Models depicted on this site may be shown with optional equipment.

  • Robotically-welded, high-grade steel construction and I-beam reinforcement for long-lasting durability
  • Centered-bearing design provides greater load-bearing capacity to easily 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

  • Rugged G2 transmission with auxiliary cooling fans, HydroGear variable displacement 21 cc piston-type pumps and high-torque Parker wheel motors
  • CoolFan™ hydro cooling system with 7-micron absolute filter for cooling efficiency
  • Delivers smooth response and requires less maintenance, with industry-leading 1,000-hour fluid change interval

  • Add or remove implements in minutes without tools with QuikConverter™ Implement System
  • Equip your out-front mower with a wide range of tools, including turf cleanup, renovation and snow removal implements that extend your productivity year-round

  • 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

Standard on all FrontMount™ DuraMax® decks 48-inch and larger, 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 1.0 and 5.0 inches and controls deck lift functions using a single switch.

  • 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

  • Commercial Use: 3-year unlimited hours; limited warranty covering parts and labor.
  • Residential Use: 4-year or 800-hour (whichever comes first); limited warranty covering parts and labor.

  • Equipped with a High Temperature Clutch Cut-Out that automatically disengages the PTO if engine temperature reaches a certain point to prevent engine damage

Wide stance single-fork tail wheels provide increased flotation and stability for a smoother ride.

Hydraulic Lift raises the front of the deck to maneuver over soft or uneven ground and to clear curbs, trailer ramps and other obstacles, operated by a lift switch on the steering lever.

Two USB Charging Ports

Electronic Fuel Gauge/ Digital Hour Meter

LED work lights provide improved visibility in low light situations.

  • 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

  • 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 QuikAjust Tilt™ dual levers with 9-inch comfort range to custom fit operator's reach. Levers automatically return to neutral from either forward or reverse position and are less strenuous than riding mowers with steering wheels.

Provides additional seating room for larger operators or to accommodate cell phones or pagers. Requires seat belt extension.

Yellow beacon attaches to OPS to provide greater visibility in high-traffic areas.

The optional Down Discharge™ mulching package with GrassMax™ High-Low Mulching blades cuts and recuts clippings and directs them deep into the turf, enriching turf and producing a beautifully manicured cut.

The optional SpeedTrimming™ heavy-duty, anti-scalp roller kit for 52-inch and larger DuraMax® decks speeds close trimming near buildings, fences retaining walls and other landscaping features. Kits available for both left and right sides of cutting decks.

Used in conjunction with PowerFold® electric deck lift/height adjustment, this armrest-mounted switch controls deck lift functions and adjusts cutting height between 1.0 and 4.5 inches on the go.

Provides an additional two inches of leg clearance.

The optional Premier Suspension Seat offers the ultimate in comfort and an extra measure of suspension while mowing over rough ground. Adjustable backrest, armrests and lumbar support with weight-adjusted suspension control provide maximum comfort for operators of all sizes and preferences.

Allow for controlled side-to-side flotation of the deck in rolling terrain for a smooth, even cut.

Available for 61- or 72-inch deck options, heavy-duty anti-scalp rollers facilitate faster trimming and eliminate scalping.

The Foldable ROPS allows the two-post ROPS to be lowered for mowing under low-hanging trees and other overhead obstacles, or for storing and transporting in enclosed trailers with low door clearance. CAUTION: Avoid drop-offs, embankments and steep slopes. Do not allow ROPS to provide a false pretense of security in hazardous areas and avoid questionable conditions. Always wear seatbelt when Foldable ROPS is in up-right position. When Foldable ROPS is down, DO NOT use seat belt, and drive with extra caution.

Turf-tread tires provide enhanced traction and handling on level terrain. Turf-tread tires are optional for 700 and 900 Series FrontMount™ models.

Dual-fork tail wheels or wide stance single-fork tail wheels.

Every FrontMount™ mower accepts a range of time- and labor-saving QuikConverter™ implements for even greater flexibility and productivity year-round.

Diamond-plated aluminum canopy is highly resistant to abrasions. Easily mounts to ROPS to increase operator comfort by limiting exposure to direct sunlight and reducing eye strain.

Multi-channel sprayer combs water pressure between radiator fins without damage, dislodging packed-in dust and debris that can become an invisible source of engine overheating.

Engine Block Heater helps warm the engine for easier starting in cold weather.
