Keeping your riding mower‘s blades sharp is essential for a healthy lawn and a smooth mowing experience. Dull blades tear grass, leaving brown, ragged edges and potentially damaging your lawn. Changing blades is a fairly straightforward task, but it does involve jacking up the mower, which can seem daunting for some. This guide will walk you through the process of how to jack up a riding mower to change blades, making it a simple and safe endeavor.
Gather Your Tools and Supplies
Before you begin, ensure you have the necessary tools and supplies. You’ll need:
- A jack: Choose a jack with a capacity that exceeds the weight of your riding mower.
- Jack stands: Two jack stands are crucial for safety and stability.
- Socket wrench: Select a wrench that fits the bolt size securing your mower blades.
- New blades: Ensure you purchase the correct blades for your specific mower model.
- Gloves: Protect your hands from potential cuts and grime.
- Safety glasses: Shield your eyes from flying debris.
Find the Jacking Points
Your riding mower has designated jacking points, usually located near the axles. Consult your owner’s manual to identify these points; they are typically marked with a symbol or a specific shape. These points are reinforced for lifting and will prevent damage to your mower’s frame.
Engage the Parking Brake
Before lifting your mower, engage the parking brake to prevent it from rolling. This is a critical safety step that ensures your mower remains stationary during the entire process.
Position the Jack
Place the jack securely under the designated jacking point. Ensure the jack is level and stable before lifting the mower.
Lift the Mower Slowly and Safely
Lift the mower slowly and steadily using the jack. Once the mower is raised high enough to allow for blade removal, place the jack stands under the designated points.
Remove the Blades
With the mower securely supported by the jack stands, remove the blade bolts. You may need to use a wrench and a breaker bar to loosen the bolts if they are particularly tight. Once the bolts are removed, gently pull the blades off the spindle.
Install the New Blades
Position the new blades onto the spindle, ensuring they are properly aligned. Secure the blades with the bolts and tighten them securely, but avoid overtightening, as this could damage the spindle.
Lower the Mower
Once the new blades are installed, carefully lower the mower using the jack. Remove the jack stands after the mower is safely back on the ground.
Test Your Work
After lowering the mower, start the engine and run it for a short period. This will allow you to check for any rattling or unusual noises. If everything seems in order, you can enjoy your freshly sharpened blades.
Maintaining Your Mower Blades
For optimal performance and a healthy lawn, it’s recommended to sharpen or replace your mower blades every 25-30 hours of use. Regularly inspecting your blades will help you determine when they need attention.
Safety First: Essential Precautions
- Always wear safety glasses and gloves when working with your mower blades.
- Never work under a mower that is not securely supported by jack stands.
- Ensure the engine is off and the spark plug is disconnected before working on the blades.
- If you are unsure about any step, consult your owner’s manual or a qualified mechanic.
Final Thoughts: Taking Care of Your Mower
Learning how to jack up a riding mower to change blades is a valuable skill for any homeowner. By following these steps, you can ensure your mower is always ready to tackle your lawn with sharp, efficient blades. Remember to always prioritize safety and consult your owner’s manual for specific instructions related to your mower model.
