John Deere’s drivetrain electrification
Deere’s drivetrain electrification is available to OEMs following 300,000hours of field experience with hybrid loaders.

A drivetrain electrification solution from 257 John Deere Power Systems is now available to OEMs, following extensive in-field testing on the company’s own construction equipment.

It announced the move at CONEXPO-CON/AGG, following several years and 300,000hours of in-field testing by customers operating its 644K hybrid wheeled loader. As a result, the firm is confident of the durability and performance offered by its hybrid powertrain solution, and that is backed up by the announcement of a 20,000hour warranty on electrical components on its larger 944k hybrid wheeled loader.

JDPS claims that the hybrid powertrain solution offers better controllability and finer management of power compared to traditional drivelines in wheeled loaders. In the 644K for example, an electric generator/pump drive produces 200kW of power, which is then fed into an inverter. Here, DC current is created and fed into an electric motor, which drives the loader’s powershift transmission.

This power supply process also includes hydraulic functions too, offering full flow capability and greater performance as a result. The hybrid drive has also meant a smaller 6.8litre engine can match the work of a 9litre engine.

Manufacturers push hybrid driveline technology

Driveline technology continues to develop rapidly, with many manufacturers at this year’s Conexpo exhibition showing Tier 4 Final emissions solutions, along with a host of fuel saving transmissions and hydraulic systems, all aiming to reduce operating costs for the customer. However, while there was certainly a hybrid presence at the show, things haven’t perhaps moved forward as fast as many had expected.
