Prentice Boosts Skidder HP; Fuel Economy Same

            Prentice has increased horsepower on skidders, reducing cycle times and boosting productivity with no increase in fuel cost per ton.

            Increasing horsepower from 173 hp to 190 hp has resulted in a 6.8% improvement in cycle times, 7% increase in drawbar pull and an average 8.5% increase in load start-up torque. These improvements will result in higher production, according to Prentice.

            For example, if a logger produced 50 loads of wood per week, the 190 hp Prentice skidder would add more than three additional loads or 88 tons. At $40 per ton, the extra loads would generate over $3,500 in added revenue per week with no increase in work hours and no increase in fuel cost per ton.

            The new Prentice continuous rotation grapple improves production, too. The curvature of the tongs rolls the wood better and makes loading easier, and clamp force and the raised edge increase the grapple’s grip on a load, preventing slippage.

            The new Prentice grapple is lighter but stronger. Features that contribute to the improved durability include box section structure, baffle plates inside tongs and wear-resistant cast tips. The large capacity hydraulic flow-divider valve also is designed for durability. Several grapple sizes are available.
