O K I have seen the video for the plugger and read the specs on coverage per hr. understand the points about hills and obsticles taking more time than flat and wide open. The question is which is more productive? Single pass with a plugger pl800 or double passes with Lesco/clausen split drive? looking for real world experience from some who have used both; maybe on same properties for acurate comparison. thanks ps: I know zplugs or big tow behinds are faster just talking walk behinds here.
