Tech update - skidders

John DeereJohn Deere

The John Deere L-Series skidders are said to offer best-in-class horsepower and an impressive power-to-weight ratio, maximizing productivity and increasing efficiency.

The recently updated L-Series skidders now feature more horsepower for increased pulling power and superior multi-functioning performance. The 648L, 748L, 848L and 948L models offer the highest horsepower for each size class, with the 300 hp 948L skidder boasting the highest horsepower on the market, says the company. The simplified engine after-treatment system allows for improved reliability and further reduces diesel fuel and DEF consumption.

The latest updates build upon the popular features from the initial L-Series launch, including a large, best-in-class cab with rotating seat and configurable joystick controls for increased operator productivity. The pressurized continuous-lube system axles, and Outboard Extreme axles on the larger models further improve uptime and durability. All L-Series machines come standard with five-year JDLink telematics in-base, better connecting owners to their machines, jobsites and their local John Deere dealer.

TimberPro TF840CTimberPro

TimberPro is all about versatility and delivering the best return on investment, says the company. The TF840C clam bunk skidder is no exception.

With 330 hp, dual-bogie axles, extra-large 32.4 sq ft clam bunk, TimberPro says that it is the ultimate skidder, hauling drags in excess of 20 tonnes. The company says that if there is a need to move a lot of wood over a long distance, the TF840C clam bunk skidder is the way to go.

With eight driving wheels, it offers superior flotation and maximum traction. The TF840C clam bunk carries the load over its rear axle, allowing it to skid uphill much more effectively than conventional grapple skidders. Along with the TF840C clam bunk’s stability and power comes an ability to be transformed from the ultimate skidder to the ultimate forwarder in as little as four hours by simply removing the clam bunk and bolting on a set of log bunks.

The TimberPro TF 840C clam bunk skidder fits the bill for contractors looking for a larger skidder, says the company.

Tigercat FPT N67Tigercat

Tigercat offers a full line-up of four-wheel and six-wheel drive skidders built for most full tree timber extraction applications worldwide. Tigercat skidders are powered by the fuel efficient and reliable Tigercat FPT N67.

The new 632E skidder is the most powerful four-wheel skidder ever built, says Tigercat. With a high horsepower engine, the 632E uses larger hydraulic pumps, valves and cylinders than previous models. It also features the Tigercat OB20 axle, delivering 47 per cent more torque capacity and nearly twice the life on all bearings. The 23 ft2 grapple is the largest grapple offered on any four-wheel skidder on the market, says the company.

The 635G six-wheel skidder builds on the improvements in the 632E with a new extreme duty Tigercat bolt-in bogie. The 635G excels in the toughest terrain and steep slopes, and the 25 ft2 grapple again leads the industry, says Tigercat.


Among the best all-terrain, all weather vehicles on the market today is the KMC track skidder, with its three unique features, says the company. These are: balance weight distribution, torsion bar sprung suspension, and high speed steel track.

The KMC track skidder has the ability to skid logs on steep slopes, sensitive soils or wet areas where it is not feasible to operate expensive shovel logging, cable yarding systems or conventional rubber-tired ground skidding equipment.

The KMC has the ability to skid logs on adverse 40 per cent gradient, favorable slopes to 50 per cent, and up to 55 per cent with site specific risk assessment of the operation.

The KMC can also skid areas of environmental concern with less soil compaction or site disturbance than any other ground skidding equipment, says the company.

The KMC tracked skidder is not designed to replace other ground-based skidding equipment—it is designed to be more effective when integrated with existing equipment. It will increase production while reducing the operating cost of existing equipment by working the areas those machines are not designed for, thus reducing wear and tear on the equipment.


Cat D Series wheel skidders enable loggers to operate more profitably by getting to the landing faster, increasing production, and reducing operating costs, says the company.

Cat D Series skidders feature a six-speed transmission with more gears in the working zone, lock-up torque converter and independent front and rear differentials for more pulling power and control, high-capacity cooling system and reversing fan, and high-performance hydraulics. The machines offer a roomy, quiet, and cool operator station and tilting cab for servicing. There are four models ranging from 203 hp to 275 hp.

Caterpillar recently introduced the High Rotation Seat cab and an enhanced monitor display for Cat D Series wheel skidders. The High Rotation Seat cab offers 100 degrees of seat rotation and features the new Cat Advanced Ride Management (Cat ARM) seat suspension for unparalleled ergonomics and comfort for the operator.

The Tanguay TG88E skidderTanguay

The Tanguay TG88E skidder is available as a clambunk or “L Boom” grapple configuration with a huge payload capacity of 35 tons.

Powered by a 400 hp engine, the eight wheel drive TG88E comes with a choice of track width up to 60” wide for low ground pressure. The reliable and proven 100 per cent hydrostatic drive provides incredible manoeuvrability and perfect traction for minimum ground disturbance, says the company.

Tanguay says that the TG88E clambunk and its powerful loader is the machine of choice to economically load and skid tree length to road side on long distances.

The “L Boom” grapple skidder has proven very productive on shorter distances and longer timber stands.

Designed and manufactured in Canada, the TG88E is by far the world’s largest forwarder and a solution for year round operations, says the company.


Awassos manufactures compact skidders for low impact operations. The company’s MD 80 skidder offers a modern design and superior capacity. With a reversible workstation, hydrostatic transmission, and a rugged cast iron chassis, Awassos says that it’s the ideal machine for big jobs without sacrificing the low-impact benefits to the environment.

Awassos strives to design and manufacture a line of forestry equipment that can handle challenging work situations, but are gentle in execution. It also offers additional options to equip its machines to accommodate various types of forestry work.

On the Cover:
Simple, clean and efficient were the guiding principles for B.C. logger Gregory Jacob when he began his examination of available steep slope log harvesting methods. He was able to get exactly that, and the key new machine in Gregory’s steep slope arsenal is a wheeled John Deere 1910E cut to length forwarder with a Haas winch. Read all about it on page 10 (Cover photo by Jim Stirling).

Spotlight - Finding your future employees
