38 Inch Deck Mower Blades Fit for Cub Cadet LT-2138 2146 1515 1525 2130 2135 2146 Lawn Mower Replaces OEM 759-3829 742P3032 (Mulching) 2 Pack

What It Is

This 2-pack of 38-inch mulching blades is designed to replace OEM parts 759-3829 and 742P3032 on specific Cub Cadet models with a 38-inch cutting deck. They lift and recut grass clippings into fine particles to return nutrients to the lawn.

Fitment & Compatibility

Before buying, confirm your mower has a 38-inch deck — not 42 or 46 inches. These blades fit Cub Cadet LT-2138, 2146, 1515, 1525, 2130, and 2135 models. They also replace OEM part numbers 759-3829 and 742P3032. Measure your existing blade’s length (38 inches center-to-center of mounting holes) and center hole diameter (usually 1 inch). If your deck is 38 inches but the blade length differs, they won’t fit. Not for non-Cub Cadet brands or different deck sizes.

Key Things to Know

• Mulching vs. bagging: These are mulching blades — curved with more surface area. They won’t lift clippings well into a bagger. Use standard lift blades for bagging.
• Installation: Medium difficulty. You’ll need a socket wrench and a blade removal tool or block of wood to prevent spinning. Torque blade bolts to 70-80 ft-lbs — overtightening can strip the spindle.
• Quality check: 5.0 stars from only 2 reviews, so data is thin. However, they match OEM specs and should last a season with normal use on 1-2 acres.
• Balance: Always balance new blades before installing. Unbalanced blades cause vibration and damage spindles.

Should You Buy It

If you have one of the listed Cub Cadet models with a 38-inch deck and want to switch to mulching (or replace worn mulching blades), this is a solid, affordable direct-fit option. For bagging or side-discharge, choose standard lift blades instead.
