Structure

Box-section main frame is designed to handle heavy loads, while Z-Bar linkage maximizes breakout force.

Main Frame Design

Strong box-section main frame design, with continuous, deep-penetration welds resists twisting loads to protect components from excessive wear.

Z-bar Linkage

Breakout force is exceptionally high due to the mechanical advantage of Z-Bar linkage design.

Ground-level access to lubrication points. Hinged doors allow quick access to the engine, hydrostatic system along with the battery and tool boxes.

Easy Diagnosis

The Computerized Monitoring System and self-diagnosing EHC work together to warn against both occurring and impending faults to reduce downtime. Rapid, easy calibration and troubleshooting of hydrostatic and electrical systems are performed through CMS and EHC systems. Electronic Technician (ET) software is fully compatible with the EHC and provides further diagnostic capabilities. Quick-disconnect hydraulic pressure taps allow quick diagnosis of the hydraulic system. More commonly used pressure taps are clustered inside the left engine door for easy access.
