This share body is the mounting structure that holds the seeding coulter and the fertilizer delivery tube on a corn seeder. It attaches to the seed drill frame and positions the coulter at the correct depth and angle for seed placement. A worn or bent share body causes the coulter to drift from its intended path, leading to uneven seed depth and poor row spacing. The manufacturer machines this component to match the original assembly’s bolt pattern and mounting geometry, so the coulter alignment is preserved without shimming.
