The 530X model mini-skid includes a powerful, fuel-efficient 30-hp Kohler Command Pro air-cooled gas engine and a two-pump, 3,000 psi, 14.5 gpm hydraulic system. Units have enough power to handle full-size attachments, and both the Boxer 530X and the Boxer 526DX (diesel unit) offer an integrated track system that retracts from a fully extended 43.5 inches to a width of 35 inches. Nine-inch-wide individual tracks provide a low 3.3 psi of ground pressure.
