Last week one of my helpers put the Exmark mulching blades on our WB on upside down. He then cut 3 residential accounts. The wavy Exmark mulchers managed to scalp some spots even at 3.5. The lawns looked like crap but I decided not to recut because we would have had to cut at 2.5 to even out the turf. I tried not to let it bother me & went on with the days work. I expected the turf to be browning or unhealthy looking when I arrived at those accounts this week. The turf looked good, green & growing like after a normal cut. We have had little rain, & none of these cusomers waters so WHAT GIVES? I've allways kept blades sharp but this has me wondering if I'm working too hard at keeping that razor edge.
