Tandem housing

A tandem housing for a work vehicle, the tandem housing having a fore-aft dimension and a lateral dimension perpendicular to the fore-aft dimension, the tandem housing comprising:

• an exterior multi-layer first wall, the first wall comprising a main plate and a reinforcement plate positioned on the main plate in face-to-face relation therewith so as to reinforce the main plate,
• an exterior second wall, the first wall comprising a propulsion input hole configured to receive a propulsion input of the work vehicle, the second wall comprising a first propulsion output hole configured to receive a first propulsion output of the work vehicle and a second propulsion output hole configured to receive a second propulsion output of the work vehicle, the first and second propulsion output holes positioned on opposite sides of the propulsion input hole relative to the fore-aft dimension of the tandem housing,
• an exterior rim coupled to the first wall and the second wall so as to provide a periphery of the tandem housing laterally between the first wall and the second wall relative to the lateral dimension of the tandem housing, the main plate, the reinforcement plate, and the rim cooperating to provide a weld groove, and
• a weld positioned in the weld groove in contact with the main plate, the reinforcement plate, and the rim so as to attach the main plate, the reinforcement plate, and the rim to one another.
