The Ultimate Buying Guide for Lawn Mower Grease
Keeping your lawn mower running smoothly is important. Good grease helps the moving parts work well. This guide will help you pick the right grease for your machine.
Key Features to Look For
1. Temperature Resistance
Lawn mowers work in hot sun. The grease must handle high heat. Look for grease rated for high operating temperatures. This stops the grease from melting or running off too quickly.
2. Water Resistance
You often mow when the grass is damp. Water can wash away regular grease. Choose a water-resistant or waterproof grease. This protects metal parts from rust and corrosion.
3. Adhesion (Stickiness)
The grease needs to stick to the metal parts. Good adhesion means the grease stays where you put it. It forms a long-lasting protective film.
4. Load Bearing Capacity
Mower parts handle heavy loads, especially the wheels and blade spindle. The grease must resist being squeezed out under pressure. This is often called EP (Extreme Pressure) rating.
Important Materials in Lawn Mower Grease
Thickeners
Grease is oil mixed with a thickener. Different thickeners change how the grease performs. Common thickeners include lithium, calcium, and polyurea.
- Lithium Complex: This is very popular. It works well in many temperatures and resists water. It’s a great all-around choice.
- Calcium Sulfonate: This offers excellent water resistance and rust protection.
Base Oils
The base oil is the lubricating part. Most lawn mower greases use petroleum-based oils. Synthetic oils offer better performance in extreme cold or heat but cost more.
Factors That Improve or Reduce Quality
Quality Improvers:
High-quality greases often contain additives. These additives fight wear and tear. Anti-wear additives create a stronger barrier between moving parts. Rust inhibitors stop metal from rusting.
Quality Reducers:
Using the wrong type of grease hurts performance. Mixing incompatible greases can cause them to separate and fail. Old or contaminated grease loses its protective qualities. Always check the manufacturer’s recommendation before switching types.
User Experience and Use Cases
You use grease in a few key spots on your mower.
Wheel Bearings and Axles:
These parts spin constantly. They need a tough, sticky grease that resists washing out. Good greasing here makes pushing or driving the mower easier.
Blade Spindle:
This is a high-speed, high-stress area. The grease here must handle heat and vibration well. Proper lubrication prevents the spindle from seizing up.
Control Cables and Linkages:
Greasing pivots and cables makes steering and throttle control smooth. A lighter, non-tacky grease sometimes works best here so movement isn’t stiff.
Tip: Always clean old grease off before applying new grease. Clean parts last longer.
10 Frequently Asked Questions (FAQ) About Lawn Mower Grease
Q: What is the most important feature of lawn mower grease?
A: Water resistance is very important. It keeps moisture out and prevents rust.
Q: Can I use car grease on my lawn mower?
A: Sometimes, but check your mower manual first. Car grease might not have the right temperature rating for mower spindles.
Q: How often should I grease my lawn mower?
A: Most people grease their mowers once per season, usually before spring use.
Q: What does “NLGI Grade 2” mean?
A: NLGI Grade refers to the grease thickness. Grade 2 is the standard, medium consistency for most general-purpose lubrication.
Q: Does synthetic grease last longer than regular grease?
A: Yes, synthetic grease often lasts longer and handles wider temperature swings better.
Q: What color should the grease be?
A: The color does not tell you the quality. Lithium grease is often blue or yellow, but color doesn’t matter as much as the material rating.
Q: Where can I find the correct grease type for my mower?
A: Check your owner’s manual. The manufacturer tells you the exact type and NLGI grade needed.
Q: Will too much grease hurt my mower?
A: Yes, too much grease can sometimes force seals out or attract dirt, creating a grinding paste.
Q: What is the difference between grease and oil for a mower?
A: Oil flows freely for splash lubrication, like in the engine. Grease stays put on fixed fittings and bearings.
Q: Should I grease the spark plug?
A: Absolutely not. Spark plugs need a tight, dry fit to work correctly.
