Improved Scarifier Leads to Top Yields How do you make an already excellent implement even better? That's the challenge faced by Gyral's designers and engineers who constantly review the performance of their Australian designed and built machinery such as the Ag-Boss Scarifier and the Penetrator Scari-chisel. One of their most recent innovations has proven to be highly successful for Peter Johnstone of 'Illinois', Woodstock, a 728ha grain growing property near Cowra, NSW. In July 2003, Peter took delivery of a new Ag-Boss Scarifier - Direct Drill which incorporated as an option, an improved coulter unit for direct drilling into standing stubble. Peter's machine was one of the very first to include this latest Gyral innovation. The major improvement to previous coulter units is the mounting of independently sprung coulter units straight off the front frame clamp, completely separate from the knife/tyne assembly. This gives better trash handling and improved seed placement. Last season, Peter used his 10 metre Ag-Boss, behind a 315hp John Deere 9200 to plant wheat, barley, canola and oats in his heavy red basalt/loam soil. He says that using the deep-fluted coulters to cut through straw/stubble, a good tilth was produced with little or no 'clodding' even in wet conditions. Planting using a Gyral SC Air Seeder in conjunction with the Ag-Boss was a one pass operation, with anhydrous ammonia placed at 100-125mm (4-5") and seed planted at 25-40mm (1-1.5") on 250mm (10") rows.
The impressive ground following ability of the Ag-Boss together with the independent springing and mounting of the coulters and the direct drill shanks maintained an accurate planting depth in all conditions. The results speak for themselves - a 2.5 tonnes/ha Canola crop, a 6 tonne/ha dryland wheat crop and wheat under a centre pivot irrigator is expected to top 8 tonnes/ha. The versatility of the Ag-Boss is such that Peter is currently setting up to sow a millet crop straight into the standing stubble of the irrigated wheat crop! Peter Johnstone is yet another successful grower who has found that Gyral equipment is easy to set-up, maintains accurate planting depth and is designed to perform in todays' farming systems. Gyral is the Australian company that introduced broadacre airseeders to world agriculture in 1956. Since that time the company has continued to be in the forefront of tillage and seeding equipment development and manufacture. Most new developments have come about by Gyral engineers talking to, and above all listening to growers like Peter Johnstone and incorporating their requirements into practical implements that really work. And so today, and for a long time to come, controlled traffic, direct drilling, minimum/zero tillage and conventional cultivation can all be handled by one versatile implement - the Gyral Ag-Boss.
Direct Drill Planter Update The T1200 Series Direct Drill Planter has recently been redesigned to make the planter unit stronger and to give a larger range of movement. The Planter Unit now utilities the strong and successful Penetrator Direct Drill Tyne. This gives great strength and a better range of ground engaging tools. Other improvements include replaceable hardened bushes in the Hydraulic Cylinder mounts to ensure the risk of wear is eliminated in this area. Stay tuned for more information and photos of the new Direct Drill Planter Unit.
