The new Timberjack FD45 disc saw felling head is a high accumulation disc saw felling head designed specifically like the Timberjack 740 wheeled buncher, operating primarily in first and second thinning applications. The FD45 features Best-In-Class size with a 990 sq. in accumulation, offset pocket for gathering multiple small stems. With capacity to cut and hold single stems up to 20 inches in diameter, the FD45 lest the operator choose which trees to remove on the go. The head can accumulate 10-15 stems in the 8 12 diameter range. The FD45 weighs in at 4,900 pounds. It has a 53-inch diameter Series 4000 blade with harrow kerf design. The twin post design provides maximum visibility to the cutting zone. All lubrication points are accessible from the side of the head Hard to reach lubrication points are equipped with grease lines to allow remote access.

Todays logger must consider many different criteria before in a harvester. Harsh forestry conditions require equipment with various applications and with high productivity. The caterpillar harvester line includes models designed and built to be used in various applications from first thinning to final felling and that are able to handle trees of different diametres.
The Caterpillar Harvester line has been engineered specifically to address operator comfort. All cabs have a roomy interior easy-to-reach controls and a suspension design that sliminates vibration.

Easy-to-reach controls give the operator full finger tip command. The harvesting head and boom and stick functions, plus the cab rotation are controlled from these levers.
Boom and stick consist of a two-section stick with a box construction design that extends 2,5 meters. Boom incorporates dual hoist cylinders, stick cylinder and extension cylinder. The boom and stick swings with the cab and is mounted along the side of the cab.

The operator may also adjust the pendulum arms to level the machine while harvesting. The pendulum arm suspension technology has revolutionized the industry. With this kind of versatility the operator can access trees in the tightest of thinning areas and toughest of sloping conditions.
Machine movement is controlled by floor peduls to free up the operators hands to maneuver the harvesting head with the boom and stick.
Excellent viewing area gives the operator a direct view of the harvesting head and the tree. The boom is mounted beside the cab, rather than directly in front. Windows are made of polycarbonate material to promoter maximum protection for the operator.
Directional travelling is controlled by a floor pedul for easy changing of forward and reverse.
Operator ergonomics are improved through an eight-way adjustable seat, with seven-way adjustable armrests.
The computer aided bucking and measuring system is located in direct line-of-sight for easy viewing. A digital monitoring system displays all vital machine information and alerts the operator of potential hazards that could damage the harvester.

The SMV Rapid EGS is a harvester for exacting jobs, with all the attributes characteristic of a powerful single-grip harvester. The machine is equipped with a strong loader and stable chassis, which makes it excellent for handling trees in large-scale final felling. The basic model has 6 wheels, but will naturally gain greater stability as an 8-wheel model. The short, compact wagon chassis with double articulated frame locks forms an ideal base for RK 200 harvester loader, with has a very high lifting capacity.

With a stand-operating harvester, thinning is evenly distributed over the entire thinning area, and the strip road distance can be increased to just over 30 meters without additional manual felling. The Rottne 2004, stand-operating harvester, is narrow, compact, light-footed and flexible and a unique pendelum-arm system that provides first-class terrain capability. Thanks to the leveling feature it is always possible to retain the machine width even in stony and very hilly terrain.
There is a great need for brush cleaning in young forest stands and that is mostly done manually with a powered brush-saw. There are no machines special built to do the brush cleaning mechanically, but the stand operating harvester Rottne 2004 can easily be changed to a cleaning machine. A cleaning head, a mounting kit and 4 big wheels are what is needed to convert the machine to a very efficient brush cleaner.
The Rottne 5005 is a highly efficient machine for both thinning and final felling. This harvester is compact, flexible and easy to manoeuvre, and also has a strong loader with excellent reach. Rottne 5005 has unique pendulum-arm system, and its advenced leveling function enables the machine to cope with very difficult terrain. This machine is easy to operate.
Rottne H-20 is primarily designed for final felling and large sized trees, but as it is versatile and easy to operate it can very well be used as a strip road operating harvester in later thinning. The powerful loader RK 200 and the unique design of the head EGS 700 with five feed rollers keep the trunks in a firm grip which is a benefit for delimbing and the measurement accuracy.

The Cat 527, 515 and 525 Skidders can easily handle a variety of tasks and applications for todays loggers Maximum skidding performance is best attained through the available swing boom and grapple. This tool is ideal for locations with soft terrain. High horsepower and torque enhance the 527s dozing abilities. The blade offers high levels of versatility in dozing and decking applications Expanded track options allow the 527 to maintain skidding performance and minimize ground disturbance. Superior balance and pulling power enable the 527 to skid large loads with the optional 527 winch. This highly productive winch has been specifically designed for the 527 skidder in steep and mountainous skidding applications.

Excellent skidder balance, plus the powerful mechanically driven, heavy duty skidding winch provides outstanding 515 and 525 cable skidding performance. Expanded tire options allow the 515 and 525 to maintain skidding performance in a wide range of ground conditions. The 525 is available with swing boom and grapple. With excellent balance and outstanding visibility, the 525 with swing boom is an ideal tool for very rough or soft terrain, thinnings, and select cuts. The 525 has the horse power and wheelbase to handle dual function arch and large capacity bunching grapples.
Load sensing Hydraulic system improves skidding performance and efficiency. Load Sensing hydraulics utilize a load sensing variable displacement pump and pressure compensating system, which continually monitors braking, steering, and grapple hydraulic power requirements. The Auto-Grab feature from Cat constantly monitors and adjusts tong pressure as needed to securely hold grapple loads while skidding.
