Arrangement for improving traction of a ground engaging element of a vehicle

A chisel nut for use in improving traction of a ground engaging drive element of a vehicle, the chisel nut comprising:

• a body having a first end structured to engage the ground engaging drive element and a second end disposed opposite the first end;
• a chisel face defined in a side of the body spaced a distance from the first end and extending to an edge at the second end of the body, the chisel face sized and configured to extend outward from the ground engaging drive element beyond lug members of the ground engaging drive element;
• a through hole defined in the body about a longitudinal axis and extending from a first opening at the first end of the body to a second opening defined in or near the second end of the body, the through hole having a threaded portion structured to threadingly engage with a threaded portion of a cooperatively sized fastener positioned in the hole;
• and
• an indexing structure defined by the body at or about the first end of the body, the indexing structure structured to prevent rotation of the body about the longitudinal axis when the chisel nut is coupled to the ground engaging drive element by the fastener,
• wherein:
• the body comprises a flared base portion extending radially outward from the first end of the body, the flared base portion having an engagement surface structured to engage the ground engaging drive element when the chisel nut is coupled to the ground engaging drive element by the fastener,
• the indexing structure comprises a number of features extending into or from the engagement surface, and
• the number of features comprises a plurality of through holes extending through the flared base.

• a fastener having a threaded portion;
• and
• a chisel nut comprising:
• a body having a first end structured to engage the ground engaging drive element and a second end disposed opposite the first end;
• a chisel face defined in a side of the body spaced a distance from the first end and extending to an edge at the second end of the body, the chisel face sized and configured to extend outward from the ground engaging drive element beyond lug members of the ground engaging drive element;
• a hole defined in the body about a longitudinal axis and extending from an opening at the first end of the body toward the second end of the body, the hole having a threaded portion structured to threadingly engage with the threaded portion of the fastener;
• and
• an indexing structure defined by the body at or about the first end of the body, the indexing structure structured to prevent rotation of the body about the longitudinal axis when the chisel nut is coupled to the ground engaging drive element by the fastener;
• wherein:
• the body comprises a flared base portion extending radially outward from the first end of the body, the flared base portion having an engagement surface structured to engage the ground engaging drive element when the chisel nut is coupled to the ground engaging drive element by the fastener, and
• the indexing structure comprises a plurality of through holes extending through the flared base.
