Many years ago, when I had my 550G, I had purchased a Mann pin on rake for that dozer. Extremely well built unit. I got good enough with it that I could transport logs across my jobsites by flopping the rake over the log, backing up to pinch the log between the rake and the blade, moving forward and then lifting the pinched log into the air. It was fast and slick. The rake was always easy to pin on and off. That went with the dozer when it was sold off.
When I purchased my PC200, I ordered a Mann hydraulic thumb and rake combo that I still have. Excellent attachment that has served me well. Too bad Mann went out of business some time ago. They were in the Pacific Northwest. If you could find one used, it would likely be a great choice.
