I have three small yards and one subdivision common ground. The yards take about 1/2 hr and the common ground about 2 hrs with my 21" mower. Two yards have 36" gates These are all weekly cuts and I'm trying to pick up more business. My 21 is only a few weeks old. I have my eye on a 32 Ferris single hydro walk behind....guy is asking 1300 for it. Do I pull the trigger on the hydro or just continue to mow until I have more accounts? What would you do?
