The aim of this project was to work with growers to maximise harvester throughput capacity with acceptable losses in the Western region and compare data to that collected in 2022.
The harvest losses measured in 2022 are largely consistent with results from 2021 over the full spectrum of results with sufficient depth of data from which conclusions can be drawn.
Front losses continue to be a significant contributing factor to losses in the harvesting process. Stripper fronts have again demonstrated significantly higher levels of loss which could be partly offset by the increased capacity of the harvester.
The need for all growers to embrace drop trays is demonstrated in the 2021 data and reinforced in the 2022 data. Growers using trays had significantly lower losses simply by using trays for quantification, calibration of loss sensors and iterative investigation to address the source of losses.
Determining the best path to minimise losses whilst maintaining capacity requires continuing education of operators, trainers and in some cases, manufacturers. But this training would be more effective if supported by independent research to quantify the potential benefits of, for example, threshing component modifications.
Modifications to the machine threshing components should be investigated further and quantified for a cross-section of modifications, harvesters and crop types.
The economics of using a Vario/Varicut/Varifeed fronts pending crop type, area and value may assist growers in making decisions around the investment in a second front.
Port zone variations in yield are likely a symptom of a lack of data depth, but an ongoing investment in this work to add depth to the collected data may assist in identifying and filtering data.
With better than average crops harvested in the 2021 and 2022, it should be remembered that harvest loss figures in a lower yielding year may vary significantly in loss amount, source or geographic location to those found in this research.

The project was co-ordinated and led by the Grower Group Alliance with the research component managed by harvest expert Ben White. The project was also supported by Peter Broley of Primary Sales who provide Bushel Plus drop trays and training in their use. The on-ground measurements were conducted by three grower groups (Liebe Group, Corrigin Farm Improvement Group and Stirlings to Coast Farmers) and a private consultant in Esperance who measured harvest losses in 65 paddocks for 8 crop species. |
