I had my first breakdown of the year on my Permagreen Ultra. (800 hours)The upper ball and socket joint on the shifter arm popped out. Called Lesco on cell and they are getting me a new one. I broke the lower one last year. However--in each case I made a satisfactory temporary repair by wrapping a few layers of electrical tape around it. Lost time --about 5 minutes. Anybody else have this problem? Is there a way to prevent it or lubricate it?
