How to find your model number

Check your model number before you buy a replacement for the GY21098. On a riding mower or lawn tractor the model and serial label is usually under the seat, on the frame beside the seat, or near the battery. Deck parts may also need the deck size, which is often on a decal on top of the deck.

Spring maintenance

Spin each blade by hand (engine off, spark plug wire removed) before the first cut. Grinding, wobble or play in a spindle means it needs replacing.
