I use a 48''Exmark hydro with mulch kit. With the 1/3 rule out the window for over half of last year I could walk faster than I could cut.(tring to get a good finish) I double cut some lawns. This was still faster than bagging + dumping. Could I go faster, double cut using sulky and get a good finish cut? Do you go slower when you use mulch kit (versis side discharge)on dry lawns?
