Fert/Granular Spreader Advice

that's the one (Polaris). 80 lbs on the reciever is well within the tongue weight design. Support at top by guard makes side torque on reciever minimal. Side thrust of trailer tongue would be much greater. Stopping a loaded trailer in a turn would generate many times the force. Isn't the reciever built better for this work than the sheetmetal tailgate? Looks like ajdillion has the spreader mount I was talking about.
