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

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.

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.
