The Hansa C27 appears similar to the Vermeer BC625 and the 6" Rayco and the like
I think the Vermeer was the first around in disk chippers , and others have used pretty well the same concept/similar design.
Couple of nice features in the Hansa C27 video ....
1. the adjustable knife blades rather than having to adjust the anvil .... should be simpler when knives are changed. Hopefully having the knife bolts go through a slot still holds the knives securely.
2. the whole chipper assembly on a turntable seems nice so you can position feed tray in a safe/convenient direction.
Problem may be durability of this as there is lot of vibration transmitted to chassis and have noticed on my (its an old well used vermeer) that the chipper housing to trailer welds is one of the metal fatigue points.
In any case watch the 'throat size' .. those with a rectangular throat are more forgiving when feeding material with branches (at the fork point).
its a fair investment at $27k, but if you keep an eye open, have seen similar (vermeer, rayco etc) machines in good order going on gumtree and facebook around the $10k mark. They should have plenty life left in them for non professional use -- that is not full time tree lopping where machine is going all dsy every day. Often seller is eanting to upgrade to a bigger machine.
In any case, under the current deprecistion tax rules, if its costs under $20k, its 100% tax deduction in year of purchase.
Here is example of one currently on Facebook marketplace.
