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.
Claims20
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 retention mechanism are at least one of:
- separate from one another;
- and
- spaced from one another from each other.
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 an over length of 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.
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.
