Arnold Universal 21-Inch 3-in-1 Mulching Lawn Mower Blade

Loved the ease of installation. Removed old blade, used one bushing the same size as my mower blade bolt, used my old bolt and washer to attach to mower. The two side holes were very snug fitting which is exactly what you want. The blade is marked which side goes down. One tip... Remove the gas cap, use a plastic sandwich bag (leave it closed and zipped up) laid flat across the gas fill hole then replace the gas cap so the plastic seals the gas from leaking out when it's tipped over, then tip the mower with the gas cap ending up on the highest side away from the ground. Also use a block of wood (short piece of 2x4) wedged between the blade and mower deck to prevent the mower blade from turning. This process takes about 10-15 minutes. No experience necessary, honestly, you can do this.

This universal blade has been much better than others I have purchased, it seems to cut the grass at a even height even when very tall. Others tend to leave very tall parts after a single pass.

Not entirely universal.:-( I had to fabricate a mounting system for my mower. SinceMy mower is pretty standard (Troy built 6.25 hp, from lowes ) I'm concerned that this is labeled as "universal" instead of spend 2 hours with a dremmel tool modifying the blade mounting system to fit your mower. It does cut grass though.

Came late, overpriced, bad packaging, NON RETURNABLE!

This just doesn't quite fit the Yard Machine I got from Home Depot. Mine doesn't require the 2 side bolts but has a plate with 2 detents where bolts would go. The plate doesn't work well with the slots on the blade. My advice is to get the exact blade for your mower.
