PTO note
Use the John Deere S120’s 18.5 hp PTO rating when sizing implements; the 18.5 hp engine rating is not the number the implement actually receives.

Power-to-weight note
Using 736 lb operating weight and 18.5 hp engine power, the John Deere S120 comes out at roughly 39.8 lb per engine horsepower, meaning it is light for its power, so traction and ballast can become the limiting factor before engine power.
