Buying Guide

Apart from listing our top-recommended commercial lawn mower blade sharpeners, we also provide you with this comprehensive guide. You can find all the factors to consider when purchasing an ideal blade sharpener. Read on!

1. Compatibility

The most important thing to consider when purchasing a commercial lawn mower blade sharpener is whether it is compatible with the mower blades. It is worth noting that different mowers have different sized mower blades. For instance, 5 inches or 6 inches are some of the most common. Besides, the sharpening angle is also crucial. With options such as 40-degree grinders, go for a lawnmower blade sharpener that is fully compatible with your mower.

2. Spinning Speed

If you are considering purchasing an electric powered blade sharpener, you should check on your prospective commercial lawn mower blade sharpener’s spinning speed. Like with any other gardening power tools, the “rounds per minute” of the sharpener counts when determining your ideal choice. A higher RPM leads to higher efficiency and consequently sharpens the blades in a shorter period. Some of the most common RPM include 1500 RPM and 1750 RPM.

3. Power Type

There are two types of commercial lawn mower blade sharpeners available. Firstly, there is the electric-powered lawn mower blade sharpener that uses an electric motor. Secondly, there are manual lawn mower blade sharpeners that require you to use your hand effort to grind the blades. Both sharpeners come in handy with keeping your mower blades sharp and functional at all times.

Manual blade sharpeners are time-consuming, yet they have affordable prices. On the other hand, electrically powered blade sharpeners are more efficient and quicker. With both blades serving the same purpose, you can choose any of the two depending on your preference.

4. Motor Power

The powered blade sharpener comes with an electric motor that spins the grinding wheel. If you opt to buy the electric-powered commercial lawn mower blade sharpener, you must consider its motor power. Besides, most motor powers come as ¼ HP or ½ HP. In the same vein, a ½ HP motor has a higher power rating and results in advanced performance. Besides, a blade sharpener with a high-power rating can sharpen various blades in a short period.

5. Material

The durability of a lawnmower blade sharpener counts while determining the ideal option to purchase. Most importantly, if you are buying the mower blade sharpener for a commercial lawn, that means that you have to use it often. Besides, using it to sharpen various mower blades causes it to wear out over time. As a result, you should get your fingers right when deciding on your lawnmower blade sharpener’s material. Furthermore, those that have warranties are more durable. If you don’t want to waste time replacing the grinding wheel every time it wears out, go for grinding wheels made of strong materials like carbide.

6. Price

Although it is a fact that the higher the price, the better the product, you should be cautious on the price to quality ratio; nonetheless, always do thorough research on the cost of the commercial lawn mower blade sharpeners before you can make a purchase. This prevents you from being tricked into paying excessively high for a product.
