Larger diameter pressed steel rings on this He-Va front press from Opico are designed to support the implement’s weight more effectively on soft, light land than the standard 600mm version, with less rolling resistance making it easier to pull on heavy clodding soils as well.

A castellated rib at the centre of each disc provides traction to keep the rings rolling in wet, sticky conditions, as well as on very light soils, says Opico’s James Woolway.
