The Kverneland Qualidisc 21000T trailed compact disc harrow has a working width of 12.25m.
Taking up a considerable portion of the Power Farming site at the recent South Island Agricultural Field Days near Christchurch, the Kverneland Qualidisc 21000T trailed compact disc harrow, the first sold in the southern hemisphere, has a working width of 12.25m.
Said to be suitable for cultivation from 3 to 15cm, the unit can also be used for seedbed preparation after ploughing.
The machine layout has four independently mounted frame segments, with pressure on each segment adjusted pair-bypair via the Ground Contour System to ensure a constant pressure across the full working width.
Turning at the headland is achieved by the four swivelling front wheels of 400-60R 15.5, working in collaboration with the rear roller assembly, meaning despite its large working width, the machine turns tightly on 560 or 710 section oversized transport wheels.
Designed for use with prime movers from 350 to 650+hp, working at typical speeds of 10-15km/ h, with higher speeds creating a “boiling effect” of the soil around the discs, the unit weighing around 14.8 tonnes, is capable of high daily outputs.
The 600mm diameter conical discs are 6mm thick and heat treated, with an operating weight of up to 150kg/disc, to help ensure a full cut and thorough incorporation of debris or catch crops.
Designed to maintain a constant working angle, the discs are mounted on angled arms, each fitted with a large maintenancefree double ball bearing and 35mm axle. Special protection to the sides of the arm is achieved by a special 5-lip seal and the bearing protection joint, while the opposite side features a dust preventing O-ring assembly.
Working depth is achieved via two scales, mounted on the forward gauge wheels and the rear roller, adjusted separately to maintain the balance between the two rows of discs.
Depth adjustment is controlled hydraulically from the cab, allowing prompt changes as field conditions vary.
Final consolidation is achieved with either the 560mm diameter Actipack roller said to be suited to medium to heavy soils or the Actipress option, which features a twin roller layout, offering greater carrying capacity in lighter conditions.
Tractor connections require two double and one single acting outlet, the latter to raise and lower the transport wheels, one double acting supply for pressure adjustment and the other to fold the machine to its 2.95m transport width.
Massey Ferguson has announced a strategic supply partnership with International Tractors Limited (ITL), a manufacturer of low-horsepower and compact tractors, with recognised brands such as Sonalika and Sollis, to expand its portfolio with a new tractor range.
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.
