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.

The apparatus of claim 1 further comprising a toothed coupler connected to the first end of the tractor PTO shaft. 4. The apparatus of claim 1 wherein the first actuator is a handle that pivots between about 10 degrees and about 60 degrees. 5. The apparatus of claim 1 wherein the second actuator is a handle that pivots between about 10 degrees and about 60 degrees. 6. An apparatus comprising: a quick attaching coupler mounted to a tractor three point hitch, the quick attaching coupler having a frame, a hook on each side of the frame, each hook having a latch pivotable between a first unlatched position and a second latched position; a first actuator linked to both latches, the first actuator movable between a first position wherein both latches are unlatched and a second position wherein both latches are latched; a quick PTO coupler mounted to the quick attaching coupler, the quick PTO coupler having a sleeve carrying a first end of a tractor PTO shaft, the sleeve pivotable independently of the latches between a first PTO disengaged position and a second PTO engaged position; a second actuator linked to the sleeve, the second actuator movable between a first position wherein the PTO is disengaged and a second position wherein the PTO is engaged; and a bumper extending from the rear of the quick PTO coupler and having a sloped rearward extending surface. 7. An apparatus comprising: a tractor having an engine, a power take off connected to the engine, and a frame having a cross member and left and right downward extending legs, each leg having a rearward facing and upward opening hook, each hook having a latch, both latches linked to opposing ends of a cross bar having a longitudinal axis parallel to the cross member, the cross bar rotatable between about 10 degrees and about 60 degrees with respect to its longitudinal axis, the cross bar connected to a first actuator to rotate the cross bar and move the latches between a first unlatched position and a second latched position; and a sleeve suspended under the cross member by a yoke hinged to the sleeve and to the cross member, the power take off extending through the sleeve, the sleeve moving forward to move the power take off to a first disengaged position and rearward to move the power take off to a second engaged position, the sleeve linked to a second actuator to move the power take off between the first disengaged position and the second engaged position. 8. The apparatus of claim 7 further comprising a pair of hinged yokes suspending the sleeve under the cross member. 9. The apparatus of claim 8 further comprising a toothed circular plate attached to the power take off. 10. The apparatus of claim 8 wherein the second engaged position may vary between about 3 inches and about 24 inches from the first disengaged position. 11. An apparatus comprising: a tractor having an engine, a power take off connected to the engine, and a frame having a cross member and left and right downward extending legs, each leg having a rearward facing and upward opening hook, each hook having a latch, both latches linked to opposing ends of a cross bar having a longitudinal axis, the cross bar rotatable between about 10 degrees and about 60 degrees with respect to its longitudinal axis, the cross bar connected to a first actuator to rotate the cross bar and move the latches between a first unlatched position and a second latched position; a sleeve suspended under the cross member, the power take off extending through the sleeve, the sleeve moving forward to move the power take off to a first disengaged position and rearward to move the power take off to a second engaged position, the sleeve linked to a second actuator to move the power take off between the first disengaged position and the second engaged position; and a bumper extending over and rearward of the sleeve and having a downward and rearward sloping surface. 12. An apparatus comprising: a tractor having an engine, a power take off connected to the engine, and a frame having a cross member and left and right downward extending legs, each leg having a rearward facing and upward opening hook, each hook having a latch, both latches linked to opposing ends of a cross bar having a longitudinal axis, the cross bar rotatable between about 10 degrees and about 60 degrees with respect to its longitudinal axis, the cross bar connected to a first actuator to rotate the cross bar and move the latches between a first unlatched position and a second latched position; a sleeve suspended under the cross member, the power take off extending through the sleeve, the sleeve moving forward to move the power take off to a first disengaged position and rearward to move the power take off to a second engaged position, the sleeve linked to a second actuator to move the power take off between the first disengaged position and the second engaged position; and a vertically oriented bar extending through each leg between the latch and the cross bar. 13. An apparatus comprising: a sleeve having a first end of a power take off shaft extending thereth rough; a toothed coupling attached to the first end of the power take off shaft; a pair of yokes having hinged upper portions and lower portions to swing the sleeve forward and rearward; and a spring urging the sleeve rearward; and an actuator linked to the yokes and movable to swing the sleeve forward out of engagement and rearward into engagement. 14. An apparatus comprising: a sleeve having a first end of a power take off shaft extending thereth rough; a toothed coupling attached to the first end of the power take off shaft; a pair of yokes suspending the sleeve and hinged to swing the sleeve forward and rearward; and a spring urging the sleeve rearward; an actuator linked to the yokes and movable to swing the sleeve forward out of engagement and rearward into engagement; wherein the actuator is a handle, and further comprising a slotted plate through which the handle extends. 15. The apparatus of claim 14 wherein the slotted plate has a slot with a catch position to hold the handle in the forward position. 16. The apparatus of claim 14 wherein the rearward position is between 3 and 24 inches from the forward position. 17. An apparatus comprising: a quick attaching coupler mounted to a tractor three point hitch, the quick attaching coupler having a frame, a hook on each side of the frame, each hook having a latch pivotable between a first unlatched position and a second latched position; a first actuator linked to both latches at least partially through each side of the frame, the first actuator movable between a first position wherein both latches are unlatched and a second position wherein both latches are latched; a quick PTO coupler mounted to the quick attaching coupler, the quick PTO coupler having a sleeve carrying a first end of a tractor PTO shaft; a yoke hinged to the frame and to the sleeve such that the sleeve can swing fore and aft between a first PTO disengaged position and a second PTO engaged position; and a second actuator linked to the sleeve, the second actuator movable between a first position wherein the PTO is disengaged and a second position wherein the PTO is engaged. 18.
