I have been in the business for 7 years now and I have used ratchet straps and tie downs for every piece of equipment on my trailers over the years. ive even laid my rakes and brooms down, and bungied them together to minimize chances of them becoming a flying projectile or obstacle that another drive might have to dangerously maneuver around. Im currently in the process of organizing my trailer for the most efficient traveling and loading/unloading procedures. So far, Ive decided on 2x4's trailer width in front and rear or the rear tire. this will help prevent any back and forth movement. I will take tow straps....yes the heavy duty yellow straps and cut them down to a shorter more manageable length and permanently fasten one end to the trailer and the other will retain its hook. My Exmark has 4 tie down points, one at each corner so this will aid with securing it to the trailer. For my push/walk behinds, ill do the same thing except ill have 1 2x4 in front of the front wheels, and one behind the rear wheels instead of capturing one set of wheels. this should definitely prevent rocking back and forth. ill install D rings on the floor as anchor points for a ratchet strap to go across the deck and secure it that way. I think not only will this help to prevent any injuries in the event of a severe accident, but it will also make loading faster since ill have designated places for everything to go. I will not have a variation from day to day on where my equipment sits on the trailer and thus it will make strapping down the equipment easier and quicker. this, im willing to do to help prevent any unnecessary injury to both myself, and the citizens in which i aim to service. I have also thought about linexing my whole floor board once all the anchor points and retention boards are set into place. thanks for the great site and i have learned alot from you guys.
