Manufactured by a local family-run company Roesner there is a 124-year history behind the innovations of the top selling Marshall Multispread spreader brand
The manufacturer of Marshall Multispread, Roesner, was founded by Arthur E Roesner and has been in operation since 1900 in Harvey Western Australia.
The foundation of the Multispread development is part of small-town folklore with an ingenuity that has propelled the line into our top-selling spreader brand.
In 1956, Arthur’s son Roy was approached by Arthur Marshall to build a prototype fertiliser spreader, and by 1961, the first sales of the Marshall spreader were made to fertiliser company, CSBP.
Today, it’s still a family business with Managing Director Jeffrey Roesner at the helm, the grandson of founder Arthur Roesner, and Jeff’s two sons, Matthew and Mark, are also part of the business.
Over 11,000 Marshall Multispread models are at work across the breadth of the country with the choice of two popular trailed model ranges.
The 800-Series offering product capacities of 2.5 to 14.0 tonnes, with spread widths from 28 to 36 metres.
While the 900-Series has product capacities of 4.5 to 16.0 tonnes, and spread widths from 32 to 36 metres
Innovation has been a major focus
The Marshall Multispread performance has benefited from continuous innovation, with a prime example being the i4M spreader controller, originally released in 2017.
With the launch of Version 3 in June 2025, this controller has proved the most popular with farmers. It enables a cost-effective solution for variable rate spreading, machine auto-shut off and coverage mapping. The Version 3 system also includes an updated auto-calibration function.
The auto-calibration function works by taking high-speed readings from the spreader loadcell’s as the machine is moving across the paddock.
If the calibration factor changes due to fertiliser properties such as moisture content or bulk density, the controller will detect the change from the loadcell readings and compensate accordingly.
Instead of waiting until the end of the load to detect the calibration factor error, the controller will immediately adjust to ensure the correct application rate is applied.
“There is no need to carry out a catch test, as the i4M control will automatically determine the fertiliser calibration factor when the spreader starts work,” Matt Roesner confirmed.
D3 Spinner can be retrofitted to more recent models
Launched in 2022, the D3 spinner system has been independently verified by the Kondinin Group based on the industry standard ACCUSpread testing procedure.
Spread widths up to 36m for Urea and 12m for lime were recorded using the D3 setup.
The D3 spinner system is the result of three years’ detailed research and development, designed and tested in a range of different paddock conditions.
The D3 design incorporates a redesigned chute with individual deflectors for granular and non-granulated materials, which ensures accurate placement of the fertiliser onto the spinner disc.
When spreading granular products, a plastic cone is bolted to the centre of the disc to better control the dropzone and prevent re-circulation of particles on the spinner disc.
The D3 granular fertiliser vanes have been redesigned using computer-based simulations, factory and paddock testing. There are four vane positions to enable fine-tuning of the distribution pattern.
Over the past three seasons, Roesner’s engineering team have undertaken paddock testing across Western Australia with the D3 system to better understand its performance in real-world conditions and with different types of fertilisers.
These test results are available from the manufacturer Roesner Pty Ltd, or through your local Multispread dealer.
Aside from the spinner upgrade, test kits are now available to provide confidence of machine performance in the paddock.
The paddock test kit consists of a set of plastic test trays that capture the fertiliser as the spreader traverses over them.
The fertiliser is collected and placed in a set of test tubes for visual inspection. The paddock test kits are a valuable tool for ensuring the correct spinner setup and understanding fertiliser variability.
The D3 system is available as a retrofit kit for Multispread machines manufactured after 2012. To check the compatibility of your existing spreader, contact Roesner Pty Ltd here or your local Multispread dealer here.
