Hey Plott
In that last pic, it looks like you have one strap running from the machine, through a couple Trailer Tie Downs, and then back to the machine. (Can't see it all, I'm just assuming)
Anyway, I was stopped by the local RCMP one day and was told that I HAD to use at least 4 straps to tie a machine down (Machine=4 or more wheels)
If I'm wrong on how you have that rigged, please disregard message.
Just thought you should know.
