Here’s what I had to say then and still agree:
I have the King Kutter 30" scoop which I use on my NH TC29D, which weights about 2500lbs. It works real good - now. I had to file down the pins to get them to fit my 3pt arms. The first time I tried to use it, it wouldn't dump. With it full of dirt, there was too much resistance and the trip lever wouldn't slide. The bolt that the bottom of the trip lever slides against was too tight and wouldn't allow the roller that goes over the bolt to roll. It's not a very precision fit and I'm not sure if they intended for it to roll or slide, but I modified it so it will roll. I removed it, greased it real good, and put the bolt back on and didn't tighten it down as much so the roller can roll. I also put a piece of treated lumber in the top brace so the pull cord will stay back a little farther, creating a better angle so the pull cord (use nylon so it will slide easy) will pull back on the top of the trip lever a little more, rather than straight up. Now it works great. It still doesn't hold a whole lot, so the 24" would probably be a mistake. I got mine at Quality Farm and Fleet. King Kutter stuff seems sturdy, but they don't pay a lot of attention to detail. My brother bought one of their bush hogs and had to make minor modifications to the 3pt arms to get it to work right, but now it works good.
I would like to modify the trip handle so I could do it without a rope like MikeFla did. I have never had a need to reverse it, I even robbed the pins for something else, so I would have to swap the pins from front to back if I ever did. It’s definitely a very valuable attachment for the money. I expect to get a lot more use out of it this summer.
