  • We designed this machine to be powerful, yet energy efficient.
  • Ductile cast iron spindle housing is large in diameter [9 in. (229 mm) at the base] to dissipate impact loads. Dual tapered roller bearings last up to six times longer than ball bearings.
  • The optional, factory installed, permanent safety cab protects the operator with a four-post rollover protection structure (ROPS), tempered safety glass, and climate controlled environment including both air conditioning and heater.
  • 4-way adjustable seat and air-ride suspension isolate the operator platform to reduce noise and vibration.
  • The ability to mow a 0" (0 cm) uncut circle - without wheel brakes - allows you to easily mow striping patterns without leaving any grass uncut.
  • One Groundsmaster 5900 has the equivalent production of two 11 ft (3.4m) mowers or four 6 ft (1.8m) out front rotaries.
  • The onboard InfoCenter™ gives the operator a quick read on all systems and even provides assistance at the right moment.
