I am having trouble with this mower. All of a sudden the reel won't turn. It makes a crazy racket when I try to operate it. I can turn the reel by hand in both directions. Also, I have removed the electric reel mower and verified that the shaft turns when activated. After digging deeper I pulled out the shaft coupler and decided that it doesn't feel like it is grabbing the splines as securely as it should be hence the terrible sound. However the engagement travel seems to be limited. The only apparent solution seems to be slide the reel and shaft towards the outboard electric motor. Does anyone know how to do that on a Jacobsen full floating head? I'll take a picture when I get home. On a side note...how to reels disengage so they don't tear up if they get jammed?
