Increasing daily bale output was a priority for Davidson Contracting and the key reason for the firm’s upgrading its NH BR 6090 baler to a New Holland RB125C combi at the start of last season.
The eight-model series includes five agricultural models, two scraper models and a 4WD track model. The line-up develops maximum outputs from 429 to 605 boosted horsepower in the range-topping T9.600 AC. It also uses the ZF developed CVT transmission already seen in the Case IH Quadtrac CVX Drive, which is configured to deliver at least 60% mechanical drive in all situations.
The Auto Command transmission provides seamless speed changes via the CommandGrip multifunction handle in the SideWinder II armrest, with integrated IntelliView IV ultra-wide colour touchscreen interface. The CommandGrip handle uses force-based logic to control the tractor’s speed and acceleration, working with the transmission to deliver a stepless range of speeds to exactly match the application.
Automated functions enable the operator to switch between three target speeds and four driving modes: Auto, Cruise, PTO and Manual, to optimise the task or fuel efficiency. In operation, the transmission adjusts engine power and ground speed for maximum productivity to match the work in hand; in transport mode the AC allows acceleration to 40km/h at 1650 engine rpm.
In PTO mode, speeds as low as 500m/hr can be achieved, which should suit the machine to heavy duty applications such as slurry injection, bed tilling or wood chipping.
The intuitive automatic control of engine power and ground speed, seamless speed adjustment and clutchless braking are said to dramatically reduce operator fatigue and boost productivity.
Auto Command also offers the maker’s Active Stop Start safety feature that prevents the tractor moving backwards or forwards when it is brought to a standstill, even with a heavy load, while also removing the risk of roll-back when stopping on steep inclines.
