New vertical iHSDs ‘running sweetly’
With harvest getting into full swing in the central and northern Wheatbelt areas, the first commercial units of the new version of the Integrated Harrington Seed Destructor, coined iHSD, are rolling.
About 90 units are expected to operate in WA during harvest, with about 90 per cent of these already rolling.
Growers are reporting largely smooth sailing with the running of the machines, according to McIntosh Distribution iHSD product manager Johnny Inferrera.
He said the systems were running at the optimum kill rate speed of around 3000rpm, which also was maintaining full header capacity.
“The first units to start have now done more than 150 hours, working in crops ranging from 0.5-3.5t/ha and they are rolling along well,’’ Mr Inferrera said.
The latest vertical, mechanical-drive system uses the same mill set as the hydraulic version, with independent testing confirming up to 99 per cent-plus kill rates of targeted weed seeds at various harvester speeds.
Invented by Darkan grain grower Ray Harrington and developed by UniSA with investment from Grains Research Development Corporation, the iHSD has undergone continuing development by DeBruin Engineering, together with national distributor, McIntosh Distribution.
Mr Inferrera said growers were impressed with the iHSDs’ easy operation, as well as unique features like rear hatch access for easily checking grain losses, a stone trap to help prevent foreign objects coming into the system, and a simple bypass for windrowing and-or harvesting without the iHSD.
Cunderdin farmer Norm Jenzen, who has a 4000ha wheat, barley, canola and lupin program to complete, had a new vertical iHSD fitted to the family’s Case IH 8240 harvester and he said it had been “running very sweetly’’.
Mr Jenzen, who said he impressed with the service and support from McIntosh & Son at Merredin, said it was running at 3015-3030rpm and at travel speeds of 8-10km/h in barley.
He said the rear hatch access and stone trap were key attributes the family liked about the iHSD after considering alternative systems. “To check grain losses, we just opened the big door and rock trap, did a few short runs and used a drop tray — and it was beautiful. We got the losses down to 16 kg/ha,” Mr Jenzen said.
“You can open the back door and go windrowing if you want — like if lupins are green and you want to windrow them, or you are doing straw for the hay guys.
“If you have a clean crop and you are doing straw, there are no modifications, you just open the door. You can also get in and still look at your sieves.”
After previously windrow burning, which could also get out of control at times, Mr Jenzen said the iHSD would reduce his stress and effectively save a month of his life.
He said radish was their main problem weed, in addition to ryegrass, and while he did not expect to catch every seed, he knew what would be caught would be destroyed mechanically.
By possibly saving late glyphosate sprays in barley, it also could help avoid grain quality discounts.
Near Carnamah, Scott Bowman has a new vertical iHSD on the family’s John Deere S680 for their wheat, barley, canola and lupin program this harvest.
He said after more than 100 hours, “everything is running well’’.
“The service from McIntosh & Son at Moora was also very good and we have had people out from McIntosh Distribution and DeBruin,’’ Mr Bowman said.
“It’s definitely using a lot of excess power from the S680, but you always have excess with the S680, so it hasn’t slowed down the harvest at all.”
Growers interested in further information about the latest system and early orders for 2020 can contact their local McIntosh & Son dealer.
