Double Disk Direct Seeding Units / Air Drills
With nearly two decades of experience in building double disk direct seeding disc openers, K-Hart has become one of the leading manufacturers of disk openers.
Our collective ingenuity and experience is available in two different models of direct seeding disk openers, the standard Model 3612 and the deluxe Model 4612.
Why choose K-Hart Double Disk Openers?
Either model can be purchased individually for retrofitting onto an existing cultivator frame, OR as part of a package to complete a K-Hart Air Drill that includes a K-Hart heavy-duty frame in widths available from 34 feet to 80 feet. Click here to find out more about our frame designs.
Disk Bearings: (One of K-Hart's best kept secrets that we are now letting you in on!).
While many competitors' drills use light 204 or 205 series disk bearings which lack axial and thrust support, K-Hart uses a bearing specifically design for tough and dirty seeding conditions. Our 5206 series bearings offers a sealed double row ball, triple lip seal that surpasses any other disk bearing on the market for reliable long term performance.
- Model 4612 and 3612 can be fitted with K-Hart’s optional residue managers. No other residue manager on the market offers all of the following features: adjustable blade angles, an exclusive adjustable spring for different down pressures and a lock up tab when the residue manager is not required. It also has a proven bearing system that will out perform most bearing systems, giving years of trouble free operation. Our steel residue manager blades are made with special wear resistant material for exceptional durability. The exclusive K-Hart trip assembly helps eliminate damage when tripping over rocks allowing up to 10” of trip of travel.
- Both models can be equipped with optional mud scrapers for cleaning between the discs.
- Both models can be equipped with our many different packer profiles.
- Both models can be equipped with K-Hart fertilizer banders.
