ILONPA 48" 7-Star Mulching Blades for John Deere 100-Series 2-Pack — 3-in-1 High-Lift, Corrosion-Resistant

These are ILONPA GY20852 7-star center mulching blades designed for 48" John Deere decks, offering bagging, side-discharge and mulching performance in a durable 3-in-1 blade profile.

Replace worn or damaged cutting blades with a set engineered to match John Deere 100-series 48" decks and many residential EZtrak zero-turn models. These blades feature a 7-point star center hole to fit specified spindles, a curved 3-in-1 profile for repeated clipping circulation, and protective edge paint to reduce corrosion during storage and initial installation. Read the compatibility notes carefully to confirm the center-hole pattern before ordering.

Which John Deere models will these ILONPA blades fit?

These blades are made to fit a wide range of John Deere lawn tractors and zero-turn mowers with a 48" deck from the 100 series and several residential EZtrak models. Check your deck size and center hole type — they use the 7-star pattern, not a circle center hole.

• Fits many 100-series tractors including 145, 155C, D140, D150, D155, D160, E140, E150, E160, E170, S140, S160, X140, X165–X167 and similar models.
• Compatible with select EZtrak zero-turn mowers such as Z245, Z255 and Z355E with 48" decks.
• Replaces OEM numbers GY20852, GX21784, GX21785, GX21786, AM137757 and AM141035.

How do these 3-in-1 mulching blades perform on grass clippings?

The curved, high-lift geometry breaks clippings into finer pieces, allowing you to mulch and return organic material to the lawn, or use side discharge and bagging modes as needed. The blade’s shape promotes better airflow and clipping recirculation for a cleaner cut and more consistent finish.

• Mulches by recirculating clippings for smaller particles and faster decomposition.
• Works with bagging and side-discharge systems for flexible cleanup options.
• High-lift profile improves clipping evacuation and deck performance.

What are the blade dimensions and mounting specifications?

These blades follow the dimensions needed for many John Deere 48" decks: 17" long, about 2-5/8" wide and 1/6" thick with a 7-star center hole sized 7/8" (22.2 mm). The listed air lift height supports normal deck airflow and cutting action.

• Length: 17" (432 mm); Width: 2-5/8" (67 mm); Thickness: 1/6" (4 mm).
• Center hole: 7-point star, 7/8" (22.2 mm) diameter; air lift ~1-1/7" (29 mm).
• Type: 3-in-1 mulching blade intended for 48" decks.

How do I avoid ordering the wrong blade for my mower?

The critical detail is the center-hole pattern: these ILONPA blades use a 7-star center hole. If your mower spindle accepts a circular center hole, this set will not fit — in that case, search for the circular-center replacement part (MPN M145476) instead.

• Verify your deck is 48" and check the spindle center hole shape before purchase.
• Compare OEM part numbers listed here with your mower’s manual or existing blade stamping.
• Contact ILONPA support if you need help confirming fitment or part compatibility.

Note on packaging: this listing title denotes a 2-pack; manufacturer details also reference blades in the package. If you need precise counts for an application, contact us or ILONPA customer service for clarification before installation. The cutting edges are painted for corrosion protection and installer safety; this paint will abrade away quickly in initial use and does not affect blade performance.
