Severe Duty

Extreme Duty

For higher abrasion conditions such as well shot granite and caliche. Example: Digging conditions where tip life ranges from 200 to 400 hours with Penetration Plus tips. ● Bottom wear plates are about 50% thicker than Heavy Duty buckets. ● Side wear plates are about 40% larger than Heavy Duty buckets for added protection against abrasive and gouging wear. ● Heavy Duty and Severe Duty buckets use same size adapters. ● Adapters are sized to accommodate higher abrasion conditions. ● Tips are up-sized (over the General Duty bucket) for enhanced performance and durability. ● Sidebars are pre-drilled for optional sidecutters and sidebar protectors.

For very high abrasion conditions including high quartz- ite granite. Example: Digging conditions where tip life is less than or equal to 200 hours with Extra Duty tips. ● Corner (or heel) shrouds, Base Edge End Protectors (BEEPs), base edge segments, liners, andMechanically Attached Wear Plates (MAWPs) protect the bucket from wear. ● Side wear plates are larger. ● Sidebar protection has been added for protection against abrasion and gouging wear. ● Adapters are sized to accommodate higher abrasion conditions. ● Tips are up-sized (over the General Duty bucket) for enhanced performance and durability.
