The Jang Double Disc Opening Shoe improves the performance of the JP1 when there is minor debris present in the soil.
The discs cut through the soil as opposed to plowing through the soil like the Standard Shoe.
If you are farming a no-till style and leave the previous crop roots in the soil, then the Double Disc will help the seeder cut through the debris making the seeder easier to use.
The Double Disc can easily be swapped out with the Standard Shoe in seconds giving your JP1 more versatility.
Works with the JP1 and JP3.
