ABSTRACT:
A garden row marker includes a pair of stakes having ledges to facilitate insertion into the ground. A marking cord is attached to one of the stakes while a take-up reel is secured to the other stake on which the balance of the cord is wound. A reversing roll is provided adjacent the take-up reel. The cord passes from the reel around the reversing roll and back into physical contact with the supply of cord wound on the reel. This is effective for securing the reel after a desired length of cord has been dispensed. This arrangement eliminates the need for any locking or spring biased means to maintain the marking cord taut.
