OK here is an excersise for the commercial guys out there. I'll give some measurements for a medium sized subdivision we maintain over here. Price for mow and trim only.(We do full service on this site but don't worry about that for now) Don't worry about converting to Australian dollars, I'll work all that out. The person with the closest estimate will win an autographed photo of my truck. Measurements are as follows. Mowing:- 12 acres or 522720 square feet Trimming curb,footpaths and garden beds:- 32808linear ft. Terrain:- mostly flat,but 1 embankment to mow,nothing serious. Turf species:- Greenless Park Couch. Mowing height:-2 1/4 " Equipment used:- Walker MT26 48"ghs deck.Atom blade edger, Solo trimmer. All grass is bagged,but dumped on nearby vacant lots. If you need to see pics of this site,go to Guidos equipment pics. They are fairly representative of the site. I look foward to seeing your estimates.
