Watch: Upgraded Case articulated tracked tractors

Case IH has launched its first high-horsepower articulated tracked tractors available with continuously-variable transmission technology.

It says the new upgrades enhance fuel efficiency through ability to operate at lowest engine rpm for the task in hand and boosts work efficiency through faster attainment of intended working speed.

Case says the move is designed to bring the benefits of improved fuel efficiency, ease of operation and reduced operator fatigue to the highest horsepower sector of the tractor market.

New for 2017 is a range of three Case IH Quadtrac CVX models which will complement the existing line of five models with the established standard powershift machines.

The new CVXDrive transmission offers the advantages of stepless travel from standstill up to 40 km/h, and can be operated to work at a desired forward speed or engine speed, with Automatic Productivity Management software then able to adjust engine and transmission management accordingly, according to Hans-Werner Eder, Case IH Quadtrac product marketing manager.

“At 613 peak horsepower, the 540 CVX, which is the flagship in the Quadtrac CVX range, offers the highest available power of any CVT tractor,” he said.

“The other models in the range are the Quadtrac 500 CVX and Quadtrac 470 CVX, which have respective maximum power outputs of 558hp and 525hp.

Case IH Quadtrac CVX tractors are powered by electronically-controlled 12.9L cursor 13 six-cylinder engines from sister company FPT Industrial, with a single-stage turbocharger on the two smaller tractors and a two-stage turbocharger in the 540 model.

The engines meet Stage IV emissions legislation through the use of the Case IH Hi-eSCR system, which also ensures that fuel efficiency is optimised.

Continuously-variable transmissions have, until now, never been available in an articulated tracked tractor.

Now, full power availability at low ground speeds for special applications/implements, and full hydraulic flow availability at low ground speeds, for applications such as drilling/planting is available on the tractors. The result is increased productivity with faster cycle times and maximum fuel efficiency.

The range also provides stepless travel from 0-40km/h, and 0-18km/h in reverse.

The hydrostatic pump and hydrostatic motor are a single unit, with no high-pressure pipes between pump and motor. A variable swash plate on the pump creates different speeds and allows the fixed hydrostatic motor to be operated in both directions.

Active Hold Control means the tractor, when brought to a halt on a hill, can remain static without the operator applying foot or hand brake.

In place of the foot throttle found on Quadtrac tractors with powershift transmission, Quadtrac CVX models are fitted with a drive pedal.

Maximum ground speed can be adjusted with the thumbwheel and speed range buttons on the armrest-mounted Multicontroller. In manual mode, the foot pedal acts as a conventional foot throttle. The Multicontroller also incorporates a power shuttle switch, which works in parallel with the shuttle lever on the left of the steering column, for convenient direction changes whichever way the operator desires without releasing the steering wheel.
