Like all such heads, the 660C comes with a topping saw, this one a 16.5-in model. Also like all Keto heads, this one relies on the dual track feed system that makes Keto heads unique, applying the full 8000 lbf of delimbing force to the job at hand.
Ketos are perfect for both in-the-woods harvesting and on-landing applications, where the longest log lengths must be measured with a very high accuracy.
