I'm bidding an 11 acre complex. 18 buildings but only 140 units. Subtracting the buildings from the total sq. ft. I'm figuring I've got somewhere around 8 acres actual cutting. Since I'm new to this I have no idea what my cutting time is. I purchased a new 52" Toro z mower and a 40" toro wb w/sulky late last year. I haven't run any large yards yet. Each unit has double entries on each side of building. Lots of walks and trimming, but otherwise property is wide open. Is $1500 a wk way high for cutting, trimming and blowing? Also should bagging be added on? How long should it take to cut an acre on this equip? Thanks for your input.
