A HISTORY OF SUCCESS
Versatile was the rst company to massproduce articulated four-wheel drive
tractors, starting in 1966 with the D100
and G100 four-wheel drives. ose
ground-breaking tractors were primitive
by modern standards, with a 6-cylinder
diesel or 8-cylinder gas engine producing 100 horsepower. 1966 models sold
for less than CA$10,000.
Four-wheel drive demand increased
signicantly, with Versatile becoming
one of the leaders in four-wheel drive
development and production. By the
late 1970’s the Versatile lineup included
tractors ranging from 220 to 330
horsepower. With the 1980’s came an
expanded line of four-wheel drive tractors that stretched to 470 horsepower
in the Versatile 1150.
In 1987, Versatile was acquired by
Ford New Holland and by 1989 the
four-wheel drive tractors assembled at
the Winnipeg factory were painted in
the Ford colors, blue, black and white,
and carried the Ford Versatile name.
Production of blue four-wheel drive
tractors under the New Holland name
continued until 2000.

History of Versatile
Buhler Industries, a Canadian-owned
farm equipment manufacturer, purchased the Winnipeg four-wheel drive
plant from New Holland and in 2001
the Versatile name returned. Buhler
Versatile continued to build the 2000
Series four-wheel drive (240 to 425
horsepower) and launched the High
Horsepower Tractor Series in 2004.
With 435, 485 and 535 horsepower it
was the highest-horsepower four-wheel
drive available in North America.
Buhler celebrated 40 Years of Versatile tractor production in 2006 and
commemorated 50,000 VersatileBuilt four-wheel drives in late 2007.
At the same time, Combine Factory
Rostselmash Ltd., a Russian combine
manufacturer, purchased Buhler Indus-
tries with plans of increasing the global
presence of Buhler Versatile four-wheel
drive tractors. e Versatile name
continues, known worldwide for reliability, durability and ease of service and
maintenance.

THE POWER TO PERFORM
Proven Power
Versatile tractors have been powered
by Cummins engines for nearly 40
years. Cummins engines employ the
latest advancements in diesel engine
design and technology to provide
long-term reliability. ese engines
are turbocharged and aercooled for
clean-burning fuel eciency. e highpressure injection system with electronic
engine control quickly responds to load
conditions or throttle adjustments,
with a 35% torque rise at 1400 RPM
and a 7% power bulge at 1800 RPM to
meet the rigorous demands of modern
agricultural operations.
Biodiesel approved
e Cummins QSM and QSX
engines are Tier 3 compliant and
meet the stringent Tier 3 NOx emissions requirements by optimizing the
in-cylinder combustion system and
without the need for any additional
emissions subsystems. ese engines
have proven track records of excellent
fuel economy and are approved for B20
biodiesel in a continuing eort to support new fuel initiatives.
Bigger radiator, better cooling
e cooling system on Buhler fourwheel drive tractors uses a large grille
and radiator to provide better air ow.
e larger surface area reduces the
air velocity required for engine cooling, which results in more ecient fan
horsepower consumption. Some fourwheel drive tractors have smaller hoods,
compromising cooling surface areas,
meaning more air needs to be pumped
through the radiator, drawing valuable
engine horsepower to run the fan.
Cummins QSM11
e Cummins QSM11 powers the
305, 340, 375 and 400 models. e 11liter in-line six-cylinder turbocharged
engine delivers superior performance
using advanced combustion technology. e turbocharger is designed for
optimum boost to improve throttle
response across the operating range.
Electronically controlled unit injectors
with cam-driven rate shaping optimize
both emissions and eciency. e

engine. Buhler selected the Cummins
QSX15 during the development of
the HHT Series to optimize the performance of the tractor, shaping power
curves and ratings to align with work
environment, load factors and operating modes. e result is an ecient and
reliable high horsepower tractor that
will work hard for years to come.

GET IN GEAR
Transmission choices
Each farm has specic operating conditions and implement demands and
Buhler Versatile four-wheel drive tractors oer the choice of manual or
powershi transmissions, each developed to eciently manage eld demands
and engine horsepower. Choose the best
transmission for convenience, performance and operating conditions.
Manual transmission
e mechanical 12 x 4 transmission
features four synchronized sequential
smooth-shiing gears in each of its three
ranges. ese gears have closely matched
speed increments in the critical band
from 3 to 8 mph to provide exibility
for every farming application.
Powershift transmission

a CAT® TA22 Powershi transmission
with 16 forward speeds and 4 reverse
speeds, with eight gears in the heart of
the critical eld working range. Single
lever control provides clutchless shiing from forward to neutral to reverse
for all speeds. Powershi gear selection
POWERSHIFT FEATURE DESCRIPTION
