Engineered from the ground up, ASV's ISR-4 undercarriage gives the new SR-80compact track loader 2.84 psi of ground pressure with 20-inch-wide tracks. Independent, multi-level suspension has four wheel carriages on each side that flex independently for maximum ground contact, the company says. Because the undercarriage flexes in multiple directions, the loader exhibits high levels of traction and sensitivity to the ground. The Perkins turbocharged diesel is ratedat 80.5 gross horsepower, and the loader's tipping load of 6,200 pounds gives it a 3,100-pound operating capacity. Estimated list price: $47,344.
