Structure is associated with the twine feeding needle mechanism of a baler and hydraulically operated tension means in an arrangement such that at the time the needle in an upper position thereof feeds the twine to a knotter, the tension means is released so that excess twine can be obtained from between adjacent bales for tying the knot. The release is accomplished by a linkage secured to the needle mechanism or by a valve disposed in the path of and engageable by the needle mechanism.
