Heavy-duty Deck

- Extra-deep, 5.5-inch deck is fabricated from heavy-gauge formed steel with a reinforced anvil edge
- Specially designed cutting chambers enhance airflow for better cut quality
- Deck easily converts from side discharge to optional Down Discharge™ mulching or PowerVac™ collection
- Sentry™ spindles with massive, 8-inch flanges anchored in a 6-bolt pattern, spread the force of impact for greater strength
- Spindle planes are fabricated from double-layered formed steel laminate and combine with the spindles to form a triple-strength deck to keep blades level and deliver a high-quality cut.
- Sentry™ spindle guards shield spindle housing and seal lower bearings from fiber wrap and dirt ingestion
Ultimate Operator Station™
The deep-cushioned, deluxe Premium Comfort Seat features a coil-spring suspension and padded lumbar support with sliding 2-inch fore and aft adjustment for all-day comfort. Iso-mounting eliminates vibration before it reaches the seat, and both padded seat and foldable armrests are covered in scuff-resistant, breathable CoolTemp Cordura® fabric, which dissipates heat and won’t tear or crack with extended use.
Operational controls including throttle, choke and angled View-Eze™ console and adjustable cup holder are well positioned for visibility and ease of reach
One- or two-handed operation with ComfortReach™ adjustable Hydra-Smooth™ dual levers that automatically return to neutral from either forward or reverse position.
