MaxPower mulching blades 42" John Deere fit – 2-blade commercial set, 21-3/8" USA-made, powder-coated

MaxPower 561811XB is a USA-made two-blade commercial mulching set engineered to replace OEM GX22151 and boost mulching performance on many 42" John Deere 102, 115, 125 and 135 riders.

This replacement set includes two full-length commercial mulching blades manufactured to meet or exceed OEM specifications. Each blade measures 21-3/8" long by 2-1/2" wide and uses a seven-point star center hole to fit a range of John Deere mower spindles. Built with a wider cutting surface and sharpened teeth, these blades are powder-coated after production for corrosion resistance until first use.

Will these blades fit my John Deere 42" cut mower?

These blades are designed for many John Deere models with a 42" cutting deck, including model families 102, 115, 125 and 135. Always verify fit by comparing the OEM part number on your existing blades to the compatible numbers listed for this product.

• Fits 42" decks on John Deere 102, 115, 125, 135 riders
• Replaces OEM GX22151, AM137328, AM141033, GY20850, UC21583
• Uses a seven-point star center hole for correct spindle alignment
• Measure your current blade: 21-3/8" L × 2-1/2" W to confirm fit

How do these commercial mulching blades improve clippings and cut quality?

MaxPower mulching blades increase cutting surface area and have sharpened cutting teeth to chop grass more finely, which produces finer clippings that resettle into the lawn. Their centrifugal air lift design keeps material moving under the deck for more uniform distribution of clippings.

• Wider cutting edge for improved mulching action
• Sharpened teeth for cleaner, more consistent cuts
• Centrifugal air lift promotes even chopping and distribution
• Powder coat protects blade until first use, where coating wears off

What are the build quality and durability features of the 561811XB blades?

Manufactured in the USA to match or exceed OEM tolerances, these blades are hardened and sharpened during production to ensure a precise edge straight from the factory. A powder-coating step provides temporary protection from corrosion and handling nicks prior to installation.

• USA-made to OEM-compatible specifications
• Factory sharpening for immediate performance
• Powder-coated finish for shipping and storage protection
• Robust center-hole design for stable mounting

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

Install according to your mower owner's manual, matching blade orientation and torque specifications for spindle fasteners. After the first cut, the powder coat will wear away; periodically inspect for edge damage and balance, and sharpen or replace when necessary to preserve cut quality and mower health.

• Follow OEM torque and orientation instructions during installation
• Inspect blades after the first use and at regular intervals for chips or bends
• Sharpen or replace blades to maintain a clean cut and even deck balance
• Keep safety gear on and deck disconnected from power before servicing

Who is this for: The MaxPower 561811XB two-blade mulching set is intended for homeowners and commercial users who own compatible John Deere 42" ride-on mowers and want a durable, factory-sharpened replacement that improves mulching performance. It's a good match for operators replacing OEM GX22151-series blades or anyone seeking blades manufactured to OEM-equivalent standards and ready to install out of the box.
