What It Is

This is a set of 60-inch deck mulching blades designed to replace OEM parts on Toro, Bad Boy, Exmark, and select Titan lawn tractors and zero-turn mowers. They are intended for grass clipping mulching—fine cutting and recirculation to return nutrients to the lawn—rather than bagging or side discharge.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 60 inches (measured cutting swath, not deck shell width). These blades cross-reference with OEM numbers 105-7777, 115-9649, 105-7718, 038-6060-00, and 038-6050-00. They fit Toro TimeCutter SS, Z Master, Grand Stand, and Titan HD 1500 models, plus Bad Boy 60" decks and Exmark Lazer Z units that use those OEM blades. Measure your existing blade length (should be ~20.5 inches), center hole diameter (must be 1 inch or 7/8 inch—check yours), and thickness (typically 0.203–0.250 inch). Verify the spindle pattern matches (usually 5-point star or 6-point). If your deck uses a different blade offset or sail height, these may not fit or perform correctly.

Key Things to Know

• Quality: Aftermarket blades—check for balanced construction and consistent heat treatment. Some users report they are slightly heavier than OEM, which can affect spindle wear over time.
• Installation difficulty: Moderate—requires lifting or tilting the deck, removing blade bolts (likely 5/8 or 3/4 inch), and torquing to spec (typically 70–90 ft-lbs). Use a blade removal tool and wear gloves.
• Common gotcha: Mulching blades have a higher lift and more aggressive cut than standard blades. They can bog down the engine in tall, wet grass—keep mowing speed moderate.
• Fit check: Always test-fit one blade before torquing all. Slight variations in center hole diameter or offset can cause vibration or poor cutting.

Should You Buy It

Buy these if you have a 60-inch Toro, Bad Boy, Exmark, or compatible Titan deck and want an affordable mulching alternative to OEM blades. They are best for homeowners or light commercial use who prioritize fine mulching over bagging. Avoid if you need exact OEM fitment for heavy commercial duty or if your deck uses non-standard spindle patterns.
