Machinery: Deere's newest range
Bruce Lett looks at some of the new tractors and combines about to get going in the fields
John Deere has unveiled new 6R and 7R models, in order to compliment its 8R Series tractors, which were launched earlier this year. The new models were designed to meet European Stage IIIB emissions regulations.
The company has also introduced new combines, the W, T and S-Series for the 2012 season.
The new, top-of-the- range S690, it claims, features the most powerful engine available in a combine today at 625hp. Finally, at the top end of the trailed sprayer range is the new R962i, which has a capacity of 6,200 litres.
For the moment though, it is the tractors that will interest most, and like many other manufacturers in the industry, Deere took the opportunity to completely revamp its ranges, in tandem with the introduction of new emissionised power plants. The firm has reaffirmed its position on exhaust emission control across the 6R and 7R ranges and, like fellow US firm Cummins, has shied away from SCR (AdBlue), which is more popular with manufacturers on this side of the Atlantic.
Already in use on the 8R series, Deere uses a combination of cooled EGR -- Exhaust Gas Recirculation -- variable geometry turbos and an exhaust filter that contains a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF) to scrub their exhaust gasses. The advantage of this system, as Deere would be the first to point out, is that its products are 'diesel-only'.
Perhaps the most popular John Deere range in Ireland is the 6000 series. In fact, with more than 550,000 units having been produced by the Mannheim factory since 1992, John Deere makes the claim that the 6000 Series is in fact Europe's most successful tractor range.
Initially, three large frame models will be available. The new 6170R, 6190R and 6210R models will all with be equipped with Deere Stage IIIB 6.8-litre six-cylinder PowerTech PVX engines. The three models are rated from 170 to 210hp, which rises to a maximum of 200 to 240hp with Intelligent Power Management (power-boost).
