UDC Parts 405380 46-inch Mower Blades (Medium Lift) 2-Pack for Husqvarna YTH22V46, Z246 & More
Product description
The essentials
If you maintain a 46-inch riding mower, blades are one of those parts you don’t really think about until performance starts to slip. The UDC Parts 405380 46-inch mower blades are built as a replacement for multiple OEM part numbers, and they’re aimed at restoring that cleaner, more even cut you expect from a deck this size.
On paper, this is the kind of purchase that makes sense when your current blades are getting dull, nicked, or just not cutting like they used to. It’s also a “buy with confidence” type of product if you’re good at matching model numbers—because the listing itself stresses confirming the complete model number for proper fit.
That said, it’s not magic. If your mower deck is damaged, bent, or something else in the cutting system is off, new blades can’t fully compensate. Blade replacement helps, but it depends quite a bit on overall deck condition.
What you get and what it replaces
This is a 2-pack of 46-inch mower blades identified with the part number 405380 (also listed alongside several compatible/replacement OEM numbers). The set is marketed as a replacement for specific Husqvarna, Craftsman, and other models mentioned in the description.
Important detail: compatibility is tied to the mower model and the deck size. The blades are identified as compatible with 46-inch mower decks, and the deck size appears in the provided specs.
You’ll also want to take the time to cross-check the complete model number in your mower manual or on the label before buying—because the listing repeatedly points out that doing so is the key to a proper fit.
Tech specs that matter in real mowing
These blades are specified for a 46-inch deck and include practical geometry details that influence installation and cutting setup. The listed dimensions and features include: - Length: 23" - Width: 2-3/4" - Center hole: 5-point star - Air Lift: 1-3/16" - Cutting edge length: 9-1/4" - Compatible deck size: 46"
One small nuance to keep in mind: the length is measured diagonally from one end to the other. That’s normal for mower blade listings, but it can be a point of confusion if you’re comparing with an older blade from your garage and measuring the “wrong” way.
Where it shines (and where it may fall short)
If your goal is to get back to more consistent mowing results, this pair is designed for exactly that: replacing blades on a 46-inch deck with a stated “Medium Lift” blade type.
Where it tends to make the most sense: - You’ve noticed uneven cutting or the grass looks like it’s being torn rather than cleanly cut. - Your current blades are dull or damaged and you’re planning a straightforward blade swap. - You want a 2-pack so both blades can be replaced together (often the cleaner approach when one blade is clearly worse).
Where it might not be the best match: - If your mower model doesn’t fully match the list in the description, you could run into fit issues—even if the deck size looks right. - If you’re expecting a major performance “upgrade,” blades alone usually won’t change how the mower handles heavy conditions unless the current blades are the limiting factor.
It’s also medium-lift by description, so if you specifically run for a high-lift discharge/collection goal, you may find this doesn’t align with your setup. The listing doesn’t claim maximum lift or a specialty mowing profile—so your expectations should stay realistic.
How to choose confidently before buying
This is the part that saves you time later. Before you click buy, confirm a few things:
- Your mower’s complete model number (not just brand or deck size).
- That your deck is actually a 46-inch deck.
- That your current blade center hole matches the listed 5-point star style.
- Whether your mower is listed among the compatible models in the description.
A quick practical check: if you’re removing blades this weekend, place the new blade next to your old one and visually confirm the mounting pattern and cutting edge orientation. It doesn’t have to be complicated—just enough to spot mismatches before installation.
Family comparison mindset: blades vs. “fixing the symptoms”
A lot of buyers see poor cut quality and assume the solution is an engine tune, new tires, or a deck adjustment. Sometimes that’s true, but often the real culprit is blade condition.
Replacing blades like these is usually the sensible path when: - Your cut looks ragged. - The mower doesn’t seem to disperse grass the way it used to. - You’re maintaining as part of regular upkeep.
But if your deck is bent, spindles are failing, or the mower deck height is wildly out of spec, new blades might only get you partway back.
Who this is for (and who should skip it)
It suits you if you own a compatible 46-inch riding mower from the models mentioned in the description and you’re trying to refresh blade performance with a 2-pack replacement. It’s also a good fit if you prefer replacing both blades at once for more even results.
You may want to skip it if you can’t confidently confirm the complete model number and deck compatibility. Blade swaps are straightforward, but “close enough” compatibility can still turn into wasted time.
When it makes sense?
- Buy it when your mower’s blade performance is clearly slipping and your model/deck match the listing details.
- Buy it when you want a 2-pack replacement approach so both blades match.
Don’t buy it if you’re missing model number details or if your deck isn’t a 46-inch setup.
Is it worth it?
The UDC Parts 405380 46-inch mower blades (2-pack) are worth considering if you’ve confirmed your mower model and deck size and you’re specifically replacing blades as routine maintenance. The listing provides dimensions and mounting details (including the 5-point star center hole), which is exactly the kind of information you want when you’re trying to avoid fit problems.
Where people sometimes get disappointed is when they assume blades will fix an underlying deck or spindle issue. If the deck geometry is off or something else in the cutting system is worn out, new blades won’t fully erase the problem. Still, for the typical “my cut quality dropped” scenario, this is the kind of practical replacement that can make your mower feel right again—without turning the job into a mystery.
