105-8777-03 Gator Mulching Blades for 60" Deck, Compatible with Toro 74245 74246TE 74251 74255 74942 Lawn Mower, Replaces 105-7718 105-7777 105-8777, 3 Pack

What It Is

This is a 3-pack of Gator mulching blades designed for 60-inch Toro commercial zero-turn mowers. They replace OEM part numbers 105-7718, 105-7777, and 105-8777, and are intended for mulching (chopping clippings fine) rather than bagging or side-discharge.

Fitment & Compatibility

• Deck size: Fits only 60-inch cutting decks. Measure your deck width before ordering.
• Toro models: Confirmed for 74245, 74246TE, 74251, 74255, 74942. Check your model number on the mower’s frame or under the seat.
• OEM vs aftermarket: These are aftermarket (not genuine Toro) but match OEM specs. They replace 105-7718, 105-7777, and 105-8777 directly.
• Measurement check: Blade length should be 20.5 inches, center hole 5/8 inch, and thickness 0.1875 inch (3/16"). Measure your current blade to confirm compatibility.

Key Things to Know

• Quality: Gator blades have a serrated edge for finer mulching but may wear faster than standard blades in sandy or rocky conditions.
• Installation difficulty: Moderate. You’ll need a socket wrench and torque wrench (70-90 ft-lbs). Always disconnect the spark plug first.
• Common gotcha: These blades are for mulching only—they reduce lift for bagging or side-discharge. If you switch between modes, you’ll need separate blade sets.
• Balance: After installation, check blade balance (on a balancer or nail) to avoid vibration and spindle wear.

Should You Buy It

Buy these if you own a Toro 60-inch commercial mower and want a cost-effective mulching upgrade (roughly 30% less than OEM). They’re ideal for frequent mulching in clean lawns, but skip them if you mostly bag or cut in heavy debris—standard blades will last longer.
