Galaxy Tire & Wheel
The super traction E/L2+2 Giant Hippo tubeless tires from Galaxy Tire & Wheel feature twice the tread depth of a normal E-2 or L-2 tire and are built with mud breakers for self-cleaning action. Tread depths offer excellent traction, the company says, and measure 68/32nds on the 23.5x25 and 72/32nds on the 26.5x25. Buttressed shoulders provide 21 per cent more pulling power. Giant Hippo tires suit off-road material handling machines, articulating dump trucks and loaders in soggy ground conditions. The Beast, the super severe steel logger LS-2 tires from Galaxy, are constructed with steel cable from shoulder to shoulder and offer increased puncture resistance. Buttressed shoulders offer greater sidewall and shoulder protection, while the buttressed sidewall offers 21 per cent more pulling power in deep mud, the company says. Other features include a mud breaking, self-cleaning tread design and rim shield protectors that keep the edge of the wheel inside the tire, protecting it from damage. The Constellation Kevlar log skidder LS-2 tires are made with Dupont Kevlar, the same material used for bulletproof vests. Available in a full range of sizes, they offer a unique bar angle with superior self-cleaning action and traction in all conditions. www.galaxytire.com   Reader Service Card #372

Hultdins
ECO-Wheel Tracks from Hultdins protect tires and extend tire life, often reducing tire replacement by as much as one set a season, the company says. Tires are protected from excessive wear and have fewer flats in rough or rocky terrain. ECO-Wheel tracks last longer than chains and can eliminate the need for flotation tires or duals. The positive traction prevents slipping in soft or difficult conditions and the reduction in spin and grab means less stress on drive train components. The tracks are easy to install and adjust. All four tires can be outfitted in about one hour and periodic tightening is done as needed. The tracks also provide greater manoeuvrability and stability. Increased contact area lowers ground pressure for working effectively year round in swamps, mud, deep snow or rough ground. All track components are pressed or formed for reduced weight and maximum strength. The 500 brinell hardness offers wear resistance and long life compared to chains. www.hultdins.com Reader Service Card #373

Quadco
Bogie tracks from Quadco Equipment Inc are a unique track system offering durability and strength. Designed for heavier tired machines performing cut-to-length or tree length harvesting, the bogie tracks pads come in 4, 6 or 8 widths, depending on carrier weight class. Track models are available for most tires on the market, with pad sizes ranging from 30 to 54 to match ground conditions. More pads per track mean shorter, stronger links and less twisting or warping, as well as ensuring better wear throughout the life of the track. Pad steel has a high Rockwell rating for long life and heat treating results in more even wear characteristics. For most models, pads are banana shaped with corners cut to minimize ground and root damage. Maximum tire protection is achieved by aligning guide links and welded links, the company says. Limited drag design with the links close to the tires outside radius provides for a smoother ride. The bogie tracks are available in all-season and snow tracks. www.quadco.com  Reader Service Card #374

Trans-Gesco
Trans-Gesco manufacturers the large TG88C forwarder/skidder, designed for payloads of up to 35 tons and with 160,000 lbs of traction. The challenge to address the weakest link of its hydrostatic drive systemthe tireshas been met through a unique tire and track combination made specifically for the TG88C. Robust mining tires equipped with a thick sole are grooved and filled with permafill or RL solid rubber inserts. The tires effectively become a solid rubber sprocket wheel available in a wide choice of track widths, up to 60. The tracks are much larger than the tires, shielding them from the hazards of the forest. The overall result is a proven 100 per cent hydrostatic eight-wheel-drive traction with a tire and track combination offering extremely low ground pressure and high performance over extreme ground conditions, the company says. www.transgesco.com  Reader Service Card #375

Loegering Manufacturing
Steel and soft bottom skid steer tracks manufactured by Loegering Manufacturing Inc are fully adjustable and rebuildable and attach quickly and easily with a customized installation tool. After initial installation, the tracks can be reinstalled in under 30 minutes. With smooth running double-pivot design, the tracks extend tire life and are easy on the drive train, the company says. The steel tracks feature hammer-forged, wear-resistant steel pads with extra pad-to-ground contact for maximum flotation. Designed for less rutting and compaction, they can be custom fit to a specified model number. Loegerings non-marring, high performance skid steer soft bottom tracks provide superior flotation and traction and cover a significant amount of surface area. The tracks allow operators to work on finished surfaces without damage. The V-shaped, UV-stable urethane pads are self-cleaning and wear-resistant. Both tracks feature a new multiple-hole link design that provides numerous adjustment locations per track, fewer parts to maintain and less adjustment time. Durable, threaded Dura Pins feature easy replacement in the field and a foolproof design that allows the pins to be inserted only one way and locked in place. www.loegering.com  Reader Service Card #376

Bridgestone/Firestone
Firestone has introduced forestry tires to meet the challenges of the industry, adopting cut resistant tread construction (CRC) in its Forestry Special CRC line of tires. CRC provides a 12 per cent improvement in cut resistance and a 15 per cent improvement in wear. The new construction has been adopted for all its forestry tires including flotationlogger tires. In addition, Firestone has adopted Severe Service construction in two popular sizes, the 30.5L-32 18 ply and the 28L-26 16 ply. These tires feature nine per cent more body ply strength, 20 per cent more tread base rubber gauge and 20 per cent more sidewall gauge. The higher rating ply provides 10 per cent more load carrying capacity, compared to the Forestry Special CRC tires, the company says. Firestone is also introducing the 28L-26 and the 30.5L-32 in tubeless construction, meaning no wrestling with a tube during tire mounting, no pulled tube valves with tire/rim slip or low tire air pressure operation. Firestone continues to develop new wide Flotation Logger 23 DT tires to minimize the environmental impact of logging. The tires have a large footprint compared to conventional forestry tires, resulting in reduced ground disturbance and less soil compactiona plus for regeneration when new trees are planted. Firestone has 76x50.00-32 and 78x45.00-32 sizes, designed to work on the largest skidders in the industry, the company says. All Firestone forestry tires feature cut resistant sidewall and tread compounds, heavy tread and sidewall gauges and steel-belted construction. Metric forestry tires for harvesters and forwarders, as well as off-highway tires for wheel loaders are also available. www.FirestoneAg.com   Reader Service Card #378
