Replacement 110-6568-03 Mower Blades Fits Lawn Tractor 42'' Deck, Medium Lift Blade Compatible with Toro/ex Mark/Quest Series TimeCutter Z4200 Z4220 Z4235 SS 4235, 2 Pack

What It Is

This is a set of two replacement medium-lift mower blades designed for 42-inch cutting decks on select Toro, Ex Mark, and Quest series zero-turn mowers. They are intended for regular mulching and bagging tasks on residential or light commercial properties.

Fitment & Compatibility

Before buying, confirm your deck size is exactly 42 inches. These blades are a direct replacement for OEM part number 110-6568-03 and fit models including TimeCutter Z4200, Z4220, Z4235, and SS 4235. Also compatible with Ex Mark Quest series and some Toro LX/XL/XR lawn tractors with a 42-inch deck. Measure your existing blade length (should be ~20.5 inches) and center hole diameter (usually 1 inch). Check spindle orientation—some Toro decks use a star or oval center hole; this blade uses a standard 1-inch round hole with a 5-point star pattern. If your blade has a different hole shape, it won’t fit.

Key Things to Know

• Installation difficulty: Easy if you have a socket set and jack stands. Lift the deck, remove the center bolt, swap blades, and torque to 60-80 ft-lbs. Wear gloves—blades can be sharp.
• Medium lift vs. high lift: These blades provide moderate airflow for bagging and mulching but won’t throw clippings as far as high-lift blades. Best for flat, dry lawns.
• Common gotcha: The 110-6568-03 part is sometimes superseded by 110-6568-04. If you have a newer Toro deck, check the old blade for a stamped number to confirm compatibility.
• Quality: Aftermarket blades at this price point are typically heat-treated steel but may dull faster than genuine Toro blades. Expect 2-3 seasons of regular use before replacement.

Should You Buy It

If you own a Toro TimeCutter or Ex Mark Quest with a 42-inch deck and need a budget-friendly 2-pack for regular residential mowing, this is a solid choice. However, if you have a different brand or a deck with an unusual spindle pattern, skip it. For heavy commercial use, consider OEM blades for longer life.
