8TEN LawnRAZOR Blade Set for Toro Time Cutter Z 50 Inch Deck 110-6837-03 (High Lift) 3 Pack

What It Is

This is a 3-pack of high-lift replacement blades for Toro TimeCutter Z zero-turn mowers with a 50-inch fabricated deck. High-lift blades create stronger vacuum for better bagging and leaf mulching, but use more engine power and wear faster on dry, sandy conditions.

Fitment & Compatibility

• Deck size: 50 inches (measures 50” cutting width, not the blade length alone).
• Blade specs: Each blade is 16.5 inches long, 2.75 inches wide, 0.203 inches thick, with a 5-point star center hole and 7/8” diameter.
• OEM cross-reference: Toro part 110-6837-03 (OEM) or 110-6837 (older). Also fits some 50” Exmark and Scag decks using the same blade pattern—verify your spindle mount is a 5-point star.
• What to check before buying: Measure your current blade length (from tip to tip), confirm the center hole shape (star vs. oval/diamond), and verify your deck model—this fits TimeCutter SS4225, SS5000, MyRide, and XLS 50” decks. Not for 42” or 54” decks.

Key Things to Know

• Installation: Straightforward—remove one bolt per blade, swap, and torque to 70–80 ft-lbs. No special tools beyond a socket wrench and blade removal tool (or block of wood to hold blade).
• Balance: These are factory-balanced, but always check balance on a blade balancer after sharpening. An unbalanced blade vibrates the deck and wears spindle bearings.
• High-lift trade-off: Better grass lift and bagging, but they’ll dull faster if you mow over sandy soil or often hit rocks. Expect 25–30 hours of use before needing sharpening.
• Common gotcha: The star center hole can be tight on some spindles—use a light lubricant (WD-40) on the spindle shaft if it’s stubborn. Never hammer the blade on.

Should You Buy It

If you own a Toro TimeCutter Z with a 50” deck and want maximum bagging performance or need to handle thick, wet grass, this set is a solid, cost-effective alternative to OEM blades. Skip it if you only side-discharge or mow on sandy, abrasive turf—standard or low-lift blades will last longer and require less frequent sharpening.
