About the Bobcat 440 & 443 Series Loaders
The Bobcat 440, 443, and 443B are iconic compact loaders engineered for high productivity in incredibly tight spaces.

The 443B series brought refined controls and improved cooling, making it a favorite for demanding daily use in commercial applications.
While these loaders are built for longevity, their compact hydrostatic pumps and transverse-mounted engines require precise mechanical maintenance to ensure safety and prevent overheating. This manual provides the specific flow rates and pressure settings unique to these models, ensuring that your machine maintains its original breakout force and travel speed. With their simple, rugged design and versatile attachment compatibility, these loaders remain essential workhorses, and this manual is the indispensable partner for their continued operation.
