Abstract: A self-propelling work vehicle for forward and reverse drive includes a handle unit attached to the vehicle body for a first shift movement along a first direction with a neutral position and a second shift movement from the neutral position along a second direction intersecting the first direction. Forward drive speed or reverse drive speed is determined based on the first shift movement. A guide unit attached to the vehicle body includes a maximum forward speed guide member for defining a shift movement end of the handle unit determining a maximum forward speed of the forward drive speed, and a neutral guide member for guiding the second shift movement of the handle unit from the neutral position defined as a starting position. The maximum forward speed guide member and the neutral guide member are positionally adjustable independently of each other.

Abstract: A ride-on mower with a mower unit attached to a frame unit includes a headlight housing extending in a transverse direction of the vehicle body over the width of the frame unit and fixed to the frame unit forwardly of a front end of the mower deck. A right and left pair of headlight units are housed in the headlight housing. Light passage portions are formed in opposite end portions of the headlight housing for directing light coming from each of the headlight unit to the side and/or to the rear toward a direction of the front end of the mower deck.

Abstract: A work vehicle including a control device for moving an implement through a mechanism including an adjustment mechanism for locking the work implement unit with a predetermined stroke position including a rod, a cam engaging unit mounted on the rod and a cam for producing rotation with the cam engaging unit. The cam retains the work implement in a retaining position through first operational movement of the control device for moving the work implement unit from a basic position to a far side position beyond the retaining position and then returning the work implement unit to the retaining position, and allows the work implement unit to return to the basic position through a second movement control device.

Abstract: A method and apparatus for selecting and mixing electronic signals. The circuit has an operational amplifier and two or more ganged, tapped-resistors in which the tap divides the resistance into a first and a second resistance. The tapped-resistors are connected so that either the first or the second resistance provides the effective input resistance for that signal at the operational amplifier. The second resistance of one of the tapped-resistors provides the output resistance for all signals at operational amplifier. As the tapped resistors are equivalent and their taps ganged, when the signals are mixed, those signals whose effective input resistance at the operational amplifier is selected to be the second resistance have unit gain, while those signals whose effective input resistance at the operational amplifier is selected to be the first resistance have a gain equal to the second resistance divide by the first resistance.
