Chester, Yesterday’s Horse(1973)

It's about the faith of a fourteen-year-old boy in the family Belgian draft horse named Chester who was used at the local logging company. Chester was retired when modern equipment became available for the logging industry. His owner, Ben Kincaid, was injured in an accident and his son, Silver, tried to earn the money the family needed by entering Chester in the County pulling contest. Chester beat the other draft horses but lost to the modern tractor.
