The invention belongs to the technical field of tractors, and relates to a backrest structure and a tractor. The backrest structure comprises a backrest vertical plate, a backrest assembly and two guide plates. The two guide plates are vertically fixed to the backrest vertical plate in parallel, and guide grooves are formed in the guide plates. The backrest assembly comprises a backrest body, a supporting column and a guide shaft. The backrest body is fixedly connected to one end of the supporting column. The guide shaft is mounted on the supporting column, one end of the guide shaft is inserted into the guide groove of one of the guide plates in a sliding manner, and the other end of the guide shaft is inserted into the guide groove of the other guide plate in a sliding mode. The backrestbody is switched between a vertical state for leaning and a horizontal state for sitting or treading through sliding fit of the guide shaft and the guide grooves. The backrest body of the backrest structure can be used for three purposes so as to meet the requirements of different working environments.
