The most accurate and durable seed metering unit.

Less doubles and skips – The flat seed disc of the Monosem seed metering unit is less sensitive to seed size and shape. It picks up multiple seeds and the excess pips get knocked of higher up in the metering unit. Conventional seed meters try to ensure single seed pickup with pockets or grooves on the seed disc. This is only effective when the seeds are uniform in size and shape.

Better seed spacing – The flat seed disc allows seeds to fall straight down from the seed disc at the 5 hour mark. The lower drop position decreases the likelihood of mispositioned seed in the seed furrow. The seed wiper at the bottom of the Monosem seed metering unit ensures that seeds fall down the centre of the seed tube. This accuracy ensures the correct positioning of each pip in the planted row.

Adjustable – The seed singulator is adjustable to fit different seed types (maize, soya, sunflower etc.). You can check for doubles or skips through the control window. You don’t have to make constant adjustments to get the perfect seed spacing. The Monosem system is not sensitive and you don’t have to adjust the vacuum.

Durable – The Monosem seed metering unit is made of aluminium. The agitator, singulator and seed wiper are made of bronze. The components are machined to the micron and calibrated at the factory for life.

Affordable replacement parts – It takes years to have to replace the wear gasket or seed disc. The seed disc is made of 1.5mm stainless steel. The wear gasket of Polyacetal Copolymer has superior friction and wear resistance characteristics.

(1) Cast Aluminium Cover (2) Control Window, Operator can easily see the result of their adjustments (3) Clean Out Trap Door (4) Brass Seed Wiper, directs seed release to guarantee precise seed spacing (5) Adjustable Brass Singulator, eliminates doubles without creating skips (6) 1.5mm Stainless Steel Seed Disc (7) Brass Agitator (8) Seed Drop Point, right above the seed tube (9) Wear Gasket, teflon gasket behind seed disc will last for many years (10) Hold Down Plate (11) Main Body of Meter

Adjusting the Seed Singulation :

The lever on the left hand side of the main body, adjusts the Singulator on the inside.

The more the lever is set towards PLUS the less aggressive the Singulator is, therefore allowing more seeds to pass. The more the lever is set towards MINUS the more aggressive the Singulator is, therefore allowing less seeds to pass.

The most accurate and durable fertiliser auger.

The Fertisystem Auto-Lub® augers are made from highly durable corrosion free components. The stainless steel Fertisystem® auger shaft runs on two 6006.2RS ball bearings that are well protected. The protection consists of a stainless steel washer, felt seal, exit hole, o-ring, oil seal and bearing seal. This design ensures many years of performance without much maintenance. The Fertisystem Auto-Lub® augers are fertiliser augers of a new generation. These augers are maintenance free and require minimal cleaning. Their open, spiral-like screw are very accurate and work well even with damp or powdery fertilisers.

Reliable Flow Rate:

East Maintenance:

The rain cap (1) can be taken off to allow the tractor driver to see the flow of the fertiliser. Should there occur a blockage in the opener, the fertiliser will overflow through the opening (a) even if the rain cap is in place.

Emptying, cleaning and checking of the FertiSystem auger is made easy. Just unclip two latches and the front spout (2) can be taken off. Thereafter the auger screw (4) can be pulled out by hand.

The overflow plate (3) inside the outlet spout ensures uniform fertiliser distribution even if the planter runs uphill, downhill or leans sideways on slopes. The corkscrew design of the FertiSystem auger makes the screw self cleaning and fertiliser is unable to clog around this screw even if the fertiliser is damp or powdery.

No-nonsense design with heavy and robust frame constructions

  • short chains and lowest possible amount of bearings & shafts
  • easy to set, operate and maintain
  • designed to work with large fertiliser openers on a separate front beam
  • strong enough to carry fertiliser bins over the full width of the frame

Fertiliser opener options:

  • 460mm No-Till Coulter & Tine Combo
  • 460mm No-Till Coulter & 380mm Double Disc Combo
  • 510mm Single Disc
