What It Is

A set of three 54-inch mower deck blades designed for residential and commercial zero-turn mowers, specifically for cutting grass on Exmark Quest E and S-Series and Toro TimeCutter, Titan, SS5425, MX5475, and SW5425 models. These replace OEM part numbers 115-9650-03, 115-2454-03, 115-4999, and 115-4999-03.

Fitment & Compatibility

Before buying, verify:

• Deck size: Only for 54-inch decks. Measure blade length end to end—must be 18 inches.
• Model check: Fits Exmark Quest E (S/N above 400,000,000) and S-Series; Toro TimeCutter SS4225, SS5425, MX5475, SW5425; Titan MX5400, MX5500, SW5400, SW5500.
• Center hole: 5/8-inch diameter with a 2-inch diameter triangle-shaped center hole (some models require a 5-point star—confirm yours).
• OEM cross-reference: Matches Toro/Exmark 115-9650-03, 115-2454-03, 115-4999, 115-4999-03. If your current blades have a different OEM number, measure length and center hole before purchase.
• Thickness: Typically 0.204 inches—check if your spindles accept this, as thicker blades may cause interference.

Key Things to Know

• Quality: Aftermarket blades—good for residential use; may dull faster than OEM on heavy commercial duty.
• Installation: Straightforward if you have a 15/16-inch wrench and a torque wrench (tighten to 70-80 ft-lbs). Lift deck safely with blocks, not a jack.
• Common gotcha: These blades are not universal—some Toro/Exmark decks use a 5-point star center hole; this set uses a triangle. If your spindles have a star, these won’t fit.
• Balance: May need balancing before install—unbalanced blades cause vibration and uneven cut.

Should You Buy It

Buy this if you own a compatible 54-inch Exmark Quest E/S-Series or Toro TimeCutter/Titan and want a budget-friendly replacement for residential mowing. Skip it for heavy commercial use or if your deck requires a 5-point star center hole—stick with OEM for durability and guaranteed fit.
