A drill comprising a frame supported for movement over the ground in a forward propel direction and a rearward propel direction, a mast mounted on the frame in a generally vertical position, and a drill head moveable up and down the mast. The drill head is selectively engageable with the upper end of a drill pipe so that the drill pipe is raised and lowered out of and into the ground when the drill head moves up and down the mast. The drill further includes a crawler drive for moving the drill in the forward propel direction, a motor for moving the drill head to cause drilling, and an operator's cab positioned on the frame adjacent the mast. The cab includes a first console and a second console spaced from the first console, controls on the first console for operating the forward propel drive, and controls on the second console for operating the drill head motor.
