Well thought I would post since I used my accelerator for the first time. Got the 4.15 for a 36" eXmark. Very pleased with the catcher. Looks to be very well built as far as all the welds are concerned. Very, very light, could not believe how light it was empty and for that matter, even when packed full. Hooked right on out of the box, no mods at all. When using it, it packed clippings and leaf debris in their so tight it was like dumping out a brick of grass. It did come right out though without any excessive shaking or knocking of the catcher. Very impressed with the product and the service I received from the guys at Accelerator. Would definitely recommend them and if needed, I will use Accelerator again without a second thought.
