I have heard that Exmark is one of the preferred commercial brands. The landscaper who mows several yards on my street uses this equipment in the zero turn capacity. Thanks.For a 1/4 acre, any flavor of MTD would suite your needs. If you’re going to be racking up some hours doing the neighbors turf, then Id buy once cry once and go at least half commercial. A hyrdro 44” would be a good size for your yard but not too small for an acre. Gravely, exmark, hustler etc are some brands to pick from.
