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. These engines
are turbocharged and aftercooled for
clean-burning fuel efficiency. The high-
pressure 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
The Cummins QSM and QSX
engines are Tier 3 compliant and
meet the stringent Tier 3 NOx emis-
sions requirements by optimizing the
in-cylinder combustion system and
without the need for any additional
emissions subsystems. These engines
have proven track records of excellent
fuel economy and are approved for B20
biodiesel in a continuing effort to sup-
port new fuel initiatives.
Bigger radiator, better cooling
The cooling system on Buhler four-
wheel drive tractors uses a large grille
and radiator to provide better air flow.
The larger surface area reduces the
air velocity required for engine cool-
ing, which results in more efficient fan
horsepower consumption. Some four-
wheel 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
The Cummins QSM11 powers the
305, 340, 375 and 400 models. The 11-
liter in-line six-cylinder turbocharged
engine delivers superior performance
using advanced combustion technol-
ogy. The 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 efficiency. The
