The John Deere D100 was introduced in 2011 as part of the 100 series lawn tractors, replacing earlier models in the John Deere lineup. Designed for residential use, it offered a balance of affordability and performance for homeowners with small to medium-sized lawns. The D100 typically featured a Briggs & Stratton single-cylinder engine, ranging from 17 to 17.5 horsepower, with a displacement around 500cc. Power was delivered through an automatic transmission, providing ease of use for operators. It was most commonly equipped with a 42-inch mower deck, ideal for navigating around obstacles in typical residential yards.
