My folks have a NZ made Hansa chipper - http://www.hansaproducts.co.nz/
.. If you want photos and measurements, let me know and I will get info
when I am at the farm next/
IIRC it has a 13hp B&S motor. As I recall it as not cheap, but will eat
trees, the bodies of door-to-door salesmen and anything else that gets
put in the slot.
