Higher-powered versions of the New Holland T7HD and Case IH’s Optum have been introduced, with 340hp on tap and a peak torque figure of 1,353Nm at 1,400rpm.
The new models feature the same 6.7-litre, six-cylinder FPT engine as their 270hp and 300hp counterparts, but this has been tuned to deliver a higher output.
Unlike the smaller models there is no boost function, so full power is available at all times.

To deal with the extra firepower, both firms have upgraded the hydrostatic unit and control software in the CVT transmission – known as CVX Drive in the Case and Auto Command in the New Holland – as well as strengthening driveline components, the rear differential and rear pto.
Crucially, weight and proportions have stayed the same, meaning there’s little penalty for having the extra oomph.
Rear lift capacity also remains at 11,058kg, the front linkage can handle 6,016kg, and there’s the option of up to five rear and three mid-mount spool valves.
