Why choose K-Hart Double Disc Openers?

Disc openers (PROS)	Knife openers/spoons (CONS)
Low horsepower requirement	Higher horsepower requirement
Lower fuel costs	Higher fuel costs
Higher seeding speeds while still maintaining a smooth soil seedbed	Higher seeding speeds leave the seedbed very rough relating to higher repair bills for following field operations by traveling over rough ground.
Cannot pull up rocks	Great at pulling up rocks
Seed through high standing stubble. Can use combine stripper headers or straight cutter headers and cut as high as you like. No restrictions.	Monitor how high you cut with your combine header. As a rule of thumb, you should not cut any higher than the width or spacing of your seeding tool.
Seed with the least amount of soil disturbance reducing the potential of germination of weed seeds	Promotes more weed germination than a disc opener
Seed into vine crop stubble with no hang-ups Example: pea stubble	Vines hang on to openers causing bunching in the field.
Seed into wetter soil conditions	Need drier soil conditions to prevent plugging of openers

5206 series double roll ball bearings with triple lip seals on both inside and outside Improved design, better than using tapered roller bearings.	Smaller, inferior single ball bearing with single lip or double lip seal. They use small 204 or 205 series bearings.
The largest and best-protected bearing system in the industry. Besides the triple lip seal protecting both sides of the bearing, you now have the option of greasing this bearing twice a year if you so choose.	Inferior single ball bearing with single lip or double lip seal. They use small 204 or 205 series bearings. Usually non greaseable.
1 ¼" offset leading blade which allows the opener to cut through residue and soil better than nose to nose blades. Easier penetrating.	Nose to nose blades, greatly increased the chance of hair pinning and harder to push in the soil.
16" & 17" Heavy Duty blades made with the latest technology and material available to ensure long-lasting durability.	14" or sometimes 15" lighter material blades.
Largest selection of packers on the market	Limited packer choices
Built Heavy Duty, specifically designed for no-till conditions but can also work in pre-worked ground	Designed more for lighter duty no-till work.

K-Hart disc openers have a less complicated design having fewer moving parts	More moving parts. Depth wheels etc. to plug up with mud.
Can work no-till and pre-worked ground	Single disc openers have problems keeping the disc turning in loose soils
Less horsepower required for blades to roll straight ahead	Single disc openers run on angles requiring more horsepower
Minimum residue disturbance	Most single disc openers use a side depth wheel. This wheel pulverizes the soil it rides on, making the soil prone to wind erosion
