A guard for a constant-rotating drive shaft in an articulated farm tractor in which a pair of universal joints are connected on either side of a sliding coupler in the drive shaft, the guard having a pair of U-shaped members, one member affixed to a wall with a bearing supporting the drive shaft from the engine on the front frame and the other member affixed to a transfer case on the rear frame. The two members are spaced apart a slight distance in the straight ahead position, but a portion of one member nests within the other member during articulation of the tractor.
