SuperDi Replacement for Toro Timecutter 50 Inch Blades 115-5059-03, 79016P, Z 5000 Series112-9759-03 110-6837-03 SS5000, MX5060, SS5060, 75759, 75755, 75753, 74632 Mower Mulching Blade （3 Pack）

What It Is

This is a 3-pack of aftermarket mulching blades designed to replace OEM Toro blades on 50-inch Zero-Turn mowers. Mulching blades use a curved, serrated edge to chop clippings finer, recirculating them into the turf for nutrient return rather than bagging or side-discharging.

Fitment & Compatibility

Check these before buying:

• Deck size: These fit 50-inch cutting decks only. Measure your deck width; a 50-inch deck requires blades around 20.5 inches long each (center hole to tip). Verify your existing blade length matches the listed OEM numbers.
• Model compatibility: Direct replacements for Toro Timecutter Z 5000, SS5000, MX5060, SS5060, and Z Master 75759/75755/75753/74632. Also fits Exmark and some Bad Boy models using the same pattern – confirm your OEM part number matches one of these: 115-5059-03, 79016P, 112-9759-03, 110-6837-03.
• OEM vs aftermarket: These are aftermarket (SuperDi), not genuine Toro. They use the same center hole (commonly 5/8-inch or 7/16-inch – measure yours) and bolt pattern. If your deck uses a 5-point star center hole, these won’t fit.
• Measurement: Each blade is about 20.5 inches long, 2.5 inches wide, with 0.2-inch thickness. Compare to your current blade before ordering.

Key Things to Know

• Quality: Made of heat-treated boron steel, reportedly durable. Edge holds up well in grass but may dull faster than OEM in sandy or rocky soil. Some users report slight balance issues – check balance on a blade balancer before installing.
• Installation: Standard process – remove deck, block blade, use a socket/wrench. Torque to 40-50 ft-lbs. No special tools needed. Mulching blades are heavier than standard blades; ensure your deck’s spindle bearings are in good condition.
• Common gotchas: These are mulching blades, not high-lift or bagging blades. If you frequently side-discharge or bag, they may leave clumps. For mulching, they work well. Also, the 3-pack covers a 50-inch deck (typically 3 blades), so you get a full set.
• Price: $37.88 for three blades is roughly half the cost of OEM Toro blades. Good value if you mow frequently and replace blades annually.

Should You Buy It

Buy these if you want a budget-friendly, direct-fit mulching blade for your Toro 50-inch ZTR (or compatible model) and primarily mulch clippings. They’re a solid value for the price, but avoid them if you need high-lift for bagging or if your deck has a non-standard center hole pattern.
