Fast and powerful to get the job done on time, every time. 

The Grasshopper 400D 1.3L zero-turn lawn mower features the legendary power of a Kubota 3-cylinder MaxTorque™ Clean Diesel engine that delivers best-in-class torque and fuel economy. Commercial landscapes depend on Grasshopper mowers for their comfort, performance, productivity, quality and dependability.

Kubota Diesel Engine

  • EPA Tier 4 Final-compliant 77 cu. in. (1.3L) , 3-cylinder, liquid-cooled Kubota Clean Diesel engine with horizontal crankshaft and pressure lube for smooth, reliable operation

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 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, choke and angled View-Eze™ console and adjustable cup holder are well positioned for visibility and ease of reach
  • One or two hand steering system with QuikAjust Tilt™ dual levers with 9-inch comfort range that automatically returns the levers to the neutral position from the forward or reverse position.

    Hydraulic Height Adjustment

    • Hydraulic Height Adjustment for MidMount DuraMax™ decks 61-inches and larger allows operators to raise and lower cutting height at infinitely variable settings with toggle switch control. Standard on 400 Series models.

    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

    Reduced Maintenance

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

    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

    Design-Matched G2 Transmission

    • 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

      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

      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

      Premier Suspension Seat

      Premier suspension seat provides the ultimate in operator comfort. Low-profile seat slides fore and aft and includes an integrated shock absorber that manually adjusts to operators between 100 – 300 lbs. Other ergonomic features include a backrest that tilts from -5 degrees to +30 degrees, a lumbar support mechanism, adjustable armrests and a retractable seat belt.

      Shielded Sprayer

      Accepts 53-inch, 30-gallon shielded sprayer, which features aerodynamically designed shields and fully shielded curtains to contain chemical spray. Four-nozzle spraying chambers apply small droplets that "stick" to vegetation for more coverage per tank using less chemicals.

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.

      Wide Seat Conversion Kit

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