Work Made Easy
OPTIMIZED Z-BAR LINKAGE
The optimized Z-bar linkage combines the digging efficiency of a traditional Z-bar with integrated tool carrier capabilities for great performance and versatility. Visibility to bucket corners and fork tips at ground level remain excellent while sight lines at maximum lift are improved with a Generation III lift arm design. Lift higher and reach further with optional High Lift linkage available on all three models.
QUICK LOADING PERFORMANCE SERIES BUCKETS
Performance Series Buckets deliver up to 10% higher fill factors compared to previous models, better material retention for significant productivity and fuel efficiency improvements. The buckets feature a longer floor to take a bigger bite of the pile, an open throat to heap higher and curved side bars to help with material retention.
