Got one of them fancy zero-turn mowers a while back. Only took me half the morning to realize the dang thing can turn on a dime but still runs like a stubborn mule if you don't oil it right. Sometimes the new ways ain't all they're cracked up to be, but I'll give this critter another shot. Any of y'all got tips on keeping these machines happy and humming?
