Tech Update- Tracked harvestersTimberpro


New for 2018 for Timberpro is the D series line of tracked bunchers and harvesters.

Improving upon the already impressive C series lineup, the D series incorporates many new features and updates. One of the major updates is a new larger operator cab. This new cab features panoramic views from the oversized windows, digital climate control and new seat options for the ultimate in comfort.

Also new is the Cummins L9 performance series engine. This Stage 5 engine goes beyond Tier 4 by simplifying the emissions system with a singe can SCR, allowing for a much cleaner installation and ease of serviceability. The L9 is incredibly powerful with increased torque, added efficiency and increased service intervals.

Other updates include new hydraulic cylinders, revised and beefed-up leveling system, new hydraulic pumps and new boom debris deflector.

Timberpro says that the new D series is the perfect balance of power, performance and productivity.

John Deere m seriesJohn Deere

The John Deere M series tracked feller bunchers and MH series tracked harvesters provide loggers with powerful machines designed to withstand tough conditions. The models are equipped with a Final Tier 4 engine, allowing machines to maintain peak engine performance while minimizing total fluid consumption.

The engines on the 800 and 900 models boast 300 hp and 330 hp respectively.

The tracked feller bunchers and harvesters feature spacious and comfortable operator stations. Ergonomically designed controls, adjustable armrests, fingertip control of machine functions and an air conditioned seat ensure operator comfort during long shifts. Additionally, the floor-to-ceiling and side windows along with the overhead skylight enhance the operator’s view of the timber.

The Rapid Cycle System, available for the M series and MH series machines, blends an automated felling head arm cycle with simple boom control. This system significantly reduces operator fatigue while simultaneously increasing efficiency and productivity.


Featuring numerous enhancements from the original design, Barko’s purpose-built 260B fixed and dangle head harvesters are said to offer exceptional productivity and efficiency.

The 260B is driven by a 225 hp Cummins QSB6.7 Tier 4 Final diesel engine with SCR aftertreatment. Offering a peak torque increase of 10 per cent from the previous model, the machine delivers superior productivity and fuel efficiency for reduced operating costs, says the company. It is also equipped with an extreme cooling engine package and a 36“ diameter auto-reversing fan that includes automatic temperature control.

The harvester features a wider D7A undercarriage with 8” chain pitch for added stability with larger attachments in the 60,000 lb class machine size. It delivers exceptional drawbar pull (1.13 to 1 ratio) and provides 65,481 ft/lbs of tractive effort. Ground clearance is 29”.

Dual swing motors provide continuous rotation and high swing torque of 50,787 ft/lbs. The machine features a heavy duty, oversized swing bearing and offers outstanding reach with any attachment. Boom plumbing has also been enhanced.


Caterpillar says that its track harvesters and feller bunchers feature the best combination of lift capacity, swing torque and tractive effort ratios to boost production. Purpose-built durability and low operating costs are said to increase profitability.

The Cat 541 and 552 Series 2 are full tail swing machines designed for high production clearcutting or final fell applications in rough environments. The Cat 521 and 522 B series are near-zero tail swing machines, which are more attractive for felling and bunching in select cut and thinning applications.

They are powered by the Cat C9 ACERT 303 hp engine, which boasts proven reliability and durability. The closed centre hydraulic system includes fully adjustable electric over hydraulic controls with two pumps for smoother multi-functioning. Large structures are designed for long life.

Caterpillar offers a leveling machine in each model series, and steep slope harvesting enhancements are available for the 552 Series 2.


Based on the popular Tigercat 855E feller buncher, the H855E and LH855E track harvesters are said to be highly efficient, durable and reliable carriers suited to a wide range of harvesting and processing applications. With the new three mode ER boom control, the operator can choose between ER, semi-ER and conventional. The new semi-ER function allows the operator to extend the boom on a horizontal plane using a single joystick, but retracts the boom with the increased power of both cylinders, doubling the pull force.

The durable design and construction starts with the Tigercat-built forest duty undercarriage and large diameter swing bearing. The upper assembly is built on a thick, one-piece turntable. All weldments are fabricated from high quality steel to resist impact. The LH855E FH400 leveling undercarriage has long track frames, a wide stance carbody and super duty leveling components, giving it superior stability, poise and operator comfort on steep slopes.

The combination of high horsepower and harvester head optimized hydraulics provide the operator with responsive control, quick feed speed and powerful delimbing capability for high performance and productivity, according to the company.


Again for 2018, Motion Machinery offers ELTEC tracked forestry machines with updates and improved features. This includes the new tilter options, log loaders, boom design, and more features to make the ELTEC products more operator friendly and serviceable for high uptime. ELTEC says it already surpasses the competition with such features as most visible and largest cabs, swing bearings, swing torque, and stability with extra-long track frames, so mounting that large processing head won’t be a problem with machine fatigue on an ELTEC. It offers some of the largest cooling and hydraulic flow on the market giving owners what they require for any head mounted on it. The company says that if loggers are looking for something new in feller bunchers, processors or log loaders, they should contact their ELTEC dealer.


Komatsu America Corp. recently previewed its new XT-5 series of track feller bunchers. Models include the XT430-5 (non-leveling), XT435L-5, XT445L-5 and XT465L-5, which replace the prior XT-3 series machines.

The XT-5 series ranges in operating weight from 66,359 lb. to 74,516 lb., and features a new, more powerful fuel-efficient EPA Tier 4 Final engine, gull-wing style engine hood, increased lift capacity, heavy-duty undercarriage, redesigned and relocated cab, new hydraulic and cooling systems, forestry-specific guarding and KOMTRAX telematics system technology.

The new 310 peak hp, Cummins QSL9 9-liter engine provides more horsepower, torque and displacement and lowers fuel consumption by as much as 10 per cent, due to advanced engine and hydraulic system control designs, says the company. Lift capacities at full reach lift have been increased by 77 per cent on the XT430-5, XT435L-5 and XT445L-5, and by 15 per cent on the XT465L-5. The XT465L-5 now readily operates the Quadco 24-inch cutting capacity disc saw heads.

The state-of-the-art, fully-certified, Komatsu forestry cab has been relocated to the left of the boom for industry commonality. Cab design changes provide superior lines-of-sight to each track. Standard rearview and optional right-side view monitoring systems further enhance the operator’s view. Eleven LED lights provide superior visibility for night operations.


Designed and built by A. Landry Fabrication Ltd in Balmoral, New Brunswick, the Landrich is the first purpose-built track harvester optimized for the cut-to-length method of mechanized logging. With the integration of state-of-the-art design, engineering and new capabilities, the Landrich has set a new standard in efficiency and performance, says the company.

The company says that customers can take advantage of the best fuel economy and productivity available on the market and an incredibly spacious cab designed for operator comfort and ergonomics. The Landrich is said to be a machine built for efficiency and profitability.
