I trailered my JD 5103 / MX6 on a 22' GN around 10 miles and back a few months ago without fastening it down with anything. Just dropped the bucket and mower down, put her in Park and headed down the road :laughing:
(I couldn't find my straps and needed to get the mowing done... so I risked it on some back county roads.) I won't ever do that again, as I barely drove with my eyes on the road. They were mostly in the rear-view making sure my tractor wasn't moving! :laughing:
