Abstract
A deep groove ground-contacting roller for a reel type mower assembly having a plurality of interfitting intermediate roller segments and matching end segments mounted on a transverse bearing mounted axle rod in tight abutment. Stop rings engage the end segments and the axle rod to fix the roller segments on the rod to form a roller body. Each roller segment includes a cylindrical hub and a disc element extending radially therefrom with converging planar annular side surfaces intersecting to form a rounded ground-contacting ridge. The disc elements and the hub sections combine to form a deep groove with angled side surfaces and a right circular cylindrical bottom.
