Abstract: A work vehicle user cabin is disclosed, comprising a floor and a series of structural pillars including first and second A-pillars, B-pillars, and C-pillars extending upward from the floor. A front window is positioned between the A-pillars, while a front side window is located between the first A-pillar and the first B-pillar. Additionally, a rear side window is situated between the first B-pillar and the first C-pillar. The rear side window features a straight top edge and a distinctive V-shaped bottom edge, with the V-shaped bottom edge formed by forward and rearward straight bottom edge portions joined at an obtuse angle that opens toward the interior of the cabin, enhancing the cabin's structural design and visibility.
