Abstract: A mobile computer work station for a personal computer is disclosed comprising a wheel mounted cabinet (12) for enclosing the computer CPU therein and supporting a computer monitor thereon. A concave vertical partition (18) mounts to a forward side of the cabinet (12) and defines a three sided user station providing improved acoustic and visual isolation to the user. A window (120) extends through the partition (18) and receives the screen of the computer monitor therein. A bezel plate (26) affixes to a forward side of the partition (18) and surrounds the window (120). A lower portion (122) of the plate (26) protects the controls to the monitor there behind from unauthorized tampering. A speaker cavity is defined behind the lower plate portion (122) likewise isolated thereby from unauthorized contact. S-shaped support bars (14, 16) structurally connect cabinet (12) and partition (18) and support a keyboard support plate (20) upon bar segments (98) within the concave partition (18). A second bezel plate (24) attaches to a top surface of plate (20) to retain a touch sensitive keyboard component thereon.

Abstract: A foot-actuated mower deck lift mechanism for a riding lawnmower comprising first and second foot pedals for adjusting the cutting height of the mower deck. The foot pedals are suitable for engagement by an operator's foot to raise, latch and lower the cutting deck. The first pedal is connected to a lift linkage to adjust the height of the cutting deck upon actuation of the first pedal by the operator's foot. The second pedal is configured to automatically latch the mower deck into a raised transport position when the first pedal is depressed a preset amount, and to unlatch the mower deck upon actuation by the operator's foot. An adjustable pin-actuated height index mechanism is implemented to provide a plurality of predetermined cutting heights for the mower deck.
