Lawnmower Blades

About Lawnmower Blades

Maintaining a healthy, well-manicured lawn starts with sharp, reliable lawnmower blades that deliver clean cuts every time. MyToolShed.co.uk stocks an extensive range of replacement lawnmower blades suitable for all major brands including Flymo, Bosch, Black & Decker, Qualcast, Einhell, and DeWalt. Whether you're a professional groundskeeper maintaining multiple properties or a homeowner who takes pride in their garden, having the correct replacement blade ensures your mower operates at peak efficiency and protects your lawn from damage.

Our selection encompasses both metal and plastic lawnmower blades designed for various cutting widths, from compact 10-inch blades for hover mowers to robust 420mm blades for larger rotary models. Metal blades offer exceptional durability and can be resharpened multiple times, making them ideal for tackling tougher grass conditions and uneven terrain. Plastic blades provide a safer, lighter alternative particularly suited to hover mowers and models used around flower beds and garden edges. We stock genuine manufacturer replacement blades as well as high-quality compatible alternatives from trusted brands like ALM, ensuring you'll find the perfect match for your specific mower model.

Choosing The Right Lawnmower Blades

Identify Your Mower Model: Confirm your exact mower make and model number, typically found on a label underneath the deck or in the owner's manual. This ensures you select a blade with the correct cutting width, centre hole diameter, and fixing specifications.

Metal vs Plastic Blades: Metal blades suit rotary mowers and tougher cutting conditions, offering longevity and the ability to be resharpened multiple times. Plastic blades are safer for hover mowers, quieter in operation, and cause less damage if they strike hidden objects, though they require more frequent replacement.

Match Cutting Width Precisely: Replacement blades must match your mower's cutting width exactly. Common sizes available at MyToolShed.co.uk include 320mm, 340mm, 350mm, and 420mm. An incorrectly sized blade won't fit safely or deliver proper cutting performance.

Consider Grass Conditions: For long, thick, or damp grass, opt for robust metal blades. For fine, regularly maintained lawns, standard replacement blades will suffice. Consider mulching blades if you prefer to leave clippings on the lawn rather than collecting them.

Plan for Seasonal Replacement: Most domestic users should replace blades at least once per season, whilst professional users may need monthly replacements during peak cutting periods. Keep a spare blade on hand to avoid downtime.

Safety Information

Always Disconnect Power: Before replacing or inspecting blades, disconnect the spark plug lead on petrol mowers or remove the battery/unplug electric models. Never work on blades whilst the power source is connected.

Wear Protective Equipment: Heavy-duty work gloves are essential when handling sharp blades. Safety glasses protect against flying debris when removing corroded fixings.

Secure Fixings Properly: Ensure all fixings are tightened to the manufacturer's specified torque. A loose blade can detach during operation, causing serious injury or property damage.

Check Blade Balance: An unbalanced blade creates dangerous vibration that can damage motor bearings. Always check balance after sharpening or when fitting new blades.

Frequently Asked Questions

How often should I replace my lawnmower blade?

For domestic users, replace your blade at least once per season (approximately 25 hours of mowing). Professional users may need monthly replacements during peak season. Signs that replacement is needed include ragged grass cuts, excessive vibration, visible damage, or if the blade can no longer be effectively sharpened.

Can I sharpen my lawnmower blade instead of replacing it?

Yes, metal blades can typically be sharpened 3-5 times before replacement is necessary. However, blades that are badly nicked, cracked, bent, or worn very thin should be replaced rather than sharpened. Plastic blades cannot be sharpened and must be replaced when dull.

Will a replacement blade from ALM fit my branded mower?

ALM manufactures high-quality compatible replacement blades for most major mower brands. Each ALM blade clearly states which models it fits. Always check the compatibility information and compare cutting width, centre hole diameter, and blade dimensions with your original blade to ensure proper fitment.
