Simplified routing of the electrical and hydraulic systems helps boost reliability and ease maintenance. Wiring and hoses are placed for protection against wear and damaging bends.

The easy-to-use CVT transmission automatically senses the load and delivers more torque and tractive effort as needed to maintain the desired speed.

Steering sensors control articulation speed when nearing frame-to-frame contact, cushioning impact during full articulation and to enhancing operator comfort.

Two-speed 4000 and 6000 Winches increase line pull and is faster than the single-speed winch on previous models. Optional 16.3-square-meter (17.5 square foot) grapple on the 648L-II helps you deliver more wood to the landing with fewer skids, boosting productivity.

Combining impressive horsepower and power-to-weight ratio with a constant engine speed, the 648L-II delivers superb responsiveness with maximum efficiency. Rock-solid stability provides excellent pulling power, especially when climbing hills, navigating adverse terrain, or hauling bigger payloads.
