The Steamroller is a heavy machine featured in "Don't Rain on My Ed." It is one of the machines in the construction site. As the name suggests, it is a large yellow steamroller.
It is seen when Ed and Eddy go through the construction site on their way to get jawbreakers from the candy store's customer appreciation day sale. They end up running into it, and when Ed yanks Eddy out of the steamroller, Eddy accidentally turns it on and it ends up running them over. The steamroller was seen moving on after running over Ed and Eddy, and it is unknown if it stopped while still in the construction site or if it ended up rolling out of the construction zone until it stopped somewhere or even if it might have rolled into the creek.
