JSXDNWYJ High-Lift Mower Blades for Toro TimeCutter 42" Deck — 42in Replacement Set, High-Lift for Better Bagging

JSXDNWYJ 131-3939-03 high-lift mower blades are replacement 42-inch blades engineered to restore lift, clipping quality, and bagging performance on compatible Toro TimeCutter and Exmark Quest/Series decks.

These aftermarket high-lift blades are built to match the fit and basic dimensions of OEM 131-3939-03 / 106-22747-03 blades so you can reinstall quickly and get back to mowing with reliable clearance and suction. Cut dimensions measure 21-1/2" long, 2-1/4" wide, and 0.157" thick with a 5/8" center hole, making them suitable for a broad range of residential and commercial zero-turn mowers with 42" decks. The set is intended for users who need a direct-fit replacement for worn or damaged blades used for bagging, side-discharge, or intensive clipping tasks.

Which mowers will these blades fit?

These blades are designed to be compatible with many Toro TimeCutter models and select Exmark Quest and Series machines that use a 42-inch deck and the OEM 131-3939-03 specification. Check serial ranges for some Exmark models to ensure compatibility before ordering.

• Toro TimeCutter: SW 4200, SS 4200, SS 4225, SS 4250, MX 4200, MX 4250, SWX 4250 (42" decks)
• Exmark Quest/Series: QZE/QTE/QTS/QSS models listed in product specs with specific serial ranges
• OEM equivalence: Replaces Toro/Exmark part number 131-3939-03 / 106-22747-03

How do these blades affect cut quality and bagging?

High-lift blades create stronger upward airflow inside the deck, which helps lift grass for a cleaner cut and improves material evacuation to mulch systems or bags. Expect better suction for bagging and more consistent clipping discharge compared with low-lift designs.

• Enhanced deck airflow for improved clipping pickup
• Sharper, more uniform cuts when blades are balanced and sharpened
• Better bagging performance on machines configured to collect clippings

What are the physical specifications and installation notes?

The blades come in the exact size required to replace the OEM part: 21-1/2" length, 2-1/4" width, 0.157" thickness, and a 5/8" center mounting hole. Install them one at a time onto the spindle, torquing hardware to your manufacturer's specification and ensuring blade orientation and balance before operation.

• Blade length: 21.5"; width: 2.25"; thickness: 0.157"
• Center hole: 5/8" to match standard spindles
• Installation: tighten to mower OEM torque spec and check balance

How long will these replacement blades last and how should I maintain them?

Blade life depends on terrain, frequency of use, and contact with obstacles. Regular inspection, prompt sharpening, and replacing bent or fractured blades will extend deck performance and safety.

• Inspect for nicks, bends, or heavy wear after each use
• Sharpen blades evenly and maintain original cutting angle
• Replace if blade thickness is compromised or balance cannot be restored

Who is this for: These JSXDNWYJ high-lift blades are aimed at homeowners and professional landscapers who operate Toro TimeCutter or compatible Exmark machines with 42" decks and need OEM-form-fit replacements. They're suitable for anyone wanting improved bagging and lift compared with low-lift blades, as well as those restoring cutting performance after extended use or damage. Always confirm model and serial compatibility for Exmark units and follow your mower manufacturer's safety and installation guidance before use.
