Ok everyone, I measured this one today. Lets see how you would bid on this one. Drive time a little long, 40 miles one way. A drawback for sure but wait this is a twice a month cut, no hedges or flowers or bushes. Also could be a way in to other Walmart superstores. Also there is a lot of other prospects in the immediate area. Total sq ft 85,332. 39,408 sq ft can be cut with rider no problem. Its flat and has no obsticles. 30,612sq ft to be cut with wb 21" as it is 18" wide strips. The other 15,312 is the problem. Its a bank, 22ft from bottom to top. May be able to push, more than likely string trimmer. This prop has 3,259 ln ft to edge. And 454 ln ft to cut with string trimmer along a chain link fence. All in all without a pic the best I can help is that 39,408 sq ft is a difficulty factor of 1. 45,924 a factor of 3.
