Benefits of Sharpening Mower Blades
Using a bench grinder to sharpen your mower blades is an easy, quick and efficient way to keep your lawn in top shape. A sharp blade means cleaner cuts and less stress on the mower, which can lead to improved efficiency and extended motor life. The technique is also incredibly straightforward — all you need are the right size grinding wheel, a strong light source, two gloves and a few pieces of masking tape.
Sharpening mower blades increases the lifespan of both the blades and the lawn overall — leaving each blade dull for too long can sacrifice a lot of grass in its place. When blades are allowed to stay dull for too long, it damages grass by pulling it up instead of cutting it off cleanly. A sharpened blade ensures cleaner cuts that truly protect each individual blade of grass with fewer torn or broken stalks. That means healthier lawns overall that allow homeowners to save money they would have spent replacing problem areas over time.
In addition to preventing unnecessary damage, another major benefit of sharpening mower blades is that they reduce unwanted debris and clippings. When you use a sharpened blade mowing your lawn, there’s less flying debris with fewer clumps or clods left behind on the ground or stuck in your lawnmower bag or bed (or sticking up ominously out of the ground). This saves time on cleanup as well as reducing problems like soil compaction caused by stray clippings mixing with air pockets under the surface soil structure — something all gardeners should want when keeping their turf healthy!
Types of Bench Grinders
A bench grinder is a versatile tool suitable for sharpening mower blades, tools and other objects. Before buying a bench grinder, it is important to consider the different types on offer and which one is most suitable for your particular task. There are two main types of bench grinders – stationary and portable.
Stationary Bench Grinders: A stationary bench grinder consists of two grinding wheels – typically an 8-inch wheel on the left side and a 6-inch wheel on the right side. These two wheels are fixed in place and are driven by either an electric motor or a diesel engine at a constant speed of around 2,500 RPM (revolutions per minute). Stationary grinders typically come with adjustable rests that allow you to secure items you’re working on to either grinding wheel, making them ideal for precise work such as sharpening lawnmower blades or quickly creating mirror finishes in metal objects.
Portable Bench Grinders: Portable bench grinders are smaller than their stationary counterparts but they make up for this with their versatility as they can be taken from job to job site without having to be uprooted from one place. As such, these tools are popular with those who need fast sharpening solutions away from their workshop or garage. Portable grinders use either grinding wheels that have been specially designed for this purpose or heavy duty diamond grinding discs that have tougher abrasive materials embedded in them – both options having the potential to tackle tougher tasks more effectively than traditional abrasive discs used by stationary grinders. They also have adjustable rests which allow them to securely hold items you’re working on like stationary grinders do.

When shopping for a bench grinder for sharpening mower blades, there are several features to consider. In order to get the best results and longest life out of your grinder, it’s important to choose one that meets your specific needs. Here’s a list of features to look for when shopping for a bench grinder:
Size and Power: Generally speaking, larger grinders are better suited for heavier work and more demanding tasks, whereas smaller grinders are better suited for lighter jobs. For sharpening mower blades, you’re likely to want a size between 8-inches and 10-inches with an adequate amount of power (measured in Watts).
Wheel Size: A larger wheel will allow you to work faster because it covers more surface area. You’ll also want to look for wheels made from good quality materials like aluminum oxide or white aluminum oxide; these materials offer the best performance and won’t corrode over time from exposure to water or other elements.
Bearing Type: Most of the better bench grinders use ball bearings instead of bushings as this prevents wear from vibration and improves accuracy. Make sure the bearings are properly sealed so they stay clean and free from moisture damage longer.
Dust Collection System: If you don’t want metal dust all over your workshop, look for a model with an effective dust collection system like a vacuum or dust port that leads outside. This will keep cleanup quick and easy.
Safety Switch/Shields: Safety is always paramount when dealing with any power tool; therefore make sure that the grinder you select is equipped with basic safety switches/shields such as an off switch, spark guard cap, wheel guard, adjustable shield guards on all four sides of the wheel etc.
Safety Tips for Using the Best Slow Speed Bench Grinder for Sharpening
When operating a bench grinder for sharpening mower blades, it’s important to take safety precautions. A bench grinder is a powerful tool that generates sparks and debris and can cause eye, respiratory or hearing damage if not used properly. It’s important to wear the proper safety equipment, including safety glasses and ear plugs or muffs; long pants, shirt sleeves and closed-toe shoes should also be worn.
Before starting work on the mower blade, unplug the grinder and make sure to clear away any nearby objects from the work area. Make sure that the grinding wheel is firmly attached to the machine; loose pieces may interfere with operation or cause injury as you work. Inspect all pieces of your bench grinder before use; check for damage in the motor housing area, frayed power cords, cracked shields and worn wheels before proceeding.
In addition to ensuring that all pieces are securely connected and working properly, it’s also important to select the right type of grinding wheel for your needs. Check with your manufacturer or retailer when selecting a grinding wheel; they can provide advice on finding one that is designed specifically for sharpening blades safely and effectively.
Finally, whenever possible test-run any used equipment before beginning work on an item such as a mower blade so you have full assurance of proper performance in advance. Taking these measures will ensure your safety when operating a bench grinder for sharpening mower blades.
