A mower deck assembly which inverts to enable servicing of the mower blade and underside of the deck from above without removal of the assembly from the power unit. Deck support arms are pivotally connected to the power unit and deck and can be elevated to permit tilting of the deck beyond a perpendicular to the terrain. Terrain engaging deck support outboard of the deck pivot connections develop a gravity moment retaining the tilted position when they are engaged with terrain outboard of the pivot connections. Drive coupling is maintained by a continuous loop link between drive shafts coaxial with the pivot connections at the drive unit and at the deck.

A mower deck assembly for mounting on a drive unit outboard of the drive unit having a fore-and-aft axis along which it is adapted to be advanced comprising: a deck having a generally planar major body portion adapted to be generally parallel to the terrain to be mowed when in the mowing position; a rotary mower blade mounted for rotation in planes parallel to the major body portion of said deck on the mowing side of the deck most proximate the terrain when in the mowing position; a linkage for supporting the deck from the drive unit outboard of the drive unit; a first pivotal connection between said linkage and the drive unit having a first pivot axi parallel to the terrain to be mowed; a second pivotal connection between said linkage and said deck having a second pivot axis parallel to said first pivot axis; means to raise said deck and said linkage while mounted on the drive unit whereby a radius from said second pivot axis perpendicular to the drive unit supporting terrain is at least the distance between said second pivot axis and a plane normal to the major body portion of said deck, parallel to sid second pivot axis, and passing through the portion of said deck assembly most proximate said drive unit when said deck is parallel to the terrain in supporting said drive unit; means to rotate said deck, while mounted on said drive unit and raised, around said pivot axes through an arc to position said major body portion of said deck at or beyond a perpendicular to the terrain to a servicing position to expose said blade and the major body portion of said deck on the mowing side for servicing from above; and means to maintain said deck in the servicing position.
