The optimum setting may vary depending on soil cover. In heavy stubble and unworked ground it is
possible to set the swivels low to the ground. In light stubble or loose soil it is best to raise the leading
discs so that the chains ‘feather in’ to the soil.
It is important to note that lowering the swivels will not cause the discs to dig deeper or more
aggressively. It will result in premature wear of swivel hardware and the first two chain links.
It will also cause ridges and furrows.
Digging effectiveness is a result of soil conditions and disc chain construction. The weight, shape, angle
and spacing of the discs are the factors which influence efficacy. On hard dry soils it is unrealistic to
expect the discs to dig fully or evenly. However, they will still perform well for residue breakdown and
seed stimulation.
To prevent injury never lubricate or service the Kelly Tillage System while
it is moving (folding up or down or in working motion)
