Still the benchmark for combines

By Country News

With harvesting wrapped up in many farming regions across the nation, it’s the ideal opportunity to mark the 40th anniversary of the Axial-Flow combine and the single-rotor technology that revolutionised the industry.

Introduced in 1977, these combines were a departure from the traditional straw walker design, in that threshing and separation was now performed by a rotor.

The rotary design from United States manufacturer International Harvester was the first of its kind to be mass-produced and represented a giant step forward for farmers, with an increase in capacity translating to a significant boost in productivity.

Case IH product manager Tim Slater said in today’s market, Case IH offered a broad model range to suit any operation, with the efficiency and reliability of the Axial-Flow among the qualities valued most 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.

‘‘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,’’ he said.

In terms of improvements in harvesting efficiency over the years, Mr Slater pointed to increases in horsepower from 170hp in the original 1460 combine to a maximum of 625hp in today’s 9240, along with a number of industry-leading features along the way.

The evolution of the Axial-Flow combine has also been marked by the inclusion of a feeder reverser in 1986 to a rotor reverser in 2003.

Cleaning systems have also evolved with a self-levelling cleaning system with hydraulic cleaning fan drive on the 240 Series, and a cross-flow cleaning system on the 140 Series, in order to maintain performance when the combines are harvesting on slopes.

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

Other milestones include automatic header height control and terrain tracker (automatic header tilt) when used with Case IH fronts, long unloading augers with a pivoting spout, and suspended tracks suitable for controlled traffic farming operations.

‘‘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,’’ Mr Slater said.

The icing on the cake in its 40th anniversary year was the awarding of the Highest Retained Value Award to the Axial-Flow 140 Series combine by EquipmentWatch, recognising its performance and proven value on the market.

It identified the machine as ‘‘an excellent choice for demanding farming needs’’, citing features including the lauded Case IH residue management system built to handle the tough residue associated with new crop genetics, an engine that produces up to 442hp and a grain tank capacity of 10570litres.
