ABSTRACT:
An "L" shaped mud pit longitudinally and horizontally hinges at an upper edge of a wall panel thereof to a portion of a vehicle frame, or an extension thereof, such that when lowered it is in ground-supported, horizontal position convenient with respect to the hole to be drilled and when raised it is in a storage-transport vertical position in which it is in line with the adjacent side of the vehicle, and its rearward portion is above the vehicle rear tire. A centrally located divider wall panel enables liquid to travel from the rear of the mud pit forward and then back again to the rear thereof where a removable extension to the mud pump intake pipe is located. Screens, adjustable leveling pads, and drain and cleanout plugs are also provided.
