Abstract: A tiltable steering system for an off-highway implement including a steering column having a steering wheel connected toward an upper end thereof. A tilting mechanism for the steering column defines a generally horizontal pivot about which the steering column moves. The tilting mechanism further includes a gas spring mechanism connected to the steering column for allowing the steering column to pivotally move through a relatively wide range of positions and thereafter be locked in a selected tilted position. A second tilting mechanism is provided between the steering column and the steering wheel for allowing the steering wheel to be adjusted and secured in a tilted position independently of the selected tilted position of the steering column. To further promote ergonomic positioning of the steering wheel, the steering column of the present invention is elevationally adjustable as through telescoping casings which define the steering column.

Abstract: A shift mechanism for a multi-speed transmission of an off-highway implement. The shift mechanism includes an in-line shifter assembly that connects to first and second actuators on the transmission. The shifter assembly is configured to shift the transmission between speed ratios under one-handed control and comprises a first controller that is movable along a monoplanar path of travel and a second controller that is carried by the first controller and is movable between two vertical positions. The shifter assembly is connected to a selected one of the transmission actuators as a function of the vertical position of the vertically movable controller. Back and forth movements of the other controller moves the selected one of the transmission actuators into a position which conditions the transmission for operation in a selected speed ratio.

Abstract: The improved steering mode selector assembly includes a selector member having a slot, a carrier and a selector lever mounted on such carrier. The selector lever is movable along the slot between a first position, a second position and a third position, each of which corresponds with a selected steering mode. The lever is laterally biased in a first direction so that movement of the lever to the third position requires the lever to be manually biased in a second direction. The lever is thereby substantially prevented from being inadvertently moved to the third position.

Abstract: An apparatus for controlling the position of an operating handle includes a plate which couples such operating handle to a device such as a hydraulic valve. The plate includes a detent notch, a shoulder and a control surface. An auxiliary lever is mounted for pivoting movement between a first, engaged position and a second, disengaged position and is maintained in either position by a compression spring. Such compression spring exhibits toggling movement as the lever is moved between positions. The lever includes a pin for engaging the detent notch when the lever is in the first position and the handle is thereby retained in a predetermined position. When the pin is in contact with the control surface and with the shoulder, the handle is retained in an operating position. Movement of a stop mechanism to a position which does not obstruct handle movement also permits the operating handle to move to a "float" position.
