Tractor
A tractor, including: a link mechanism fixation-member which regulates rotation of the HST trunnion shaft by abutting the link mechanism; a link mechanism fixation-member operation lever which makes the link mechanism fixation-member about the link mechanism, or makes the link mechanism fixation-member move in a direction so as to get apart from the link mechanism; a brake pedal which is provided at the other side of the left-and-right sides of the step floor; and a link mechanism joining-cancellation mechanism which makes, in a case where the link mechanism fixation-member is abutting the link mechanism, the link mechanism fixation-member move in a direction so as to get apart from the link mechanism when stepping-on of the brake pedal is performed.
1. A tractor, comprising:
an HST;
a frontward/rearward movement pedal which is connected to an HST trunnion shaft of the HST;
a link mechanism;
a frontward/rearward movement pedal rotation-shaft which, with both end parts of the frontward/rearward movement pedal rotation-shaft being respectively connected to the frontward/rearward movement pedal and the link mechanism, rotates in correspondence to swinging of the frontward/rearward movement pedal;
a link mechanism fixation-member which regulates rotation of the HST trunnion shaft by abutting the link mechanism;
a link mechanism fixation-member operation lever which makes the link mechanism fixation-member abut the link mechanism, or makes the link mechanism fixation-member move in a direction so as to get apart from the link mechanism;
a brake pedal; and
a link mechanism joining-cancellation mechanism which makes, in a case where the link mechanism fixation-member is abutting the link mechanism, the link mechanism fixation-member move in a direction so as to get apart from the link mechanism when stepping-on of the brake pedal is performed,
wherein the link mechanism joining-cancellation mechanism comprises a link mechanism joining-cancellation plate which makes, by abutting the link mechanism fixation-member, the link mechanism fixation-member move in a direction so as to get apart from the link mechanism when stepping-on of the brake pedal is performed,
the brake pedal comprises a left brake pedal which corresponds to a brake of a vehicle-wheel at a left side, and a right brake pedal which corresponds to a brake of a vehicle-wheel at a right side, and
the link mechanism joining-cancellation plate comprises a first plate corresponding to the left brake pedal, and a second plate corresponding to the right brake pedal.
2. The tractor according to claim 1 , wherein the link mechanism fixation-member comprises an abutted part which is abutted by the link mechanism joining-cancellation plate, and the abutted part comprises a first abutted part which is abutted by the first plate, and a second abutted part which is abutted by the second plate.
3. A tractor comprising:
an HST;
a frontward/rearward movement pedal which is connected to an HST trunnion shaft of the HST, and is provided at one side of left-and-right sides of a step floor;
a link mechanism which is provided at other side of the left-and-right sides of the step floor;
a frontward/rearward movement pedal rotation-shaft which extends in a left-and-right direction below the step floor, with both end parts of the frontward/rearward movement pedal rotation-shaft being respectively connected to the frontward/rearward movement pedal and the link mechanism, and rotates in correspondence to swinging of the frontward/rearward movement pedal;
a link mechanism fixation-member which regulates rotation of the HST trunnion shaft by abutting the link mechanism;
a link mechanism fixation-member operation lever which makes the link mechanism fixation-member abut the link mechanism, or makes the link mechanism fixation-member move in a direction so as to get apart from the link mechanism;
a brake pedal which is provided at the other side of the left-and-right sides of the step floor; and
a link mechanism joining-cancellation mechanism which makes, in a case where the link mechanism fixation-member is abutting the link mechanism, the link mechanism fixation-member move in a direction so as to get apart from the link mechanism when stepping-on of the brake pedal is performed,
wherein the link mechanism joining-cancellation mechanism comprises a link mechanism joining-cancellation plate which makes, by abutting the link mechanism fixation-member, the link mechanism fixation-member move in a direction so as to get apart from the link mechanism when stepping-on of the brake pedal is performed,
the brake pedal comprises a left brake pedal which corresponds to a brake of a vehicle-wheel at a left side, and a right brake pedal which corresponds to a brake of a vehicle-wheel at a right side, and
the link mechanism joining-cancellation plate comprises a first plate corresponding to the left brake pedal, and a second plate corresponding to the right brake pedal.
4. The tractor according to claim 3 , wherein
the link mechanism fixation-member, the link mechanism fixation-member operation lever, and the link mechanism joining-cancellation mechanism are provided at the other side of the left-and-right sides of the step floor.
5. The tractor according to claim 4 , wherein the link mechanism fixation-member comprises an abutted part which is abutted by the link mechanism joining-cancellation plate, and the abutted part comprises a first abutted part which is abutted by the first plate, and a second abutted part which is abutted by the second plate.
6. The tractor according to claim 3 , wherein
the link mechanism fixation-member comprises an abutted part which is abutted by the link mechanism joining-cancellation plate, and
the abutted part comprises a first abutted part which is abutted by the first plate, and a second abutted part which is abutted by the second plate.
