Features

Features

  • MORE CAPACITY, MORE PRODUCTIVITY: The optional powered dump attachment system means less time emptying and more time mowing. An exclusive baffle design fills, evenly back to front, for maximum efficiency on large lawns.
  • EASY TO MAINTAIN: Landscape professionals can spend more time mowing and less time maintaining their commercial mower.
  • FILL REDUCTION: The Navigator’s patented fill-reduction system lets you bag 100%, bag 33% and mulch 67% or mulch 100%. All with its versatile cutting deck and baffle system.
  • “FEATHERTOUCH” CONTROLS: As the name implies, you don’t have to muscle the Navigator around. Its FeatherTouch controls make maneuvering tight spots virtually effortless.
  • HEAVY DUTY GEAR BOX: Superior gear with spiral-bevel cut gears. Rated at 50hp for improved durability.
  • DECK DEPTH: 4 5/8 inch deep deck allows for improved productivity and durability.
  • BLOWER SIZE: Larger diameter blower helps improve hopper fill and reduce plugging.
  • ENGINE ORIENTATION: Orientation of the engine draws air from the front of the machine over the belts, pumps and through the engine to the rear of the machine extending driveline component life. Fuel tank pivots out for easy servicing of the engine.
