THE qualities of continuously-variable transmission technology has been taken down the ‘food chain’ by Case IH, which is now fitting it to its Versum tractors which fit between the Luxxom and Maxxum ranges.

These four machines range between 100-140hp and will fit well with mixed farming operations tractors, while their new styling matches the larger Case IH models.

The new line’s models are the Versum 100 CVXDrive, Versum 110 CVXDrive, Versum 120 CVXDrive and Versum 130 CVXDrive – with each name indicating the rated horsepower at 2200rpm engine speed.

All CVXDrive models will come as as premium spec’ machines, and now mark the bottom end of where this transmission is offered. Previously, the smallest tractors fitted with it were the four-cylinder 116-145hp Maxxum line-up.

They use a 4.5-litre turbocharged and inter-cooled engine which meets EU Stage V emissions legislation through the latest development of the selective catalytic reduction (SCR) system from FPT Industrial, known as HI-eSCR2 – as fitted to some sister New Holland models.

This patented under-hood technology is an all-in-one after-treatment system assembly which also contains the diesel oxidation catalyst and diesel exhaust fluid (AdBlue) injector.

The CVXDrive transmission in the Versums provides stepless travel up to 40 km/h, a speed at which, using the Eco function, can be attained at reduced engine rpm. An electronic controller manages transmission operation for quicker speed change and fuel efficiency.

The incorporation of double clutch technology into the transmission means a smoother change and full tractive power available across the whole speed range.

Meanwhile, an active hold control feature allows the tractor to be stopped on hills and at road junctions without using the footbrake.

They all have automatic engine management, which automatically reduces engine speed, and thus fuel consumption, when it detects when less power is required. For example, when ploughing an area of lighter soil, or when demands on an implement’s hydraulic circuit are reduced.

The hydraulics use a closed-centre load-sensing (CCLS) pump, which means the oil circulates only when requested by the operator, and when more than one function is operated they do not affect each other.

A wide offering of mechanically and electronically-controlled hydraulic remote valves is also available up to seven outlets. Maximum flow rate is 110 litres/minute and they can be supplied loader-ready.

A new multi-functional front axle support frame means the optional front hitch and front pto can be fully integrated into the tractor.

And there’s quick coupler options for the front and rear three-point links. A front pto operates at 1000 rpm, while at the rear three speeds are available – 540/540E/1000 rpm, or optional 540E/1000/1000E rpm. A ground speed pto can also be ordered.

The four-pillar cab has a control layout similar to that used on larger models and the well-established Case IH Multicontroller armrest is fitted as standard.

Features in the highly-appointed low-noise cab include automatic climate control and a high-specification deluxe driver’s seat, while a 360° lighting arrangement completes the operator comfort package for long working days.
