Grasscool mulching blades for Toro TimeCutter 50" deck — 17.5" direct-fit replacement, medium-lift mulching

Grasscool SS5000 Timecutter 50-inch mulching blades are direct-fit replacement blades designed to restore cutting performance on compatible Toro TimeCutter and Z-series 50" decks.

If your Toro mower is leaving uneven clippings, tugging under load, or you simply want to switch to mulching performance, these Grasscool blades are made to match OEM dimensions and mounting pattern for a simple swap. They are manufactured to the same critical measurements — length, width, thickness, center-hole shape and lift profile — so you can replace worn or damaged blades without altering your deck.

How do these blades improve mulching and lawn appearance?

The Grasscool mulching profile and medium-lift design finely chops clippings so they re-enter the turf and break down faster. That reduces visible clumping and returns nutrients to the soil while creating a cleaner finish.

• Medium lift (7/8" air lift) promotes circulation in the deck for better mulching.
• Optimized cutting edge geometry for finer clippings and even discharge.
• Proper length (17-1/2" / 445mm) keeps blade tip paths aligned with a 50" deck.

What are the exact specifications I should check before buying?

Measure your old blade and inspect the center hole shape to ensure a match. The Grasscool replacements mirror typical OEM dimensions so installation is straightforward when measurements align.

• Blade length: 17-1/2" (445 mm).
• Blade width: 2-1/4" (57 mm); thickness: 13/64" (5 mm).
• Mounting hole: circular center hole; lift type: medium lift.
• Compatible deck size: 50" — confirm your mower deck is 50" before purchase.

How should I handle and install these replacement blades safely?

Always wear gloves and disconnect the spark plug before replacing blades. The paint applied to the blades is a protective coating for storage and handling and does not need to be removed prior to first use.

• Disconnect battery or spark plug before blade removal and installation.
• Tighten mounting bolts to your mower manufacturer’s torque specification.
• Paint protects against rust and handling marks; it wears off during initial use.

Who is this for: These Grasscool SS5000 mulching blades are for Toro owners who need a reliable, dimensionally accurate replacement for a 50" TimeCutter or Z-series deck. Ideal for homeowners and small-property landscapers seeking improved clipping distribution and a neater cut without modifying the mower.
