Assuming you do mean the PTO: If you remove the battery, you should be able to see the bottom of the PTO handle with a small hole towards the bottom of it. The end of your cable without the spring will go here. Not sure on this exact mower, but generally on the opposite side, there is a small bracket for the cable to rest in, and then run the rest of the cable underneath to the deck. At the back of the deck will be another bracket that the cable will secure to. From there, look around your pulley system, there will be a hole in the bracket between your pulleys that the spring that's at the end of the cable will hook to. There may be more than one hole on the bracket, but usually the spring can only hook into the correct one. If you have trouble I will get some pictures for you.
