Good quality, genuine JD part
Worked well. Interesting that the old, worn out blades someone lost over 1" on either end. but the new ones are fine.

Perfect replacement for John Deere 125 Automatic w/42” deck.
Review of John Deere Original Equipment Mower Blade Kit #GY20850 I ordered these to replace the blades on my John Deere 125 Automatic with the 42” deck. They fit perfectly and seem to be heavy duty. Time will tell. Feel perfectly balanced too. They are as described in the ad/description.

OEM Product
Replaced my original blades after several years. These are the exact same blades that the tractor came with. It’s important to use OEM to keep the overall balance of the tractor deck. Worth the extra money for this quality.

Be aware
Product is of good quality; however be careful to insure that it is the right blades because of the design of the sprocket holes that fit the blade to the spindle!

Great 3-in-1 replacement blades.
Great 3-in-1 replacement blades. My John Deere hasn't cut glass so well in several years.

Buy the best which is JD.
Always use John Deere mower blades. Why bother to have your old blades sharpened when they could be out of balance and stressed. No regrets with JD original blades.

Ho acquistato questo set di lame per il mio John Deere X125 che le aveva usurate e deformate. Dopo non poche difficoltà per smontare le vecchie lame (tramite una chiave da 15/16”) ho installato le nuove…praticamente, un altro trattorino: vibrazioni sparite, taglio ineccepibile, tutto perfetto!
