John Deere unveiled what it is calling a completely new 6M Series tractor range at Agritechnica. The new series will replace the previous 6M, 6MC and 6RC series. The range includes four new four-cylinder models from 90 to 120hp which have a 2.4m wheelbase. This is a smaller-framed tractor than what was previously offered. It has a tidy low bonnet design, a slimmer steering wheel cowl and the new panoramic window in the cab roof. The short wheelbase means the new models have a tight turning circle of 4.35m. These tractors have a maximum permissible weight of 10.45t. The four new four-cylinder models are powered by a 4.5-litre John Deere engine. Three different gearbox options are now available – four-step powershift PowrQuad, AutoQuad and CommandQuad Plus, which is a fully automatic gear and range shifting gearbox.
