Tips for Proper Greasing
- Use correct grease: Multi-purpose NLGI #2 grease works for most fittings.
- Clean fittings first: Remove dirt and debris to ensure grease flows properly.
- Grease safely: Engine off, parking brake engaged, mower on a level surface.
- Avoid over-greasing: Apply until light seepage appears; excess grease can attract dirt or damage seals.
- Follow your manual: Always check the specific service manual for your model to confirm all grease points.
