Abstract: A hose support structure includes a first round bar and a second round bar provided on a mounting surface of a first plate and extending in a first direction. A first restraint and a second restraint face the mounting surface in a second direction and are provided between the first round bar and the second round bar in a third direction. The first restraint extends from a first proximal end toward a first distal end in a fourth direction, and the second restraint extends in a fifth direction opposite to the fourth direction from a second proximal end connected to the first proximal end. A third restraint is provided opposite to the second restraint with respect to the first restraint in the first direction. At least a part of the second restraint is separated from the mounting surface by a second distance shorter than the first distance in the second direction.

Abstract: A work vehicle includes a cover having a center cover portion, a first side cover portion, and a second side cover portion. The center cover portion includes a punching metal and has a substantially rectangular shape. A first side and a second side of the rectangular shape face each other in a width direction, and a third side and a fourth side of the rectangular shape face each other in a front-rear direction. The first side cover includes a punching metal, has a substantially rectangular shape, is connected to the center cover portion at the first side, and is inclined downward in the height direction relative to the center cover portion. The second side cover includes a punching metal, has a substantially rectangular shape, is connected to the center cover portion at the second side, and is inclined downward in the height direction relative to the center cover portion.

Abstract: A work vehicle includes a first hydraulic pump that supplies hydraulic oil to a first hydraulic motor so as to drive a first travel device forward when hydraulic pressure applied to a first port is higher than hydraulic pressure applied to a second port, and a second hydraulic pump to drive a second travel device forward when hydraulic pressure applied to a third port is higher than hydraulic pressure applied to a fourth port. A first pilot oil passage, a second pilot oil passage, a third pilot oil passage, and a fourth pilot oil passage connect the operation device to first, second, third, and fourth ports, respectively. A first bypass oil passage connects the first pilot oil passage and the fourth pilot oil passage. A second bypass oil passage connects the second pilot oil passage and the third pilot oil passage. A first throttle is provided in the first bypass oil passage. A second throttle is provided in the second bypass oil passage.
