Next spring I want to get a Box scraper. What size is good for a L3800? I want one to make a lawn, right now its rocks timothy and wild roses etc. Was going to do it this fall but I was afraid of the frost hitting soon, oh well I guess not.
Five feet is the correct width. Buy the heaviest Box Blade you can afford. 600 - 700 pounds would be my recommendation for the rocky soil in Mass.
As you have a Backhoe, perhaps you can get by with a Ratchet Rake on the FEL bucket ($350) rather than a Box Blade, which will require you to remove the Backhoe.
Photo #1 is my Bush Hog (brand) Rollover Box Blade, 587 pounds. Photos #2, #3, #4 are the Ratchet Rake.
