This guide, representing bucket sizes not necessarily manufactured by
Deere, will help you in selecting proper bucket size for material density,
loader configuration, and operating conditions. Optimum bucket size is
determined after adding or subtracting all tipping load changes due to
optional equipment. The “conservative load” line on this guide is
recommended when operating in conditions such as soft ground and
unlevel surfaces. The “maximum load” condition on this guide is
sometimes utilized when operating on firm ground and level surfaces.
