Case IH this year launched a new generation of Magnum tractors designed to offer more power, comfort and fuel economy. Nine models, ranging from 150 to 280 PTO hp, are powered by 6.7- or 8.7-liter Interim Tier 4 engines made in-house by Fiat Powertrain Technologies. The engines are the first to meet Interim Tier 4 standards using Selective Catalytic Reduction (SCR) emissions reduction technology, which the company claims cuts operating costs by 10% through increased fuel efficiency and extended service intervals, now at 600 hrs.

The new engines are designed to deliver up to 14% power growth before peaking out. An additional 35-hp “power boost” kicks in during mobile PTO, hydraulic and transport applications. A transmission feature called Diesel Saver Automatic Productivity Management, carried over from the previous line, determines the best gear ratio and engine rpm for the task to maximize fuel efficiency.

A new MultiControl Armrest gives drivers fingertip control of engine throttle, up/down shift, forward/reverse shuttle, hydraulic remote valves, and an automatic end-of-row function. Cab suspension was added for the first time. A new surround frame allows for a turning radius of just over 16 ft., the tightest in the industry. Hydraulic flow also is industry-leading at 75 gpm.
