This is a Genuine Manufacturer Approved Blade used on Riding Mower/Lawn Tractor. This Blade is sold Individually. It is a 3-in-1 blade for mulch, bag and side discharge purposes. This part is designed to circulate the grass longer so it can be cut into smaller pieces.

Two new blades on lawn tractor and new blade on lawnmower Lawnmower grass was nice and even. And no vibration being a new blade. I’m on vacation now I put one mulching blade on lawn tractor, just needed breaker bar to get off, got one on, with do other latter. They were the originals, unbelievable that it even cut the grass, so banged up and missing chunks of metal
Blades look great. And also like idea. Where it tells on blade grass side now.

Just what I needed
Right part and right time delivered. Had tried to obtain from local mower service company, but they wanted to wait to order till they had enough to make it worth while. After a month (not high mowing season) decided to find it elsewhere. Quick install and used right away. All good. Still 2 weeks later local company has not ordered.
Good quality, good service. Thanks

Mulching blades and drive belt
The parts arrived in excellent condition. It took a little longer than expected but that was fine. The concern I have is the the freight was $20.00 and that is absolutely ridiculous. I doubt that I will order from your company again.

Then I removed the old spark plug, then gapped the new one at 0.030 then installed it. I then used a nut and bolt to attach the mulch plug to the tractor.

Removed mower deck but first had to remove drive belt for blades by depressing tension pully and sliding belt off pulls.
Next pulled pins that held mower deck, pulled it out from under mower.
7/16 boxed end wrench and a block of wood to hold blade steady and new blades off and on in minutes.
Reversed steps above to put mower deck on, cuts so much better.
