Tri-Plex Roller 3

Some rock ’n’ roll can help save your harvester

BROADACRE farmers will know that a good way to wreck a header front when harvesting low down pulses such as lentils, peas and beans is to run it through uneven and stony ground. That’s what makes a heavy roller a good asset, with the Flatout land roller from OzValue Ag a cost-effective solution.

“They’re made in China so they’re around half the price of competitors,” Oz Value Ag director Noel Blackmore said.

“They’re commonly used in pulse crops for pushing down small stones and breaking soil clods straight after sowing so headers can run closer to the ground.”

The rollers can be made to specification, with OzValue Ag offering four widths up to 15m. They are an arrangement of one-metre diameter steel tubes on 45mm bearings, with two outer rollers and a centre roller that overlaps to avoid gaps.

The current models are made with 12mm-thick steel, with newer models due out soon to be constructed with 16mm steel to make them heavier and stronger. Mr Blackmore said extra thickness would make a roller less likely to dint when you hit a rock at speed.

While some farmers wait until the pulse crops have emerged before rolling, Mr Blackmore said others will tow the roller behind an air seeder for one-pass efficiency. The 15m LR4050 weighs 8.5 tonnes to apply 557kg of pressure a metre and hydraulically folds to 4m for transport.
