Rear discharge spreaders offer precision application

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.”
