• the plurality of forward gear shift stages includes:
• a low-speed gear shift stage with a largest gear ratio among the plurality of forward gear shift stages;
• and
• a predetermined gear shift stage with a gear ratio closest to a gear ratio of the reverse gear shift stage among the plurality of forward gear shift stages;
• the transmission includes:
• a predetermined gear shifting lever controlled by the operator to shift gear shift stages in the transmission;
• a lever arm to rock in a front-rear direction of the work vehicle by an operation of the predetermined gear shifting lever;
• and

• the lever protector assembly is operable to stop the lever arm from rocking forward beyond a predetermined position by contact with the lever arm;
• the lever arm includes a first lever arm and a second lever arm outside the first lever arm in a width direction of the work vehicle;
• the lever protector assembly includes:
• a first lever protector to stop the first lever arm from rocking forward beyond the predetermined position by contact with the first lever arm;
• and
• a second lever protector to stop the second lever arm from rocking forward beyond the predetermined position by contact with the second lever arm, the second lever protector being spaced apart from the first lever protector in the width direction;
• the first lever protector is a rod-shaped first member that extends upward from the step;
• and
• the second lever protector is a rod-shaped second member that extends upward from the step and is different from the first member.
