I am in the process of restoring my 64 110 and have been working on electrical wiring issues. I noticed that my tractor had the neutral safety switch (which was bypassed) my tractor didn't have the main engine shield so I didn't have the PTO safety switch. The throw out assembly does not have the angled piece that engages the switch but it does have the mule drive. My question is how do I know if my tractor had a mower deck added or not. I want to put the PTO switch back on and get a deck for it. I notice Cole Hersee still makes the original switches.
