13' Rigid Frame Speed Disc. The Maschio Veloce is a speed disc harrow for shallow seedbed preparation. Discs are arranged on 2 rows with opposing disc direction; wide spacing (24 in.) between rows prevents any soil and crop residue clogging. Every disc has its own independent hub with super-sealed long-life bearings lubricated in oil bath; maintenance time is kept to a minimum. Elements are linked to the frame by a silent block system with 4 rubber dampeners which absorb all vertical stresses and require no recurring greasing as alternative systems do.
