Woe betide any Appalachian tiger swallowtails who get caught up in this ungodly four-foot flailhead. Moving to higher ground won't save them either, because Robocut's 40hp Isuzu diesel engine and high grip tracks can chew up 55-degree slopes without ever pausing to contemplate. The bargain price? £40,000 ($60,000) plus extra for antihistamines. Apocalyptic video after the break.
