The device has a joint axle running in a travel direction and arranged at a frame (1) of a distribution machine by a joint arrangement. The axle is provided between a parking position and a non-parking position of pivotable parking supports (3). The supports are locked in the position by a locking element. A tension spring (17) is assigned to the supports for fixing and/or locking the supports in the positions, and holds the supports in each position. The locking element is arranged at distance to the spring. A foot actuating element at the supports adjusts the supports in the positions.
