Wizard Multi-row Ultra-Precision Vacuum Seeder for Vegetables
For those looking for the ULTIMATE in precision seeding: Look no further. The Italian-made Wizard brand seeders are virtually 100% accurate, and will handle ANY seed size when equipped with the appropriate seed plate.
The engineer who started this company used to work for “Mater-Macc®”, which is an Italian company widely recognized for high-accuracy vacuum seeders for large 4-wheel tractors. This fellow decided to offer the same technology to smaller-scale growers by offering more affordable units to fit smaller 4-wheel tractors and walk-behind tractors. Even better: He made improvements to the old “Mater-Macc®” design, allowing for easier changing of seed plates and chain sprocket ratios.
The seed-singulation mechanism employs a rotating stainless-steel disc (easily changeable according to seed size desired) that has vacuum applied to one side to “suck” the seeds into the holes in the plate, guaranteeing that only one seed at a time is picked up. The vacuum is then cut off when the plate rotates enough that the seed is over the “drop” tube, and the seed falls down through the adjustable-depth “shoe” to be planted. Seed spacing is controlled by both hole spacing in the plates, and easily-changeable sprockets on the chain-drive. The potential seed-spacing range is HUGE… three-quarters of an inch at the least, and up to 44 inches at the greatest…and just about anywhere in-between. The seed hoppers can also be removed quickly for dumping out excess seed at the end of a planting.
Wizard actually offers about 40 different seed-plates for different seed types / spacings. BUT, we did the calculations and found that when taking into account drive-sprocket adjustments and seed size-vs.-average spacing, you can plant a wide variety of seeds and achieve a good range of spacings with relatively few plates. (It helps that with a vacuum-seeder, the seed sizes do not have to be matched perfectly to the hole size in the plates for good seed singulation, like they do on most seeders…the vacuum just sucks the seed up against the holes, so as long as the hole is SMALLER than the seed so the seed doesn’t get sucked through [and the hole is big enough to allow sufficient airflow to pick up the weight of the seed], it WORKS.) Seeders are priced without any seed plates; you choose which ones you want based on your applications. (Plates priced below.)
Available in One-row, Two-row, or Three-row configurations. On multi-row setups, row spacing is quickly adjustable on the mounting bar; minimum row spacing is 10 inches…PLUS, there are “splitter” kits available to convert each seeder-unit to 2 or 3 rows for denser plantings (see below). Also, systems are “expandable” (for example, if you purchase a 1-row unit and want to convert it to a 2-row later, you can purchase the needed parts to do this) or “shrinkable” (for example, if you purchased a 3-row setup but want to remove 2 of the seeder-units to just plant one row, you can quickly take them off the frame). The operator can either walk in-between rows (as shown in these pictures) or offset tractor handlebars to one side and walk next to the seeders.
These seeders are expensive, but the time and money they can save you in seed savings AND not having to “thin” crops make them worth considering for established vegetable farms.
