I put a fresh pair on every year and have the old ones sharpened. After doing it a few times I can get both blades replaced and the deck hooked back up in about an hour with minimal deposits into the swear jar. They cut and mulch great. Great value. Hefty blades, feel very solid. Review: Awesome cut...even in thick wet grass!! NO CLUMPING!! BUY THEM!!! - These blades are awesome! Over the years I've tried all of the fancy Laser Edge, Oregon Mulching, Tri-Cut, Super Touch, Tri-Fecta, does everything...will cook you dinner type blades on my ZTR mower :) I'm not sure what makes these things different....but man, they cut awesome! I tried them out on a thick lawn that was wet from dew, and a few days past when I should have mowed it. The first thing I noticed was how smooth they were...no vibration at all (I usually check the balance on new blades before I install them...but these I didn't)......and they cut awesome! Not sure why the design is differnet from the other high end blades, but these things don't clump up at all....they blow out a fine mist of grass...no climbing, no chunks, nothing...even on thick wet grass. Super impressed with these blades so far. Not sure what the "magic sauce" is on them...the look pretty plain, but they sure cut awesome! I couldn't be happier with them!! These will be my go-to blades in the future!!! Not very expensive, and so far them cut better than any other blades I've tried over the years. They are awesome!! ## Features - Replaces OEM Part: John Deere GY20850, John Deere GX22151, John Deere AM141033 - GY20850 Mower Blades Dimensions: Length 21-3/8", Width 2-3/4", Center Hole 7-point star, Air Lift 1", Cutting Edge Length 5-7/16", Compatible Deck Size 42".

Great blades so far. *by F***R on August 24, 2026* Precision fit, high quality appearance and green powder coat. Came with. Thread lube . Sharp edges. These fit tight. Clean the decks inner edges-sides., hub/spindle, bearing, and mount pattern (5Star). Install one blade and carefully spin it several times, checking clearance. Clear enough tolerance so a bent deck edge on uneven rough ground doesn't catch a blade edge. Repeat for 2nd blade. I've only got about 2 acres cut on the new blades so a later review of quality, keeping a sharp edge, ease of sharpening and durability of powder coating may follow πŸ˜‰ Great value, so far, perfect! ## Frequently Bought Together - UDC Parts GY20850 Mower Blades for John Deere 42 Inch D105 D130 S100 S110 S240 X300 E100 E110 LA135 Replaces OEM no.
