Abstract: A work vehicle includes a vehicle body, a guiding pipe, a first heating section, and a second heating section. The vehicle body has a partition wall that partitions a space in an inner section into a first region and a second region. The guiding pipe is configured to guide a reducing agent. The guiding pipe has a first pipe section and a second pipe section. The first pipe section is positioned inside the first region. The second pipe section is positioned in the second region. The first heating section heats the first pipe section. The second heating section heats the second pipe section and adjusts the temperature independently from the first heating section.

Abstract: A filter remover removes a cylindrical filter element housed in a housing through an opening provided in the housing. The filter remover includes: an attachment portion provided with a screw to be screwed onto the opening; an insert portion that includes a base end integrated with the attachment portion and a tip end in a form of a free end, that is elastically deformable in a radial direction orthogonal to an axial direction of the filter element in conjunction with a movement in the axial direction caused when the attachment portion is screwed, and that is inserted through the opening into a center hole provided in the filter element as the attachment portion is screwed; and an engaging portion that is provided at the tip end and that is engaged with the filter element after the attachment portion is moved for a predetermined amount when the attachment portion is screwed.
