Mower conditioners get a revamp

French machinery manufacturer Kuhn has expanded its range of mower-conditioners fitted with rollertype conditioners, with the addition of the new trailed FC 3155 TLR and FC 3555 TLR models.

These have working widths of 3.10m and 3.50m respectively.

The side-pull drawbar units, with hydraulically offset mowing elements, feature Kuhn’s SquareFlex roller conditioners that incorporate mechanically driven 240mm diameter rollers that are claimed to be synchronized for life.

The unique profile of the polyurethane rollers ensures that plants and stalks are crimped, irrespective of the direction the crop is presented.

Driven by a gearbox to rotate at 780rpm, the pressure exerted by the rollers is easily adjusted, while also allowing them to move apart to allow foreign objects to pass through.

The layout is said to be suited to dealing with crops such as alfalfa, clover and lucerne or any crops where there is a risk of leaf shatter or those with thicker stems.

Both models are fitted with the Opti- Disc Elite cutter bar, fitted with the Protecta- Drive safety system that, when an impact occurs, sees the shaft above the bearing “shear” through a pre-determined groove to allow the disc to freewheel and protect the gear train.

The “sealed for life” cutter-bar requires no maintenance and is equipped with large diameter gear assemblies and double-row angular contact ball bearings for robustness and durability.

Equipped as standard with the Fast- Fit quick knife release system, a leaf spring layout ensures that there is constant pressure on the blade securing pin, with rapid change of any blunt or damaged blades.

A spring suspension system ensures efficient ground pressure reduction of the mower unit while also ensuring positive ground contour adaptation.

The clever Gyrodine headstock ensures that the PTO input shaft remains straight when undertaking tight turns, allowing the machine to manoeuvre tightly in narrow plots or irregularshaped paddocks.

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.
