Duncan Ag has introduced two new well-engineered machines from Ireland to give farmers and contractors more options to rejuvenate pasture and aerate their soils.
The machines are the Alstrong Auctus overseeder and Alstrong Aerator.
Duncan Ag chief executive Craig McIsaac first saw the Alstrong products at the Farm Tractor and Machinery Trade Association Field Days at Punchestown in County Kildare, Ireland. He could see they offered something different to what other manufacturers offered in Australia and New Zealand so Duncan Ag became the Australasian distributor for Alstrong.
Mr McIsaac said the Alstrong company was set up by farmer and agricultural engineer Alan Winters, who designs and builds the machines himself and tests them on his own farm.
‘‘The 3m-wide Alstrong Auctus pasture rejuvenator has a unique design that allows it to carry out several operations in one pass,’’ Mr McIsaac said.
‘‘It can be used in sprayed out pasture or cultivated ground.’’
It has 10 individually sprung levelling boards that scarify and scratch the surface to remove dead grass, expose the soil and create a shallow seed bed.
The levelling boards are followed by a heavy duty roller drum with teeth that break up surface pugging and allow air and water to enter the surface layer of the soil. An air seeder broadcasts the seed behind the roller using splash plates.
Behind the seeding zone the Auctus can be specified with grass harrow finger tines or heavy-duty prismatic rings that set the seed in the soil.
A shield over the roller stops soil from the rollers getting into the seeding area.
Mr McIsaac said the Alstrong Auctus was a very well-built machine.
‘‘It has a strong structural steel frame and weighs 4.5tonne. You can increase its weight to 5.2tonne with water ballast.
‘‘It is a trailed machine that follows uneven contours and the 15mm blades on the roller drum are made of hardened steel.’’
The Auctus comes standard with a French-made Delimbe air seeder or Duncan Ag can fit it with an APV seeding unit.
Alstrong Aerators are also heavy-duty machines.
They have a unique design based on a large drum with 15cm blades that can break up soil pans and shatter the soil structure to a depth of 30cm when used in dry conditions at the correct speed.
In pasture it does its job without disrupting the grazing system.
The blades are set almost perpendicular to the direction of travel but at a slight angle, which adds a twisting motion that helps break soil pans.
The weight of the roller is concentrated on each blade as it enters the soil, and the fast working speeds (up to 20km/h) also help shock and fracture the soil.
The aerators come in three different versions: trailed models are 2.5m wide or 3.0m wide, and the three-point linkage model is 3.0m wide.
Mr McIsaac said Alstrong Aerators were versatile machine that could also be used to prepare a seed bed in ploughed ground or they could be fitted with a broadcast seeder.
‘‘There are a number of benefits to aerating pasture,’’ Mr McIsaac said.
‘‘By reducing compaction from stock and equipment it increases tolerance to drought, releases nitrogen in the soil, and improves surface drainage.
‘‘Alstrong Aerators complement the other equipment Duncan Ag supplies, and will enable us to better meet the needs of our customers.’’
