824 Wheel Dozer

MOBILE. AGILE. VERSATILE.

Cat® wheel dozers combine the power of a track dozer with the mobility of a wheeled machine to help deliver high production at low operating costs in a variety of applications — from surface mining cleanup to coal stock piling, road maintenance to reclamation.

Cat wheel dozers are designed with durability built in, ensuring maximum availability through multiple lifecycles. With optimized performance and simplified serviceability, our machines allow you to support your jobsite efficiently and safely while lowering owning and operating costs. The 824 continues our legacy of reliability, performance, safety, operator comfort, serviceability, and efficiency.
