Description
When your disc harrow starts making that grinding noise or wobbling across the field, it’s time to check the bearings. This 1-3/4 inch round bore disc bearing fits Bush Hog, Ford, Krause, and Massey Ferguson disc harrows, getting you back to smooth operation and even tillage. A good bearing keeps your discs running true so they can do what they’re supposed to—cut through residue and prep your seedbed instead of bouncing around.
What You’re Getting
- Greasable design lets you maintain proper lubrication for longer bearing life
- Spherical outer race accommodates misalignment that happens in real field conditions
- 85mm outer diameter fits standard disc gang applications
- Direct replacement for worn original bearings—no modifications needed
Built for Real Farm Work
This bearing is engineered for the tough conditions disc harrows face every day. Whether you’re working through corn stalks, incorporating cover crops, or preparing ground for planting, disc gangs take tremendous abuse from rocks, roots, and heavy residue. The greasable design means you can keep fresh lubricant flowing to the bearing surfaces, which is critical when you’re stirring up dust and debris all day long.
Made to Last
AgSmart builds these bearings to handle the side loads and impacts that destroy cheaper alternatives. The spherical outer race design lets the bearing adjust to shaft deflection and housing misalignment—problems that develop as disc gangs wear and flex under field loads. Quality materials and construction mean this bearing will hold up season after season.
Good to Know
When replacing disc bearings, it’s smart to check the entire gang while you’ve got it apart. Bearings typically wear at similar rates, and replacing just one often means you’ll be back under there next season. Keep the grease fittings clean and hit them regularly with quality disc bearing grease—not general purpose stuff that won’t hold up to the constant pounding.
