The Groundsmaster® 5900 Tier 4 series mowers can mow up to 8.4 hectares/hour*. And to match the 16-foot (4.9 m) wide mowing brawn and the 31% fuel-saving^ gain with Tier 4 Yanmar® 3.3 L engine, the 5900 T4 series is loaded with intelligence.
Smart Power® allows the operator to effortlessly maintain the correct speed for optimal cutting, while the SmartCool™ system prevents over-heating with auto-reversing cooling fans. An onboard InfoCenter™ gives the operator a quick read on all systems.
The ROPS-certified cab comes standard with air conditioning and heat and pre-filter kit as well as superb all-round visibility. Easy access for maintenance, front and rear opening windows for 100% outside airflow and low profile roof are some of the features of this Toro factory-fitted cab.
The new Groundsmaster 5900 Tier 4 series proves beyond doubt that increased efficiency and ease of operation lead to higher productivity and low daily operating costs.
*Maximum mow rate is calculated at 17.4 km/h with no overlap or stops. Actual mowing rate may vary depending on operator and conditions. ^compared to previous Groundmaster 5900 T3 Series models. Based on side-by-side mowing.

New Improved All-Season Safety Cab
Feature a NEW climate-controlled safety cab, with low profile roof, rollover protection and a pressurised air filtration system that keeps dust and debris out. Our air-conditioned safety cab will keep your operators at their best, no matter what the outside temperature. With 5 individual air-vent controls with full 360 degree rotation for improved operator comfort and increased defrost capability.
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.
Flexible Cutting Width
With the ability to mow widths ranging from 145 cm to 490 cm the Groundsmaster 5900 has the flexibility necessary for nearly any mowing need. The ability to mow a 0 cm uncut circle – without wheel brakes – allows you to easily mow striping patterns without leaving any grass uncut.
SmartCool™ Auto-Reversing Cooling Fan
Engineered with our exclusive SmartCool™ technology, so when things heat up under the hood, the system briefly reverses the cooling fan to blast chaff and debris from the air intake screens. The result, is non-stop improved productivity.
Full-Time, Bi-Directional 4WD and All Time Traction Assist
The full-time, 4-wheel drive puts power where it’s needed. The cutting decks automatically take weight off the cutting units for more floatation, and put it on the traction wheels when climbing hills. CrossTrax® all-wheel drive system offers increased cross wheel traction control.
Onboard InfoCenter™
The onboard InfoCenter™ displays clear and simple operating information at a glance, while constantly monitoring the internal health of the machine. Audible and visible alarms notify the operator of a potential problem. In the field or at the workshop, technicians can quickly identify the source and solution.
Smart Power®
If the blades get bogged down, Smart Power adjusts their speed for proper cut. Individual deck motors control blade speed for the best after-cut appearance.
eFan Cooling System
Two independently controlled 24v electric fan banks provide system cooling for hydraulics and engine.
Reduced Operator Vibration
The air-ride suspension seat adjusts to the operator’s desired firmness for maximum comfort. The seat adjusts with easy moves of height and angle levers for an ergonomic fit to the operator, and the armrests adjust to a comfortable angle.
Integrated ControlArm™ with Fingertip Electronic Controls
Controls are logically organised and easy to access from the operator’s seat control arm.
