Three and a half acres if I calculate that correctly. I'm with Richard. Probably in the $150 - 200 range myself, depending upon the amount of trimming/weedeating. If it was mow - only and not overgrown, I'd probably shoot for $150. BTW, I would be using a 60" ZTR.
3 1/2 acres huh - I bid about 3 accounts this year with 3 to 4 acres at $15 per acre plus $20 unload fee ($15 for every acre or part of acre - ie 3.5 acres is $15x4 = $60) -
I use the above formula up to 6-8 acres, and after that there is no unload fee.
So far out of 16 bids on commercial jobs from 1.5 acres to 22 acres I have landed 2 - count them TWO
One is the 1.5 ($15 x2 = 30 + $20 unload = $50)
#two is 17 acres at $249, and was informed I barely won.
The good new is that the 17 acres is wide open, no trees, no trimming, just mow - (2.5 hrs is my estimate in time - me-myself-and I) which will gross me about $100 per hr. one machine.
