Grasscool SS5000 Timecutter 50 inch 115-5059-03 Mulching Mower Blades for Toro Time Cutter MX5050 MX5000 MX5075 Z5000 50'' Deck Zero Turn Replace 110-6837-03

What It Is

The Grasscool SS5000 Timecutter 50 inch 115-5059-03 is a set of three mulching mower blades designed specifically for Toro TimeCutter and Z5000 zero-turn mowers with a 50-inch deck. They replace OEM part 110-6837-03 and are intended to finely chop clippings for nutrient recycling, not for bagging or side discharge.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch deck (not 42", 54", or 60"). These blades fit:

• Toro TimeCutter MX5050, MX5000, MX5075
• Toro Z5000 (50" deck models)
• Any Toro zero-turn using OEM blade 110-6837-03

What to check:

• Measure your current blade length: OEM is 20.5 inches center hole to tip
• Center hole diameter: 1 inch (square or round? These use a 1" round hole with a 5-point star pattern)
• Blade thickness: typically 0.203 inches (check your deck clearance)
• Not compatible with 50" decks on other brands (e.g., Husqvarna, John Deere) unless they share the same blade pattern

Key Things to Know

• Quality: Grasscool blades are aftermarket, often made from heat-treated boron steel. They’re slightly lighter than OEM, which may reduce blade tip speed slightly but still cut cleanly.
• Installation: Easy DIY job—lift mower, remove center bolt (likely 15/16" or 5/8" socket), replace blades, torque to 45-55 ft-lbs. No special tools needed.
• Common gotcha: The blades are sold as a set of three (left, center, right)—but all three are identical, so orientation doesn’t matter. However, some users report needing to balance them after install (use a blade balancer).
• Mulching performance: Works best with dry grass; clogging can occur in wet or tall grass. Consider a high-lift blade for bagging if you switch often.

Should You Buy It

If you own a Toro TimeCutter or Z5000 with a 50" deck, need a budget-friendly mulching blade set, and don’t mind a slight trade-off in blade life vs. OEM (typically 20-30% shorter lifespan), this is a solid value at $35.88. It’s ideal for homeowners mulching regularly, but pros who cut daily may prefer OEM for durability.
