One of the UK’s leading suppliers of replacement wearing parts is bringing Australian-developed technology to UK direct drilling, with a new serrated disc designed to offer longer wear life and improved residue cutting.
Visitors to Agricast’s stand in Hall 20 at LAMMA 2027 will be among the first to see the Tillageworx 495 × 6 mm Serrated Disc for Horsch Avatar direct drills.
Tillageworx is one of Australia’s most successful providers of replacement parts and, as well as representing Agricast down under, has developed its own product range designed to cope with harsh Antipodean soil conditions.
“We’ve worked with Tillageworx over the last couple of years,” says Agricast’s managing director, William Robinson. “Having lived in Western Australia for several years, it struck me last summer how similar the challenges facing UK farmers had become to those down under. The hot weather, lack of rain, and incredibly hard and abrasive soils were giving British growers significant challenges. Combine these conditions with the increasing adoption of minimum tillage and direct drilling, and the Tillageworx disc offers a longer-lasting alternative to the standard Avatar disc, with the added benefit of improved cutting through crop residue.”
Popular in Australia and North America, this serrated disc design is intended to improve residue cutting and reduce hairpinning, helping maintain better seed-to-soil contact and more consistent crop establishment.
Manufactured from high-grade boron steel, the Tillageworx disc measures 495 mm in diameter and 6 mm thick, compared with 480 mm and 5 mm for the OEM disc. The increased diameter provides additional material for wear, while the greater thickness is designed to improve durability. The larger diameter can be accommodated using the Avatar’s existing seed boot adjustment.
Unlike the standard smooth-edged disc, the Tillageworx design features a continuously sharpened, machined chamfer following the serrated outer profile. This cutting edge is designed to slice through straw, stubble, and crop residue cleanly rather than folding it into the seed slot, reducing hairpinning and helping maintain good seed-to-soil contact.
Agricast also offers a similar serrated disc for the John Deere 750A direct drill, with the potential to extend the range to other makes and models in the future.
The Tillageworx 495 × 6 mm Serrated Disc is available to order now for spring 2027 delivery via www.agricast.co.uk, and can be seen at stand 320 in Hall 20 at LAMMA 2027, which takes place at the NEC on 21st and 22nd January.
