With impressive digging and high tractive power, the Doosan DL420-5 wheel loader excels in tough applications. It's designed to take on a wide range of material handling tasks from loading and transporting granular material (such as sand and gravel) to industrial, mining and quarrying applications.

Powered by a powerful Tier 4 diesel engine, you'll penetrate tough materials, tilt and lift with ease, and carry more in every cycle. Performance features include a powershift transmission with optimized hydraulic pumps, multiple power modes, Z-bar lift arm, return to dig, and limited slip differentials on both front and rear axles.

With the high lift option, you’ll gain additional lift height and reach. Easily load materials like cement, coal, grain, fertilizer, or waste into high-sided trucks, hoppers or mixers. High lift is ideal for processing plants, scrap and recycling facilities, and agricultural operations.
