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. The conventional 16-row seeder has 16 separate metering units for sowing seed and 16 units for sowing fertilizer. The Ndume air seeder has two metering units for seed and two for fertilizer. The 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 two distributor heads. There are NO MOVING PARTS TO GO WRONG. Air for the system is provided by a fan driven by the tractor PTO shaft.
The Ndume Press Wheel Planter has a large V-shaped presswheel made out of steel. Wheels are mounted at the rear in gangs of 5, 6 or 7 depending on the size of the machine. The advantage of this is that the wheel behind each tine is not isolated, which 1) saves valuable space in the frame, and 2) ensures that the presswheel is less likely to stop going round in wet conditions.
The Presswheels have two functions:
1) They provide good seed to soil contact and therefore good germination, and
2) They depth-control the machine. The 12mm wide heavy duty spring loaded tine penetrates the ground to a depth of 4 to 5”. Because the tine is so narrow very little soil disturbance takes place.
The seeding tube is adjustable both up and down, and forwards and backwards thus allowing exact placement of seed and fertilizer. Seeding tubes are hardfaced on the leading edge to minimize wear.
The Seeding cultivator is mounted on a linkage system behind the seedbox. Lifting and lowering of the cultivator is carried out by two double acting hydraulic rams. Power for the rams 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.
If you do not wish to use Press Wheels, Spiral or Crumble Rollers can be fitted instead.
The Ndume Air Seeder can be used in planting a variety of small seed crops, wheat, barley, oats, sorghum, rice and others.
The Presswheel Planter is suitable for conventional, Minimum Tillage and Zero Tillage farming practices.
