CLEAN DIESEL AND AUTONOMOUS OPERATION ARE KEY TECHNOLOGIES BOOSTING
PERFORMANCE TO SERVE GROWING POPULATIONS WITH INCREASING MECHANISATION
iVTInternational.com September 2019
Cummins has a longstanding history of powering
agricultural equipment. The company’s products
range from diesel and natural gas engines to hybrid and
electric platforms, as well as related technologies
including transmissions, battery systems, fuel systems,
controls, air handling, ltration, emission solutions, and
power generation systems. Cummins recently
announced its latest Stage V B6.7 Performance
Series engine will be available in Claas Avero
combine harvesters from Q4 of 2019.
Cummins B6.7 engine has been integrated with Claas’
powertrain to deliver the optimum t and performance
for the Avero. Delivering 157kW (213hp) maximum
power and 990Nm peak torque in Claas’ larger model
and 123kW (167hp) and 746Nm peak torque in the
smaller model, the B6.7’s power and torque curves have
been tailored speci cally to Avero’s duty cycle. This is
achieved using Cummins’ in-house electronic controls,
fuel injection, air handling and exhaust after treatment
technologies.
Ann Schmelzer, general manager of global agriculture
at Cummins, says, “During the integration process, we
worked closely with Claas to understand the
requirements of both their machine and their customers,
the farmers who operate Avero. As such, the B6.7 engine
delivers the high power density, machine capability and
e ciency required from a combine harvester, while its
simpler architecture with fewer parts means higher
reliability, easier accessibility, less maintenance and
more productivity for farmers.”
While many manufacturers have adopted a ‘same as’
strategy from Stage IV to Stage V, Cummins technology
leadership means its Stage V products deliver more
power and less complexity through the removal of
exhaust gas recirculation (EGR) on engines up to 12 liters
displacement. Stage V emissions requirements are met
through Cummins’ Single Module after treatment
system, which combines a diesel oxidation catalyst
(DOC), a diesel particulate lter (DPF) and selective
catalytic reduction (SCR) in a single unit. The system is up
to 40% smaller and 20% lighter than Cummins’ Stage IV
solution and features a compact AdBlue/DEF mixer that
removes the need for a decomposition reactor tube. This
makes the whole system easier to keep clean.
Cummins decision to remove EGR at Stage V o ers
bene ts for Claas’ global operations, as well as for its
farming customers. Without EGR, the same Cummins
engine platform can be applicable for sales to multiple
emissions standards, from Stage V and Tier 4 nal and
all the way down to unregulated levels.
“We’re really excited to be powering the Avero and
we know that e ciency and productivity are key to the
Inset: Claas benefi ts from
the B6.7 engine (below)
success of the
whole Claas
Power Systems
(CPS),” says
Schmelzer. “Our Stage
V Performance Series
technology works to those
objectives. Not only does it provide e ciencies to Claas
through regional installation commonality, but farmers
get fuel e cient, reliable performance in a simpler and
easier to maintain engine package.”
Manufacturing for all
Cummins B6.7 Performance Series engines are
manufactured at its Darlington, UK plant and mark
the latest development for Cummins in the agriculture
sector. This year marks 100 years of diesel engine
development and production for Cummins, which began
with engines rst used in farming. From this foundation,
farmers have seen the introduction of a range of new
technologies and manufacturing milestones. Cummins
partnered with Versatile in 1967 – the rst company to
mass-produce articulated 4WD tractors – and the
partnership is still going strong more than
50 years later with all Versatile equipment
powered by Cummins engines.
The Performance Series engines are
also put to use in diverse applications such
as Hardi’s self-propelled sprayer range powered by
the B4.5, B6.7 and L9 Performance Series, and Agrifac’s
Condor Endurance II self-propelled sprayer. The new
engine technology brings more machine capability,
increased fuel e ciency, more productivity and lower
cost of ownership.
Being heralded as the future of farming,
autonomous farm machinery is also bringing new
solutions for farmers. Cummins is at the forefront
of these developments by powering the world’s rst
autonomous orchard sprayer, the Global Unmanned
Spray System (GUSS). Its cutting edge technology and
design delivers delivers precision fertilizer application
for trees such as almonds, pistachios, citrus and fruit.
In addition, the DOT Power Platform powered by
Cummins has brought robotic technology to the
agricultural industry.
From the rst engine for a farm pump a century ago,
to powering sprayers, tractors and combine harvesters,
alongside the latest autonomous technology, Cummins
has demonstrated its commitment to shaping the future
of agricultural machinery. To nd out more about
