I am looking to purchase a Box scraper. I own a Kubota 2920 with a FEL...my question is can this tractor handle a 5 foot BB or should I go with a smaller 4 foot. The dealer I purchased My tractor from has a Howse 4 foot he will sell for $425. But I really like my Woods grooming mower RD6000 and would like a woods gb 60. I am aso under the impression that the "SCARIFIERS" on the Howse may work them-self loose from another post.
