I have had an exmark lazer hp 48 for a while and i just bought a 6X12 tandem trailer. When i pull the exmark on the bag drags so i have to go up the ramp at a 45 degree angle to avoid this. the deck also scrapes the joint between trailer and gate. Is this just going to happen or is there any quick way to pervent. I am pulling with a standard height 1994 silverado 1500.
