The new model Log Max 6000V has finally arrived to North America. With over 20 updates, the 6000V is sure to make the logger’s life easier and more enjoyable through production efficiencies and increased uptime. Changes include an updated measuring wheel system and an improved hydraulic circuit. As well, the 318 True Cut system is the smartest and fastest auto-tensioning saw unit offered on the 6000V. The unit can also be delivered with a manual saw tensioner if desired. Replaceable pins for the felling link cylinder are now standard equipment.

Ponsse heads are widely used in track and rubber-tired harvesters in Canada. Ponsse has designed heavy-duty (HD) versions of the H8 and H7 especially for Canadian logging operations. HD is designed for the hard use in tracked machines, featuring a reinforced frame and tilt arm. Strong grip, powerful feeding and fast sawing are packed in a robust and reliable package. The Ponsse Opti-control system designed for Ponsse heads gives more cubic metre per hectare. With Ponsse heads you burn less fuel and produce more.

Pierce Pacific
The revolutionary forestry tool that changed the industry is changing it again. The new Pierce GP ProSeries offers extreme durability, superior log quality and unmatched loading efficiency. It’s the only one of its kind that shovels, sorts and loads like a grapple, and delimbs, measures and cuts like a processor. From more precise measuring with its new measuring wheel design to the advanced control technology of the new Forester Control System, the GP ProSeries arrives with several significant upgrades.

John Deere
The John Deere H413 and H415 harvesting heads offer a solution for a variety of logging operations. The H413 was designed to carry out a range of jobs, optimizing delimbing coverage and quality. When paired with multi-tree-handling equipment, the H413’s powerful saw unit masters fast and precise felling and crosscutting. Boasting strength and stamina for large timber, the H415 combines large timber cutting power with excellent delimbing quality, offering unprecedented tree-processing performance. Feeding is effective with the H415 due to the location of the delimbing knives and its strong grip and trunk handling features.

AFM Forest
The AFM 65 is a strong, reliable and highly productive harvesting head especially made for hardwood operations. The AFM 65 is an efficient tool for clearcuttings, big thinnings and processing operations. Four movable knives on the AFM 65 allow for smooth and accurate delimbing of even big trees with heavy branches. The stem is constantly centered in the head with four feeding rollers ensuring precise length and diameter measuring. Proportional adjustments of pressures on rollers and knives according to the stem diameter considerably increase the effectiveness of feeding and delimbing. The AFM 65 can work with a variety of measuring systems and is perfectly suited for 20- to 25-tonne excavators, wheeled and tracked harvesters.

Pro Pac
Pro Pac offers three felling head models: the 22R, 24R and 22X. All three are fitted with a Rexroth variable displacement saw motor, a reinforced tooth holder one-piece saw blade, and one hydraulic cylinder per grab arm. This gives it an excellent grip on large diameter trees. The 22X from Pro Pac is equipped with excavator teeth on its rear skirt, which facilitates climbing steep slopes, carrying out light excavation works such as developing skidding trails, digging trenches to prevent soil erosion and repairing ruts caused by skidders or forwarders, without sacrificing the performance of its felling function.

Kesla has the market’s most extensive range of harvester heads, covering all CTL logging from thinnings to final fellings. The recently renewed series of L-segment heads weighing from 1,300 to 1,800 kilograms contains suitable models for heavy rubber wheelers (the 27RH-II and 28RH-II) as well as for tracked harvesters and excavators (the 29RH-II and 30RH-II). The maximum cutting capacity is 780 millimeters and the max delimbing force is up to 8,100 pounds. The 28RH-II and 30RH-II with four knives are optionally driven by two or four feeding motors, while the 27RH-II and 29RH-II with three knives feature two feed motors.
