Means for improving the traction of wheeled equipment used in the logging industry comprising an improved skidder ring with clevises to which the connecting tag chains are fastened by a pin preferably secured in place by a spot of welding material. When a tag chain breaks and must be replaced, the pin is severed by a torch permitting the remaining two pin parts to be removed from the clevis. The end link of the replacement or repaired tag chain is secured by a new pin placed in the clevis. A spot of welding material is applied to the pin to hold it in place.
