Residential Use: 4-year or 800-hour (whichever comes first); limited warranty covering parts and labor.

RUGGED CONSTRUCTION
Robotically-welded steel construction for long-lasting durability
Centered-bearing design provides greater load-bearing capacity to handle the weight of operator, fuel and high-capacity collector with reserve strength for curb shocks and weight shifts
Tough-as-nails powder-coated finish is fusion-bonded for chip and rust resistance

REDUCED MAINTENANCE
Only two Access-Eze™ lubrication points cut maintenance time up to 95%
Self-tensioning belts minimize cost and labor on routine maintenance

ULTIMATE OPERATOR STATION®
ComfortZone™ seat eliminates jostles and jolts with coil-spring suspension and a fully padded, high-back seat, padded armrests and variable density foam cushion. Iso-mounting smooths the ride, erases fatigue and keeps the operator comfortably in control at faster mowing speeds
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.

Roomy, iso-mounted, shock-absorbing footrest

VIGILANT OPERATOR PRESENCE SYSTEM™
Standard, low profile Roll-over Protection System (ROPS) structure with an adjustable seatbelt
Dampened steering levers that return to neutral from forward and reverse
Interlock switches that shut down the engine when the operator leaves the seat while PTO is engaged or levers are in drive position

HIGH TEMPERATURE CLUTCH CUT OUT
Equipped with a High Temperature Clutch Cut-Out that automatically disengages the PTO if engine temperature reaches a certain point to prevent engine damage
