Grasscool 42-inch Toro TimeCutter Mower Blades — Direct-Fit Replacement, Medium-Lift

Grasscool replacement blades for 42-inch Toro TimeCutter decks restore cutting power and fit Toro part numbers 106-2247-03 / 110-1857-03 / 110-6568-03 for a medium-lift, 42" mowing deck.

If your Toro TimeCutter or compatible Z-series zero-turn is leaving uneven strips, struggling through thick growth, or you need a reliable spare set, these Grasscool blades are designed as direct-fit replacements. Built to the exact diameter and center-hole pattern required by many Toro 42" decks, they deliver a medium-lift profile for balanced clippings and solid performance when tackling both regular lawns and heavier vegetation.

How do I confirm these blades fit my mower?

Before buying, verify the center spindle hole on your mower blades and the deck size. These replacements require a circular 5/8" center hole and are intended for a 42" deck; mismatched patterns will prevent correct installation.

• Measure center hole diameter: must be 5/8" (0.625 inch).
• Confirm deck size: compatible with 42-inch TimeCutter decks.
• Cross-check OEM numbers: 106-2247-03, 110-1857-03, 110-6568-03.
• Reference Toro models: SS4235, Z4235, Z4200, SS4260, SS4200 and labeled decks like 74360 series.

What are the blade dimensions and metal specs?

Each Grasscool blade matches the original geometry so your deck balance and cut quality stay consistent. The blades are made to thickness and length specifications that allow sharpening and repeated use while maintaining structural strength.

• Length: 21-5/8" (550 mm); Width: 2-1/4" (57 mm).
• Thickness: 5/32" (4 mm) for durability and reduced flex.
• Lift height (blade profile): 15/16" (24 mm) — medium lift for even discharge.
• Center hole shape: Circle (5/8") — confirm spindle pattern before purchase.

How do these blades perform on thick or overgrown grass?

Grasscool engineered these blades for tougher mowing conditions while still producing a clean finish on maintained lawns. The medium-lift design helps move clippings efficiently through the deck and supports mulching or side discharge depending on your deck setup.

• Designed to power through heavy growth and weeds without excessive bogging.
• Edges can be re-sharpened to restore a crisp cut for formal lawns.
• Painted cutting edges reduce rust during storage and handling.
• Tested for hardness, bend resistance, balance, and field performance.

What should I know about installation and maintenance?

Installation is straightforward if your spindle pattern matches; always follow safety steps and torque specs from your mower manufacturer. The blade paint protects the edges during shipping and initial installation but will wear with use, so sharpening is normal maintenance.

• Wear gloves when handling—painted edges protect hands but blades remain sharp.
• Check blade balance after mounting to avoid vibration and deck wear.
• Re-sharpen periodically for best grass health and fuel efficiency.
• Dispose of or recycle old blades responsibly; replace in matched sets if needed.

Who is this for? If you own a Toro TimeCutter or compatible 42" zero-turn with a circular 5/8" spindle and need a reliable, rebuildable blade that balances lift and cut quality, these Grasscool blades are a practical replacement. They suit homeowners and landscapers who want OEM-style fitment, the ability to sharpen blades for longer life, and a durable option for mowing both maintained lawns and heavier vegetation. Avoid purchasing if your mower uses a different center-hole pattern or a non-42" deck; check measurements first to ensure a correct fit.
