Now that my mowing season is over here in upstate NY, I am looking for ways to make next season better. Mainly, I am considering a mulch kit for my 60", 25 HP, Exmark Lazer with the Series 4 deck. For those with experience with mulch kits (Exmark primarily) in northern grasses, what are your overall feelings as to how well they function on regularly (weekly) maintained lawns. Do any blades perform better than others when used with a mulch kit? Factory or after market? I am a solo operator so adjusting my mowing style is easy, if necessary, to optimize the functioning of the kit. Just looking for accurate, honest input, thanks.
