Brand new for the spring of 2024, Lawn Crack has introduced flat and low-lift lawn mower blades that are sharp on both sides and compatible with most commercial lawn mowers with deck sizes ranging from 32-inch to 61-inch.
2 blades in 1? Yes! Once you notice the cutting edge begin to dull as you mow, simply flip the blade over and keep cutting with a fresh cutting edge. The shape of flat and low-lift mower blades allow for all 4 sides to be sharpened. These blades have cutting edges on both sides!
These blades are made from hardened steel and have a 5/8" center hole diameter which is the most common center hole size for commercial lawn mower blades. Blades with 15/16" center holes are available for Exmark and Toro mower that accept the blade spline too.
Fitment - How to find the right blade for your mower?
Ask us if you need assistance determing which blade to use with your mower. You need to match your OEM blade's length and center hole diameter to ensure our blades are compatible. We've also listed OEM part numbers that each of these blades replaces to make it more clear.
We're here to help if needed. Please email us your mower's make, model, model number and size width for assistance at admin@iGoProLawnSupply.com.
Low-Lift Mower Blade Specs
Low-lift blades are most commonly used when cutting Southern, warm-season grasses. These blades are sharp on all four sides (S4S) and made from hardened steel to keep the cutting edge sharp longer and make them less likely to chip, bend or break. Low-lift blades are great for sand, but the flat blades in the chart below perform even better in sandy soil conditions.

High Lift Mower Blades
Yes. We also have hardened steel high-lift lawn mower blades! Currently we have 3 blade lengths using our 'Wing-Tip' extreme high-lift blade design all with 5/8" center hole diameters. The current lengths for high lift blades are 16-1/4", 18" and 20-1/2" to fit most commercial walk-behind, stand-on and zero turn mowers with a deck size of 32", 36", 48", 52" and 60".

The Best Value For Quality Lawn Mower Blades
We made our blades to offer a better value for similar to higher quality blades when compared to Stens Silver Streak blades, Rotary's Copperhead blades, and Fisher Barton's Marbain Steel XHT blades.
Our blades are most similar to the XHT blades because they are also made from hardened steel. We are a dealer for Stens, Rotary, and A&I Products and sell 1,000's of their blades each year. When we hold our blade up to any of these blades the precision in the craftsmanship is noticably better in our blades.
We'd like to get you a set so you can put them to the test.
Lawn Crack's S4S Blades
We named our low-lift and flat blades S4S (Sharpend 4 Sides) becuase they are sharpened on all 4 sides. Previously there was only a handful of blade specs available for blades that were sharpened on all four sides and they were often sold out.
We hope these blades are a gamechanger for lawn mower companies that mow hardy, Southern grasses and in sand soil conditions by allowing them to save time and money getting a fresh cutting edge on their mowers. Simply flip the blade at lunch and you have a brand new cutting edge for the second half of your day.
