Rolling ring

In a loose ring packer-mulcher having

• a. an elongated frame,
• b. draft means on the frame for pulling it in a direction of draft over a field, and
• c. a shaft on the frame normal to the direction of draft;
• d. the improved rolling ring, a plurality of which are loosely mounted on the shaft, comprising:
• e. an inner and outer peripheral face,
• f. two parallel radial faces normal to the peripheral faces,
• g. the diameter of the inner peripheral face is greater than twice the diameter of the shaft,
• h. a plurality of spurs projecting from the outer peripheral face, and
• j. a perforation in the peripheral face for each spur from which the spur was projected,
• k. the spurs are each V-shaped when viewed diametrically,
• m. the V-shaped spurs each present a point on the periphery of the ring,
• n. each of said points is a distance from the outer peripheral face of approximately twice the thickness of the ring.
• p. the width of the base of the "V" is about 2/3rds the width of the peripheral faces and
• q. the width of the base of the "V" is about 4/5ths the length of the spur.
