We have a property that has about 200,000 sq feet of grass. The problem is it is 71/2 feet wide with trees in the center of the grass with tree circles. It take 3 guys, 6 hours to mow the property with 21" mowers. You have to make 5 passes to mow each section. I am trying to figure out if there is a faster way to mow. The other landscaper used a 36" mower, but the people complained about the mower sucking up the bark in the tree circles. These strips of grass are between the sidewalk and curb. It took us 7 hours with 6 guys to mow and edge the property. The development has 350 homes. Before any one asks the question, yes we are paid well for the job, but it is very tiring at the end of the day. I figure we walk 12-18 miles each of us. Any suggestions????
