Wide harrow helps cover more ground

Cultivation and seeding specialist LEMKEN has topped off its Rubin compact disc harrow range with massive ten-metre working width.

Like the smaller Rubin 10 models offered up to seven metres wide, the new Rubin 10/1000 offers a symmetrical disc arrangement for fuel-efficient operation without side draft.

Up front, hitching to the tractor uses a ball coupling or drawbar eye. Ease of attachment and removal is aided with the addition of a hydraulic support stand.

The two rows of 645mm diameter serrated concave discs allow a thorough incorporation across the full surface width from a soil depth of only seven centimetres. A 14cm spacing between the discs helps ensures blockage-free work, even when operating in stubbles with high volumes of organic matter.

Each disc is equipped with a coil spring overload protection with damped kickback, helping to reduce shock loadings on the main implement frame.

Clever design details across the working sections feature a pendulum type suspension to ensure optimal following of the field contour. On very uneven terrain, or when working on slopes, the optional iQ-Contour pendulum compensation guarantees optimum surface adaptation.

In addition, the hydraulic depth adjustment makes it possible to respond to changing conditions and the working depth can be changed on the move.

For transport between job sites, the machine is folded from the cab. The rear rollers patented folding system ensures a three-metre transport and a height of only four metres.

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.
