Airknife system helps mill dust control
As showcased at the recent COFI conference in Kelowna, B.C. by a representative of West Fraser Timber, the innovative use of airknives manufactured by the B.C.-based Corbilt Group of Companies can be a critical part to the success of an overall complex dust pick-up system.
Corbilt has utilized the concept of small scale airknives, primarily used in the food industry, to form the basis for this design. The airknife agitates the dust from the larger partials at a high velocity towards the pick-up. This design makes up a critical part of the overall complex dust collection system and shows an 80 per cent reduction in dust at each drop point, says the company.

John Deere improves fuel economy on forestry swing machines
John Deere says it is committed to providing customers with improvements that make both the machine and operator more efficient—and one way of doing that is by improving the fuel economy on forestry swing machines with an updated pump/management system and fuel economy kit for existing models.
When operating in high-power mode, these upgraded machines showed a marked improvement in fuel economy without loss in productivity, which translates to gains for the logger’s bottom line.
“With fuel prices on the rise, running a fuel-efficient operation is now more important than ever for loggers,” says Dave McFarlane, product marketing manager, John Deere Construction & Forestry. “The enhancements to our fleet of swing machines are a testament to John Deere’s dedicated focus to provide powerful equipment that gets the job done in the most efficient manner possible.”
Swing machine enhancements will be implemented on all models, including the 2154D, 2454D, 2954D and 3754D. Fuel economy kits are also available to update existing machines manufactured prior to November 15, 2013.
Cat site prep tractor powers high flow attachments
The new Cat 586C site prep tractor is a multi-purpose, heavy-duty machine with the muscle to run power-hungry mulchers and brushcutters.
“The tractor runs cool and doesn’t collect debris, so you’ll spend less time cleaning and more time working,” says Matt McDonald, Caterpillar Forest Products product specialist. “Plus, you can tackle a variety of projects with one machine, lowering your owning and operating costs.”
New Cat work tools have been developed to match the powerful capability of the 586C. The Cat HM825 mulcher and the Cat BR624 brushcutter will be available from the factory and supported by Cat dealers. Other attachments, such as buckets and rakes, are offered by Cat dealers.
The PowerDirect Plus system on the site prep tractor optimizes performance by monitoring operator and attachment hydraulic demand and delivering power where and when it is needed. The 350 hp engine and oversized hydraulic system push more flow to the attachment for faster recovery, without slowing other functions.

The 28” bar weighs in at about 500 grams, the 32” bar weighs about 600 grams, and the 34” bar weighs about 700 grams.
Kenworth makes Bendix front air disc brakes standard on Class 8 trucks
Kenworth Truck Company will make Bendix ADB22X front air disc brakes standard on Kenworth Class 8 tractors and trucks.
The Bendix ADB22X air disc brakes have a two-pin floating caliper design that provides a more stringent overall dimension accuracy and consistent force distribution. According to Bendix, the ADB22X design also significantly reduces brake fade with no degradation of stopping power. Bendix recently marked the production of its 500,000th ADB22X air disc brake.
“We’ve offered Bendix air disc brakes as an option on our Class 8 trucks previously. Customers appreciate their superior performance, car-like feel, ease of maintenance, and lightweight design, while they also exceed the U.S. government’s RSD (reduced stopping distance) requirements,” says Kurt Swihart, Kenworth marketing director. “These benefits are so compelling that Kenworth decided to make air disc brakes standard on Kenworth Class 8 trucks.” For additional weight savings, the air disc brakes also come standard with an aluminum hub and splined disc rotor assembly.
New ARGO product enhancements help workers get more done
In response to market demand, Argo has extended its capabilities in the commercial sector with the introduction of the 8x8 XTD diesel-powered Argo, a load-tested universal mounting system (UMS), a utility box, an eight-wheel trailer, a heavy duty track system and a variety of factory-approved tools for specific industries.
Created with the same high engineering standards that have made Argo world-renowned for quality and durability, an 8x8 XT model is now available with a Kohler Lombardini diesel engine. The XTD will now share the same fuel as other machines on the work site, eliminating the need to haul in gasoline. Its three-cylinder, 24 hp, 1028 cc engine provides optimal power at higher rpm’s, making it an ideal choice for the heaviest duty cycle industrial applications.
Similar to the gas-powered 8x8 XTI model, the XTD features a towing capacity of 2000 lbs. and payload capacity of 1340 lbs. The direct drive triple-differential Admiral transmission delivers torque to all eight tires for virtually unstoppable power on even the roughest terrains, according to the company. The 25” tires with Argo’s unique tread provide optimum traction on land and propulsion in water.
Peterson introduces 5710D horizontal grinder
The all-new 5710D horizontal grinder is the latest design of high production grinders by Peterson.
Powered by a Tier IVi Caterpillar C27 engine generating1050 hp, the 5710D is said to have the power to handle the toughest jobs.
At 88,500 pounds the 5710D was designed for operations that require frequent moves between jobs without a special permit. An optional transportation dolly allows the Peterson 5710D to be easily moved, and then set-up for operation within minutes.
With a feed opening of 60 x 40 inches combined with Peterson’s high lift feed roll, the 5710D can readily reduce a wide range of material including stumps.
The 5710D utilizes Peterson’s Impact Release System that can be set in the detent mode to provide consistent product sizing or switched to the floating anvil mode for a primary reduction where accurate sizing is less critical. The floating anvil mode provides high production primary reduction with more protection from contaminated feedstocks, and reduced fuel consumption.
The 5710D’s new generation of controls includes Peterson’s high production Adaptive Control System and a fully adjustable feed system that can be optimized for a wide range of materials.
The 5710D features a large grate area that enables the 5710D to produce materials to exact specifications. A quick-change multiple grate system makes it easy to customize grate configurations to produce a wide variety of finished materials. Grates are removed through an enlarged access door on the side wall of the 5710D.
Another major innovation included on the 5710D is Peterson’s Impact Cushion System. Urethane cushions allow movement of the compression roll/anvil housing pivot shaft, cushioning impacts due to contaminants in the feed material. Shear pins above the cushion and a sensing circuit that stop the engine help protect the shaft from catastrophic damage in the event of a severe impact.
New Tigercat loader grapple
Tigercat has released a new grapple design to complement the LG4053, which has been equipped on Tigercat knuckleboom loaders for many years. The new LG5057T has a 5” close or minimum opening and a 57” maximum opening, as well as an all-new tapered tong profile.
The grapple was conceived and developed to improve loader performance and productivity in sorting applications. In first and second thinning operations, there are often many types of logs that must be merchandized and sorted, ranging from pulpwood to super pulp to chip ‘n saw logs.
The most noticeable feature of the LG5057T grapple is the tapered tongs. The narrow grapple tong tips significantly improve the ability to efficiently and quickly pick logs out of a pile. The new arm profile is also more rounded at the tips, allowing the logs to roll up into the grapple easily. This increases the holding capacity of the grapple when gathering numerous smaller diameter logs.
The LG5057T is equipped with cylinder guards to protect the rods from truck stakes and other hazards that could scratch or bend the cylinder rods. The rotator assembly is the same as the current LG4053.
