6 inch bit from new, and they've only had about 6 hours use maximum. They're to be sold together, not individually.

The bit is designed for use in ground like clay, and loam.

It's been used on a MultiOne, but I believe the mounting system is the same as Avant. 

This is supplied with standard hydraulic connectors only, NOT the multiconnector required to fit to MultiOne- you'll need to supply your own. If you already have one it's an easy 5 minute job to swap it off another implement onto this. 

Perfect, as new working order. Obviously has some visual wear from it's limited use.

Would advise collection in person from my yard, just outside Wroxham, Norfolk.

Or I'd be happy to deliver locally.

Price for both is £2000, no VAT. 

Happy to answer any questions- please get in touch if you have any.
