I'm cleaning out the storage unit & came across a w/b sidewalk edger that the motor is locked up on. It has a 3.5 hp B & S motor on it. I also have a brand new Honda 6.5 hp engine sitting in the garage at the in-laws that he said I can have because it won't work for his project & it's in his way. What's 2 big of a motor to have on a belt driven walk edger? I think I may have a little Tim Allen in me on this project. I'm thinking this should easily be able to handle the 3 blades I was running on it before, probably a couple more even if I want to.
