Which machines does the LG191 kit fit?

What parts are included and why they matter?

This kit consolidates the routine consumables most commonly changed during scheduled maintenance so you get everything in one purchase. Using the specified OEM parts helps maintain filtration, oil cleanliness, and reliable ignition that the engine was designed for.

• AM125424 oil filter — captures contaminants to protect engine wear surfaces.
• AM116304 fuel filter — keeps dirt and rust out of the carburetor or fuel injection.
• M92359 air element and M92359 pre-cleaner — improve air flow while blocking dust.
• M78543 spark plug (RC12YC) — ensures stable ignition and easier starts.
• TY22029 oil (2 quarts) — packaged for immediate use during service.

How do I install the kit components during routine service?

Basic installation is straightforward for most home mechanics with common hand tools and a small workspace. Always service the mower on level ground with the engine cool and the spark plug wire disconnected for safety.

• Replace the oil and oil filter after draining warm oil for better flow and sediment removal.
• Swap the fuel filter inline or in-tank depending on your model’s location, following flow direction marks.
• Remove and inspect the air box, replace the pre-cleaner first, then the main air element.
• Replace the spark plug, gap to the manufacturer spec, and reconnect after reinstalling components.

Who this is for: The LG191 kit is aimed at homeowners and groundskeepers who perform scheduled maintenance themselves and prefer OEM parts for fit and reliability. It’s also a convenient option for dealers and small shops that service the listed John Deere and compatible Scotts models and want a single part number to cover routine tune-ups. If you’re unsure about fitment for your mower, contact a John Deere dealer with your model and serial number before purchase to confirm compatibility.
