RTC - 002 SONAFARM 'MEDIUM DUTY' Rigid Tyne Tiller is designed to withstand tough work and operates as a Light Chisel Plough. The Tiller has heavy-duty shanks for positive penetration. It breaks up hard top soil, uproots stubbles and leaves the ground perfectly worked. It is particularly useful for paddy cultivation areas requiring shallow ploughing on hard clayey cracked up soil. In such places it prepares seed bed faster than ploughing.
