Ive got a box scraper from TSC. Made by Tarter... It does what it needs to do for my residential yard and I wouldn't hesitate to use it anywhere behind my 2650. I cant envision needing anything heavier for this particular tractor. Ive got hundreds of hours on a box scraper via my employment building landfill cells.
My rear blade and land plane are Woods. For no other reason than timing and convenience when I purchased them. I forget the model on the rear blade, but it does tilt and side shift.... Its decent and has served me well spreading ground asphalt and plowing snow.
My Tiller is from TSC, also made by Tarter. It too does what it needs to do behind my tractor.
My Landscape Rake is EA.... Bought specifically from EA because the quality to dollar ratio was much higher than anything I could get locally. If I had to do it over again, all my attachments would be EA.... They've put a fair bit of thought into their stuff in relation to everything else out there, and do it at a much better price point.
