The vacuum system and how it works:

The patented metering box is the heart of the Monosem NG Plus planter- it doesn't skip a beat. Each component of the metering system is precision engineered to ensure accurate seed singulation every time you plant. There is no plastic used in this critical part of the machine, only durable metal parts that won't warp or easily wear.

The Monosem heavy-duty stainless steel seed disc is precision made for accurate seed singulation. Unlike a cup metering system that is used for round seeds, the flat surface of the Monosem stainless steel seed disc allows for even the most irregular seed shape to be suctioned and gently held to the disc.

The vacuum is created by a centralized turbofan. An adjustment on the metering box lets you regulate the amount of vacuum in relation to the weight of the seed being planted, and at the same time sets the height of the seed scraper to the size of the seed. As the seed disc turns, a brass ejector block assures that the seed is dropped at a consistent angle to reduce seed bounce inside the seed tube. The results are precision seed spacing every time!

Seed discs are changed in 4 easy steps!

1. Remove cover by loosening wing nuts

2. Lift out seed scraper and seed disc

3. Insert new seed disc and scraper

4. Replace cover, and tighten with wing nuts

Shown above, the precision of the metering box results in accurate seed singulation. Corn seeds are suctioned to the seed disc, unlike a positive air system that blows seed. Stainless steel seed discs with a smooth surface provide long life and gentle handling of the seed.

The trap door provides easy access to empty the metering box when finished planting.

It's easy to change from crop to crop

The correct seed disc is selected based on the size and weight of the seed. A bean see disc, for example, can plant a variety of bean seeds. When planting different crops, you need only adjust the metering box vacuum and change seed discs.
