Have trouble with front PTO clutch on a 318 mower. When I engage the electromagnetic front PTO clutch the field starts smoking after about 10 minutes of mowing. Have reset gap on clutch to .018 but the field starts smoking after 8-10 minutes. I replaced the voltage regulator but that didn"t help. This is the second clutch in 4 years. Is the problem electrical or adjustment?
 
I bought a New Clutch, $325.00 About 20 Feet mower on,Electromagnet burned up.Of Course, NO Warranty!!
 
The Deere ones are alum. wire and do not give good service. I wound my own. Made a wooden form & used copper coil wire. Go to Weekend Freedom Machines to get details if interested. It is not easy but mine is working well after ~ 5 years.
 
You've got the right approach, hand wound copper wire. If you use epoxy to pot the coil it should last a long time. It would not be too hard to build a reel and wind a coil using a barbecue rotisserie or something similar to turn it.
