What Customers Are Saying

The John Deere S100 riding lawn mower is generally well-received as a reliable and capable machine for smaller to medium-sized yards. Customers praise its ease of use, smooth ride, and tight turning radius. The mower provides a clean, even cut and has sufficient power to handle most residential lawns. Features like the hydrostatic transmission, forward and reverse pedals, and deck wash system are appreciated. However, some customers have experienced issues with the belt, battery, or transmission, and a few found the ride to be rougher than expected on uneven terrain.
