I have heard of your work before. I'm currently working on harvesting efficiencies myself, just on a bigger scale. My company is currently in the early stages of building a two row harvester. I would like to know more about your experances with cane harvesters. Anyway get in contact with me if you would like to find out more. Ryan Hi

Nice and easy to put on and not much to break or get dirty. What ever happened to the other Cox idea with the weight plate? Is it still being considered or did it die out for some reason? Thanks, Randy That’s a good idea. Nice and easy to put on and not much to break or get dirty. What ever happened to the other Cox idea with the weight plate? Is it still being considered or did it die out for some reason?
Thanks,

As a consultant, It's one of my sources of income at the moment. The program took ~ 3 months to write, and the principles and algorithms it uses longer. 2. I'm also doing a PhD and it will form part of the IP for that PhD. Cheers and all the best, Matt Hi Esmail,

Actually, you've referenced my yield monitor in your paper. It's the AgGuide Yield Monitor. I was employed as an independent consultant to conduct trials on various YM arrangements. As such I'm a bit restricted in my ability to fully discuss the mode of operation as some of it is commercial in confidence. I have been working with cane harvesters for the last ten years, with my specialty being large real world field trials of new innovations. I also developed a full hydraulic model of the interactions between the feed train and chopper in modern billet harvesters, and I can confirm that the graph on www.jaisaben.com is a graph of actual field results. We conducted fully replicated trials using a randomised complete block design differing things like billet length, pour rate, extractor speed, secondary extractor speed etc to ascertain the most repeatable measure under all conditions (the variation in that graph incorporates those various treatments). Each point represents a 4 tonne bin. Basically that YM uses hydraulic pressure transducers throughout the machine and measures temporal flux in those pressures and between sensors. From this we've been able to produce a very highly repeatable and robust YM. The problem with the optical approach (we tried something similar) js that the bulk density of cane differs enormously between cultivars. The problem with other approaches (roller opening) is that as you double the billet diameter, you quadruple its volume, and, again, bulk density differs dramatically between cultivars and crop conditions.
