Shiftable control console for tractors

Claim 2

In a tractor having a mobile chassis; steering controls supported by said chassis for controlling the direction of movement of said mobile chassis over the ground; a seat supported adjacent said steering controls for fore-and-aft movement relative thereto; a control console supporting a plurality of operational control devices adjacent said seat, the improvement comprising: mounting linkage interconnecting said control console and said chassis to support said control console for movement relative to said seat, said mounting linkage including forward and rearward, longitudinally spaced pivot assemblies, defining forward and rearward pivot axes, respectfully, about which said control console is pivotally movable, each of said pivot assemblies including a swing arm rotatable from one end thereof about the respective said pivot axis and carrying said control console at an opposing end thereof.

Claim 3

The tractor of claim 1 wherein said control console is movable forwardly and rearwardly from a median position, the movement thereof forwardly of said median position is generally in a longitudinal direction with minimal transverse movement, the movement of said control console rearwardly of said median position resulting in a transverse rotation of said control console to correspond to the predetermined angular rotation of said seat when moving from said tractor operating position to said implement operating position.

Claim 4

The tractor of claim 1 wherein said forward and rearward swing arms extend from their respective said pivot axes in opposite directions to effect a transverse rotation of said control console when moving rearwardly from said median position.

Claim 5

The tractor of claim 3 wherein said swing arms are oriented, when said control console is in said median position, at a predetermined angular displacement rearwardly from a transverse orientation, the extent of forward movement of said control console from said median position being limited to approximately twice said predetermined angular displacement so that the overall forward movement of said control console from said median position does not result in any substantial transverse movement of said control console.

Claim 6

The tractor of claim 4 wherein the movement of said control console rearwardly of said median position involves a pivotal movement of said swing arms toward a longitudinal line passing through the corresponding said pivot axis, resulting in a transverse displacement of said control console, the orientation of said swing arms in opposing directions resulting in a transverse rotation of said control console.

Claim 7

The tractor of claim 5 wherein said swing arms are oriented such that the extent of movement thereof rearwardly of said median position results in a transverse rotation substantially equivalent to the angular rotation of said seat when moved from said tractor operating position to said implement operating position.

Claim 8

The tractor of claim 6 wherein said forward and rearward pivot axes are transversely spaced.

Claim 9

A tractor comprising: a mobile chassis; steering controls supported by said chassis for controlling the direction of movement of said mobile chassis over the ground; a seat supported adjacent said steering controls for fore-and-aft movement relative thereto, said seat also being rotational from a tractor operating position oriented in a forward direction to an implement operating position rotated through a predetermined angular rotation from said tractor operating position to facilitate the observation of the operation of an implement towed behind said tractor while said tractor is moving in a forward direction; a control console supporting a plurality of operational control devices adjacent said seat, said console being independently movable in a fore-and-aft direction relative to said seat; and a mounting linkage supporting said control console from said chassis and having forward and rearward, longitudinally spaced pivot assemblies, defining forward and rearward pivot axes, respectfully, about which said control console is pivotally movable, each of said pivot assemblies including a swing arm rotatable from one end thereof about the respective said pivot axis and carrying said control console at an opposing end thereof, said swing arms extending from their respective said pivot axes in opposite transverse directions.

Claim 10

A tractor comprising: a mobile chassis; steering controls supported by said chassis for controlling the direction of movement of said mobile chassis over the ground; a seat supported adjacent said steering controls for fore-and-aft movement relative thereto, said seat also being rotational from a tractor operating position oriented in a forward direction to an implement operating position rotated through a predetermined angular rotation from said tractor operating position to facilitate the observation of the operation of an implement towed behind said tractor while said tractor is moving in a forward direction; a control console supporting a plurality of operational control devices adjacent said seat, said console being independently movable in a fore-and-aft direction relative to said seat; and a mounting linkage supporting said control console from said chassis and having forward and rearward, longitudinally spaced pivot assemblies, defining forward and rearward pivot axes, respectfully, about which said control console is pivotally movable, each of said pivot assemblies including a swing arm rotatable from one end thereof about the respective said pivot axis and carrying said control console at an opposing end thereof, said swing arms extending from their respective said pivot axes in opposite transverse directions.

Claim 11

The tractor of claim 8 wherein said control console is movable forwardly and rearwardly from a median position, the movement thereof forwardly of said median position is generally in a longitudinal direction with minimal transverse movement, the movement of said control console rearwardly of said median position results in a transverse rotation of said control console to correspond to the predetermined angular rotation of said seat when moving from said tractor operating position to said implement operating position.

Claim 12

The tractor of claim 9 wherein said swing arms are oriented, when said control console is in said median position, at a predetermined angular displacement rearwardly from a transverse orientation, the extent of forward movement of said control console from said median position being limited to a forward angular displacement of said swing arms approximately equal to twice said predetermined angular displacement so that the overall forward movement of said control console from said median position does not result in any substantial transverse movement of said control console, the movement of said control console rearwardly of said median position involving a pivotal movement of said swing arms toward a longitudinal line passing through the corresponding said pivot axis, resulting in a transverse displacement of said control console, the orientation of said swing arms in opposing directions resulting in a transverse rotation of said control console through an angular rotation substantially corresponding to the angular rotation of said seat when moving from said tractor operating position to said implement operating position.

Claim 13

The tractor of claim 10 further comprising a linear actuator coupled between said chassis and one of said swing arms to effect pivotal movement of said swing arms.

Claim 14

The tractor of claim 11 wherein said linear actuator is electrically controlled from a switch mounted on said control console.
