115-9650-03 115-2454-03, 54 Inch Lawn Mower Blade, Fit for Toro 54 Inch Timecutter ZX5400 ZX5420 ZX5450 MX5400 MX5480 Deck Lawn Mower, Replace for 115-4999 115-4999-03 Mower Blade, 5 Year Warranty

What It Is

This is a 54-inch lawn mower blade set designed to replace OEM blades on Toro TimeCutter and MX series zero-turn mowers with 54-inch decks. It handles standard residential cutting and mulching for medium-to-large lawns.

Fitment & Compatibility

Before buying, confirm your mower has a 54-inch cutting deck—this blade only fits that size. Compatible models include Toro TimeCutter ZX5400, ZX5420, ZX5450, MX5400, and MX5480. It replaces OEM part numbers 115-4999 and 115-4999-03. Measure your existing blade length (edge to edge) and center hole diameter—this set matches OEM specs at 54 inches overall length with a 1-inch center hole. Aftermarket, not genuine Toro, so check that your deck accepts non-OEM blades without alignment issues.

Key Things to Know

• Quality: 4.6 stars from 173 reviews suggests durable steel and reliable cutting. The 5-year warranty is a strong confidence booster for an aftermarket part.
• Installation: Easy bolt-on replacement if you have a socket wrench and jack or block to lift the mower safely. No special tools needed.
• Common gotcha: Ensure you order the correct number of blades—these typically come as a set of 3 (one per spindle). Verify your deck uses three blades, not two.
• Sharpening: Pre-sharpened out of the box, but you’ll need to re-sharpen after 10–15 hours of use for best cut quality.

Should You Buy It

If you own a compatible Toro 54-inch zero-turn and want a reliable, budget-friendly alternative to OEM blades with a long warranty, this set is a solid choice. Avoid if you require genuine Toro parts or have a non-listed model.
