How to Sharpen Push Reel Lawn Mower Blades
Sharpening the blades of your push reel lawn mower is essential for keeping your lawn healthy and ensuring a clean cut every time. Dull blades can tear grass instead of cutting it smoothly, which can lead to a brown, ragged lawn. Learning how to sharpen push reel mower blades at home is simple and saves you money on professional service.
Understanding the Parts of a Push Reel Mower
Before sharpening, it’s important to understand the main components that need attention. The cutting reel, bed knife, and the blade itself play crucial roles in mowing performance. The cutting reel is the rotating part with multiple blades, while the bed knife provides a flat surface that the reel blades cut against.
Tools Needed for Sharpening
Gathering the right tools makes the sharpening process easier and safer. Here is a list of essential items:
- Wrench or screwdriver to remove blades
- Sharpening stone or file
- Wire brush or stiff-bristled brush
- Protective gloves and eye protection
- Cloth for cleaning
- Lubricant spray (optional)
Preparing the Mower for Sharpening
Start by removing the mower from any power sources and placing it on a flat, stable surface. Use the wrench or screwdriver to carefully detach the reel or individual blades. Wearing protective gloves can help prevent injuries during handling.
Cleaning the blades and reel with a wire brush removes dirt, rust, and grass residues. This step ensures that sharpening is effective and helps prevent damage to the blades during the process.
How to Remove the Blades Safely
Loosen the blade bolts with the appropriate tool, turning them counterclockwise. Hold the blade firmly while removing the bolts to prevent slipping. Carefully set aside the blades in a safe area to continue sharpening.
If your mower has multiple blades, repeat the process for each one, making sure not to lose any hardware. Remember that some reel mowers have a fixed blade, so check your model before attempting removal.
Sharpening the Reel Blades
Using a Flat File
A flat file is a straightforward tool for sharpening reel blades. Hold the blade steady and move the file along the cutting edge with consistent pressure. Maintain the original angle of the blade, which is usually between 20 and 30 degrees.
Sharpen each blade by filing from the outside toward the center, ensuring a smooth, sharp edge. Regularly check the sharpness by feeling the edge carefully, being cautious not to cut yourself.
Using a Sharpening Stone or Grinder
A sharpening stone or a grinder can remove more material quickly and create a sharper edge. Use a fine-grit stone or a medium-grit grinder to avoid removing too much metal. Keep the blades at the same angle as when filing.
Work slowly and evenly, moving along the blade’s edge. It’s important to cool the blades with water if using a grinder to prevent overheating, which can weaken the metal.
Sharpening the Bed Knife
The bed knife provides the flat surface against which the reel blades cut. Use a flat file or a sharpening stone to make the bed knife flat and smooth. Be careful to remove any burrs or rough spots that could affect the cut quality.
Align the bed knife and reel blades carefully during reassembly to ensure a clean, even cut across the entire reel.
Reassembling the Mower
Once all blades are sharpened, clean them thoroughly and apply a light coat of lubricant or oil if desired. Reattach the blades to the mower, tightening bolts securely but without over-tightening, which can damage the blades.
Ensure the reel spins freely and the blades are aligned correctly. Spin the reel by hand to check for any wobbling or uneven cutting action. Make adjustments if necessary before testing the mower on grass.
Additional Tips for Maintaining Sharp Blades
- Regularly inspect your blades for dullness or damage, ideally every 10 to 15 hours of mowing.
- After each mowing session, wipe down blades to remove grass and debris that can cause rust and dullness.
- Store the mower in a dry place to prevent rust and corrosion.
- Sharpen blades at least once a season or more often if you mow frequently or on rough terrain.
Signs Your Push Reel Mower Blades Need Sharpening
- Grass appears torn or ragged instead of cleanly cut.
- Clippings are uneven or distributed poorly across the lawn.
- The mower requires more effort to push through the grass.
- The reel does not spin smoothly or wobbles during operation.
Professional vs. DIY Sharpening
While sharpening blades at home is manageable with proper tools and care, professional sharpening services are available if you prefer not to do it yourself. Professionals can sharpen blades more precisely and handle complex issues like bent blades or severe rust.
Deciding between DIY and professional sharpening depends on your comfort level, tools available, and the condition of your blades. Regular maintenance at home can extend the life of your blades and improve your lawn’s health.
