For interior drilling and sowing, instrument named khappa (tiller) is used, which has iron teeth (arms). The sharpness of this impliment gets reduced or becomes blunt again and again. This needs to sharpen the arms repeatedly, incurring additional expenses every time. Apart from this, deep cultivation in hard soil is also not possible with this instrument. As a solution to this problem, an iron pointed rod on the upper part of the tiller is attached in such a manner that this rod remains two inches out from the teeth (arms) of the tiller. As a result, while drilling or sowing the teeth (arms) do not come in direct contact with the land and hence the arms do not get blunt. And by fitting this iron rod in front of the arms deep and straight drilling of land is also possible. It is experienced that by doing this improvement in the drilling implement the teeth (arms) need to be sharpened only once. Also, deep and straight drilling is possible.
