106-2247-03 Meduim Lift Blades for 42" Mower Deck Compatible with Toro TimeCutter Z420 Z4200 Z4202 ZS4200 ZS4202 Z530 Lawn Mower, Replaces 106-6583-03, 106-8744-03, 110-6568-03, 2 Pack

What It Is

This is a 2-pack of medium-lift replacement blades for 42-inch Toro TimeCutter zero-turn mowers. The medium lift design balances cutting performance with engine load, ideal for regular residential mowing on flat to moderately uneven terrain—not for heavy mulching or bagging.

Fitment & Compatibility

Check these before buying:

• Deck size: Only for 42-inch decks. Do not use on 44-, 50-, or 60-inch decks.
• Model fit: Confirmed compatible with Toro TimeCutter Z420, Z4200, Z4202, ZS4200, ZS4202, and Z530. Check your model number on the mower’s frame or under the seat.
• OEM vs aftermarket: This is a direct replacement for Toro OEM part numbers 106-6583-03, 106-8744-03, and 110-6568-03. Aftermarket blades may vary in thickness or steel quality—verify that the center hole and overall length match your originals.
• Measurements: Blade length is approximately 21.5 inches with a 1-inch center hole and 7-gauge thickness. Measure your old blade to confirm.

Key Things to Know

• Installation difficulty: Easy for DIYers. You’ll need a socket wrench or torque wrench to remove/install the blade bolt (usually 5/8-inch). Always disconnect the spark plug first.
• Medium lift vs high lift: Medium lift reduces engine bogging on thick grass but won’t throw clippings as far. If you need better bagging or tall-grass performance, consider high-lift blades instead.
• Balance check: After installing, spin the blade by hand to ensure it’s not bent. An unbalanced blade causes vibration, poor cut, and bearing wear.
• Sharpness: New blades are not pre-sharpened. You’ll need to sharpen them before first use for best results. Resharpen every 25 hours or after hitting debris.

Should You Buy It

If you own a 42-inch Toro TimeCutter and do standard residential mowing with occasional light mulching, this is a solid, affordable replacement. It won’t handle heavy bagging or very tall grass as well as high-lift blades, but for most users the medium lift offers a good balance of cut quality and engine strain. Check your model number and deck size carefully before buying.
