Yeah everyone bashes right away. But in places where you don't need manicured results or a lot of debris/hidden roots ECT I would definitely run the string at least the first time to locate issues. Depending on the line cost I could definitely see running this on a beat up mower used for clearing/brush hogging. Or if cutting down a rutted up field, definitely string instead of bashing blades into the dirt all the time. They definitely were not designed to be used as a finishing mower cut. Designed to be in rough ground where things would unalive blades/spindles or even engine cranks.
I will stick to my high lift blades. I could see that system for sandy rocky environment but anything other than that. No I have two trimmers and a brush cutter that can handle the trimming and clearing. Only the best cut quality is customer quality. Don't except anything but the best of the best.
Hmm... I may have to give this Revo6 a try. I have 27 acres of high desert, that's not by any stretch of the imagination flat, to maintain. While I'd be better off using a brush hog, I much prefer the lower center of gravity on my ZT mower. And with all of the small river rocks and other desert "obstacles", having a ZT "string trimmer" might be more effective here than steel blades.
An interesting idea. Maybe this would work better if you could get longer lines and bolt the heads on angled from one another so they overlap/interlock without touching as they spin, that way you aren't leaving mohikans as you go along.
