About the Bobcat 742B & 743B Series Loaders
The Bobcat 742B and 743B represent the peak of the 740-series evolution, engineered for high productivity in landscaping, construction, and industrial material handling. Known for their rugged durability and zero-turn maneuverability, these "B-series" loaders introduced improved cooling capacities and refined hydraulic controls. The 742B offers reliable liquid-cooled gasoline performance, while the 743B provides the heavy-duty diesel torque required for the most demanding job sites and long-duration work cycles.
While these loaders are built for heavy-duty cycles, their hydrostatic pumps and transverse-mounted engines require precise mechanical maintenance to ensure safety and longevity. This manual provides the specific flow rates and pressure curves unique to the B-series, ensuring that your machine maintains its original breakout force and travel speed. With their simple, rugged design and wide-access service points, these loaders are built for the long haul, and this manual is the essential partner for their entire lifecycle.
