Now put it on a ripper in the fall and you can triple that so now you are at over $1500 for fuel.

$5600 (Ez 250/Ez Steer)/$1500=3.75 years.  Not too  bad eh?

again, you never said you only had 3 acres to cover.  point is it will pay for itself in fuel, each person will be different.  hats off to you for running 2 foot on a 50 ft FC all day.  Lot of guys get some older guys to run stuff and they are not that good.  So if it don't save YOU that much thats fine, but it DOES for some.
