Cummins Stage V B4.5, B6.7 and L9 engines will be integrated into Hardi’s self-propelled sprayer range to meet new EU emissions regulations coming into force during 2019 and 2020.
Cummins Stage V range works to Hardi’s requirements for a compact design, high fuel efficiency and in-field performance. Top-rated power for Cummins Stage V B6.7 has increased by 30 percent compared to its Stage IV predecessor. Additionally, peak power for L9 increased from 298 kW (400 hp) to 321 kW (430 hp), along with a 13 percent increase in peak torque.
“The higher power and torque of our Stage V range paves the way for higher machine capability and increased productivity, which we know is key for Hardi’s customers. The Exhaust Gas Recirculation (EGR)-free design reduces complexity, making the integration process simpler, and its fewer parts make maintenance easier – ultimately lowering total cost of ownership for farmers.” explains Laurent di Vito, Engine Sales Manager, Cummins France.
Cummins will tailor engine power and torque curves to the specific operational needs of seven products, using in-house technologies such as turbocharging and exhaust aftertreatment. The new Single Module™ aftertreatment system on the B4.5, B6.7 and L9 Stage V engines is 30 percent lighter and 50 percent smaller than Cummins previous system, reducing overall space claim.
In addition to Stage V products, Cummins will continue to deliver Stage 3A QSB4.5, QSB6.7 and QSL9 engines for equipment running in lesser emission regulated regions such as Australia and Russia.
“We were looking for an engine range that could meet our needs for performance and fuel efficiency, as well as be flexible enough to power our sprayers at Stage 3A and Stage V. One fit and one space claim – and Cummins can provide this. Not only does this reduce our work at the integration stage, but it also enables us to provide products to meet a range of emissions standards,” Said Christophe Benoit, Product Director, Hardi.
Cummins has worked closely with Hardi to understand operational requirements, not only of equipment, but of end users too. Cummins engineers visited Hardi’s local team in Australia to fully analyze the duty cycle of sprayers in that region in order to develop engines specifically optimized to Hardi’s self-propelled sprayer range.
“A partnership approach has been a key factor in the success of this project. Cummins listened to our requirements and our future vision, which gave us confidence in their ability to supply engines that perform for our customers, wherever they are in the world.” concludes Mr Benoit.
The first Stage V engines will be delivered to Hardi from Cummins UK manufacturing plant in Darlington during Quarter 3, 2018, and follows on from the supply of Cummins QSB4.5, QSB6.7 and L9 Stage 3A engines for Hardi’s Alpha, Saritor and Rubicon sprayers.
