Product Details

Overview

The Groundsmaster® 5900-D rotary mower offers an impressive 16' (4.88 meter) cutting width for making quick work of even the largest jobs. Equipped with a 72 hp (53.7 kW) diesel engine, the 5900-D is powerful and efficient. The onboard InfoCenter™ provides diagnostics to identify potential maintenance issues. These features, along with the SmartCool™ system with an auto-reversing cooling fan, ensure a long, productive life.

Features

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.

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).

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.

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.

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.

Smart Power™

Automatically adjusts the mower’s ground speed for the cutting conditions to maintain optimal power to the blades, taking the guesswork out of a consistent cut.

Groundsmaster® 5900 series feature - hybrid drive cutting deck

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.
