110-6837-03 Mulch Blade fits for Exmark 50' Quest 115-5059 115-5062 Blade Replacement for Toro Time Cutter Z Mowers with 50'' Deck Z5000, 74370, 74372, 74373 3 Pack

What It Is

This is a 3-pack of 110-6837-03 mulch blades designed for 50-inch cutting decks on Exmark Quest and Toro TimeCutter Z5000 zero-turn mowers. They replace OEM part numbers 115-5059 and 115-5062, and are intended for mulching grass clippings into fine particles rather than side-discharging or bagging.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Only fits 50-inch decks. Measure your deck width from blade tip to blade tip.
• Model compatibility: Direct fit for Exmark Quest 50" (models 74370, 74372, 74373) and Toro TimeCutter Z5000 with 50" deck. Does not fit TimeCutter Z4200, Z5400, or other deck sizes.
• Blade dimensions: Each blade measures 16.5 inches long, 2.5 inches wide, with a 1-inch center hole and 0.25-inch thickness. Confirm your existing blade matches these specs.
• OEM vs aftermarket: This is an OEM Toro blade, not a generic replacement. That means exact fit, but higher price than third-party options.

Quick check: Remove one existing blade and compare length, hole size, and thickness. If they match, these will bolt on.

Key Things to Know

• Mulching vs. standard blades: These have a more curved profile and extra cutting edges to recut clippings. They work best with a mulching plug installed and dry grass. Wet or tall grass will clump.
• Installation: Straightforward—remove the old blade, clean the spindle, and torque to 70-85 ft-lbs. No special tools beyond a socket wrench and blade removal tool. Always disconnect the spark plug first.
• Sharpness out of box: These come sharp but not razor-edged. Expect decent performance for 10-15 hours before needing a sharpen or replace.
• Common gotcha: Do not mix these with standard discharge blades on the same spindle—uneven cutting and vibration will result.

Should You Buy It

If you own an Exmark Quest 50" or Toro TimeCutter Z5000 with a 50" deck and want OEM-quality mulching blades that fit without modification, this 3-pack is a solid value. It’s not for side-discharge or bagging use, and you’ll need to keep grass dry and deck clean for best results. For anyone mulching regularly on these specific mowers, it’s the right choice.
