ABSTRACT:
A rotary hoe has a tool bar mounted on a tractor and a plurality of individually pivoted arms carrying hoe wheels. Springs bias the arms in a downward direction to force the hoe wheels into the soil. A rotatable torsion tube supports the springs. An adjustable lock apparatus secured to the torsion tube is used to rotate the tube to adjust the biasing force of the springs.
