Tedder stays wide, folds smarter

Kuhn claims its latest 13m wide tedder can be folded and ready for transport in 25 seconds – about half the time taken by its predecessor. Kuhn claims its latest 13m wide tedder can be folded and ready for transport in 25 seconds – about half the time taken by its predecessor.

Machines with wider working widths have become a lot more common on the farm, particularly in the grass and hay production arena, where oversized rakes and tedders have helped to increase daily output dramatically.

In many cases the size of the machines dictate that they have complex hydraulic and mechanical systems to fold the machines from transport to work and back, while also eating up a surprising amount of time.

Grassland specialist Kuhn has addressed this latter issue with a redesign of its latest 13m wide tedder, allowing it to be ready for transport in 25 seconds – said to be about half the time taken by its predecessor.

The machine features a new single-movement folding mechanism which works directly off a tractor spool valve without needing any control box or electronic sensors.

Transport and storage are also improved thanks to a reduction in length to 6m, while a reversible drawbar allows it to be hitched to a greater variety of tractors.

 The GF 13003T replaces the outgoing GF 1301 and offers operators improvements centred around new rotors, tines and the fast-fold system.

Still equipped with 12 rotors like the previous machine, internal upgrades are said to reduce wear, while the mounting system and improved contour following characteristics is said to reduce the

risk of soil  contamination.

New 10mm diameter tines are equipped with springs that have increased from 70mm to 80mm diameter, that work in conjunction with an anti-tine loss system and hydraulic tine height adjustment to effectively double the expected lifespan of the previous tine format. 

In operation, the weight of the chassis is supported by large transport wheels, while the small diameter rotors are suspended separately on individual wheel equipment, enabling each rotor to adapt to the ground contours, meaning soil contamination is reduced and tine tip wear is less severe.

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.
