Rotary Mulching Blades Set of 2 21-5/8" — Heat-Hardened Steel, Direct-Fit for Toro/Oregon, Patented Mulch Profile

Rotary's set of two mulching blades is a direct-fit replacement for several Toro/Oregon part numbers, engineered to shred clippings finely and disperse them back into the lawn for cleaner mowing and improved turf appearance.

These are a matched pair of mulching blades produced by Rotary to replace Toro numbers 106-2247-03, 106-8744-03, 110-6568-03, and 110-1857-03 (also compatible with Oregon 96-396). Each blade is heat-hardened in the USA and manufactured to the exact dimensions needed for reliable fit and consistent mulching performance. They work effectively as mulchers even without a mulch plate and should be installed and used as a set to retain balance and cutting quality.

How do these blades improve mulching compared to standard mower blades?

Rotary mulching blades have a patented profile and cutting edge geometry that lift, cut, and recirculate clippings multiple times inside the deck, producing finer particles that settle into turf without noticeable residue. The design reduces visible clumps and helps grass recover more quickly after mowing.

• Patented cutting profile for repeated re-cutting of clippings
• Heat-hardened steel for longer edge retention
• Finer mulch particles that decompose faster in the lawn

Will these blades fit my mower and what are the exact dimensions?

These Rotary blades match the listed Toro and Oregon part numbers and are sized to the following specifications so you can confirm fit before purchase. They are intended for spindles with a 5/8" mounting hole; verify your mower’s mounting bolt size and blade length for compatibility.

• Overall length: 21-5/8" (550 mm)
• Blade width: 2-1/2"
• Material thickness: .160" and 5/8" mounting hole

Can I use these with a bagger or without a mulch plate?

You can install these blades with a bagger or use them for dedicated mulching; however, expect different clipping distribution depending on setup. With a bagger attached, roughly one-third of clippings will go into the bag while the remainder is recirculated into the turf, especially when grass is at normal mowing height.

• Works as a mulcher without a mulch plate
• Partial bagging: about 1/3 of clippings collected with bagger
• Very tall grass may show more visible clippings

How should I install and maintain these blades for best results?

Install the blades as a pair to maintain balance and even cutting performance. Keep edges sharp and inspect mounting holes and blade surfaces for damage after any heavy impact; replace both blades together if one is bent or badly nicked to preserve mower balance.

• Always replace and install blades in matching pairs
• Torque mounting bolt to manufacturer specification
• Sharpen periodically and check for damage after strikes

Who is this for: Homeowners and lawn care pros who need a reliable replacement mulching blade set compatible with several common Toro and Oregon part numbers. These blades suit users who want durable, heat-treated steel replacements that deliver improved mulching performance, consistent fit, and minimal visible clippings when mowing regularly maintained lawns.
