Largest Terex CTLs flex their muscles
Without a boost in engine horsepower, Terex claims doubledigit gains in tractive effort, bucket breakout force and implement pressure for its largest compact track loader models. As outlined in a June 18 web conference, the PT-100G and PT100G Forestry models retain the class-high 99.9 horsepower of the original PT-100 and PT-100 Forestry units, but use a 47-percent more powerful implement pump to help increase horsepower to the attachment by a claimed 32 percent. When the machines are in low gear, a 14.6-percent increase in tractive effort translates into more pushing power. Write 55 on Reader Service Card. - Mike Anderson

Tires for rocky terrain
The new Michelin X-Traction tire from Michelin Earthmover Tires is designed for earthmover transport equipment operating in rocky terrain. The tire became available in North America on July 1 for 100-ton mining and infrastructure trucks using the 49-inch E4 size. Beyond the initial 27.00R49 size now being introduced to North America, additional sizes of the tire will be available: 24.00R35 in September 2010, and 21.00R33 and 18.00R33 in 2011. The new tire features a tread that is up to 13-percent deeper, which extends tire life by up to 15 percent, according to the manufacturer. Write 57 on Reader Service Card.
Best-in-class bucket breakout force in compact track loaders
Kubota Tractor has entered the compact track loader market with two models, the 75-horsepower SVL75 and the 90-horsepower SVL90. Both models — designed, engineered and manufactured by Kubota — have what the company calls a “best-in-class bucket breakout force.” The SVL75 has a 6,204-pound bucket breakout force and a 4,881-pound lifting capacity. The SVL90 has a bucket breakout force of 7,961 pounds and a lifting capacity of 5,869 pounds. Both models are powered by a four-cylinder, direct-injection, turbocharged Kubota diesel.
