Yup it’s a Curt front tow receiver license plate mount. Thing is built like a Sherman Tank, now when the all weather toll box arrives I just have to bolt it on.
I leave my heavy hitch on most of the time sometimes with no weight. The hitch’n can works much better with the receiver on the tractor. On recycling weeks I put a mile on the tractor just hauling the cans up and back since recycling is every other Monday and trash is Every Wednesday.
