I've joined to share ideas for my garden tractor fleet and they are all green & yellow. 4 diesel 455's 5- 420's and a few others. I enjoy building / re-building implements.
Welcome to the site John. That scraper is very impressive, I've not seen it before, nice job! If you;ve got build pictures I'd be intrigued to see them.
BTW, respect for having 4x455s, they dont come cheap!
I got tired of getting off and on the tractor to change the snow blower chute deflector, so I added a 12v linear actuator. You control the actuator from inside the cab with a DPDT co. momentary toggle switch
