TOO many passes with a Cambridge roller can result in over consolidation if the intention is to break down tilth and create a light and even seed-bed.
In order to reduce compaction, Twose has developed a levelling board to work in front of its 6.3m and 7.2m hydraulic folding Cambridge rollers.
The levelling board features flat spring tines with adjustable points, which are designed to pre-till and level topsoil before the final seed-bed is produced by the roller.
For different soil conditions where there is the need to vary shattering effect, the spring tines can be altered in height and angle, while the drawbar length can be adjusted to allow tight turns. *
