Mower repair is safe once you remember to follow basic good working practices. Watch the video before attempting any repairs, most are just common sense.

However if you only remember one of them, remember this one:

When working on your mower engine, always remove the plug wire to prevent accidental starting.

Tools & Parts

To nail this procedure you may need the following tools, parts and supplies.


DeWalt Eye Protection

The DeWalt glasses are made from tough polycarbonate. They're lightweight, impact proof, offer UV protection and are vented to prevent fogging. For those of us that need glasses the DeWalt can handle RX inserts. Picture links to Amazon.com

3M Ear Defenders

Lawn mowers can produce over 100 db which is more than enough to damage your ears. I like the quality of the 3M products, I've been using them for years. This set of ear defenders has an NRR of 24 db (Noise Reduction Rating).

The set is Bluetooth connected, so no cables to mess about with, you can seamlessly connect to your phone, listen to music and take calls as the headset has a built in mic. Pretty cool! Picture links to Amazon.com


Mechanic Gloves

Constant vibration can damage the nerves in your hands, It's known as Hand Arm Vibration Syndrome (HAVS) and it's not repairable. Mowers as you know create a lot of vibration which is transmitted through your hands.

I wear Mechanix gloves in the workshop when using air tools, they're made with thermoplastic padding material that absorbs and dissipates vibration. Picture links to Amazon.com


3M Respirator

I love 3M products, they're great quality and I'm confident in there performance as I've been using them since forever. The silicone respirator is comfortable and durable. I use it when welding and cleaning old grass and dust from lawn mower decks and engines.

I wear glasses in the workshop and anybody that wears glasses and a respirator will know the value of the 3M downward facing vent. Fogged glasses drive me crazy!!! Picture links to Amazon.com


Ratchet Tool Set

Before we can do anything, we'll need tools. I've selected this set as I own some Craftsman tools and while I have worn some out, they did do a lot of work. So I expect this set will last the occasional user quite a long time.

This set carries both metric and standard sockets and that's important, because some mowers will have both type of fastener sizes. Set includes spark plug sockets. Picture links to Amazon.com


Gas & Oil Syphon

You'll find this tool really useful if you need to drain the gas tank, and you will if the gas is stale. The siphon will remove it without fuss or mess and it can be used for extracting the oil too. Picture links to Amazon.com

Gas Line Clamp

Some small engines will have a gas tap, which is really handy when removing the carburetor, stops gas flowing all over the shop. However most engines won't have one, these useful clamps simply squeeze the fuel line and prevent a spill while you perform surgery. Picture links to Amazon.com

Ignition Tester

This tool is used to check both the spark plug and the coil for spark. Sure you can check the spark without the tool, but it's not as good, the tool is designed to stress the whole ignition system. Picture links to Amazon.com

Impact Wrench

I love DeWalt, they're make quality tools. This heavy duty but lightweight 1/2 inch impact wrench makes short work of stubborn bolts like flywheel nuts and rusty blade fasteners. Upto 700 ft lbs of torque on tap, I keep one in the trunk of our family car, makes a flat almost enjoyable. Picture links to Amazon.com

Drill/Screw Gun

I use a Dewalt screw gun (also a drill) in the workshop to speed up the process of removing engine covers, carburetor bolts, Armature bolts etc. It's a brushless motor and as tough as nails, I driven over it a few times - still works great! Batteries are interchangeable and so if you have a Dewalt product already you won't need the battery. Picture links to Amazon.com

Torque Wrench

Teng 1/2 Torque wrench, fantastic tool I use it every day and mine is still going strong. A torque wrench is advised for tightening components such as flywheel nuts and blades. The torque spec of these components is very important. Picture links to Amazon.com

If you are considering buying a torque wrench, definitely check out my review of Teng torque wrench.


Blade holding tool

Very useful blade holding tool, used to hold the blade steady while the blade bolt is loosened and tightened. Picture links to Amazon.com
