The drawbar comprises a first portion coupled to the frame and a second portion. A joint comprises a first bracket comprising a protrusion. The protrusion defines a first aperture. The first bracket is coupled to one of the second portion of the drawbar and the earth-working tool. A second bracket defines a channel configured to receive the protrusion. The channel defines a second aperture on a first side of the channel and a third aperture on a second side of the channel. The second bracket is coupled to the other of the second portion of the drawbar and the earth-working tool. A fastener is positioned through the first aperture, the second aperture, and the third aperture. The protrusion is configured to move laterally in the channel.
