John Deere X300 Riding Mower Parts
The John Deere X300 is a popular lawn tractor known for its reliability and performance. Manufactured from 2006 to 2017, it features a Kawasaki engine ranging from 17-18.5 HP and was available with either a 42- or 48-inch mower deck. The X300's smooth hydrostatic transmission and durable build quality made it a favorite among homeowners.
The John Deere X300 was introduced in 2006 as part of the Select Series, designed to offer premium features and performance for residential users. This model replaced the Sabre and Scotts models sold at big box retailers. The X300 came standard with a Kawasaki engine, known for its smooth operation and longevity. Engine options included the Kawasaki FH491V, a 17 HP twin-cylinder in early models, and later the Kawasaki FS600V, ranging to 18.5 HP. It features a hydrostatic transmission, providing effortless speed control and maneuverability. Available deck widths included 42 inches and 48 inches. Key features included a comfortable high-back seat, easy-to-use controls, and a durable frame. The X300 is well-suited for homeowners with medium to large-sized lawns who demand a dependable and comfortable mowing experience. Unlike the entry-level D100 series or the LA series, the X300 offered a more powerful engine and a heavier-duty transmission for enhanced performance and durability. Compared to the X500 series, the X300 is lighter duty and features a smaller mowing deck. It is positioned as a premium residential lawn tractor, not quite a garden tractor, but much more capable than a box store model.

Maintenance Tips
- Belt Inspection: Regularly inspect deck and drive belts for cracks, wear, or fraying. Replace belts every 200-300 hours of use, or sooner if damage is evident.
- Blade Sharpening: Sharpen mower blades at least twice a season, or more frequently if you mow in sandy or abrasive conditions. Dull blades tear the grass instead of cutting it cleanly.
- Filter Changes: Change the engine oil and filter every 50 hours of operation or at least once a year. Replace the air filter annually, or more often in dusty conditions.

While there were no major redesigns during its production run (2006-2017), engine options changed to meet emissions standards.
