Operating Instructions
The SIMBA DTX is an amalgamation of
time proven, successful Simba designed
components brought together to form this
important development. The DTX provides
a one pass mix with a fissured layer at disc
depth for through drainage and root access
to lower horizons. This enables rapid
drainage and access after rain, creating
a greater effective capacity for moisture
compared to ploughing for the same
effective total depth of cultivation.
In principle, the machine is a subsoiler
followed by an offset disc designed for
low draft, high speed operations. The
addition of a rear mounted roll enables
effective cultivation in one pass. The key
to the DTX’s success are the tines which
maintain shatter across the full width of
cultivation. This is followed by the discs
that cultivate the soil surface and minimise
and clod formation. Finally, the rear roll
consolidates the surface, cracks any clods
and firms the soil profile after the rear discs
complete mixing to depth. This starts the
‘top down’ cultivation process, retaining
weathered tilth in the surface level for stale
seedbed purposes. The corrugated top
and shattered lower horizons are left fully
weatherproof to any conditions between
cultivation and drilling whilst retaining
moisture below the surface for rapid straw
breakdown and optimum establishment of
the next crop.
