The present disclosure relates to a Power Take-Off (PTO) coupler (10) and equipment equipped therewith. The PTO coupler comprises a first extremity to be connected to the equipment and a second extremity. The second extremity has a plurality of teeth (14) along a circumference thereof, wherein subsequent teeth are separated from one another by a gap (20), and each of the teeth has a base narrower than its top. When the PTO coupler is engaged to a corresponding receiving coupler, the interlocking of the plurality of teeth and gaps counteract axial load generated during operation of the PTO coupler.
