John Deere shows all-new line-up

And the company has not been slumbering. It had more than 100 new products on display, ranging from a 625hp combine to a robot lawnmower.

The key highlights for UK farmers and contractors? The 6R tractors, which replace the 6030 models, were probably the biggest news, although bigger farmers may be more interested in the fact that the 7030 tractors have been replaced by the 7R series.

On the harvesting front, Deere has gone through its entire three-range combine line-up to offer machines that should give rivals a run for their money. Finally, there were new sprayers and big balers too.

The 6000 series has been the firm's best seller for many years, with more than 550,000 tractors rolling out of the Mannheim factory in Germany since its launch in 1992.

The new range (which replaces the current 6030 models) will go from 105hp right up to 210hp, and divides into small-frame tractors up to 125hp, mid-frame up to 150hp and large-frame ones going from 170hp to 210hp.

There are three wheelbases, too, going from 2.58m up to 2.8m and with scope to fit chunky 205cm diameter tyres on the bigger machines..

All tractor launches these days involve fitting new engines that meet the increasingly tough emissions regulations. The 6Rs are no exception, with 6.8 litre PowerTech PVX powerplants that meet the latest Stage IIIB regs.

As ever, they are what Deere calls "one-fluid" tractors. This means they use exhaust gas recirculation to reduce their emissions rather than the SCR system used by most other makers, which involves having a small secondary tank of urea to do the job.

Three models will be available initially: the 6170R, 6190R and top-of-the-range 6210R, with the rest arriving the following year.

Incidentally, the latter's 210hp makes it the biggest tractor ever produced by the Mannheim factory. It also packs more horsepower than the 9.5t 7830 model, despite weighing 1.5t less.

All models also have Deere's IPM boost system that gives them 30hp more for transport or pto jobs.

The range gets a new ComfortView cab which is bigger (and has more glass) than its predecessors. A 7in colour screen comes as standard and a GreenStar 2630 touchscreen is an option.
