Features and benefits

Wheel loader_WA270_Literature link20160105WA320na_021.tif

Enhanced control with HST

Help minimize wheel slippage and promote extended tire life with a smooth variable speed traction control system that helps keep your operator in control in virtually all working conditions. Auto-mode automatically adjusts without operator input, helping to keep loads stable.

Versatile PZ linkage plus high breakout force

Powerful breakout force and stability. Parallel-lift linkage with large break-out force and auto tilt-in feature simulates a Z-bar, which promotes material retention, helping operators save time and finish jobs faster.
