Abstract
A kickdown shift control device for a work vehicle. The work vehicle has a transmission with at least a range and a lower range having more power. The kickdown shift control device comprises a shift switch for switching a travel direction of the work vehicle and for shifting the transmission. The shift switch has a rocker with a forward position, a reverse position, a neutral position, and a kickdown position for shifting the transmission from the range to the lower range. The rocker is positioned in the forward position, the reverse position, and the neutral position with a first force. The rocker is positioned in the kickdown position by pressing the rocker towards the forward position with a second force that is greater than the first force.

A kickdown shift control device for a work vehicle having a transmission with at least a range and a lower range having more power, the kickdown shift control device comprising:
- a shift switch for switching a travel direction of the work vehicle and for shifting the transmission, the shift switch having a rocker with a forward position for changing the travel direction of the work vehicle to forward, a reverse position for changing the travel direction of the work vehicle to reverse, a neutral position, and a kickdown position for shifting the transmission from the range to the lower range;
- wherein the rocker is positioned in the forward position by pressing the rocker towards the forward position with a first force, the rocker is positioned in the reverse position by pressing the rocker towards the reverse position with the first force, the rocker is positioned in the neutral position by pressing the rocker towards the neutral position with the first force, and the rocker is positioned in the kickdown position by pressing the rocker towards the forward position with a second force that is greater than the first force.
A work vehicle comprising:
- a transmission with at least a range and a lower range having more power;
- and
- a kickdown shift control device comprising:
- a shift switch for switching a travel direction of the work vehicle and for shifting the transmission, the shift switch having a rocker with a forward position for changing the travel direction of the work vehicle to forward, a reverse position for changing the travel direction of the work vehicle to reverse, a neutral position, and a kickdown position for shifting the transmission from the range to the lower range;
- wherein the rocker is positioned in the forward position by pressing the rocker towards the forward position with a first force, the rocker is positioned in the reverse position by pressing the rocker towards the reverse position with the first force, the rocker is positioned in the neutral position by pressing the rocker towards the neutral position with the first force, and the rocker is positioned in the kickdown position by pressing the rocker towards the forward position with a second force that is greater than the first force.
A method for controlling a work vehicle having a transmission with at least a range and a lower range having more power, the method comprising:
- providing a kickdown shift control device having a shift switch for switching a travel direction of the work vehicle and for shifting the transmission, the shift switch having a rocker with a forward position for changing the travel direction of the work vehicle to forward, a reverse position for changing the travel direction of the work vehicle to reverse, a neutral position, and a kickdown position for shifting the transmission from the range to the lower range;
- positioning the rocker in the forward position by pressing the rocker towards the forward position with a first force;
- positioning the rocker in the reverse position by pressing the rocker towards the reverse position with the first force;
- positioning the rocker in the neutral position by pressing the rocker towards the neutral position with the first force;
- and
- positioning the rocker in the kickdown position by pressing the rocker towards at least one of the forward position and the reverse position with a second force that is greater than the first force.
