Rake built for tramlines prevent soil compaction

The Swadro TC1570 four-rotor centredelivery rake is said to be an ideal fit for highways in paddocks. The Swadro TC1570 four-rotor centredelivery rake is said to be an ideal fit for highways in paddocks.

Controlled Traffic Farming (TCF) systems see arable operators, using tramlines as “highways” for moving through a crop.

Then, use machinery with specific operating widths to ensure there is no need to move off these tracks, thereby limiting compaction to the tramlines, rather than across the whole paddock.

While CTF has never really been used in dairy operations, German manufacturer Krone suggests this is changing as forward-thinking dairy farmers strive to limit compaction, particularly in wetter seasons.

The company suggests that with a maximum working width of 15.70m, the Swadro TC1570 four-rotor centredelivery rake is said to be an ideal fit for such operations.

Wider than the existing four-rotor TC1370, the V-frame concept on the newcomer is said to be an adapted version of the six-rotor TC2000.

Featuring 15 tine arms on each of the rotors, the mechanical driveline sees the front two rotors rotating about 25% faster than the rear units, which the company suggests promotes optimum forage flow through the machine to create tangle-free, box-shaped swaths. Operated via an ISObus terminal or in combination with an ISObus joystick, overall working width is adjusted by the two front rotor arms, while final swath wide of 1.40 to 2.90 metres is hydraulically adjusted via the rear pair of rotors.

The main frame can be lowered hydraulically to reduce the transport height to below 4.0m without the need to fold or remove any tine arms. The transport chassis is equipped with 710/40 R22.5 tyres as standard, or optional 800/35 R22.5 units, while infield stability is improved with the use of wide 16 x 9.50-8 tyres on the fourwheel rotor chassis’ and the 15/55-17 support wheels on the two front arms.

Electric height adjustment allows individual or simultaneous rotor adjustment, will the choice of two preselected heights to be saved on the terminal and activated at the touch of a button.

At headlands, the rotors can be set to lift just over existing swaths, while the lift delay of the rear rotors is also adjustable, and the automatic Soft- Down mechanism slows the speed of lowering just before the rotors touch down. Section control is also available to lift/lower the rotors automatically using GPS.

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.
