It's to mount my Scheisling front mount chipper to.
I've got a Vermeer 625AI on tracks which is fine, however i had a few jobs last year when chipper on the unimog would be better, especially as some theiving scumbag nicked my best army shovel off the mog when it was parked up in the wood 100yrds from where we were working with the chipper.
I will post you for your contact details thanks. Ed
