Good at least I am not the cheapest on this anymore with a mow price of $170. I have a school up for bids this week. All total 80 acres of turf. Roughly 2 blocks by 12 blocks - all close. The last 3 years they had a guy hired to use there JD 72 and he used his exmark 72, they paid him $9 / hour to mow plus extra of some sort to use his machine. As dry as it was last year he still squicked close to $21,000 out of the school district. Myself, thinking trim as needed, where seen by people ever time, if your good with a mower very little blowing, only part to bag is one ball field and football field. Everything is open. Sure alot walks, curbs but nothing our 40 acre complex has not offered us. THing is I want to use our wams. Open area we can make time. Stick the 72"s out there in there places, bag with the 52"s. I honestly think if I have a full crew there, start to finishone day. maybe a few hours the next to finish. Man hours you may ask - I am thinking 35-40 man hours. Spring will be longer if we get rain due to wetter heavier grass, july should be a dust bowl, september with days getting shorter may increase visit time due to constraints of mowing while in school. Cost - not going there as you guys already think I am low so I'll let you people venture a guess.
