ZALANA 110-6837-03 Lawn Mower Toothed Mulching Blades Set Replace 115-5059-03 112-9759-03 112-9759 115-5059 for Toro Timecutter SS5000 SS5060 MX5050 MX5000 MX5075 Z5000-50'' Deck (3 Pack)

What It Is

This is a 3-pack of toothed mulching blades designed to replace OEM Toro blades on select Timecutter and Z5000 zero-turn mowers with a 50-inch cutting deck. The aggressive teeth chop clippings finer than standard blades for cleaner mulching.

Fitment & Compatibility

Before buying, verify three things:

1. Deck size – Only fits Toro 50-inch decks. Measure your deck if unsure; a 50” deck typically has a 50” cutting swath.
2. Model number – Confirmed fit for Toro Timecutter SS5000, SS5060, MX5050, MX5000, MX5075, and Z5000-50”. Not compatible with 42” or 60” decks.
3. OEM cross-reference – Replaces Toro OEM part numbers 110-6837-03, 115-5059-03, 115-5059, 112-9759-03, and 112-9759. If your current blades have any of these numbers stamped on them, these will work.
4. Physical check – Each blade is 16.5” long with a 5-point star center hole and 0.25” thickness. Measure your old blade’s length and center hole shape to confirm.

Key Things to Know

• Aftermarket quality – These are not OEM Toro blades. Some users report slightly thinner steel or faster dulling than factory blades. Expect a 1-2 season lifespan under normal use.
• Installation – Medium difficulty. You’ll need a socket wrench and a blade removal tool (or block the blade with wood). Always disconnect the spark plug before working under the deck.
• Balance – Check each blade’s balance after installation. Unbalanced blades cause vibration and premature spindle wear. Use a simple blade balancer or clamp a nail to a bench.
• Mulching vs. bagging – These are strictly for mulching. If you bag or side-discharge often, stick with standard lift blades.

Should You Buy It

Buy if you own a compatible Toro 50” mower and want an affordable mulching blade set for a season or two of fine clipping chopping. Skip if you need OEM longevity, prefer bagging, or have a different deck size. For the price, it’s a functional budget option for light-to-moderate use.
