I want to upgrade the gearcase and chain oiler [is old style] to the new one which has the hedge trimmer attachments. Has any of you done this upgrade. I checked the companies website, Echo, but couldn't find any information concerning this. Doing the upgrade would allow me to use this piece of equipment to trim hedges instead of buying something new. like the Stihl string trimmer with the hedge trimmer attachment. The pole pruner extends to 18 feet. Any suggestions on how to secure it to trailer. My jungle jims won't work for the pole pruner.
