Hi Shawn!

The mounting holes on the Demco Trailer Coupler - Cast - Adjustable Channel # DM14040-81 measure 2" on center (which I included a quick diagram of). It is typically used with something like the 6-Hole Adjustable Channel Bracket - Weld On - 12" Tall - 21,000 lbs # DM66134.

Do you know how your mounting holes measure? We probably have other options if it isn't the same as this.

Hey Shawn, did you get a chance to check the bolt hole spacing on your Easy Lawn hydroseeder? Once you know that measurement, we can see if this coupler or another option will line up right. Let me know what you find—I’m happy to help narrow it down.
