iPaddock Alpha disc seeding units
The benefits of discs with the simplicity of tines. Direct upgrade option for the 1890 model John Deere disc seeder frame and other similar machines.
The unique dual row Alpha disc units offer a low cost, low maintenance precision seeding option for high productivity and narrow row spacings, and will retrofit directly onto most 4″ toolbars including John Deere 1890 model disc seeders, at close to half the price of other disc seeding row units. For not much more than the cost of rebuilding your John Deere disc seeder units, you can now fit an all new set of Alpha discs for years of trouble free operation, while doing a better job of planting your crop, year in, year out.
Each row on the Alpha disc has a custom designed rippled disc governed by a load bearing press wheel to accurately place seeds into a firm, well shaped furrow, without the big issues of mud blockages common on gauge wheel disc seeders. The standard dual row Alpha disc units have 2 discs spaced at 187.5mm (7.5″), which dramatically lowers the cost of having narrow row spacings (for improved yields and weed competition). The unique Alpha disc dual row system also means every disc can be mounted on a single rank, eliminating the serious issue of the rear row backfilling the front row, as happens with conventional 2 row disc seeders.
Seeding with discs can increase productivity by 50% with the same size machine, but conventional disc seeders are notorious for reliability and chemical issues in Australian conditions. Alpha Disc is the solution to these issues.
Compatible with most 4″ (100mm), 6″ (150mm) and 8″ (200mm) toolbars.
Single disc systems typically use an even number of Left and Right hand units to eliminate side draft caused by the 7 degree disc offset, with Left units on the Left and Right units on the right side of the toolbar. This creates a “toe-in” effect which helps machine tracking.
At 187.5mm row spacings you will need 2.67 Standard Dual units per metre width. This equates to 24 units (12L, 12R) for 9m/48 rows; 32 units (16L, 16R) for 12m/64 rows; 48 units (24L, 24R) for 18m/96 rows. Contact us for advice on other configurations.
