John Deere W540 – W660

German WTS combines were replaced in the autumn of 2007 by the W series. The technology remained largely the same. Two 5-bar and two 6-bar models were offered. The cutterbars were, as before, the length-adjustable 600R series, with ±4° header tilt standard. Behind the threshing drum there was a post-threshing drum and, on the straw walkers, a drum separator. An electrically adjustable sieve was available as an option; standard equipment included automatic adjustment of the threshing clearance and automatic regulation of both drum and fan speed. Instead of an elevator floor, there were screw conveyors that transfer the grain to the pre-cleaning sieves.

The 6-bar models were fitted with new 9.0-litre engines. Power was increased across all models, and as before an extra 17 hp was available during tank unloading. The W series was also offered in “i” versions, whose equipment package combined AutoTrac automatic steering, HarvestSmart threshing automation and the HarvestDoc yield-mapping system.

Just one year after its debut, changes were made to the cab. One of the four screens on the A-pillar was replaced by the CommandCenter control panel and display familiar from JD tractors.

For the 2011 season, the engines gained an extra-power feature during tank unloading. As an option, an electric push-button transmission was also made available.
