Abstract
A work vehicle is provided. The work vehicle is capable of notifying an operator of a state close to overheating of a temperature of a cooling oil that cools a brake device before the temperature overheats. A controller () in a work vehicle () compares each detection value detected from a brake pressure sensor () and a vehicle speed sensor () to each threshold (V, P, R) predetermined corresponding to each sensor. The controller () outputs a warning command that a temperature of a cooling oil is likely to overheat to a notification device () when a state that at least one detection value is equal to or more than the threshold and when a state that at least one detection value is equal to or more than the threshold continues for a first duration (t) or more.
