Go Knuckey or simular. A full width belt means no more seed dropping between belts and ground to a paste and building up on rollers. No more problems with centre belt slipping due to roller flex. Has a big table auger too.thankyou scott and travis. could be more problem than its worth. now looking at a countrywide pickup, wagga wagga ,Australia and it looks ideal. all 4 rollers are driven with a 28" table auger, ideal for canola. cheers kit.
