DIY Lawn Mower Repairs: How to Do This With the Best Parts

Do you have a problem with your lawn mower? If so, knowing how to fix something yourself saves money in the long run. So, use this information to save money on lawnmower repairs with the appropriate mower parts.

Like any other machine, lawnmowers require regular upkeep to function correctly. This includes sharpening the blades, replacing the oil after 50 hours of usage (or once a season), and cleaning the mower deck to avoid grass growth. However, even the most attentive lawnmower owners have to cope with broken components. So, discover the advantages of performing mower repair work on your own and which parts you may be able to replace with a bit of practice.

The process of replacing a mower part is only a simple web search away. You may get the specific replacement blade, cable, pull cord, or another item you require with just a few clicks and have it delivered right to your home. This way, the cost of parts will be decreased as well.

Repair shops often charge more for identical components than internet vendors since they pay for the technician’s time. And because you’ll have to drive your mower to and from the repair shop, non-DIY repairs also take longer. Furthermore, when it comes to many of these repairs, it’s possible to complete the mowing and then go on to other tasks.

Parts for Lawn Mowers

Given below are the most often worn-out mower parts.

Mower Blades

They are always dull, rusted, and twisted, making it challenging to keep them sharp. Fortunately, replacing them is a simple and affordable process. But before doing any repairs:

  1. Disconnect the spark plug wire.
  2. Flip your mower over and use a wrench to release the nut that secures the old blade to the mower’s frame.
  3. Replace the old blade with the new one and tighten the nut.

It is essential to choose a new blade with the correct length and hole spacing for your mower. Meanwhile, mower blades, often priced at $20 or less, may be found in various places, including online retailers and local hardware stores.


They are powered by a driving belt on certain self-propelled walk-behind mowers. As such, stretching or cracking might occur over time. So, it’s possible that a worn-out belt is to blame if your lawnmower isn’t driving itself perfectly. In that case, remove the belt cover, remove the old belt from the gearbox and drive pulleys by following your owner’s handbook instructions. And once you’ve put on the new belt, re-button everything.

Pull Cord Fraying and Breaking

Pull cords fray and break from repeated tugging. So a generic pull cord kit may be purchased and trimmed to the correct length, matching the previous one, or an exact replacement for your specific mower can be ordered. So to repair this, remove the starting assembly from your mower. And to get rid of the old cord, unwind it and cut it on both ends. Replace the starting assembly and handle with the new cable, knot it up at both ends, and rewind.

Spark Plug

It is possible that a defective spark plug is to blame if your mower is having difficulty starting. Meanwhile, you can acquire the spark plug you need online for a few dollars. As such, remove the old spark plug by disconnecting the spark plug wire and loosening it with a socket wrench. Ensure you don’t overtighten the new one by carefully threading it in and then tightening it with your wrench. Then, reconnect the spark plug wire, and you’ll be ready to go.

Replacement of Your Lawn Mower

Modern lawn mowers include many easily replaceable parts; however, certain repairs are so complicated that it is better to buy a new mower. Meanwhile, low oil levels or not changing the oil can cause significant engine harm. Besides, it’s unlikely that the ordinary homeowner can do significant engine repairs on their lawnmower, and such repairs are nearly always more expensive than purchasing a new mower. So to begin, you’ll need to go shopping.
