Stanhay precision vacuum planters accurately plant all vegetable and salad crop seeds to produce top quality, high value crops.

Seed costs remain one of the highest inputs to row crop farming. Coated seed can be easily planted with moderately priced belt planters, but less expensive raw seed requires more sophisticated machinery. Stanhay vacuum planters have the unique ability to plant both coated and uncoated seed. Growers know the ability to plant raw seed (especially odd-shaped seed), and the accurate placement of individual seeds are benefits that well justify their investment in the Stanhay vacuum planter.

Stanhay Singulaire Metering Unit

Stanhay vacuum planters with the Singulaire metering system plant all vegetable and salad crop seeds. Plants raw (uncoated) or coated seed in 1, 2, 3, or 4 lines with unmatched precision.

How it works:

  • A thin, flexible seed plate creates an airtight seal.
  • The tractor powered fan creates a vacuum behind the plate, suctioning seed from the hopper onto holes in the rotating plate.
  • An adjustable singulator removes excess seed, leaving just one seed per hole.
  • Seed is released at the bottom of the unit directly into the coulter.

By choosing the right seed plate, you can plant raw or coated seed at almost any spacing pattern. One seed plate usually handles all the grades of any seed type, saving time and expense.
