Case IH to launch flagship Quadtrac CVX and new Puma models at LAMMA 2018

0

First public sighting of new models in the UK/ World’s most powerful tractor with continuously variable transmission/ Puma range gets entry-level models and upgrades, claim Case IH.

Complementing the five existing Quadtrac powershift models in the line-up, the three new Quadtrac CVX tractors are equipped with CVXDrive transmissions, which have, until now, never been available in an articulated tracked tractor. This offers the advantages of stepless travel from standstill up to 40 km/h and can be set to work at a desired forward speed or engine speed, the tractor’s Automatic Productivity Management software automatically adjusting the engine and transmission accordingly.

Producing up to 613hp, the Quadtrac 540 CVX is the world’s most powerful tractor with a CVT transmission, and is joined by the Quadtrac 500 CVX and Quadtrac 470 CVX models, which produce maximum power outputs of 558hp and 525hp respectively.

Case IH Quadtrac CVX tractors are powered by electronically-controlled 12.9-litre Cursor 13 six-cylinder engines from sister company FPT Industrial, a single-stage turbocharger being used on the two smaller tractors and a two-stage turbocharger in the 540 CVX. On this tractor, the smaller turbocharger delivers low-rpm responsiveness, while the second, larger unit provides maximum boost at high rpm. Each turbocharger has its own cooling system to provide 30 per cent faster response under load.

The engines meet Stage IV emissions legislation using the Case IH Hi-eSCR system, which also optimises fuel efficiency. On the largest Quadtrac 540 CVX, rated power (according to ECE R120 2) is 543hp, while Engine Power Management, introduced under load, takes this to 598hp, both measured at 2,100rpm rated engine speed. Maximum power of 613hp is achieved at 1,900rpm, and maximum torque of 2,607Nm at 1,400rpm. The tractor has a diesel tank capacity of 1,230 litres and a DEF (AdBlue) tank that holds 322 litres.

Case IH has also expanded its range of Puma tractors to include new entry-level models, while other Puma models have received significant updates for the 2018 model year.

Puma 140, 150 and 165 tractors are now available with a new ‘X’ base specification which offers an alternative for customers seeking a combination of high quality with simple features in the 140-165hp (rated) power bracket. Like other Puma models, the new tractors are built in the Case IH factory at St Valentin, Austria.

Featuring the Case IH six-step semi-powershift transmission, they will be identified simply by the ‘Puma X’ name, as distinct from the higher-specification Puma Multicontroller tractors with full and semi powershifts, and the Puma CVX models with the continuously-variable transmission. Respective rated powers of the tractors are 140hp, 150hp and 165hp, with maximum outputs, including Engine Power Management, of 175hp, 190hp and 210hp.
