Kiwi farm ma­chin­ery man­u­fac­turer Dun­can Ag is to be­come the Aus­tralasian dis­trib­u­tor for Ir­ish com­pany Al­strong. Dun­can will in­tro­duce the Al­strong Auc­tus over­seeder and the Al­strong Aer­a­tor, giv­ing farm­ers and con­trac­tors more op­tions to re­ju­ve­nate pas­ture and aer­ate their soils.

Al­strong was set up by farmer and agri­cul­tural en­gi­neer Alan Win­ters, who de­signs and builds the ma­chines him­self and tests them on his own farm.

Dun­can Ag chief ex­ec­u­tive Craig McIsaac says he saw the po­ten­tial in the Al­strong over­seeder and aer­a­tor when at the FTMTA Field Days at Punchestown in County Kil­dare, Ire­land.

“The 3m-wide Al­strong Auc­tus pas­ture re­ju­ve­na­tor has a unique de­sign that al­lows it to carry out sev­eral op­er­a­tions in one pass,” McIsaac says. “It can be used in sprayed-out pas­ture or cul­ti­vated ground.”

The Auc­tus 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 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.

The Auc­tus can also be specced up 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.

The ma­chine comes standard with the French-made De­limbe air seeder.

Dun­can Ag says the Al­strong Aer­a­tor’s unique de­sign is based on a large drum with 15cm blades which can break up soil pans and shat­ter the soil struc­tures to a depth of 30cm.

Its 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 3m wide and the three-point link­age model is 3m wide.

McIsaac says Al­strong Aer­a­tors can also be used to pre­pare a seedbed in ploughed ground or they can be fit­ted with a broad­cast seeder.

“There are a num­ber of ben­e­fits to aer­at­ing pas­ture,” he says. “By re­duc­ing com­paction from stock and equip­ment it in­creases tol­er­ance to drought, re­leases ni­tro­gen in the soil, and im­proves sur­face drainage.”
