Description
When you’re running fertilizer with your planter, getting that liquid right where it needs to be makes all the difference between a good crop and a great one. This 16-inch smooth edge fertilizer coulter cuts a clean furrow ahead of your seed placement, creating the perfect environment for precise fertilizer application right in the root zone where it does the most good.
What You’re Getting
- 16-inch diameter with 5mm thickness for clean soil cutting and long service life
- Smooth edge design that slices through tough ground and crop residue without plugging
- Five mounting holes on a 4.094-inch bolt circle with 3.189-inch center hole for secure attachment
- Heat-treated steel construction that holds its edge season after season
Built for Real Farm Work
This coulter fits early John Deere 1770NT no-till planters and 1790 series planters – the machines that put millions of acres of corn and soybeans in the ground every spring. Whether you’re planting into heavy corn stalks, working conservation tillage fields, or pushing through tough sod, this coulter opens up the soil ahead of your fertilizer tubes so you get consistent placement even in challenging conditions.
Made to Last
Fertilizer coulters take a beating cutting through everything from rocks to root balls, all while dealing with the corrosive effects of liquid fertilizer. This blade is built from quality steel that’s engineered to handle both the cutting stress and the chemical exposure. The smooth edge design prevents buildup that can affect cutting performance.
Good to Know
This is a direct bolt-on replacement using your existing 8mm mounting hardware. When installing, check that your coulter hub isn’t worn – a wobbly blade won’t cut straight no matter how sharp it is. Keep an eye on blade wear during the season, as a dull coulter requires more down pressure and doesn’t create the clean furrow your fertilizer system needs for accurate placement.
