Stuttering Bill

Stuttering Bill is a robot (full name William D-746541-M Maintenance Robot) with many other functions. He plowed Tower Road all the way up to the edge of the white lands, where the snow ended and the roses began. He gave Roland, Susannah and Patrick a ride on his snowplow for many miles, taking them closer to the Dark Tower.

Stuttering Bill was also the nickname of William Denborough, one of the central characters in King’s novel It.
