ABSTRACT:
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.
