ABSTRACT:
The invention is designed primarily for use with resilient tine components which include a pair of resilient spring coils having an attaching U extending between adjacent ends and a resilient tine extending from the outer end of each of the resilient coils substantially perpendicular to the longitudinal axis thereof. These often wear and the most expensive replacement cost is the resilient spring coils. The present invention overcomes these disadvantages by provided a sleeve which engages over the worn ends of the tines and is secured thereto and which has a replacement tine portion secured within the other end of the tubes and extending axially therefrom thus returning the tines to their original length. The sleeves can be secured to the worn ends of the tines either by welding, set screws or other means.
