3PK Oregon 596-319 G5 Gator Blades for 60" Toro 105-7718, 105-7777, 105-8777

What It Is

This is a set of three Oregon G5 Gator mulching blades (596-319) designed for 60-inch zero-turn mowers, specifically replacing Toro OEM blades (105-7718, 105-7777, 105-8777). They excel at fine mulching in leaf-heavy or high-volume grass conditions, reducing clippings into small particles that decompose quickly.

Fitment & Compatibility

Check these before buying:

• Deck size: Only fits 60-inch cutting decks—not 52", 54", or 72".
• Model compatibility: Direct replacement for Toro TimeCutter, Titan, and Z Master models using OEM blades 105-7718 (center), 105-7777 (left), and 105-8777 (right). Confirm your mower’s blade part number matches one of these.
• Aftermarket fit: Oregon G5 is a premium aftermarket option; will not fit EGO or other battery mowers despite listing “Brand: EGO” (likely a listing error).
• Measurements: Each blade is 20.5" long, 2.5" wide, with a 5/8" center hole and a 3.2" blade offset. Measure your old blade if unsure.
• Hardware: Does not include bolts or washers—reuse original or buy new ones (Torco 1/2" fine thread).

Key Things to Know

• Mulching performance: G5’s “Gator” serrated edge cuts grass and leaves multiple times, producing finer clippings than standard lift blades. Best for mulching, not bagging or side-discharge.
• Installation: Moderate difficulty—requires removing deck or tilting mower. Use a torque wrench (45-55 ft-lbs). Avoid over-tightening; it can strip the spindle.
• Balance: Oregon blades come pre-balanced, but verify with a balancer after install. A wobbling blade causes vibration and poor cut.
• Durability: Oregon’s heat-treated steel holds an edge longer than many OEM blades, but hitting rocks or stumps will still chip them. Inspect after heavy use.

Should You Buy It

If you own a 60-inch Toro zero-turn and primarily mulch heavy grass or leaves, this is a top-tier upgrade over standard blades. The fine mulching action reduces clumping and bagging frequency, making it ideal for large lawns with frequent leaf cleanup. Avoid if you need bagging performance or have a different brand deck.
