Proper dual blade installation on this Honda mower, and a few other questions.

[exotion]

So no problems from using these non-recommended blades ?

Will their use void any warranty you have ?

How do you sharpen those blades ?

No problems. I sharpen them once a week I tip mower on it side carb side up. Remove blades I vice grip them to my shop table and use a 4 1/2 inch grinder to sharpen. I use a small cheap plastic cone balancer to make sure balance is close I don't think it needs to be perfect reinstall. Takes about 10 mins to sharpen

Also I have no idea about warranty I do all my own work

Thanks. How often is the balance off ? If it's not balanced, is it difficult to balance ? Does an unbalanced blade make a noticeable difference in vibration ?

It gets off balance when you hit sticks rocks and suck it knocks the blades. It's not hard to balance using the cone you just.sharpen the heavier side a little more.

Balance is not noticible until its really off balance and.cause damage to your machine if.it vibrates

Thank you. Will exchange the Quad for the Micro tomorrow and give follow-up in this thread.

Ooops. Looks like I messed up. I purposely purchased a set of Quadracut blades thinking they were different from the factory-installed. Looks like in error I purchased the "proper" blades but your numbers listed above are NOT on the box. This new box has 08720-VE2-001 and SKU 136-418 and UPC 844053009753. Are these the Honda factory recommended blades for my mower ?

Robert, I'd like to try the more expensive Microcut blades. How are Microcut's different from Quad's ? Do the Quads cut cleaner ? Why are Quads less expensive ? Why don't the newer mowers use Quads ?

That part number is a "kit" part number, and the kit contains two blades; part numbers 72511-VE1-020 and 72531-VE2-020. These are QuadraCut blades for many different mowers, including all models of the HRR216 from K0 through K8. Starting with the K9 version, all HRR mowers moved to the MicroCut blades. You can look at the serial/model sticker on the back of the mower deck and tell the K-number for your mower; it is the digit right after HRR216, i.e., HRR216*VKA or HRR216*VLA, etc.

Quadracut blades are stacked on top of each other, with the blades cutting at the exact same location. MicroCut blades are also stacked, but are slightly offset, so the lower blade cuts first, then the upper blade slightly behind it.

Be sure to wear gloves when working around the blades. Use a 2 x 4 or other piece of wood to block the blades and prevent them from turning when removing/installing. Always use a torque wrench when tightening the blade bolts (36-43 ft-lbs.)

I usually use my foot same for taking the blades off

Thank you again, Robert. Do the Quads cut cleaner ? Why are Quads less expensive ? Why don't the newer mowers use Quads ? Why did Honda change to Microcuts ?

Do the Quads cut cleaner ?

Generally, the staggered (offset) placement of the MicroCut blades provides an overall superior finish on most lawns. It's more about their position, as the MicroCut and QuadraCut blades are essentially the same shape/size.

Why are Quads less expensive ?

Suppliers, manufacturing, inventory levels, tooling, raw material cost, etc. all figure into cost of a blade.

Why don't the newer mowers use Quads ?

QuadraCut blades were phased out with the most recent updates to the HRR series. Now all new model twin-blade Honda mowers use MicroCut blades.

Why did Honda change to Microcuts ?

MicroCut (offset layout) provides a better finish under most conditions. MicroCut has been around for many years, and it was always offered on the best models (HRX). Honda wanted to reduce confusion and equalize blade technology on all twin-blade mowers, so eliminated QuadraCut and fitted the effected models with MicroCut.

All read and appreciated. You are awesome.

There were TWO different packages of Microcuts @ Home Depot. Confusing. I purchased:

08720-VLOPS00
Replacement Blade Set for Honda HRR Models with Clip Directorｮ
HRR2169PKA
HRR2169VKA
HRR2169VLA
HRR2169VYA


Are these the proper set ?

What is a Clip Director ?

Does one need to use a NEW washer every time ?

Why remove the spark plug cap ? The engine can't start by itself.

What happens if the center bolt is removed but the tightened back on ?

The box directions could be improved: "The smaller blade goes on top? The "on top" is not defined and seems to contrast with "the smaller blade against the engine". Against the engine ? Huh ? Does Honda mean "closest" to the engine ?
