Heavy Duty Disc Opener Assembly for Sunflower 9100-9400 Series Drills

Description

When you’re getting ready for planting season and need to replace worn disc openers on your Sunflower drill, this heavy-duty 15-inch assembly gets your drill cutting clean, even seed furrows again. The combination of a sharp, properly beveled disc and quality bearing assembly means you’ll slice through residue and create the perfect seedbed for consistent emergence, even in tough no-till conditions.

What You’re Getting

• 15-inch diameter disc with 3.5mm thickness provides the right balance of durability and soil penetration
• Pre-assembled bearing flange and disc configuration saves installation time in the shop
• Quality USA-made disc blade holds its edge longer than imports
• 5/16-inch rivets provide secure attachment that won’t loosen under field stress
• Bearing flange positioned opposite the bevel for proper soil flow and residue clearance

Built for Real Farm Work

This assembly fits Sunflower 9100, 9200, 9300, and 9400 series drills from 1999 and older models. These drills are workhorses for no-till and minimum-till farming, whether you’re planting soybeans into corn stubble, establishing cover crops, or seeding small grains. The 15-inch disc size gives you the penetration power needed for challenging field conditions while maintaining accurate seed placement.

Made to Last

AgSmart builds this assembly to handle the punishment of cutting through tough residue, rocks, and compacted soil year after year. The bearing assembly keeps the disc spinning freely even when debris tries to bind it up, while the USA-made disc blade maintains its cutting edge through thousands of acres.

Installation Notes

This is a direct replacement for original SN7261 assemblies—no modifications needed. The dust cap (part 527-144266) is sold separately but recommended for keeping bearings clean in dusty conditions. When replacing one opener, check the others on that rank since they typically wear at similar rates.
