UPGRADED Maxxum tractors from Case-IH will be launched into the UK featuring a new 24 x24 semi powershift transmission which provides eight powershift steps in each of the three ranges.

The ActiveDrive 8 covers speed up to 10.2kph and is designed to handle heavier draft work in range one, with additional creep speeds available. Range two covers nearly 90% of the field, grassland and loader requirements from 1.6kph to 18.1kph.

For road travel, the transmission is designed to start in range three, and a skip-shift function allows quick progress through the powershift speeds, while an auto shift feature allows the tractor to progress automatically through any set of eight speeds in the field, and through all 16 gears in the top two ranges on the road.

Smaller, highly manoeuvrable Farmall A tractors with low running costs have also been introduced by Case-IH which come in three models ranging from 55hp to 75hp using 2.9litre turbocharged/intercooled engines with 12x12 or 20x20 creep Mech-Shuttle or powershuttle transmissions.

All models feature a Case IH front axle which is three-point linkage and loader-ready, enabling these to be fitted quickly and easily. The rear axle, which has a maximum capacity of 3700kg, incorporates a mechanically-engaged differential lock and oil-immersed disc brakes, while the standard hydraulic trailer braking system provides excellent performance, but a pneumatic system can be specified.

The rear three-point linkage sets a benchmark for this class of tractor, providing a maximum lift capacity of 3000kg when an assister ram is fitted. Farmall A models also feature a fully-independent 540rpm, six-spline PTO, with the option of 540/540E and 540/540E plus ground speed units.

Also new to the Case range is lower spec 'X' versions of three Puma tractors which feature in the 140-165hp bracket. While the tractors are built around a light rear axle, many of the key changes can be found in the cab, with a basic operator interface with simple digital information display, a base seat offering, and no rear wiper. The cab itself has been equipped with features likely to appeal to livestock farmers, including a low-profile roof to aid access into buildings, and an opening right-hand door in addition to that on the left side of the tractor.

At the rear, the mechanical remote valves are non-configurable, while the rear wheels are fitted with narrow fender extensions. A two-speed 540/1000rpm PTO package is standard, while a comprehensive lighting package, with four halogen roof-mounted work lights, is retained.

A full list of options allows the new Puma X models to be equipped with additional features as required, including guidance and auto-steering systems, together with the recently-introduced adaptive steering system which allows the number of lock-to-lock steering wheel turns to be altered according to the work in hand. Also on the options list is a mechanical cab suspension system.
