Abstract
A quick attaching coupler is mounted to a tractor three point hitch, with a first actuator linked to latches on both sides of the hitch. The first actuator may be moved by a seated operator between a first position wherein both latches are unlatched and a second position wherein both latches are latched. A quick PTO coupler is mounted to the quick attaching coupler, and has a sleeve carrying a first end of a tractor PTO shaft. The sleeve pivots independently of the latches between a first PTO disengaged position and a second PTO engaged position. A second actuator linked to the sleeve may be moved by the seated operator between a first position wherein the PTO is disengaged and a second position wherein the PTO is engaged.
