Description
When your disc blades start looking more like worn-down saucers than cutting tools, your harrow isn’t doing the job it should. A good sharp blade slices cleanly through crop residue and soil, creating that smooth seedbed preparation you need. This 28-inch smooth disc blade from Ingersoll brings back that consistent cutting action and proper soil flow that makes the difference between a good tillage job and just stirring up dirt.
What You’re Getting
- Premium Boron 15B26 steel construction that holds its edge through acres of tough conditions
- Heat-treated to 46-52 Rockwell hardness – hard enough to stay sharp but tough enough not to crack on rocks
- Combo hole design gives you flexibility for different axle configurations on your harrow
- Wear Tuff coating helps resist abrasion from sand and debris in the soil
- 4.25-inch concavity throws soil properly for good mixing and residue burial
Built for Real Farm Work
This blade fits disc harrows using 1-1/2 inch square by 1-5/8 inch round axles – a common setup on mid-size harrows used for corn ground, soybean stubble, and general seedbed prep. Whether you’re breaking up fall plowing or working down spring ground before planting, the 28-inch size gives you good soil penetration without being so aggressive it leaves ridges.
Made to Last
Ingersoll knows farm equipment takes a beating, and they build their blades accordingly. The Boron steel formula is specifically designed for disc blade applications – it stays sharp longer than regular steel but won’t shatter when you hit that inevitable rock or piece of old iron hiding in the field. The Wear Tuff coating adds extra protection against the kind of abrasive wear that comes from working sandy or gritty soils.
Installation Notes
This is a direct replacement that mounts right to your existing gang assembly. The combo hole design means it’ll work with either square or round mounting configurations. When you’re replacing blades, always do full gangs at once – mixing worn and new blades creates uneven cutting that leaves strips. Check your blade spacing while you’ve got things apart; worn bearings can let blades wobble and wear prematurely.
