I do a substantial amount of bed edging every season including re-edging of existing beds and creation of new beds. Until this season my edge has been spade cut, but edging is probably the thing I hate doing most. I typically like to cut my edges anywhere from 4-5" deep (depending on soils, clients desires, etc.) and am wondering if I should go with a Brown Bed Edger or Redefiner? I have found the Bed Edger to cost $2339 at my dealer but haven't researched the Redefiner as much. Thanks in advance for all replies.
