Abstract: A mobile trailer having an easily raisable and lowerable ground engaging scraper/leveler planar type plate that a single user can raise and lower by a lever arm. Various spring type members allow for the plate to be easily moved upward and downward, and the plate can be locked in a raised position. The trailer can be easily towed behind small tractors and all terrain vehicles(ATVs). Another embodiment allows the plate to be easily raised and lowered by a single arm having one end pivotally attached t a support frame on the mobile trailer. The arm can be slid into side catches so that the plate is at selected heights as needed. Another embodiment allows for a barrel to be pivotally attached to the frame so that raising and lowering the arm allows for a filled barrel to be turned upside down discharging any contents in the barrel.
