How do you change a head on a poulan pro streate shaft trimmer? i can't get the old head off.
Try putting a wrench on the nut that is above the head to hold it steady. Then try turning the head off being aware that the stud the head spins on to has left handed thread on it.
Just below the gearbox there is a slot and when you turn the shaft there is a slot on the shaft that lines up with that one. Stick a screwdriver in the slot when they are lined up and then grab the head and turn it clockwise. (the threads are reversed)
