Case IH has announced changes for the 2015 Magnum tractor range which will meet European Stage IV exhaust emission regulations and will be fitted with a CVX transmission. From late 2015 there will also be the further option of new Rowtrac rubber track drive on the rear.

The Magnum models will span the power range from 250hp to 380hp across five models. The range is powered by an 8.7 litre Cursor 9 engine from Fiat Power Train (FTP) Industrial. The engine is equipped with the Hi-eSCR system and meets European Stage IV (Tier 4 Final) exhaust emission regulations.

Case IH claims that the Hi-eSCR system is a further development of the SCR solution used for Stage IIIB. The company says the SCR solution has proven successful with simplicity of design, great fuel efficiency and with a best-in-class engine oil change interval of 600 hours.

On all models except the Magnum 250, the wastegate turbocharger is replaced by an eVGT, an electronically variable geometry turbocharger. This is said to help the engine power and torque characteristics at lower engine speeds with a peak torque of 1,850Nm between 1,300rpm and 1,400rpm on the Magnum 380 model.

New transmission

The new Magnum range will offer a range of transmission options including Full Power Shift and CVX in both 40 ECO and 50km/hr versions. This new Magnum CVX transmission has four mechanical ranges.

The system allows for 50km/hr at 1,400 rpm with the aim of reducing costs during transport operations. The 2015 Magnum models include the Automatic Productivity Management (APM) used on other Case IH CVX tractors with the dual-hand throttle to allow the operator to set minimum and maximum engine speeds.

The Magnum CVX transmission is said to have a seamless power transfer from 0 to 50km/hr without the need of a lever or switch. The operator can also pre-set three adjustable target speeds within this speed range to set the optimum speed for a given operation.

Active Hold Control, a feature that prevents the tractor from rolling back when stopping on a hill, is also included. It allows for pulling away again without having to use clutch or brakes. The Headland Management Control (HMC) allows the operator to record headland functions, to make repetitive field applications as efficient as possible.

The Magnum has a new roof design with an increased number of working lights. In addition, the engine air intake system has been relocated to the left-hand cab A-post area which claims to give better air cleaning performance in dusty environments. This is because the air at the top left corner of the cab is the most dust- and dirt-free due to engine cooling fan dynamics.

Other more subtle changes include new fuel and DEF tanks with padlock-type caps that have been styled into the tractor design. On the right, the steps have been moulded into the fuel tank for ease of access to clean the cab windows. Integrated handrails are included for support and stability on the platform covering the right tank.

The internal cab changes include an improved 360° lighting package with 14 LED and three HID placed working lights which are said to increase the lighting capacity by 60% for night-time operations. There is a new high-end leather seating option with both heating and ventilation which is coupled to an updated Multicontroller with improved comfort and backlit buttons.

Spacious

Case IH says the cab is more spacious and has a larger glass area. Case IH claims that the new Magnum range, with a cab noise level of 67 dBA, has the lowest cab noise level. This is complemented by an integrated Bluetooth radio.

The Magnum has a five-point suspension package. The front axle suspension, with 100mm of travel, is designed to keep all the tyres on the ground for stability and efficient performance. The cab suspension reduces vibration, and stabilises the cab front-to-back as well as up-and-down.

Five cab suspension settings are available and a semi-active seat automatically controls the damping of the seat inside the cab. Further suspension is provided when carrying implements on the road by a ride accumulator for the front linkage and automatically on the rear linkage.

The Magnum will be available with the integrated AccuGuide automated guidance system. This takes the correction information from the 372 antenna compatible with both GLONASS/GPS satellite systems.

AFS Connect Telematics will be available as an optional kit and uses a combination of global positioning system and mobile phone technology to send and receive machine, agronomic and job-site information.

Rowtrac innovation

The Magnum Rowtrac builds on the bigger Quadtrac tractor experience and uses a combination of a suspended wheel-type front axle with rear-axle tracks. This system means differential locks can still be engaged when additional traction is required.

There will be several track belt options available including 16”, 18”, 24 and 30” which can be fitted on a machine for 76”, 80”, 88”, and 120” row spacings. Case IH says that with the suspended front axle with four contact points on the ground, there is less forward/rearward roll compared to some other tracked machines.
