Dual mower combinations offer increased output and better utilisation of tractors.

Triple 'butterfly' or dual mower combinations have become increasingly popular, offering increased output and better utilisation of tractors that keep gaining horsepower.

Working in straight runs and sufficient overlap between the front and rear mowing units, missed crop is not usually a problem, but during turns and depending on the length of the combination, strips can often be missed, leaving what is often described as a Mohican finish.

Seeking to deliver optimum tracking on turns, reduce losses and offer precision without time-consuming adjustments, Pottinger has launched new automatic curved side shifting on the Novacat F 3100 mower.

This side shift system on the front mower guarantees a perfect overlap with the rear mower and ensures the tractor drives along a clear track free of forage when cornering and working on steep ground. The curved arc of movement means that the entire working width of the cutter bars can be used at all times, offering maximum productivity, unlike competitive solutions that use straightline side shift solutions, which can still leave several centimetres of crop remaining uncut.

In operation, should the tractor drift sideways when cornering or on steep terrain, the rear tyre of the tractor does not run over uncut grass because the mower shifts towards the inner radius of the curve, ensuring that no forage is left uncut, as the front mower overlaps perfectly with the rear unit.

The system works via its ability to detect the changing degrees of overlap between the front mower and the tractor or rear mower(s) and respond automatically. Automatic mode allows the operator to concentrate on their surroundings and driving the tractor, with the added advantage of fewer turning manoeuvres to “tidy up”, meaning there is less damage to the sward and the ground.

An optional ISOBUS automation package controls the side shift of the mower automatically, depending on the turning angle of the tractor or the inclination of the slope to the left or right. This means that the driver’s workload is significantly reduced because no intervention is required.

Case IH Wins EIMA Award for Optum Suspension System

With the biannual Italian EIMA machinery Expo less than a month away, Case IH has taken out a Technical Evolution award for the Advanced Vehicle Suspension system available on its Optum 360–440 series tractors.

The Advanced Vehicle Suspension system, available on Optum 360, 390, and 440 models, responds to changing conditions, automatically adjusting how the suspension reacts to absorbs shocks and controlling vehicle movement.

In operation, sensors monitor the vibrations transmitted from the tractor chassis to the operator cabin, allowing the system to adjust suspension damping in real time. The control system incorporates key priorities, such as comfort at lower speeds and stability as speed increases, while also reacting to factors such as lower tyre pressures, where the tyres absorb more of the initial shock.

Case IH said as suspension requirements change throughout the working day, as tractors move between the paddock and road transport, the system manages suspension response in the background as tasks, speeds and conditions change, leaving the operator without the need to make manual adjustments.

Richard Hollins, Optum series tractors global product manager, said: “Pioneering technology must earn its place in the working day. Farmers and contractors will judge an investment by what it delivers, including manageable ownership costs, dependable up-time and the versatility to tackle different jobs. With AVS, we are putting intelligent control to work for comfort and stability, without giving the operator another setting to manage.”

Organised by FederUnacoma, the Italian Agricultural Machinery Manufacturers Federation, the contest has been part of EIMA since 1986, with the Technical Evolution distinction awarded to products that introduce original improvements to solutions already manufactured or patented.
