Rear discharge spreaders offer precision application

The humble muck-spreader has evolved into the technological age, with UK-built Bunning rear discharge spreaders offering a range of options to suit today’s precision farming requirements.

For exceptional accuracy of application, the Topcon ISOCAN variable rate controller features live 20 tonne weigh-cells positioned on the spreader chassis and drawbar. This allows the operator can see the exact weight in the machine, and that of the product that has already been spread.

Forward speed is monitored via a GPS receiver, while working width is entered by the operator, although usually governed by the type and consistency of the material being spread. From this point, the operator enters a target spreading rate in tonnes per hectare, from where the computer will vary the spreader floor speed to achieve the desired application rate.

The control system can be via a supplied RDS Topcon monitor, or a tractor’s own ISOBUS screen. If section control is unlocked on the tractor, the spreader is also able to switch itself off, should the tractor travel across an area that already has been spread.

For those wanting to undertake precision farming with variable application rates, a pre-defined application map can be loaded via a USB connection. Data can be logged and exported via USB and can be viewed as an Excel spreadsheet.

Hastings-based Bostock New Zealand purchased a Bunning Lowlander 150 wide-body model featuring twin, large diameter vertical augers combined with large spinner discs. The machine also features a removable rear canopy which ensures wide and even spread of fine material such as chicken litter, but it can also be removed to deal with heavy, wet material such as drain cleanings.

Bostock’s Andrew Meulli says they are very satisfied with the performance of the new muck spreader. “It has massively increased our productivity and efficiency within our spreading program.

“The spread rate is relatively accurate across our range from 5 t/ha to 20 t /ha and across 3 different products. Downtime has only been one shear-bolt and a loader tractor window to report at this stage.”

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.
