(2 Pack) Replacement High Lift Lawn Mower Blades for MTD/Cub Cadet/Troy-Bilt 942-04244 742-04244 742-04290 942-04244A 942-04290, Fits Cub Cadet LTX1046 LTX1045 46'' Deck Mower Review

Overview

If you own a Cub Cadet, MTD, or Troy-Bilt riding mower with a 46-inch deck, this two-pack of replacement high-lift blades is designed to restore your machine’s cutting performance. At $26.99, it’s a budget-friendly way to keep your lawn looking sharp without buying OEM blades every season. These blades are ideal for homeowners who want a simple, direct replacement that delivers better grass lift and mulching than standard blades.

Who Should Buy This

1. Owners of Cub Cadet LTX1046 or LTX1045 mowers – These are the most common models this blade fits, and if you’re running a 46-inch deck, this is your go-to replacement. No adapters or modifications needed.

2. Homeowners with 1–2 acre lawns – The high-lift design excels at pulling up grass for a cleaner cut, especially on thicker turf like fescue or bluegrass. If you mow weekly and want a manicured look, these blades deliver.

3. Budget-conscious DIYers – At $13.50 per blade, this two-pack is cheaper than buying single OEM blades from the dealer. If you sharpen your own blades and rotate them mid-season, this is a smart buy.

4. Mulching fans – The high-lift design chops clippings finer and distributes them evenly, reducing the need for bagging. If you prefer leaving clippings on the lawn for nutrients, these blades help prevent clumps.

Key Features Breakdown

High-Lift Design – The curved, raised edges create a strong vacuum that pulls grass upright before cutting. This is critical for preventing “scalping” on uneven ground and for picking up leaves in the fall. It’s not just about the cut—it’s about the overall lawn health.

Direct Fit for MTD/Cub Cadet/Troy-Bilt – These blades match OEM part numbers 942-04244, 742-04244, 742-04290, and more. The center hole and blade length are identical to factory parts, so installation is a 10-minute job with a socket wrench.

Durable Steel Construction – The blades are made from heat-treated carbon steel, which holds an edge longer than budget stamped blades. Expect 20–30 hours of mowing before they need sharpening, depending on your soil and grass type.

Two-Pack Value – You get two blades in the box, which is perfect for replacing both blades on your 46-inch deck at once. Many mowers (like the LTX1046) use two blades, so this is a complete set.

Universal Fit Across Multiple Brands – Beyond Cub Cadet, these blades fit MTD and Troy-Bilt models with the same deck. Double-check your deck’s part number, but this covers a huge range of popular mowers.

Pros

• Better grass lift than standard blades – The high-lift design really does pull up matted grass, especially in damp conditions. You’ll see a noticeable difference in cut quality.
• Direct fit, no modifications – Bolts right onto your spindle without grinding or shimming. If you can change a tire, you can install these.
• Affordable for a two-pack – At $26.99, you’re paying about half of what a dealer would charge for two OEM blades. Great value.
• Works well for mulching – The lift helps recirculate clippings for finer chopping. Your lawn won’t look like a hayfield after mowing.
• Durable edge retention – These blades stay sharp longer than the cheap stamped ones you find at big-box stores. You’ll sharpen less often.
• Compatible with popular models – Covers Cub Cadet, MTD, and Troy-Bilt 46-inch decks, so if you have a common mower, this fits.

Cons

• Not for bagging – The high-lift design actually reduces airflow into the bagging chute compared to dedicated bagging blades. If you bag clippings, you might get more clogs.
• Requires proper deck leveling – High-lift blades are more sensitive to an uneven deck. If your deck is out of level, you’ll see streaks or uneven cutting. Check your deck before installing.
• No included hardware – You’ll need to reuse your existing bolts and washers. Not a big deal, but worth noting if your bolts are rusted or stripped.
• May cause more wear on belts – The increased lift creates more resistance, which can stress your deck belt slightly more than standard blades. Not a dealbreaker, but if your belt is old, consider replacing it at the same time.

Bottom Line

These replacement high-lift blades are a solid, cost-effective upgrade for anyone with a Cub Cadet, MTD, or Troy-Bilt 46-inch deck. They deliver a cleaner cut with better grass lift, especially for mulching or mowing thicker lawns. The two-pack value is hard to beat, and installation is straightforward. If you’re looking for a direct replacement that improves cut quality without breaking the bank, this is your set. Just skip them if you primarily bag clippings—there are better options for that. For everyone else, these blades will keep your lawn looking sharp all season.

Frequently Asked Questions

Q: Will these fit my Cub Cadet LTX1046 with a 46-inch deck?
A: Yes, this two-pack is designed specifically for the LTX1046 and LTX1045 models. The blade length and center hole match exactly. Just make sure your mower uses two blades (most 46-inch decks do).

Q: Do I need to sharpen these before first use?
A: No, they come pre-sharpened and ready to install. You can put them on and mow immediately. They’ll need sharpening after about 20–30 hours of use, depending on conditions.

Q: Can I use these for bagging leaves in the fall?
A: They’ll work, but they’re not ideal. High-lift blades are better for mulching and side-discharge. For bagging, look for a dedicated bagging blade with a flatter profile that pushes clippings into the chute more efficiently.
