8TEN LawnRAZOR Blade Set for Cub Cadet GT2186 GT2544 MTD 44" Deck 759-3939 742-3036 (Medium Lift) 3 Pack

What It Is

This is a set of three medium-lift replacement blades designed for 44-inch cutting decks on Cub Cadet and MTD lawn tractors. They are intended for regular grass cutting, not mulching or bagging, and suit homeowners with medium-sized lawns.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 44 inches wide (measured blade tip to blade tip). This set fits Cub Cadet models GT2186, GT2544, and other MTD-built tractors using OEM part numbers 759-3939 or 742-3036. Measure your existing blade’s length (should be about 18 inches), center hole diameter (commonly 7/8 inch or 1 inch), and the distance from the center hole to the outer mounting hole. Check your mower’s manual or current blade for these numbers—mismatched hole patterns won’t bolt on. This is a direct aftermarket replacement for those OEM numbers, not universal for all 44-inch decks.

Key Things to Know

• Medium lift only: These blades provide moderate airflow for clean cuts on standard grass but won’t handle heavy mulching or thick wet grass well—expect clumping.
• Installation: Straightforward if you have a socket wrench and a block of wood to jam the blade. Torque the center bolt to 40-50 ft-lbs; overtightening can strip the spindle.
• Balance check: Aftermarket blades sometimes need balancing. Use a simple blade balancer or nail in the wall—if one side drops, file the heavy end slightly. Unbalanced blades vibrate and damage spindles.
• Sharpness out of box: These come sharp but may need a quick hone if you notice tearing. They’re made from hardened steel and hold an edge reasonably well for a season.

Should You Buy It

If you own a Cub Cadet GT2186 or GT2544 with a 44-inch deck and need a direct, affordable replacement for standard cutting, this set is a solid choice. It’s not for mulching or heavy-duty use, but for basic lawn care at about $13 per blade, it’s a good value with strong reviews. Skip it if your deck size or hole pattern differs, or if you need a high-lift or mulching blade.
