How To Sharpen Toro Mower Blades

A Toro mower behaves consistently to keep your mower in optimal working order, which is crucial to maintaining a beautiful, healthy lawn. The most important aspect of mower care is sharpening the blades. Dull blades tear grass rather than slice cleanly, which leaves an unforgiving blade edge that allows disease to move in and does not leave your lawn looking even.

In this guide, we will give you a step-by-step demonstration of sharpening Toro mower blades so you can enjoy a smooth mowing experience and yard!

Why Is Sharpening Important

When a blade is sharp, it slices cleanly through the grass and allows the grass to heal even faster and remain greener than if the blade is dull. You don't necessarily see it right away, but a dull blade means your lawn is more susceptible to stress and/or discoloration than if you sharpened the blades. Generally speaking, that is true for all mowers.

Sharpening Toro Blade

Toro mowers make mowing as easy and efficient as possible, so settling for any less than caring for your mower will lead to untimely delays. You should sharpen your mower blades at least once or twice a season to maintain velocity!

Essential Tools

First things first, make sure you have the necessary tools before starting:

  1. A socket wrench (to remove the blade)
  2. A workbench vice or clamp (to hold the blade)
  3. A metal file or grinder (for sharpening)
  4. Gloves and goggles for safety
  5. A balancing tool (to assure it is balanced)

Having the right tools not only makes for a simple job, but it also protects you.

How to Sharpen the Blades step by step.

Step Instructions
Step 1: Disconnect the Spark Plug Begin with safety by always disconnecting the spark plug wire before servicing the Toro mower and exposing sharp metal parts. This step creates a barrier of protection in case the spark plug should become reengaged.
Step 2: Start by Removing the Blade Tilt the mower over onto the side opposite the carburetor and air filter, so that those items do not leak onto the mower support surface. Use an appropriately sized socket wrench to loosen the bolt that secures the blade. Use chalk or a permanent marker to indicate the bottom side of the blade position for ease of reinstallation of the blade with the same orientation.
Step 3: Clean Off the Blade Before sharpening the blade, you should thoroughly clean off any residual grass, dirt, and debris. Use a stiff wire brush to scrape off the residuals. You want only a clean blade to sharpen, so that you can clearly see the blade's cutting edge.
Step 4: Sharpen the Blade If available, use a bench vice of some type to secure the blade, or alternatively, you can clamp it into some other stationary device. The blade can be sharpened with a file or grinder – when using a file or grinder, sharpen the edge in a single motion within a consistent angle (about 30 degrees) and remove only enough metal necessary to re-establish sharpness (do not over-grind the blade).
Step 5: Check Balance After the blade has been sharpened, you can place it on a balancing device or suspend it by the center hole on a nail. If one side hangs lower than the other, you need to remove more material from that side. An unbalanced blade can do permanent damage to your Toro mower’s engine and bearings.
Step 6: Reattach the Blade After your blade is balanced, reattach the blade to the mower in the same established direction you noted earlier. Torque the bolt down, but don’t overdo it to avoid stripping the threads. Replace the spark plug wire, and you are ready for mowing.

How Often Should Toro Mower Blades Be Sharpened?

For regular homeowners, it is often sufficient to sharpen blades once or twice a season - or even monthly, if you mow frequently. However, you should sharpen more than twice during the season if you mow frequently, have thick grass to cut, or routinely mow over debris, like limbs, branches, or rocks, you should sharpen your blades more frequently.
