Not sure about the LS walk-behind unit yet, cuz we're currently only pulling 1 - 1 1/2 inch plugs with all four weights in place. My guys take the TURFCO walk-behinds out everyday and leave the LS walk-behind aerator in the shop. Not sure what's going on there, but I let my guys pick & choose. Go figure. Heck -- we're still using a twenty-year-old Ryan walk-behind......seems they were better built compared to what Ryan offers nowadays.
Our 2 cents
Thanks AmericanLawn. You seem to be one of very few people that don't like the quality of the LS walk behind plugs. Have asked for any feedback from LS as to why this might be happening? Thanks.
