Mows 20.8 Acres/Hour
One Groundsmaster 5900 has the equivalent production of two 11 ft (3.4m) mowers or four 6 ft (1.8m) out front rotaries.
|

0" Uncut Circle
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.
|

Smart Power® Traction
Smart Power Traction allows even an inexperienced operator to achieve a consistent cut, even on hills and thick patches. By automatically adjusting ground speed when encountering heavy cutting conditions, optimum blade speed is maintained.
|
EnergySmart Efficiency
We designed this machine to be powerful, yet energy efficient. System designs improve horsepower efficiency through: Hydraulics: (12hp savings) Cooling: (7hp savings) Cutting: (10hp savings). |
SmartCool™ System with Auto-Reversing Cooling Fan
Variable speed, temperature actuated reversing fan. Blows chaff off intake screen to help reduce overheating. Big time saver which reduces the amount of times an operator has to stop and exit the unit to clean the back hood. |

Heavy Duty Spindle
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.
|

Reduced Operator Vibration
4-way adjustable seat and air-ride suspension isolate the operator platform to reduce noise and vibration.
|
Onboard InfoCenter™
The onboard InfoCenter™ gives the operator a quick read on all systems and even provides assistance at the right moment. |

Powerful Tier 4 Engine
3.3L (202cu. in.) Yanmar Tier 4 Final Compliant turbo-diesel engine, 72 HP (53.7kW) @2500 rpm, 206 lb. ft. (279 Nm) torque @1625 rpm, B20 diesel compatible.
|

Flexible Cutting Width
With the ability to mow widths ranging from 57" (145 cm) to 192" (487 cm) the Groundsmaster 5900 has the flexibility necessary for nearly any mowing need.

HybridDrive™ Cutting Deck System
Belts transfer power more efficiently than hydraulic motors while adding a layer of protection against hydraulic failures. Large diameter spindle housing dissipates impact loads, and dual tapered roller bearings last up to six times longer than ball bearings.
