Farmboy, figure out what it will cost you to own and operate the machine. For yearly cash flow I figure the principal and interest payments, interest on the money you have already paid on the machine, your extra fuel costs (1-1.5 gal. per acre maybe),and repair costs (guess 6-8 per acre depending on crops and conditions). For tax purposes, the depreciation will offset the principal payments somewhat. Don't forget you may need an extra person to replace what you previousl did with the custom cutter. Of course, these costs may also be balanced by getting the job done when you want it done, how you want it done, and not when the custom cutter can get there. The machine should be able to easily handle 6-700 acres depending on your crop mix and length of harvest season. I cut around 550 soys (20'),450 corn (6-30) with an R50 quite easily. More if deer hunting didn't get in the way. Check out a 50,or 52, same basic machine, but more engine. You may also be able to do some custom cutting yourself, though I sometimes question the economics of this due to the care some customers put into their crops-lotsa weeds. Good luck, Rob.
