A bulldozer (1) is provided with a right first oil passage (101R), a right second oil passage (102R), and a right third oil passage (103R). A right first oil passage (101R) guides a part of the lubricating oil discharged from the hydraulic pump (81) to a right steering brake (50R). The right second oil passage (102R) guides a part of the lubricating oil discharged from the hydraulic pump (81) to the right planetary gear mechanism (30R). A right third oil passage (103R) guides at least a portion of the lubricating oil that has passed through the right planetary gear mechanism (30R) to a right steering brake (50R). At least a portion of the right planetary gear mechanism (30R) is disposed further inward than the right steering brake (50R) in the radial direction perpendicular to the axial center of the input shaft (26).
推土机(1)具备右第一油路(101R)、右第二油路(102R)以及右第三油路(103R)。右第一油路(101R)将从液压泵(81)排出的润滑油的一部分引导到右转向制动器(50R)。右第二油路(102R)将从液压泵(81)排出的润滑油的一部分引导到右行星齿轮机构(30R)。右第三油路(103R)将通过了右行星齿轮机构(30R)的润滑油的至少一部分引导到右转向制动器(50R)。右行星齿轮机构(30R)的至少一部分在与输入轴(26)的轴心垂直的径向上配置于比右转向制动器(50R)靠内侧。
