If you average 3' of cut per acre, that's 4,840 CY of soil to move per acre. Not sure how large your bucket capacity is, but let's assume it's 1/2 CY, that's 9,680 bucket loads per acre. How long will it take you to dig a bucket of clay, move, dump and return? 1 minute? And assume you are getting 50 minutes of production per hour - that's 50 loads/ hr. 9680/50 = 193 hours per acre times 2-3 acres (2.5) = 482 hours.
Of course, you need to plug in the correct values - but these numbers probably are fairly close.
I didn't take the time to look up your fuel burn per hour, but it's probably 2 - 2.5 gal. Add a bit for oil and your wet costs are $10 an hour. Not including anything else - wear & tear, etc.
Do what you want - just helping you to picture the time involved. Have fun!
