Signs your mower blades need sharpening

A simple sign is uneven grass. If you have been faithful to your schedule and the grass still has fault lines, it's time to check your blades. Here are other things to look out for:

Multiple rounds

Usually, it can take one to two rounds to cut grass. But if you find yourself going round and round with your lawn mower, its blades have become dull.

Just like knives, overuse subjects lawn mower blades to friction. When this happens, bring your mower to a sharpening specialist. They will have it up and running in no time. 

More effort

While this often applies to manually operated mowers, automatic mowers can have this problem, too. Because of dull blades, the chore of mowing becomes more strenuous. Mowing your lawn is manual labour. But if you find yourself working harder than usual, check your machine. Consult a lawn mower repair specialist if the blades are sharp but other parts need maintenance.

Torn grass

Dull blades produce torn grass, like nicks on the skin during a shaving session. Ideally, lawn mowers should have sharp blades to slice grass. Lawnmowing aims to cut off the tops and not the roots. If you leave the blades as is, you might find several bald spots on your lawn. When that happens, you must call lawn maintenance experts to help you. 

Dented blades

This goes beyond shape or style. Even if you deal with custom-designed blades, they usually come in a uniform shape or pattern. But if you see odd dents in the blades, they must be repaired or replaced because they can cause uneven cuts and uproot grass.

A stalling mower

This can be due to a motor issue. But if your machine is new, the odds of that are slim. Stalling due to dull blades is possible, especially since the mower compensates for the reduced work.

Can you request specific methods for mower blade sharpening?

It's best to consult a specialist when your mower blades need sharpening because they have the tools and expertise to simplify the process. Their sharpening method depends on the blade type. Ultimately, you have three options:

Bench grinder

The primary function of a bench grinder is to sharpen objects. It runs your lawn mower's blades through a metal wheel. It can also grind and shape tools. 

Hand file

This is a saw with an extensive blade used to cut and sharpen objects. It can remove rust buildup.


Angle grinder

This is a handheld tool with a whirring, spinning motor tip used for grinding, sanding, and sharpening.

Things to do before booking a Tasker for mower blade sharpening

Now that you know the cost of lawn mower blade sharpening, peruse this checklist before hiring a professional service:

  1. Double-check your warranty. Like most appliances, your lawn mower has a warranty. If you're lucky to still fall within that period, congratulations. But if your mower’s past its due, you need to pay for necessary repairs. Depending on your specialist's recommendation, you might have to replace your entire machine.
  2. Find the nearest professional. Doing this can spare you from delivery fees, especially if your Tasker comes from a distant place.
  3. Identify the parts needing repairs. Is it the motor or blades? Perhaps it's the handle. Do this so that your Tasker can bring the necessary tools. It also spares you from panicking because of the lack of equipment.

Experts recommend sharpening the blades 20 to 25 hours after use. Do this so that they stay sharp. Moreover, clean your mower deck twice every mowing season.

Yes, it's possible. The process is simpler but less effective in the long run.

Experts share that cooking oil or grease can increase work efficiency by half. The oil prevents grass from sticking to the blades, so you'll have an easier time cleaning or sharpening them.
