The Case IH Ax­ial-Flow com­bine is still go­ing strong af­ter 40 years

Farms & Farm Machinery - - News -

Case IH is cel­e­brat­ing the 40th an­niver­sary of its Ax­ial-Flow com­bine, which was seen as revo­lu­tion­ary in 1977 as it was a de­par­ture from the tra­di­tional straw walker de­sign to the now ro­tary de­sign

The ro­tary de­sign from the then In­ter­na­tional Har­vester was the first of its kind to be mass-pro­duced and proved to be a chang­ing point for har­vest­ing and pro­duc­tiv­ity.

Case IH prod­uct man­ager Tim Slater be­lieves the re­li­a­bil­ity of the Ax­ial-Flow is why it’s so val­ued by cus­tomers.

“The Ax­ial-Flow turned 40 last year and the tech­nol­ogy has def­i­nitely evolved in that time, but the core de­sign prin­ci­ples are still im­por­tant to­day,” Slater says. “The Ax­ial-Flow has less drive com­po­nents than any­thing else on the mar­ket, this ‘sim­plic­ity in de­sign’ en­hanc­ing the ma­chine’s re­li­a­bil­ity in all con­di­tions.”

There have been a lot of changes for the Ax­ial-Flow over the years, no­tably the changes in horse­power. The orig­i­nal 1460 com­bine had 170hp un­der the bon­net com­pared to to­day’s 9240 com­bine, which has 625hp.

Other no­table changes in­clude the feeder re­verser in 1986 and a ro­tor re­verser in 2003. Clean­ing sys­tems have also evolved over the years, like the self-lev­el­ling clean­ing sys­tem with hy­draulic clean­ing fan drive on the 240 Se­ries, and a cross­flow clean­ing sys­tem on the 140 Se­ries, in or­der to main­tain per­for­mance when the com­bines are har­vest­ing on slopes.

The com­pany says clean-out doors have also im­proved farm­ers’ abil­ity to clean down their ma­chines be­tween crop types or at the end of the sea­son.

“We also started with pre­ci­sion farm­ing, with the first yield mon­i­tors be­ing fit­ted in 1996, which has pro­gressed through to yield map­ping, auto steer­ing, and now the grain anal­yser for mea­sur­ing oil or pro­tein con­tent,” Slater says.

Case IH Aus­tralia also cel­e­brated the 40th an­niver­sary of the Ax­ial-Flow com­bine at last year’s AgQuip expo in Ger­many, dis­play­ing a new model Ax­ial-Flow painted in the orig­i­nal style and colours of its pre­de­ces­sors.
