15 Seed Terminator Some of the seven Seed Terminator owners visited were on their third harvest with the chaff mill, having owned the mill since they were first released in Others were running a Seed Terminator for the first time. All were running the 2019 version of the mill with all reporting improved mill wear and longevity. A number had a set of highflow mills back in the shed but none had utilised them. Power draw and capacity was still an issue for one owner who, part-way through harvest, installed a Steinbauer engine chip in a new New Holland 8.90 to take it up to around 9.90 equivalent power specifications. Post chip installation, the owner reported the harvester had returned to an acceptable capacity, in line with what was expected from an 8.90 without a chaff mill fitted. Two owners specifically noted they were happy with the width of milled chaff spread, saying that it made the full 12m working width evenly. Two owners had issues with drive belts slipping. One found the wrong belt size had been supplied initially which was quickly rectified. The Seed Terminator arguably has one of the highest kill rates of the mills on the market and since we last looked at it in detail in 2017, has been refined to reduce power draw while maintaining high levels of weed seed kill. WHAT WE LIKED High kill rates Swapping mills takes only 20 minutes High flow reduced kill mill option Ongoing mill research and development WHAT COULD BE BETTER Bypassing and sieve loss check more complex than others (model dependent) Limited access to sieves (model dependent) Complexity of a gearbox ($8956 replacement cost) No ISOBUS terminal integration option No. 121 February 2020 Research Report 15

40t/h grain). These samples are spread in soil bins at low density to not impact seedling growth. Blind germination counts are made weekly by the Uni. Samples are compared to a control (unprocessed sample) to give a % kill value AND compared to a reference mill sample. The % kill value depends on seed batch properties (eg moisture%, seed size & weight) that vary wildly. % kill is not comparable from different sources. Reference mill is comparable and allows us to improve our tech year on year. To validate the Seed Terminator in a range of operational conditions, weed species, chaff types. Also testing has been performed by Michael Walsh using agar propagation processes that he and others developed at University of Western Australia. We have also had testing performed in Germany by the University of Hohenheim, validating in greener conditions and killing black grass. We have also been working with University of Missouri on local species. 8. What tools and process are required to remove the mill to revert to standard operation? a. Seed Terminator is mounted using 6 bolts. Belt and electrical cable must be removed. Lower machine using forklift. b. Approximately how much time is required to remove the mill? 1-2 hours. c. Or can the mill be bypassed in the field for alternative chaff management? (for example when green canola blocks the mill) Yes d. In these cases, what is required to bypass the mill? John Deere 2 minutes: chopper drive out, drop bypass door down, disconnecting the belt is optional. A 20 minute procedure for all other makes, details below. Case IH remove inlet chutes, put standard chaff tray back in. Massey Ferguson chaff use standard spinner bypass door. New Holland & CLAAS remove screens run in spreader mode. 9. Are sieve loss measurements possible with the mill fitted? Yes a. Please provide details on how this can be done: See above, Bypass mill, keep the airflow similar by not creating large opening for chaff and air to escape but rather spread as per as per OEM design, replicating true grain loss. As the characteristics within the cleaning shoe can be heavily influenced by modifying airflow within the cleaning shoe resulting with increased losses or poor cleaning shoe performance. 10. Are there any machine warranty impacts or have these been addressed directly with harvester OEMs? Yes Details: Attachment warranty applies. Similar to putting any non-oem attachment to a tractor. With CASE IH machines, customers are able to purchase genuine drive kit specifically designed for driving the Seed Terminator. 11. In terms of product support, in what areas is the mill supported by dedicated staff or a dealer network? We are using a dealership model. We do not want to interrupt the harvester market. Buy your Seed Terminator where you buy your harvester. Get it serviced with the harvester. Harvesters that kill weed seeds is a complex interaction, to get the best outcome for the dual purpose machines so we are investing heavily in in field harvester specialists to help dealers and provide support; Joe Limbaugh (WA), Brett Asphar (WA) and Keagan Grant (SA). 12. Can the mill be transferred to a new harvester when machines are traded? Yes a. What is the process and cost? We have learnt so much about the total ownership cost. Fitup cost and swapping cost is very important, as is machine depreciation. The process and cost depends on the machine type. JD we have got fit-up times down to 6 hours for two people. We are pushing this time down on all machines. 13. Will 2020 mill designs be altered as a result of learnings from the 2019 harvest? Yes Please detail changes: We always make improvements to mill technology as we will offer the best technology possible. We are working on our MY20 mill tech at the moment. 14. How many of these systems do you now have operating in the field and where are they located? There are over 150 Seed Terminators operational. We have 3 units in the USA, 2 in Canada and 1 in Germany. 15. What measures are integrated into the design to stop stray material entering the mill? For example, rock traps or magnetic capture systems? Seed Terminators now come standard with our patent pending magnetic capture system to prevent ferrous material entering the mill. The mill is designed to be highly robust. When you have 150 machines out there you would be amazed by the crazy things that end up in the mill, so capturing what we can is important. 16. How will chaff mills be used in the future and how might designs evolve? Our vision is that every harvester on the planet is not spreading weed seeds to become next year s problem. Global adoption is a massive challenge and we have certainly learned a huge amount about the diversity of agricultural crop types and conditions by entering into the United States, Canada and Europe. We have also found that with scale (150 units to date) random conditions begin to occur. We invest everything we have back into research and development to create new solutions for these challenges. We have developed a range of different mill options for different conditions and requirements to kill seeds and we see this only evolving in the future. You set the harvester up for different crop types so why would the mill be any different? The mills are only as good as what you get into them. We see a future where harvesters are redesigned to target weed seeds get more in the front and more into the mill. Also our milling technology has improved every year and we are not done yet. We work on making future proof tech, so you can always upgrade to the latest mill tech. Other notes: When looking at what to do with your weed seeds remember that nothing is for free. You cannot kill weed seeds without using power, in the case of ryegrass, a lot of power. Think of power use and wear like a chemical rate application. It is an investment in control. The last few surviving weed seeds are hard to kill but letting them go free is possibly a low dose experiment. We have developed lower power versions for the scenario when you are tempted to bypass the machine. Something is way better than nothing. But high kill is worth a lot more in the long run. Harvester set up: Good harvester setup has a huge implication on the overall performance of the harvester-seed Terminator system. There are threshing system setup which effectively reduce the drag of the rotor and free engine power to run the mill. First pass threshing is key as it minimizes
both rotor(s) losses (weed seeds and grain) and cleaning shoe losses, as straw exiting the separator body is more intact while being fully threshed and free grain separated from the straw load. Blank separator grates have been used to further reduce shoe loading on some machines. With less material on the sieves, the Seed Terminator has less material to process and hence uses less power. Detailed airflow measurements confirm that the Seed Terminator is not impacting the sieves under varied loads and setups, hence our recommendation is to run with the same fan speeds as without the Seed Terminator. It is important to ensure that the cleaning shoe is balanced across width. There have been times when mill speed has dipped on one side and has identified an unbalanced cleaning shoe. While cleaning shoe loads will also be reduced of MOG (material other than grain) allowing for the grain savings effect of the cleaning shoe to take place. With this approach overall harvester performance/optimization will be reached, which reduces the load on the Seed Terminator making it seem as if its not there.

18 Mill wear on a John Deere S680 after 100ha lupins at 1.8t/ha, 600ha canola at 1.2t/ha, 700ha frost affected barley at 2t/ha (3.5t/ha stubble), 1100ha frost affected wheat at 2t/ha (3t/ha stubble). A folded steel frame that bolts to the SCU for forklifting off is a neat arrangement making mounting and removal safer and more simple. The unit can be quickly disabled by disengaging a dog clutch on the mill gearbox drive pulley. This allows the whole unit to be put out of action relatively quickly if encountering excessive blockages, in for example, green GM canola. The entire unit can be slid up out of the way on the John Deere straw chopper slide rails, allowing easy access to the sieves. The drive system consists of a shaft which runs underneath the mills, driving the two mills in opposite directions. As they are wearing on different faces, the mill stators can be removed, flipped over and installed in the opposite mill, allowing wear on both sides. But at double the replacement price for a stator set, the benefit of flipping the mills is negated. Only one owner we spoke to had put sufficient wear on the mills to warrant flipping the stators to wear out the other side of the stator elements. Some issues with the process of laserapplied tungsten coating were identified in a batch in the 2019 harvest which was quickly addressed by the manufacturer. We have no doubt Redekop will continue to work on refining the SCU and will be competitive in the market with other brands in the next months.

25 e. Please detail the weedkill validation and test procedure for the claimed weedkill % (eg chaff flow rates/lab or field testing/ weed species/soil bin or agar admix/seed moisture levels etc): The development of the Seed Terminator testing procedure has been a major collaboration Trengrove Consulting (SAGIT project TC117) the University of Adelaide Weeds Research group David Brunton, Sam Kleeman, Gurjeet Gill, Chris Preston and Peter Boutsalis and Seed Terminator s own Nick Berry s PhD thesis. TC117 validated kill across a spectrum of weed seeds and showed that annual ryegrass needed to be the focus for future testing; not only because of its prevalence in Australian agriculture but also because it is smaller, lighter and tougher than most seeds to kill. Wild oats, brome grass, radish and volunteers (canola, wheat, barley) are straightforward to kill. Testing procedure involves 2kg wheat chaff samples being laced with 10g ryegrass seed. Chaff is then processed at a rate of 1.5kg/s (

19 TecFarm Weedhog in development A novel design, the Weedhog, has been in development for a number of years and will be introduced to the Western Australian market in small numbers over the next 12 months. Already working in the harvest weed seed control space, TecFarm is known for its chaff-carts, but has invested considerable research and development money into this chaff mill design. In-field testing utilising the mill dosing tube method alongside prototype development has delivered a kill rate of around 80 per cent. The unit would typically sit higher off the ground than pictured, but due to the limited availability of some components prior to harvest, a mounting angle compromise was made for this prototyping model. Nevertheless, the two 585mm diameter stacks of rotor bars on two shafts rotate in the same direction with interaction of the mill and milled material at an open section of the housing. This interaction point sees chaff and weed seed material impacted between counter rotation of the rotors on at this point. At a targeted market price of around $50-60,000, the Weedhog is looking to attract a relatively large market segment of harvester owners with lower capacity or older machines. It could be argued that alternatives like chafflining are offering higher rates of kill with less complexity, but nutrients are spread and kill rates with the Weedhog are likely to improve. These developments will be watched with interest. More details: Weedhog mills. Internal fan blades on the Weedhog. No. 121 February 2020 Research Report 19
