1. A baler implement comprising:
a housing defining a twine storage box;
a door panel positioned in a substantially vertical orientation relative to the housing and moveably attached to the housing for movement between a lowered position for enclosing the twine storage box and a raised position providing external access to the twine storage box; and
a linkage system having a first link and a second link each interconnecting the door panel and the housing, wherein the first link and the second link maintain the door panel in the substantially vertical orientation relative to the housing while moving between the lowered position and the raised position.
 
23. A linkage system for attaching a door panel to a housing of a baler implement, the linkage system comprising:
a first link including an L-shape having a first leg portion configured for rotatable attachment to the housing, and a second leg portion configured for rotatable attachment to the door panel, the first leg portion and the second leg portion of the first link joining together at a first link vertex;
a second link including an L-shape having a first leg portion configured for rotatable attachment to the housing, and a second leg portion configured for rotatable attachment to the door panel, the first leg portion and the second leg portion of the second link joining together at a second link vertex; and
a connection link having an upper end rotatably coupled to the first link proximate the first link vertex, and a lower end rotatably coupled to the second link proximate the second link vertex;
wherein the first link and the second link are operable to maintain the door panel in a substantially vertical orientation relative to the housing while moving between a lowered position and a raised position.
