New Prentice loader improves efficiency
A new Prentice B Series Knuckleboom log loader recently launched by Cat Forest Products provides loggers with the best of both worlds – high production levels and low fuel consumption. The 2384 B achieves this through an enhanced engine and hydraulic power system, a choice of three operating modes, and an automatic idle down system.
More efficient use of horsepower to cut fuel consumption and maintain production is achieved through reduced engine and fan speeds, a reengineered hydraulic pump and bigger hydraulic lines. Loader performance is further improved by a 15% increase in swing torque and modified main control valve spools that improve cycling to lower the boom faster. The faster grapple action is achieved through the increase in the hydraulic line size.
The three operating modes include the Run Mode for normal applications, the Power Boost Mode with a 40% increase in productivity muscle for heavy duty delimbing, and new to the B Series of machines, the Intermediate Mode, which provides the operator with an option that fits between Run and Power Boost.
Other major features on the machine include: the Auto Idle Down, which conserves fuel by providing full power only as required; a diagnostic screen on the console that gives data on many of the machine’s vital signs; a new heating and air conditioning system; and lower noise levels in the cab. www.prenticeforestry.com
Bracke trencher offers improved efficiency
The world’s first four-row disc trencher is about to hit the market. The T26 twin from Sweden-based Bracke Forest is scheduled to be released this spring. The company says it is the world’s largest and most productive disc trencher for use in the forestry industry.
The new machine has the capability of reaching a production rate of 2.8 hectares per hour, which is an increase of more than 80% over the company’s two-row model. The added production results in lower fuel consumption and wage costs per hectare.
The T26 Twin has been developed for the company’s markets where large forwarders are used, including the Nordic region and North America. www.brackeforest.com
John Deere skidder updates
John Deere has announced updates to its skidder product line with a new lock-up torque converter option for the 640H and 648H skidders and a standard brake declutch on all of its direct drive skidders.
The company says the lock-up torque converter will provide skidder operators with “a significant increase in productivity in the woods” when compared to a standard torque converter. Deere’s lock-up converter stays locked during shifting and through a wider range of ground speeds, which according to the company, keeps the machine momentum through shifts and helps to ensure a smoother ride. In a productivity comparison, John Deere says a 648H skidder with the lock-up option moved 24.4 per cent more tons per hour under maximum load than a unit equipped with a standard torque converter.
The brake declutch feature, which was previously standard on all John Deere torque converter and lock-up torque converter skidders, is now standard on direct drive skidder models 540G-III, 548G-III, 640H, 648H and 748H. The change makes the skidders easier to operate,improving productivity as with the flip of a switch, the operator no longer has to work the clutch pedal or the Forward-Neutral-Reverse shifter when using the grapple. www.deere.com

The new models are available in a number of configurations, including rubber tired and crawler models, and a pedestal mounted machine or an electrically-driven machine. Both the 835 and 840 D Series models feature the 264 HP Cummins diesel engine.

Best dressed loggers?
What are the best dressed loggers wearing this year? It could be functional Valmet-brand clothing. The company has offered clothing for some time, but they say their “new line of cool, high quality clothing for work or play will provide customers with a sense of pride in being part of the Valmet family.”
The design work for Valmet’s newest winter collection was outsourced to a specialist clothing company where the designers produced unique garments for Valmet, all with a common colour scheme. This new range is a winter collection, but Valmet says they hope to broaden the range about twice a year. The clothing is available from your local Valmet dealer, or at the Valmet on line store. www.komatsuforest.com
