Tiny 390 | Mix Soils For Non Wetting And Development

390mm (15”) spacings gives more weight per disc and great clearance for trash and soil flow when comparing with the Tiny 290 although almost all other features remain the same.

The advantage of the wider spacings and the greater weight per disc is more depth can be achieved when conditions are tight and hard to penetrate and at the same time greater soil and trash flow. This spacing was originally developed for applications where breaking through hard pans and mixing and incorporating lime, clay and non-wetting sand was the key objective.

This machine has since found its place in working in new country and suckers. Due to the wider spacings when working in cloddy , tight grazing country the finish is a little rougher than the Tiny 290, however some operators want this type to finish to keep clod size larger to ensure more rain holds and penetrates into the subsoil. 3.5mtr transport width in sizes from 24 plate through to 44 plate in working widths from 4.81m through to 8.5m
