Direct Seeding Disc Drills

Built for the harshest of seeding conditions, K-Hart disc drills are one of the toughest on the market.

Our disc drills are marketed to Australia, Italy, United States and within Canada – offering a line up of disc openers to match various soil conditions.

K-Hart offers a wide range of seeding widths from 34 feet to 75 feet with various row spacings. Your choice of disc models attached to our robust frame delivers better results while seeding faster, in wetter conditions, with less horsepower and less fuel.

All Gen II frame can accommodate our exclusive K-Hart fertilizer banders on our unique parallel hydraulic subframe.

We’ll custom build a complete K‑Hart drill to suit your specific needs.

 

 

 

We’ll customize your new drill with K-Hart disc openers.

Model 9612

Designed to replace worn-out John Deere disc openers on the 1890 and 1895 John Deere frames. A very cost-efficient way to still utilize their frame but have a superior K-Hart Model 9612 patented undercut technology disc opener. A very simple design with a way less moving parts.

Model 8612

Designed to have our patented undercut technology. Superior seed placement over other competitor disc drills. Works well in heavier residue and also firmer soil conditions.

Model 4612

Designed with parallel link trip system. A traditional double disc but with a superior bearing system and a 1 ¼" offset blade arrangement compared to the traditional ¾" or even zero offset. Works great in loose soils and moderate residue cover. Best opener for real muddy conditions.

Model 3612

Designed to be the simplest double disc while at the same time to be a very robust opener. Still has our superior bearing system but does not have a parallel link trip system.

“We see the benefits of using a stripper header along with disc drills, in both yield potential and soil health. Our K-Hart disc drill is better built, has less maintenance, and does a better seeding job than competitor disc drills.“

Gene Andreas, Cabri, SK

"K-Hart Industries is a receptive company who uses their own products in their own farming operation thus understanding all aspects of the K-Hart products. Very helpful with technical support due to their hands on experience. The new model 8612 disc opener has less hair pinning than other disc drills."

Rick Goodwin, McCord, SK

“We bought a combine stripper header and needed a disc drill. We own a K-Hart disc drill because of the simplicity and low maintenance. Seed placement is outstanding.”

Mitch Aver, Broadview Montana, USA

"I have ran a K-Hart Industries drill for 3 years. The disc drill allows me to run an inexpensive low horse tractor while pulling 56 feet of drill. It allows me to seed 20% faster compared to other independent opener drills. I also have been pleased by the minimal amount of maintenance needed with the K-Hart disc drill. I feel that these advantages allow me to produce more work with less capital and resources. Finally I have been very happy with the exceptional seed placement and seed to soil contact this drill provides in lentil, canola and cereals."

Jodi MacDonald - Rosetown, Saskatchewan

"K-Hart disc drills are easy to maintain along with substantially lower operating cost versus other disc drills on the market. That is one of many reasons I’ve used a K-Hart for the last several years."

Robert Ellis - Elrose, Saskatchewan

Why choose K-Hart Double Disc Openers?

1. Why choose disc openers over knife openers or spoons for direct seeding?

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

2. Why choose K-Hart double disc openers over competitors' double disc openers?

K-Hart double disc openers Competitors' double disc 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.

3. Why choose K-Hart double disc openers over single disc openers?

K-Hart double disc openers Competitors' single disc openers
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
