I've got a Jungle Jim Gear Caddy for my trimmers mounted on my trailer. I've had it in use for 4 years now. I believe that there is either a flaw in the equipment or maybe my equipment is manufactured wrong. The hardware of the Gear Caddy has worn a small groove in the shafts of my trimmers. I noticed this damage shortly after it occured. I remedied the situation by placing plastic tubing over the area on my trimmers to insulate it from the metal. Unfortunately, the shaft of my trimmer has broken at the area where the groove was worn into it. This happened three years after the intitial damage. Has anyone else using the Gear Caddy had any similar problems?
