Is it stuck in or stuck out? if its out you dont need to take it completely apart, just take of the star bolts at the end of the stalk near to the shaft. (strimmer, hedge trimmer or whatevet your using inside you will see a hexagonol head, get a large screw driver or pliers and turn it to retieve the cord back to the start, if its stuck in try turning it both ways to unjam it.
