We would have done that if we could have gotten a few more trucks, but they are hard to come by.  At 15 miles it was equal.  At 20 the JCB could keep up as it goes 42 mph, but the Fendt took about 5 mins more.  It only goes 35.  The 25 mile haul it was an extra 10-15, but its better than nothing.  We chopped 600 or so acres, about 2000 tons in 2 days.  We kept up with the mower.  We wouldn't have been able to go any faster from a hay moisture standpoint.
