John Deere has said it will lead European customers seamlessly through the upcoming transition from Stage IV to anticipated Stage V regulations as the current line-up of John Deere engines equipped with DPF technology are all Stage V capable.

One of the significant impacts of Stage V will be the introduction of a particle number (PN) limit for engines in the 19kW to 560kW power band and this will necessitate use of DPF technology by manufacturers, argued John Deere.

A spokesman said it had been using DPF technology since Stage IIIB and that more than 150m DPF hours have been logged in the field.

"Our extensive experience with the development and integration of DPF technology means John Deere is already capable of complying with the requirements indicated in the EU Commission's proposal COM (2014) 581 concerning Stage V emissions," pointed out Geoff Stigler, director of sales, marketing and customer support in EAME, Asia and Australia for John Deere Power Systems.

He argued that this confirmed the route chosen by John Deere for Stage IV is the right one and that other manufacturers will have significant 'complexity' in complying with the Stage V regulations.
