PowerFold® Electric Deck Lift
Standard on all FrontMount™ DuraMax® decks, PowerFold® is the zero-turn mower industry's first electric deck lift (introduced in 2004).
PowerFold® rotates the deck nearly 90 degrees to provide easy access to the underside of the deck for simplified maintenance and mulching package installation, plus space-saving portability and storage.
The feature also adjusts cutting height between 1.25 and 5.0 inches and controls deck lift functions using a single switch.
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
Minimal Maintenance
- Fewer than 10 grease points and easy top-side access to belts and filters
- 1,000-hour transmission fluid change intervals
- Self-tensioning belts minimize cost and labor on routine maintenance
T6® Drive Hydrostatic Transmission

The deep-cushioned, deluxe Premium Comfort Seat features a coil-spring suspension and padded lumbar support for all-day comfort. Iso-mounting eliminates vibration before it reaches the seat, and both padded seat and 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, ignition and push/pull PTO switches, angled View-Eze™ console and adjustable cup holder are well positioned for visibility and ease of reach. -
