The invention relates to the technical field of transmissions, in particular to a transmission for a bulldozer. The transmission comprises an input shaft and an output shaft and further comprises five planet rows, namely, the first planet row, the second planet row, the third planet row, the fourth planet row and the fifth planet row. The input shaft is connected with the first planet row and the second planet row. The output shaft is connected with the third planet row, the fourth planet row and the fifth planet row. Each planet row is correspondingly provided with a clutch. The clutches are used for being connected with sun gears and gear rings of the corresponding planet rows. Different gears can be switched by controlling the different clutches on the input shaft and the output shaft to be engaged at the same time. According to the transmission for the bulldozer, the structure of replacing planet rows and rotary clutches with the full planet rows is adopted, the structure is simple, the part manufacturing difficulty is lowered, and the transmission efficiency of the transmission is improved.
