    10" is quite far in my opinion. I think 4" is fine, if installed on swing arms, or swing pipe with marlex ells to allow a little give when they get driven over.

    marlex ell swing joints render the heads immune from rider mower runover damage

    I wouldn't say completely immune, but much less likely for damage. I've replaced swing joints and marlex ells that were damaged. But it is very rare. It's also very rare to see marlex at all. Usually swing pipe into a swing ell, into the head.

    I'm thinking more of the homeowner lightweight lawn tractor mowers. Some mammoth ZTR could be a different deal.

    My concern with head placements were more about how much leeway was needed for the guys working a steel-blade edger.

    4" is enough. All of my lawns are blade edged. No string. I would prefer 6" to minimize back spray onto sidewalks. The systems that overspray onto hard surfaces are usually placed too close to them.

    it seems to me distance is not an issue other than to avoid edging damage, and, so far out as to leave a dry spot.

    one mentor told me to keep a "closed-fist distance" between head and concrete.

    when using swing joints, dont position the head over the pipe, or down force will break the pipe....same reason i personally dont care for threaded cut-off risers

    4" is enough distance between driveway or sidewalk here in SW Florida.
