Baby Puma a short story
With its shorter wheel-base, the CVX is nimbler on its feet than bigger siblings, says Bruce Lett
CaseIH has just launched three new, short wheelbase models in the lower horsepower end of their Puma CVX range. Despite the fact they have just been launched, CaseIH will have one (a Puma CVX 160) at this year's National Ploughing Championships along with a 6088 Combine with 24ft header, Magnum 310, Puma 180, Maxxum 125 and JXU 115 with loader.
CaseIH is in the unusual situation that currently they are offering two completely different ranges of CVX tractor, one Fiat Power Train based and the other ZF/Sisu based. It is inevitable that the latter will be discontinued but when this will happen is not yet clear.
So what do the new Puma CVX models feature exactly?
The three new Puma CVX models are the Puma 130, 145 and 160. They have power ratings of 131hp, 146hp and 160hp respectively. With Power Management, these figures rise to a maximum of 171hp, 188hp and 203hp. The Engine Power Management system gives an increase in power of up to 22pc for transport or PTO work.
One of the most significant changes to be introduced (from 2011) on the new Puma CVXs is CaseIH's EfficientPower technology. This is essentially the addition of the Selective Catalytic Reduction (SCR) to the exhaust system of the tractor enabling the engine meet Tier 4 emission regulations.
All of the new models are powered by a 6.7-litre, six-cylinder, common-rail turbo-diesel engine and the SCR technology comes from parent company Fiat's truck wing, Iveco, where it has been successfully used for a number of years.
The upside to SCR technology is that it is more fuel efficient than the alternative 'emissionising', Exhaust Gas Recirculation (EGR) system. CaseIH are quoting a fuel saving of around 10pc with SCR and the EfficientPower technology compared to conventional engine technology.
