The Mzuri Pro-Til drill with its strip-till sowing system has not changed from its original concept. In a nutshell, staggered auto reset leading tines open up the soil and clear it of surface trash while at the same time placing fertiliser in the row. Cleated tyres follow to carry the weight of the drill, the ensuing seed coulters then sowing into the previously loosened, and the optionally fertilised, soil. Semi-pneumatic wheels control the depth of each individual seed coulter and firm the soil over the seed. A set of hydraulically controlled tine harrows then level off the seedbed, although not all drills will have these.
