The tractor power “arms race” cranked up a notch at the Farm Progress Show in the US, where Case IH unveiled its latest addition to the Steiger Quadtrac line-up.

Building on the Quadtrac 715, which in Britain carries a list price of £754,000 plus some loose change, the newcomer extracts 853hp from its 16-litre FPT Cursor engine, as near as damn it 10% up on the 715’s 778hp.

Like its lesser-powered sibling, the Quadtrac 785 delivers its power and torque through the 16-speed full powershift PowerDrive transmission, and the new Heavy-Duty track assembly design, which has a longer wheelbase and 6% larger footprint than earlier iterations.

The track system also features dual axis hydraulic suspension for the three track rollers to help keep the traction belts in firm contact with the field surface for maximum grip and improved ride quality.

There’s no word yet on whether it will come to Britain.
