A modular drive arrangement for adjustable beds, and the like, comprises interchangeable motor drive units, and manual crank units. The motor drive units have an output shaft at one end, with a coupling that releasably connects with the controller shafts of the bed to manipulate the adjustable sections of the bed. A first, quick-disconnect latch member is located on the bed frame, and mates with a second, quick-disconnect latch member on the opposite end of each motor drive unit to support the motor drive units on the bed frame. The manual crank units have a coupling at one end, which releasably connects with the controller shafts to rotate the same. The opposite end of each manual crank unit includes a bearing, with a third, quick-disconnect latch member thereon, which also mates with the first quick-disconnect latch member to support the manual crank units on the bed frame, whereby even relatively unskilled personnel, without tools, can remove a motor drive unit from the bed for off-site repair, and replace the same with a manual crank unit to insure uninterrupted operation of the bed, without disturbing the patient.
