YAMAKATO 21171-0743 Ignition Coil for Kawasaki John Deere X300

In this review the focus is on the YAMAKATO 21171-0743 ignition coil kit and who will benefit from it most. The bottom line: this is a practical OEM-quality replacement for Kawasaki V-twin engines and for lawn tractors such as the John Deere X300 when fitted with part 21171-0743, and it stands out for reliable starting and close fit to the original part. The kit arrives with two coils, two spark plugs and mounting bands, and in testing it produced quick, consistent starts and required only minor trimming in tight clearance applications.

Key Features

• OEM compatibility: Built to match Kawasaki part numbers 21171-0743, 21171-0711 and related variants so it fits engines specified for those numbers.
• Complete kit: Includes two ignition coils, two spark plugs and four bands so installers have what they need for a pair of cylinders without hunting parts separately.
• Designed for V-twin engines: Compatible with the FR, FX and FS Kawasaki series used in John Deere X300, Cub Cadet LTX1050 and Toro ZTR models, making it suitable for common mower V-twin applications.
• OEM-standard manufacturing: Produced by a leading coil supplier to meet original equipment expectations and designed to last as long as the original part.
• Resistor spark plug included: The kit supplies F5RTC type plugs with a resistor to mirror the original ignition system and reduce interference.

Who It's For

This kit is best for owners and independent mechanics working on Kawasaki-powered lawn tractors and zero turn mowers that specify the 21171-0743 coil, including John Deere X300 series (when 0743 is the required coil), Cub Cadet LTX1050 and Toro ZTR models. It suits people who want a direct replacement that closely matches OEM fit and function.

People who should look elsewhere include anyone whose engine requires the 21171-7034 coil type, since 21171-0743 cannot replace that variant, and those who need coils for small single-cylinder engines or models not listed among the compatible Kawasaki FR/FX series.
