Where to buy

When you're out in the woods, running back to the shop for a different piece of equipment isn’t always an option. So you want to make sure what you’ve got is up to the job — it's one of the things that makes the Waratah HTH618C so attractive.

Building on the versatility, efficiency, and durability of the HTH616C, the HTH618C adds double bottom knives for increased stem coverage, resulting in improved delimbing or debarking quality (depending on the configuration). Even with additional knives and topping saw, the HTH618C retains a short, robust chassis that can easily be positioned in tight spots while selective thinning or taking on the bent and ugly timber for which this series is famous.
