I have a 9610 with the large floatation tires(35.2 30) or whatever is close. My header looks like the guards are pointing at an angle to the ground(down). Do I need a wedge kit to make this a better angle. It doesn't feed good especially going downhill. I think the header should be tilted back but don't know how. Hope someone can help because if the wind blows and the sun comes out it won't be back to the shop until Christmas.
