Fastback™ PRO Rear-Discharge Mower Deck

The Fastback™ PRO rear-discharge system improves safety and productivity by minimizing debris throw and allowing closer mowing near obstacles. Ideal for public spaces, it ensures a tidy operation with better debris control around the operator.

7-Iron™ PRO Deck

This mower is equipped with a 7-Iron PRO side-discharge deck stamped from 7-gauge steel, offering superior durability and performance. The deck design provides a high-quality cut with excellent material processing and discharge capabilities.

ComfortGlide™ Seat System

The ComfortGlide™ seat system features adjustable suspension, allowing operators to transition more smoothly over bumps. It can adjust fore and aft, absorbing impacts for reduced operator fatigue during long hours of operation.
