ksgrassguy,
Just a reminder......be sure to measure that Gravely Pro-Turn 152 since the 2012 product catalog states that the Overall Width is 67.75"(a little over 5.5 feet). I know the discharge chute stores on top of the deck and I haven't measured mine yet to see how tight(or if it would even fit) a 5' wide trailer would be. If that spec is including the discharge shute you may be OK, otherwise you may have to go to a 6' wide trailer.
