I don't need the swinging part for anything but I've been wanting to put one of these on for years. There isn't much to this, it's just a bolt up job. The clevis assembly went on easily. I made more work out of it for myself though, by using a riveted drawbar hanger off an 801. I knew when I bought it that it had to be shortened to fit the N. I cut a 1 3/8" crescent shaped piece out of the middle and stuck it back together. Also I reworked an old bar into a 1x2x18 w/shackle for pulling and have a 30" bar w/offset and hitch ball for the trailers.
Besides being a safe way to pull, it doesn't interfere with any of the implements I use. The bar is removable in seconds and can be easily replaced with one of a different configuration.
