Abstract: An improvement of a loader work machine is disclosed. A machine body frame includes a frame body having a bottom wall and a pair or right/left side walls, and a pair of right/left support frame members connected to a rear end of the frame body. A cabin is mounted on the machine body frame. A transverse connecting member is disposed rearwardly of the cabin for connecting the pair of right/left support frame members to right/left sides thereof, respectively. A pair of right/left arms are disposed on right/left sides of the machine body frame, with base portions thereof being vertically pivotally supported to the pair of right/left support frame members, respectively. A pair of right/left arm cylinders are provided between the base portions of the arms and the rear portions of the machine body frame for lifting up/down the arms. A hood is provided at the rear end of the frame body and downwardly of the transverse connecting member between the pair of right/left support frame members, for housing an engine.
