What will your next 16' (4.9 m) rotary mower do for you?
Will it reduce your fuel and maintenance costs? Automatically
clear chaff from the intake screens? Or tell the operator when
there’s a potential problem … and then point the technician
directly to the trouble spot? If your next mower is the
completely new Toro® Groundsmaster® 5900 or 5910,
the answer is “Yes” and much more.
Welcome to the next generation of wide area rotary
mowers. The Toro Groundsmaster 5900 Series sets the
new standard for productivity, uptime and low daily

Toro Groundsmaster mowers are renowned for their power,
durability and reliability. After listening to customer input,
our engineers set out to build a mower unlike any other.
The 99 hp (74 kW) turbo-diesel engine powers you through
the toughest turf. Sophisticated onboard diagnostics and
an innovative cooling system maximize uptime. And for
ultimate operator comfort, the 5910 offers a factory installed
climate-controlled cab.
The power authority.
Get more productivity with a surprising mix of fuel
flexibility, efficiency, low emissions and unstoppable
power. The gutsy Cummins QSB3.3 inline 4-cylinder engine
puts out 99 hp (74 kW) and 306 lb-ft (415 N•m) of torque
to cut the thickest, wettest grass you can find. All while
exceeding EPA and EU emissions standards for nonroad
diesel engines.
Fuel costs are squeezing budgets everywhere. We’ve
responded with a high pressure common rail (HPCR)
electronic fuel delivery system that provides fuel efficiency
and delivers responsive power at every RPM. This flexible
engine is also biodiesel ready for lower emissions and
reduced environ350
mental impact.

Equipment downtime is productivity’s worst
enemy. With the all-new Toro® InfoCenter, you
get helpful maintenance reminders and instant
notification of potential problems. It’s like having
a mechanic on board.
During normal operation, the 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 shop, technicians can quickly
identify the source and solution. No handheld or
diagnostic computer is needed – all readouts are
displayed within the onboard unit.
• Multi-function sensing
• Maintenance reminders
• Visible and audible trouble alarms
• Supervisor mode

The hood lifts at the rear for easy access and maintenance of the engine, oil cooler, charged air-cooler and
radiator. You can remove both side panels and the thermoplastic hood in a snap.
SmartCool System:
cool aid.
Tired of losing valuable work time from
overheating? Now you can reduce downtime
with our exclusive SmartCool System. Before
things get too hot, SmartCool briefly reverses
the cooling fan to blast chaff and debris from
the air intake screens.
The innovative Toro SmartCool System, along
with regular maintenance of the cooling system,
keeps operators on the job and moving forward.
Smart? You know it. Cool? Definitely!
• Sensor-triggered fan reversal clears chaff buildup
• Function shown on Toro InfoCenter display
• Reduces operating downtime

A comfortable operator is safer,
happier and more productive.
Ergonomic seating and one-touch
controls put the operator in total
command. Rubber mounts isolate
the entire operator platform from
the frame, greatly reducing vibration
and improving comfort.
The climate-controlled
Groundsmaster® 5910 provides
protection and comfort in extreme
temperatures. Operators work
confidently in a fully-enclosed,
factory-installed cab, with a fourpost, rollover protection structure
(ROPS) and tempered safety glass.
The front and rear windows open for
ventilation. A windshield washer and
wiper help maintain visibility when
the weather turns bad.
Keep your cool.
Even a small increase in temperature can have
substantial effects on operator efficiency and
safety. A case study by the Society of Automotive
Engineers* showed a 50% increase in missed
driver tasks and 22% slower reaction times
at 81°F (27C) in the operating compartment
compared to a temperature of 70° (21C).

The Toro® 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.
The steering tower quickly tilts to provide the
best fit and visibility of the Toro InfoCenter™
display, for a tuned-in, comfortable ride.

your cut.
The 5900 Series is all about covering
maximum ground. With the cutting decks
down, you get a full 16' (4.9 m) cut capable
of mowing more than 100 acres (40.5
hectares) per day.
To mow between objects or along narrower
areas, operators may raise either left or right
wing decks (142" width of cut) as well as both
decks (92" width of cut). The cutting units
can be set from 1-6" (2.5-15.2 cm) to handle
a wide variety of conditions.
The rotary cutting blades are mounted on
hefty 1.25" (3.2 cm) diameter spindles found
on all Groundsmaster® models with 9.5"
(24.1 cm) cast iron housings. These are the
toughest spindles in the business, ready for
years of constant cutting.
Can take a hit.
Built with high-strength, reinforced steel, these decks
stand up to years of use. If the operator misjudges
distance, the unique, bi-directional impact absorption
system prevents damage and costly repairs. A massive
spring-loaded shock cushions the decks from front or
rear impact, and lift arms swing the decks away
from the object.
Get down to
business – fast.
The Groundsmaster 5900 Series mowers can travel
from site to site at transport speeds up to 20 mph
(32.2 km/h). The center cutting deck lifts and wing
decks rise vertically, allowing clear side and rear views.
The road package is standard and includes head lights,
turn signals, flashers, brake lights, and a slow-moving
vehicle sign. Optional front and rear work lights are
also available.
No uncut grass left behind.
U-turns welcome.
The Toro Groundsmaster® 5900 Series offers superior traction and maneuverability.
Other 16’ (4.9 m) mowers leave an 18” (45.7 cm) diameter uncut circle, which requires extra time to make
another pass. That’s not good enough for the 5900 Series. Now you can mow closely around trees and other
obstacles with zero trim. You can also turn 180° and leave no uncut grass.
4WD: go where you want.
The full-time, 4-wheel drive puts
power where it’s needed. The
cutting decks automatically take
weight off the cutting units for
more flotation, and put it on the
traction wheels when climbing
hills. Individual wheel brakes and
4WD flow divider can be used
to provide additional traction
