How to Measure a Lawn Mower Blade

Posted on: April 14th, 2017 by usmb No Comments



Knowing how to properly measure a lawn mower blade will make it much easier to find the proper replacement. There are three major measurements to consider: length, width, and center hole. Other important measurements to note are thickness and distance between outer holes. Also take note of the center hole type and measurement.


LENGTH: Length is measured diagonally from one tip of the blade to the opposite tip of the blade. It is important to measure the length correctly. Measuring from end to end will result in the wrong blade length. All length measurements must be made diagonally.


WIDTH: The width of the blade should be measured at the widest and flattest part of the blade – typically near the center of the blade. The width can be measured normally from edge to edge.


CENTER HOLE: The center hole measurement will depend on the type of hole being used. There are several different types of center holes: round, fiveCenter Hole Graphic-point star, six-point star, seven-point star, rounded rectangle, and H-pattern also known as bow tie.


Round center holes should be measured for inner diameter. 5-point star, 6-point star, and 7-point star center holes will not have a measurement but will be denoted by name. H-pattern or bow tie center holes will also not have a measurement. H-pattern center holes will accommodate several different spindle types including 5-point star, 6-point star, or triangle spindles.


Rounded rectangle center holes will typically have two measurements, inner length and inner height. Most lawn mower blades will have round center holes.


Some blades will have an extra set of holes set to either side of the center hole. These outer holes are measured two different ways — individual diameter and the space between the holes. Measure the outer hole inner diameter the same way as a center hole. The correct way to measure the distance between outer holes is from the center of one hole to the center of the other hole.

Toothed Lawn Mower Blades

Posted on: March 28th, 2017 by usmb 1 Comment

The toothed lawn mower blade is a versatile 3-in-1 blade designed for discharge, bagging, and mulching. Toothed blades, while not always true mulching blades, are better for mulching than USMB-CMB-276-3BP-000_05standard high-lift blades. The blade teeth do not have a cutting edge but are used to create extra lift, propelling grass clippings high into the mower deck.


The angle of the teeth is designed to force the grass clipping back toward the cutting edge. When the grass clippings fall back through the mower deck and the blades, they will be cut again before landing on the lawn.


Toothed lawn mower blades are the ideal 3-in-1 blade as they offer the best of all three intended purposes. The high-lift and powerful suction works well for bagging clippings as well as expelling clippings out the side discharge. The mulching capability of the blade will work in conjunction with the discharge or bagging function to ensure finely cut clippings.


Using a toothed blade solely for mulching purposes may not be ideal since some toothed blades do not have the extended cutting edge. For a lawn care professional looking to cover all the bases, toothed blades are the way to go.


USA Mower Blades manufactures toothed lawn mower blades for a variety of the most popular lawn mower models.

Standard Blades vs Mulching Blades

Posted on: March 28th, 2017 by usmb 2 Comments

Mulching_StraightThere are two basic types of lawn mower blades – standard blades and mulching blades. Telling them apart is easy when you know how the blades work and what to look for. Standard blades, sometimes referred to as 2-in-1 blades, are designed to cut grass and then either discharge or bag the clippings. Standard and high-lift blades are straight and aerodynamic as possible to create a powerful lift that will expel the grass clippings from under the deck.


Standard blades are the ideal choice when mulching the grass clippings may not be an option. Many professionals prefer to bag the clippings for a cleaner looking lawn. Bagging clippings will also remove leaves and debris from the lawn, leaving behind a well-manicured cut. Bagging is also a wise option for lawns that do not receive a frequent mowing. Over-grown grass can clog under the mower deck and leave unsightly clumps of grass on the freshly mowed lawn.


Mulching blades, also known as 3-in-1 blades, can be used to bag, discharge, or mulch grass clippings. Mulching blades feature more curves and an increased cutting edge. The curved surface and increased cutting edge allows the blade to cut the grass and bring it into the deck where it is cut several more times before falling back onto the lawn in much smaller pieces. The curved design of a mulching blade does not provide the same type of lift and discharge power as standard blades. Mulching blades are an excellent choice for use on lawns that receive a mowing every three to four days. Using mulching blades on overgrown grass can result in clogging under the deck and piles of grass on the cut lawn.


Mulching is also an environmentally friendly way to deal with grass clippings. Mulched grass clipping and leaves act as a natural fertilizer. Plants like grass and trees take up nutrients from the soil and store them in their leaves. Mulching this organic material will return the valuable nutrients back to the soil that the plants can use again.

Finding the Right Mower Blade

Posted on: January 20th, 2017 by usmb No Comments

Finding the right mower blade can be challenging. The problem with purchasing replacement lawn mower blades online is they all look the same. Not being able to pick up the new blade and compare it the old blade can be frustrating. That’s why USA Mower Blade is trying to take the guess work out of buying replacement blades. Need a new blade? Or three? Start here:


Original Equipment Manufacturer Number. The easiest way to find replacement lawn mower blades is with the OEM number. The OEM number is the numerical part number of the blade assigned by the manufacturer. In most cases, just typing this number with the manufacturer name into a search engine or online store will be enough to bring up some promising results. Don’t have the OEM number? Not to worry, it is easy to find. Check the manual that came with the mower.


Model Name and/or Number. Don’t have the OEM number or a manual? Manuals for most newer mowers can be found on the manufacturer’s website. Searching for the mower manufacturer and model number is an easy way to find the needed information.


Length and Center Hole. Without an OEM number, manufacturer name, or model number, it can be difficult, but not impossible, to find the right replacement lawn mower blade. There are two blade characteristics to look at: blade length and center hole design.


LAWN4The blade length should be measured diagonally from the opposite tip on each side. A blade that is too long will not fit under the deck while a blade that is too short will leave grass uncut. Finding the right blade length is very important.


The center hole is how the blade attaches to the spindle assembly under the mowing deck. There are several different types of center hole designs, including circle in various sizes, rounded rectangle, H-pattern, Y-pattern, and 5-point, 6-point, or 7-point star pattern. With the exact blade length and the correct center-hole pattern or size, it will be easy to identify the correct replacement lawn mower blade.
