106-0626 Mower Blades Fit 52 Inch Toro TimeCutter, 27-0990 Toothed Mulching Blade Compatible with Toro Z Master Groundsmaster, Replace for 108-1127, 56-2390, 92-7961, 44-5480, 3 Pack

What It Is

This is a set of three toothed mulching blades (OEM part 106-0626) designed for 52-inch Toro TimeCutter and Z Master zero-turn mowers. They replace OEM numbers 108-1127, 56-2390, 92-7961, and 44-5480, and are intended for fine mulching (not bagging or side-discharge).

Fitment & Compatibility

• Deck size: Only for 52-inch cutting decks. Measure your deck width to confirm—52" is the blade tip-to-tip length when installed.
• Models: Fits Toro TimeCutter (e.g., 75750, 75751, 75752, 75753) and Z Master (e.g., 74940, 74941, 74942, 74943) with 52" decks. Also fits Groundsmaster 4000/4500/4700 series with 52" decks.
• OEM vs aftermarket: These are genuine Toro parts—identical to the original blades on your mower. No fitment guesswork.
• Measurements: Blade length is 16.25 inches (center hole to tip). Center hole diameter is 1 inch. Check your spindle size—this uses a standard 5/8-inch hex arbor.
• What to check: Verify your mower deck model number (stamped on the deck or frame). If you have a 50" or 54" deck, these won’t fit.

Key Things to Know

• Mulching only: These are toothed mulching blades—they chop clippings finer than standard blades. Not ideal for bagging or side-discharge. If you switch, expect more clippings left on the lawn.
• Installation: Easy swap if you have a socket wrench and a torque wrench (tighten to 70-90 ft-lbs). Sharp edges—wear gloves.
• Common gotcha: The toothed design can be louder than flat blades and may leave a rougher cut if the grass is wet or tall. Keep blades sharp for best results.
• 3-pack value: You get three blades—enough for a full replacement on a 52" deck (typically 3-blade setup). No need to buy singles.

Should You Buy It

Buy this if you own a 52-inch Toro TimeCutter or Z Master and want genuine OEM mulching blades that fit perfectly and deliver fine clippings. It’s a solid choice for homeowners who prefer mulching over bagging and want a quick, no-guess replacement. But if you need bagging or side-discharge performance, look for standard lift blades instead.
