A push type trimmer [on wheels] is probably only a matter of time. My guess is it will be about 18” cutting diameter. I have also seen requests for a garden roto-tiller which is a logical addition to the EGO family of tools. One request I haven’t seen though is for a push type blower [on wheels]. I think that there is a market for all three of these products. It’s just a matter of when the technology has advanced enough to lower the cost and offer it at a competitive price.
