Abstract
Work vehicle includes an operation lever pivoting forward and backward stepwise through a plurality of operation positions; and a detent type retention mechanism holding the operation lever in each of the operation positions. The retention mechanism includes a coupling member coupled to the operation lever; and a retention member holding the operation lever via the coupling member. The operation lever and the retention mechanism are provided separately from each other, aligned in a direction intersecting with a pivot support shaft of the operation lever. The operation lever and the coupling member are reciprocally connected via a linking mechanism.
Claims17
A work vehicle comprising:
- an operation lever configured to pivot about a pivot support shaft between a plurality of operation positions;
- a detent retention mechanism releasably retaining the operation lever in each of the operation positions;
- a coupling member;
- a retention member;
- and
- a linking mechanism connecting the operation lever to the detent retention mechanism,
- wherein the operation lever and the detent retention mechanism are at least one of:
- separate from one another;
- and
- spaced from each other;
- wherein the detent retention mechanism and the operation lever are spaced from each other in a front-back direction, and the detent retention mechanism includes recesses structured and arranged to be engaged and act as detents at a point spaced from the operation lever in a front-back direction to provide step-wise retention such that the operation lever pivots stepwise through operating positions,
- and wherein the operation lever is constructed and arranged to move in an operation direction oriented forward and left or right while the coupling member pivots in a front/back direction.

A work vehicle comprising:
- a pivotally mounted operation lever having a user-grippable portion and pivoting about a first pivot axis;
- a pivotally mounted coupling member spaced from the operation lever and pivoting about a second pivot axis;
- a detent retention mechanism coupled to the coupling member and releasably retaining the operation lever in each of plural operation positions;
- a linking mechanism;
- a first movable connection connecting the operation lever to the linking mechanism;
- and
- a second movable connection connecting the coupling member to the linking mechanism,
- wherein the first movable connection is spaced from the first pivot axis by an amount that is less than an overall length of the operation lever and the second movable connection is spaced from the second pivot axis by an amount that is less than an overall length of the coupling member;
- wherein the detent retention mechanism and the operation lever are spaced from each other in a front-back direction, and the detent retention mechanism includes recesses structured and arranged to be engaged and act as detents at a point spaced from the operation lever in a front-back direction to provide step-wise retention such that the operation lever pivots stepwise through operating positions,
- and wherein the operation lever is constructed and arranged to move in an operation direction oriented forward and left or right while the coupling member pivots in a front/back direction.

A work vehicle comprising:
- a support member;
- a first operation lever pivotally mounted to the support member and having a user engageable or grippable portion;
- a second operation lever pivotally mounted to the support member and having a user engageable or grippable portion;
- a pivotally mounted coupling member spaced from the first operation lever;
- a detent retention mechanism coupled to the coupling member and releasably retaining the first operation lever in each of plural operation positions;
- a linking mechanism;
- a first connection connecting the first operation lever to the linking mechanism;
- and
- a second connection connecting the coupling member to the linking mechanism,
- wherein the first operation lever operates speed changing of the work vehicle and the second operation lever operates a work device of the work vehicle;
- wherein the detent retention mechanism and the first operation lever are spaced from each other in a front-back direction, and the detent retention mechanism includes recesses structured and arranged to be engaged and act as detents at a point spaced from the first operation lever in a front-back direction to provide step-wise retention such that the first operation lever pivots stepwise through operating positions,
- and wherein the first operation lever is constructed and arranged to move in an operation direction oriented forward and left or right while the coupling member pivots in a front/back direction.
