This category covers replacement blades and spare parts for garden tools and machinery, for owners who want a mower or trimmer to keep cutting cleanly instead of replacing the whole machine. Brands in our range include Airseekers, Roborock and BLACK+DECKER, so it suits both robotic and conventional garden equipment.
How to choose spare parts and blades for garden machines
Match the exact model. Blades and parts are made for specific machines, so check the model name and number on your mower or trimmer before ordering. A part that looks similar can differ in mounting holes, length or thickness, and a poor fit is a safety risk as well as a nuisance.
Know the machine type. Robotic mowers use small, light blades that are changed in sets, while conventional rotary and hedge cutting machines use larger blades that bolt on. Check which type of blade your machine takes before comparing products.
Check what is in the pack. Some blades are sold singly and others in sets, often with new screws or fixings. Robotic mower blades wear faster and are usually changed all at once, so a full set is more practical than a single piece.
Choose the right material. Steel blades are the usual choice for cutting grass and hold an edge well. Thin blades on robotic machines are designed to be replaced rather than sharpened. Heavier blades on larger machines can often be sharpened a few times before they need replacing.
Buy for the surface you cut. Regular grass, thick weeds and woody growth each wear a blade differently. If your garden has stones, roots or uneven edges, expect to replace blades more often and keep a spare set at hand.

Frequently asked questions about garden spare parts and blades
How often should I replace mower blades?
Replace them when the cut turns ragged, the grass tips look torn or brown, or the edge is visibly chipped or bent. For a robotic mower that works most days, blades are commonly changed every few weeks to a few months, depending on the lawn. Always follow the interval given in the manual for your model.
How do I know which blade fits my garden machine?
Find the model number on the machine's rating label or in the manual, then match it to the compatibility details of the part. Blade shape, length and mounting hole spacing must correspond to your machine. If the information is unclear, measure the old blade and compare it before ordering.
Can I sharpen blades instead of replacing them?
Sharpening is practical for heavy, thick blades on conventional machines, as long as the blade stays balanced and undamaged. Thin blades on robotic mowers are designed to be swapped, and sharpening them is rarely worthwhile. A bent, cracked or badly nicked blade should always be replaced.
Is it safe to change blades myself?
Yes, if you switch the machine off and isolate it from power first. Remove the battery or unplug the unit, wear thick gloves, and tighten the fixings exactly as the manual describes. On a robotic mower, also make sure it cannot start while you work on it.
