What It Is

This is a 3-pack of replacement lawn mower blades designed for 54" cutting decks on select Craftsman, Cub Cadet, MTD, and Troy-Bilt zero-turn and lawn tractors. The set is intended for medium-to-large residential properties where regular mowing and occasional mulching or bagging are needed.

Fitment & Compatibility

Before purchasing, verify three things:

1. Deck size: Only fits 54" decks. Do not use on 46", 50", or 60" decks.
2. Model numbers: Compatible with Craftsman T3200, TT440, Z5800; Cub Cadet XT1-GT54, XT1-ST54, ZT1-54, ZT1-54P, ZT2-54, ZTS2-54; MTD ZT1-54; Troy-Bilt Super Bronco 54K XP, Z54 XP. If your model isn’t listed, measure your existing blade length (should be ~20.5"), center hole diameter (typically 1"), and spindle pattern (usually a 5-point star or oval).
3. OEM vs aftermarket: These are aftermarket blades, not genuine Cub Cadet/MTD parts. They may differ slightly in thickness or balance. If your mower is under warranty, check that aftermarket blades won’t void it.

Key Things to Know

• Quality: Made from heat-treated steel, but some users report they wear faster than OEM blades on sandy or rocky soil. Sharpen more frequently for best cut.
• Installation difficulty: Easy if you have a socket set and a block of wood to jam the blade. Torque to 70–90 ft-lbs. Use thread locker if your spindles are aluminum.
• Common gotchas: Blades may arrive with a protective coating that needs to be wiped off before first use. Also, the center hole is slightly tighter than OEM on some spindles – file it gently if needed. Do not mix these with other blade styles on the same deck.
• Performance: Designed for mulching but work fine for side-discharge or bagging if you use the correct deck baffles. Expect a slightly rougher cut than OEM on thick, wet grass.

Should You Buy It

Buy this 3-pack if you have a 54" deck tractor listed in the fitment guide and want a budget-friendly replacement set for regular residential use. It’s a solid value for the price, especially if you don’t mind sharpening more often. Skip it if you need OEM durability for heavy commercial use or if your model isn’t listed and you can’t verify blade measurements.
