I work alone, currently using a 48" WB (ZTR come spring); Can't see to get past 9 -10 lawns per day level. I'm wondering if my territory is too wide-spread. I radiate out about 5 - 6 miles in each direction from my house, so in total, at least 100 square miles. I have several "clusters" of accounts, but may travel 15 to 20 minutes between the clusters. Is this a good or bad concentration of accounts?
