All the brand names are generally decent quality...if you don't mind used equipment you can probably get both a decent box blade and a quality rear blade for less money than a single new unit of similar quality...
usually the heavier the better when it comes to grading implements...sized for your machine...
Look for one that is a high back model with a hinged tailboard. Mine also has a lever that operates the rippers, model GBS72R, weighs 647 pounds:Hello all. I badly need a 6' box blade/scraper and cannot wait 3 months for one...as much as id like to have an EA.
Whats the next best thing?
