Fastback™ PRO Rear-Discharge Mower Deck

Top‑down view of zero‑turn mower showing the operator area with a yellow seat, control levers, perforated deck surface, and twin mower housings on either side.

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.
