Thanks guys,
I think that $200.00 for this job might be a little light

. I told the customer that I would charge him $75/hr and $1/mi haul rate (each way). I expect this job will take 6 to 7 hours so the total should be around $695.00. That seems to be in line with what most of have suggested. I am in business with all it's attendant costs (insurance, accounting, taxes etc.) however I cannot afford to turn down jobs that will make me money. The $75 rate for the tractor includes the cost of the machine, interest, depreciation, maintenance, fuel, insurance, labor and profit. The $1/mi haul rate is really a little light but it is what I told him so I will stick with it. The next one will be $1.20/mi each way.
houstonscott, thanks for the link to the tamu pdf. I have seen those before though not one with as current data as that one. I noticed that the mowing rates seemed pretty cheap at $15/acre. I offer tractor shredding as part of my services and have sliding scale based on acreage as a starting point to price a mowing job. If I am doing 200 acres or so with a 150 hp tractor and a 15' batwing I can get down in the $15-$18/acre range, but most of my mowing jobs are 5-25 acres.
