Toro 20120P 30" Timemaster Blade Kit

What It Is

The Toro 20120P is a genuine OEM blade kit designed for Toro 30-inch Timemaster mowers. It includes two 15-inch blades and a center blade, optimized for the Timemaster’s three-blade cutting system.

Fitment & Compatibility

• Deck size: Only fits Toro 30-inch Timemaster models (e.g., 20333, 20334, 20339). Not for 22-inch, 42-inch, or other decks.
• Model check: Confirm your mower’s model number on the deck or under the seat. The 20120P replaces part numbers 131-6835, 131-6834, and 131-6833.
• OEM vs aftermarket: This is a genuine Toro kit—identical to factory blades. Aftermarket kits may vary in thickness, hole alignment, or material.
• Measurements: Each blade is 15 inches long, 1.75 inches wide, with a 5/8-inch center hole and 1/4-inch offset. Center blade is shorter (13 inches) with a different hole pattern.
• What to check: Measure your existing blades (length, width, hole size) and compare to the kit specs before buying.

Key Things to Know

• Quality: Made from hardened steel with a coated finish that resists rust better than most aftermarket options. Stays sharp longer than standard blades on thick grass.
• Installation: Moderate difficulty—requires removing the deck or tilting the mower. You’ll need a 15/16-inch socket and torque wrench (set to 70–80 ft-lbs). Center blade bolt is reverse-threaded (turn clockwise to loosen).
• Gotcha: The center blade bolt is notoriously tight. Use penetrating oil and a breaker bar. Never use impact drivers—risk of stripping.
• Frequency: Replace every 25–30 hours of use or when you see visible wear/dullness. If you hit a rock or stump, inspect immediately.

Should You Buy It

Yes, if you own a Toro 30-inch Timemaster and want hassle-free, guaranteed fit and OEM-level durability. It’s the right choice for anyone who values consistent cut quality and longer blade life over saving a few dollars on aftermarket alternatives.
