Thanks for all the input, I found out that the trailer in the video has a horizontal tongue as it was fitted with surge brakes, that's why the tractor in the video was fitted with a vertical post from the drawbar, it was a solution to enable the use of the surge brakes.
The manufacturer normally manufactures them with a clevis connection that it dropped to a typical tractor drawbar height. I'm putting my order in next week for a dropped clevis, 8' long dump box, walking beam 4 wheel version, no surge brakes to use behind my L and MX tractors. I will be just using rear remotes to operate the onboard cylinder for the dump box. It's going to be a busy few winter and spring month's winching out and transporting fallen timber.
