K-Hart No-Till Double Disc Openers

K-Hart Double Disc Openers are designed to deliver accurate seed placement with minimal soil and residue disturbance.  The openers have good stubble handling ability, especially when teamed with a K-Hart coulter.

Model 3612 – low profile

Designed to be the simplest double disc opener, while at the same time very robust. Has superior bearing system but does not offer the parallel link trip system. 

Model 3612 is a simple double disc no-till opener which rotates on a 1 inch chrome shaft, located in the mount cap for tripping when obstacles are encountered. 3612s offer up to 12” of obstacle clearance.

The 3612s are available in 16″ or 17″ and 

The 3612s will fit frame size of 4×4″ or 4×6″ tubing. 

Double disc openers come standard with urethane bushes and greaseable sealed bearings for reliable long-term performance. 

K-Hart 3612s can be retrofitted to most bars, combines or chisel ploughs.

Model 4612
Model 4612 features a parallel trip linkage giving way for straight up and down travel of 8 inches.

It can be adjusted to different down pressure settings without tools. The 4612 disc offers 16‑inch diameter discs and the disc openers that travel in the tractor wheel marks, have 17‑inch discs. The discs are larger than most competitors, allowing longer field life before they will need replacing. 

Right hand and left-hand blade arrangements ensure that the drill tracks squarely down the field.

Greasing twice a year should allow this bearing to last forever. For the customers that choose not to grease, this bearing will still give several years of maintenance-free service.
