So I've been using an Earthwise reel mower for my backyard last season, but never had the front in good enough shape to use it there. Was hoping to use it this season, but doesn't look like it's doable. The edge of my lawn is too high off the sidewalk so I can't get it to mow along the edge. The dirt is quite a bit above the sidewalk, so not sure how I can even fix it. Any ideas? Maybe the sidewalk has sunk over time?
