Glen Riethmuller

My role in the department

Glen conducts machinery research on broadscale crops, such as improving seeders, sprayers and harvesters. He is very interested in showing growers the benefits of a controlled traffic farming system.

Conservation of soil properties for maximum crop production is hard without controlled traffic due to the increasing weight of modern machinery. Glen believes autonomous vehicles have huge potential in agriculture to reduce dangerous tasks or skilled labour shortages.

Glen is currently the national chair of the Society for Engineering in Agriculture of Engineers Australia.

My background

Glen has more than 35 years experience in agricultural research on cereal and pulse crops in Western Australia. He is originally from a black soil farm near Toowoomba in Queensland where he completed his Agricultural Engineering degree. Glen went to the USA to complete a masters of science degree in Agricultural Engineering, and then on to Merredin for farm machinery research.


  • Minimising the impact of soil compaction on crop yield. Involved with using controlled traffic technology to reduce the area of compacted soil - DAW00243
  • Sub-soil constraints - understanding and management. Deep ripping with amerolients with precision agriculture techniques can improve crop yield - DAW00242
  • Soil constraints initiative – management of sodic and magnesic soils. Water harvesting seeding machinery, such as the Wesley Wheels, may improve crop yields in a water limited environment - DAQ00200
