A THIRD model has been added to Case IH's Optum range – the 250 CVX will be the entry-level machine at 250hp.

It sits below the 270CVX and 300CVX models with their nomenclature reflecting their nominal power output, though the 250 has an engine management boost which takes it to 273hp when under load.

Like the others it comes as standard with the CVXDrive continuously-variable transmission it is also available with a number of optional features so that customers can tailor-make their tractor.

The range’s combination of power and compact dimensions continues as it has the same 2.995m wheelbase as the others in the range. Though this range is relatively lightweight, the chassis is designed to be ballasted when needed for heavy duty cultivation work, for instance.

Like its siblings, the new Optum is built around a heavy-duty front axle and a structural engine oil sump for the 6.7-litre FPT Hi-eSCR Stage IV six-cylinder engine. That's a de-tuned version of the same turbocharged and intercooled unit in the existing Optums.

Fuel-saving features include an idle speed management system, which reduces engine speed from 850rpm to 650rpm if the tractor remains still without moving for two minutes.

On the options list are anti-lock braking (ABS) and an engine braking system. That latter feature works in combination with a variable-pitch fan to create a unique solution in the tractor industry to the requirement for high braking efficiency, providing up to 149kW of braking power to rapidly reduce tractor speed and stop the vehicle quickly and efficiently, making it ideal for transport work.

Its category IIIN rear linkage can lift up to 11.058 tonnes, with a figure of 10,305kg throughout the lift range. Hydraulics are powered by a 165 litre/minute pressure flow compensating pump.
