The Chisel Plough is primary tillage deep plough, working upto
20” to ensure development of crop root system at proper depth and
environment. It is an ideal implement where top soil is fertile
but subsoil is not productive. The Chisel Plough increases
natural fertility of soil as deep tillage provides enough
circulation of air, moisture, and sunlight into soil. For full
penetration in the first pass, a 50 to 85 hp tractor would be
required. A medium (50 hp) tractor will plough 12” in the first
pass and full 20’’depth will be attained in the second pass. With
only one central tine fitted it can work as a subsoiler and upto
maximum depth for breaking of hard pan even with 50 hp tractor.
Yield per acre can be increased considerably by deep ploughing
for wheat, cotton and sugar cane crops. Best fruit orchards
growth is ensured by deep tillage before tree plantation. In
rain-fed areas, the Chisel Plough is an ideal implement because
without disturbing top soil it shatters the subsoil portion of
land, maintaining moisture contents for longer periods and
safe-guarding against water and wind erosion of top soils.
