Redently bought a L3400 w/ loader. One function for this machine is to keep the horse paddock and riding arena in good shape. Paddock is on a slight grade, and dirt tends to wash down towards a drainage area. I want to blade and periodically bring the loose dirt back up. Seems like box blades are the most common. Is that still the best choice, or is a good heavy straight blade (not an el cheapo) a better route. Not sure how deep a box blade can dig, not only limited by weight but also by the box factor. Appreciate any input & suggestions. Gary
