New large tree processor spins 360 degrees
Feb. 13, 2017 - The new Keto 873 processor is designed for processing larger trees in the demanding conditions of North America and beyond. Keto 873 is the latest model of the Keto product family. This 3360kg/7400lb head can be installed on 30+ ton tracked base machines. Kone-Ketonen and Quadco Equipment Inc will introduce the Keto 873 in the 79th Annual Oregon Logging Conference in Eugene, between Feb. 23rd to 25th, 2017.
Keto 873 was created based on the vision of CEO Lauri Ketonen, designed and produced by the engineering team lead by designer Mika Myllyniemi, and utilizes the best proven components available today.
One new feature of the Keto 873 is the Rotobec rotator, which spins 360 degrees and beyond. This offers a totally new world of freedom and efficiency to operators.
The Keto 873 design incorporates a well-proven Parker valve system. Functions are proportional and operate only on-demand, which are key factors in optimizing the fuel consumption of the base machine and running the system at the lowest possible temperature.
Track feed motors are made by Danfoss like in other Keto models. The 500cc motors produce a level of nearly 4kN of true net pulling power making sure that even the toughest trees can be pulled and delimbed quickly and efficiently.
Like in any Keto head the length measuring is done by the two feeding tracks. It is simple, extremely reliable and low cost to maintain. A larger front knife cylinder together with the bottom arm cylinder provides the needed holding power when pulling big trees from the deck. The geometries of the three moving and one fixed knives and arms have been optimized to handle the full range of diameters. Another very important feature in the Keto 873 is the shortest possible tilt frame with a very wide working angle. The short tilt minimizes the unwanted head sway caused by the boom movement, thus making the head easier to control.
Kone-Ketonen Oy was founded 1984. For over 30 years it has been producing numerous models of harvesting heads for thinning and larger heads for clear-cutting and processing. About 5,000 heads have been produced so far. Kone-Ketonen exports about 80 per cent of its products to Europe, Japan, South and North-America.
