The Simplest Seeder Ever Made!
The Ndume Air seeder has none of the complex parts normally associated with conventional seed drills e.g. no gears, no clutches, no discs or springs. The conventional 24-row seeder has 24 separate metering units for sowing seed and 24 units for sowing fertilizer. The Ndume air seeder has one metering unit for seed and one for fertilizer. Both metering units are the fluted roller type made of steel and run on sealed ball bearings. Seed and fertilizer distribution is carried out by air through one distributor head and there are NO MOVING PARTS TO GO WRONG. Air for the system is provided by a fan driven by the tractor PTO shaft.
Seeds and fertilizer is put into the ground behind Heavy Duty spring loaded Suffolk Coulter knife openers. Each knife opener unit is spring loaded and will therefore contour-follow in the soil. Depth control is done by the spiral covering roller at the rear of the machine – simply move the roller up to increase depth, or down to decrease depth.
The Suffolk Coulter knife openers are replaceable – simply undo one bolt and slide it out of the tube.
The cultivator is mounted on a three-point linkage system behind the seedbox. Lifting and lowering of the cultivator is carried out by one double-acting hydraulic ram. Power for the ram is supplied by the external hydraulics on your tractor. When lifting the cultivator out of the ground, the drive wheel for the metering units automatically lifts off the tyre and seeding stops. When lowering the machine into the ground the wheel re-engages – ready for seeding.
The Ndume Air Seeder can be used in planting a variety of small seed crops, wheat, barley, oats, sorghum, rice and others.
