I have a Craftsman 2 cycle trimmer model # 316.791810 which seems to have its flexible drive shaft disconnected at the engine. I can pull the trigger and the engine will rev but the head doesn't turn. When turned off, you can hear the shaft end move around at the handle. Does anyone know the most direct way to disconnect the shaft from the engine? I know that sound dumb, but the shrouding makes it look like there is a scenic route and hopefully a direct way to do the job. If its possible to remove 4 screws instead of 12, I'll go for the 4. Also, does anyone know the manufacturer of the trimmer? All help is greatly appreciated. Bill

I have wanted to do this for years. Now that I have a Mig and an arc welder and more hand tools than I probably should have, I want to build a four wheel drive lawn tractor. Yeah, yeah, yeah, I know. Somebody already did that but I don't want to buy one. I want to build my own. I've considered several options from taking an existing mower and converting it by somehow adding a transaxle to the front, cutting the axles and welding in PTO joints or universal joints to make it steerable all the way to starting from scratch and making my own frame. I am anxious to hear from anybody and everybody who has either done this or has knowledge and suggestions they could share. I'm pretty good at fabrication, metal work, welding and mechanics and what I can't do I have resources I can call on. Anyway, I'd really like to hear some ideas. It has to be able to mow grass and live front and rear hydraulics and PTO would be very cool.
