Export thread

This mower is about four years old. A year ago I removed the blades and asked a mower shop to sharpen the blades ($15). This time I decided to sharpen these two blades myself when there appeared "mohawks" (see below). Found this hand held carbide device for $8 on line. Three rubs to each edge and twenty seconds later the blades sharpened nicely. Sweet! After reinstalling them, not sure I put them back properly but at least the sharpened edges contact the grass first. The grass now has a clean cut edge on examination of the cut blades.

PROBLEMS:

1. There's a slight clicking sound as they rotate, but it's getting less

2. The grass still "mohawks", that is despite mowing the in the usual pattern done in past years, often a very narrow band of taller grass remains. It was this "mohawking" which prompted my sharpening these blades. Sharpening maybe reduced it a little. What causes this ?


I looked on-line and at the manual, and all it states is to put them back the way they were installed. Duh. I didn't pay attention. Where may one find a picture of proper blade placement ?

* As a separate question, how best to clean the underside from all the grass accumulation ? Wooden stick ? Spatula ? Is it okay to spray water in the area when the mower is on its side ?

* And yet another question. I enjoy using AMSoil Synthetic products in my car (260,000 miles). May I use AMSoil 10-30 Synthetic oil in this mower ?

* I've heard debates on blade sharpness. How important is it for these blades to be sharp, and how sharp should they be ? The lawn mower professional who sharpened the blades a year ago said that the blade need not be sharp to cut grass.

Thank you,

Mark

The blades kinda fit together, the bigger of the two on bottom. As far as cleaning the deck, tip on its side toward the exhaust, and spray out with a pressure washer or just scrape clean. Now for the "lawn professional" who said the blade does not need to be sharp to cut the grass is true BUT it doesn't really cut it, it bludgeons it. A sharp blade is essential in keeping grass alive and healthy. Dull blades cause yellowing (dead tips) so keep your blade sharp and it will keep your lawn healthy and green.

I agree. :thumbsup: See the post below I copied from an older thread to show what I use to clean the mower deck.

I just wanted to post back in this thread to tell you what I use now. I got a new putty knife when I bought my Honda HRX mower that is made especially for cleaning mower decks. It works better than the one I had (the one on the left in the picture) since the new one (on the right) has curved edges.

I would be scared to use a pressure washer because there is the possibility to get water where it shouldn't be, but that's just me. Blades should be sharp, but not overly sharp, just not dull.

Blade goes like this:

Double-check and make sure the blades, bolts and special washers are correctly installed. Carefully inspect the gap between the blade tips and mower deck and see if the blades have been striking the mower deck or contacting somewhere.

Click to expand...

Confirm mower height settings. Confirm blades installed correctly and sharp. Try lowering front OR rear wheels one click. Try mowing when the grass is a bit shorter. Mow only dry grass.

MowerMark said:

Click to expand...

Depending on the model, blades will be stacked right on top of each other, or offset just a bit. Here are two examples:





When installing the blots, use a torque wrench and tighten to the spec for your mower. Share the serial number off the back of the mower deck (MXXX-1234567) and I can direct you to a copy of the owner's manual where the blot torque spec is published for your exact mower.

Click to expand...

Let the engine fully cool off before cleaning. Hot bearings expand, allowing water to get trapped inside and will rust. For a Honda mower, tip the carburetor/left side UP. If you tip the muffler/right side up, it will leak fuel and oil will foul the air cleaner.

MowerMark said:

May I use AMSoil 10-30 Synthetic oil in this mower ?

Click to expand...

Any type of SAE 10W-30 is fine, synthetic or petroleum-based. Do not buy into the argument you can extend the change interval with synthetic, however. Always change the oil per the maintenance schedule (usually 50 hours, 25 if used under heavy load or very hot >90ｰ F environment)

MowerMark said:

How sharp should they be ?

Click to expand...

Not "razor" sharp. They will quickly dull. Sharpen at about 30-40 degrees, and the edge itself should be about 0.1-0.3 mm (0.004-0.012 in) thick

Thank you, Robert of Honda !

Some clarification questions please.

1. From where did you get those blade depictions ? I couldn't find them.

2. The center nut seems to do nothing on my mower. Is doesn't hold either blade in place. Is this correct or is a part missing ? What does this seemingly useless nut do ?

3. Do you approve of a water stream cleaning in the underside pan if and when the mower is cool ?

4. Is there a spray one may use on the clean metal to help prevent adherent grass cuttings ?

5. RE: 10-30 motor oil, would this be the same oil type I've been using in my Toyota Sedan ? Or does one use "small engine oil" ?

6. When buying new Honda replacement dual blades, are they pre-sharpened or must one sharpen them first before installing ?

7. Are replacement bolts available ?

MowerMark said:

Shop manuals...they are available from Honda (paper only) via eBay or Amazon.

MowerMark said:

Click to expand...

The big nut in the middle holds on the blade holder, but not the blades. The big nut does NOT need to come off to remove the blades, just loosen / remove the two outer bolts and special washers.

MowerMark said:

3. Do you approve of a water stream cleaning in the underside pan if and when the mower is cool ?

Click to expand...

Yes. Avoid spraying water on the engine directly, but under the deck is just fine.

MowerMark said:

4. Is there a spray one may use on the clean metal to help prevent adherent grass cuttings ?

Click to expand...

Not that Honda recommends. A good cleaning after each mowing is best medicine.

MowerMark said:

5. RE: 10-30 motor oil, would this be the same oil type I've been using in my Toyota Sedan ? Or does one use "small engine oil" ?

Click to expand...

SAE 10W-30 is a the same as what you'd put in a car. Just fine to use an "auto" oil for your mower. Just make sure it's marked "SAE 10W-30" and you'll okay.

MowerMark said:

6. When buying new Honda replacement dual blades, are they pre-sharpened or must one sharpen them first before installing ?

New blades are already sharpened from the factory.

MowerMark said:

Yes, have the serial number off the mower deck when shopping, as all parts lookup systems need that number to match the correct parts to your mower.

The Honda replacement blades from Home Depot seemed quite dull so I had them "professionally" sharpened before use. Was this not advisable ?

My model number is HRR2167VKA and serial MZCG-822xxxx. Honda's website was confusing because that "7" was missing from the model number: Honda Lawn Mowers: HRR216VKA, HRR216K8VKA

Is this the wrong link for my mower ?

Please suggest that Honda put the blade pictorials in the owner's manuals.

(BTW, it's impressive how this mower starts with the first cord pull.)

The flat blade without wings goes on top of the two blades. To sharpen take an vice.grip secure the blade to the table and an angle grinder make a nice smooth shiny surface using the factory angle. Razor Sharp is nice but you need to sharpen more often (I do because I have the time)

On my hrr a screw that holds the sheet metal belt cover came off close to the chute that piece of metal got sucked into the blade I needed to resecure it that was the clicky sound on mine.

I also recommend the micro cut over the quadrant cut blades because the quadrant cut just sucks

The micro cut are the offset blades and quadracut are the stacked blades swing by home depot pick up a box 30$ says they are for the hrx but I've used them for a long time no issues. There is only one piece of sheet metal like mentioned before tip the mower down carb up. Get leather gloves manually spin the blades see if it touches anything. Wiggle the sheet metal see if it moves at a if so there will be a empty screw hole

Your mower (HRR2167VKA) uses QuadraCut blades; MicroCut blades are similar, but not approved by Honda for use on your mower. Honda recommends using only the correct blades for your mower, period.

Be sure to use a torque wrench when tightening blade bolts; they are structurally part of the mower, and too tight will strain parts, too loose, and, well, we don't want too loose either.

The part numbers are:
Upper Blade 72531-VE2-020
Lower Blade 72511-VE1-020

Bolts are 90105-960-710 (need 2)
Special Washers are 90502-VG3-000 (need 2)

By using the correct blades, you don't have to worry about impact, rubbing or fit. This assumes you do not have any damage to the deck that would cause interference.

They don't approve because they want the hrr to be more innefficent than the hrx ... Rly they work fine the 7 is the version of the mower when you get new blades you can use them out of the box I grind the coating off personally just keep the stock angle

The micro cut blades on my hrr made such a huge difference in both mulching (the quadracut blades would leave clippings) and bagging and just quality of cut.

2a) The blades might wear down quicker...the way you buy them is just fine.

2b) The number after the '216' is the version, it is common for that number to be missing on websites.

I don't know if that's the mobile version of the Honda website, but when I look at it, it looks like this: Honda Lawn Mowers: HRR216VKA, HRR216K8VKA

Thank you. What could go wrong by using the MicroCut blades ? If they cut better and cleaner than the QuadraCut, why not use them ? May I get the MicroCuts from Home Depot or Orchard Supply Hardware ?

Re: Thank you, Robert.

Thank you, Mod. Nice name = LawnKing.

Not sure what could go wrong there is probably some reason. Bottom line is I've used them for a long time and will continue to use them. And I get mine from home depot because there is not a Honda dealer close to me

Re: Thank you, Robert.

Click to expand...

Your specific mower was never tested with MicroCut blades, so the engineers did not approve them for use with your exact mower. FYI, later versions of the HRR models (with a "9" in the model name) were updated to use the MicroCut blades. Unofficially, they would probably work just fine with your older HRR model, but again, not technically approved by Honda.

MowerMark said:

Direct from Honda, the blades meet all the production specs and quality control checks. While a pro could easily make them "more sharp" that won't necessarily improve cut or finish performance. Remember, too sharp and the blades will get dull very fast. Too dull and cut quality will suffer. The factory edge is the best compromise between quality and sharpening interval.

Honda mowers do not have model years, but use a code called a K-number to designate running changes. Your mower is a "K7" and is currently at the "K9" version. Honda does not always include the K-number in all ad, print, and web names. The K-number is more for Honda internal use, and you should use the frame serial number to locate any parts, service, documents, etc. for your exact model.

MowerMark said:

Should be correct, if I'm reading your serial number right. Double-check and you'll see a link that has a manual for your serial number.

Thank you. Since you term those MicroCut blades as an "update", and another member here prefers them, I'd like to try them.

• Are the MicroCut twin blades available from Home Depot or Orchard Supply Hardware, and if so, what are the part numbers ?

• A threshold question is: Will the use of Honda's MicroCut blades VOID the mower's warranty ?

I couldn't find a blade diagram in the product literature accompanying my new mower, so your diagram was very useful.

Nice to know about this model number coding, but for the consumer this letter inserting only gives confusion. Suggest that Honda either disclose to the consumer this date code or revision nomenclature, or disclose to the consumer to ignore the extra character and/or relabel their products to have a separate date code, leaving model numbers identical. Another way to better handle this confusing point is to indicate in your manual "If your model number starts with HRR216 and ends with VKA, then ……… ". Ignorant consumers look for exact model number matches, and will not always forgive an extra unexplained letter or number.

• How does a homeowner know when the blades need sharpening ? The smooth to ragged edge of the cut grass ? Feeling the blade edge with the finger ?

Your warranty will remain intact no matter what; it can't be "voided." However, if the use of incorrect parts is determined to be the cause of a problem or failure, Honda will not pay for warranty repairs to fix that specific problem. The warranty only covers factory defects.

Click to expand...

In the owner's manual is an illustration showing what to look for when inspecting the blades. Over time, you'll learn to recognize dull blades from the finish quality of your lawn. Depending on how much the mower is used each year, a lot of customers elect to have the blades sharpened before the mowing season starts. This may be too frequent or too little for your lawn.

Do NOT use your hands or bare fingers to inspect or test a blade. Always wear heavy gloves when working around the blades to protect your hands.

You can learn a lot more by reading the owner's manual; it has many more details on how to get the best results from your mower, while safely operating it.

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 ?

The microcut is soooooooo much better than quadrant cut.... There is simply no competition like a race between a snail and a dodge viper....

Okay, but what makes it much better ? Wear ? Cutting ability ? Less noise ? Is it worth $8 more ?

Is the Microcut the recommended blade for your model ?

Mulching with it is the big difference doesn't leave grass clippings. It's also better at bagging. The cut quality is much nicer and the cutting blade can be sharpened more times

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

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

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.)

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.)

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 ?

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.

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

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.

MowerMark said:

Click to expand...

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 ?

Look on the serial number plate (rear of the mower deck) on your mower. The full model name will be there. If you see the "9" in the name, you got the right blades. If not, you should return them and get the factory-recommended blades that match the ones that came with your mower. Look for part number 08720-VE2-001.

MowerMark said:

A small door/shutter that lets you choose to mulch or bag. It's a green lever on the rear of the mower deck. If you do not have one, you for sure do not have have a K9 mower, and need the different blades.

MowerMark said:

Click to expand...

No. The washer is curved and has some spring built-in. Compare an old one to a new one. If they are the same shape, you can use the old one. Eventually, the old one will start to get flat (no spring) and should be replaced.

MowerMark said:

When working around the blades, you just don't want to take any chances. Disconnecting the spark plug cap is 100% effective against any possible accidental engine start.

MowerMark said:

Provided nothing else fell or or came apart (varies with models) just tighten it back securely. Not usually an issue.

Typically, you'd tip the mower over on its right side wheels to service the blades:

"smaller blade" = thinner blade = upper blade = "blade against the engine"
The upper blade sits 'on top' of the lower blade.

So the wording on the box could be better.

Robert, as per my signature my model is the HRR2167VKA, but I want to try the Microcut blades which will fit but as you said "not tested by Honda". Does Honda NOT make any Microcuts which will fit the HRR2167VKA ? In another post we had this discussion where it was admitted that Microcuts would fit in my model mower. The factory-recommended ones have always been only the Quads, but I want to try Micros if they won't damage my mower. Several people have indicated the Micros cut better. Does Honda have Microcuts safe to use in my HRR2167VKA, even if "not tested or not recommended" ? If so, what are the part numbers ?

My model does NOT have a green door. Should I buy a new mower ? What will happen if I use Micros and don't have a green door ? I never use mulching.

RE: "Spring". Do you mean it has a separate coiled "spring". Never have seen a spring. Perhaps you mean resiliency. Why is this "spring" important ?

Now that you know my model number, why the warning now to remove the central nut ? I did remove it once then screwed it back it. Didn't seem to do anything.

The MicroCut blades you bought will technically fit your mower, they are just not officially recommended by Honda for that model.

If you are happy with the performance of your mower, keep it, of course. The Clip Director feature just makes it simple to switch between mulching and bagging. Does not sound like that's necessary for you. You may notice some change in the finish of your lawn when using MicroCut blades, or you may not. It can be very subtle, and often depends on the type of grass, moisture content, and many other factors. If you don't like the change, just go back to the stock QuadraCut blades (FYI, they can be sharpened by an lawn mower shop).

MowerMark said:

Click to expand...

No actual spring, but the washer is slightly curved/cone-shaped (often called a "spring washer"), and is designed to bend/spring when the bolts are tightened, applying pressure against the bolt face and help retain the bolt. Just a bit more security for holding on the blades.

Provided nothing else came off or loose when you had it out, there should be no problem.

Bit confusing here. On one hand you were telling me "you should return them and get the factory-recommended blades that match the ones that came with your mower. Look for part number 08720-VE2-001." But on the other hand you indicated that the Micros will fit and work on my model. If the Micros will fit AND work on my model why "should: I return these Micros and get the old Quads back ?

One of the reasons I want to try Micros is that I'm still getting lines of grass not cut short/even, which I've called "Mohawking". I've tried cleaning the mower, collection bag, and blade sharpening with no help in solving the Mohawking.

Since Quads are being phased out, would you kindly ask Honda to test the Micros to see if they will approve them for these older machines ?

After reading all this. OMG the same thing was asked and answered 6 different ways.

The best answer is the micro blades will fit and work on your mower.
Put the smaller blade on first then the bigger blade. Cut the grass if you like how they cut then keep them if you don't then try some other blade.

I said the QuadraCuts are the Honda-approved blade, but you mentioned you wanted to try the MicroCuts anyway. The MicroCut blades will indeed mechanically fit, but I can't say for a fact they will change the finish or quality of cut on your lawn. Since you already bought them, I'd suggest you try them and see if they make an improvement.

MowerMark said:

Absolutely. Honda has a number of customers ask about using new-style MicroCut blades with an older HRR model normally fitted with QuadraCut blades. When I have a formal answer, I'll share it here.

Fantastic. Thank you.

BTW, today I called Honda and it was not a good experience. One presses a number to buy parts, and finally one gets an announcement that you cannot buy parts. You press another button to talk to someone and it announces you should go to a dealer. Another button ---> dead end. Finally you can press another key and you get to someone who knows very little. Is there a good HONDA telephone number which actually gets one through to a knowledgeable person, or does Honda push all customers to dealers ?

Sorry to hear of the poor experience, Mark. The 770-497-6400 number is the only one for Honda Customer Relations (Power Equipment, Engines, Marine).

Dealers have significant years with the products, and are typically quite knowledgeable about local conditions, turf-types, environment, etc. Honda does indeed rely on them to be the first-line of support, but understands some people want to talk to the manufacturer, or may need to, if the dealer is not available. Still, there is no substitute for first-hand experience and I'm confident your local Honda dealer can help in the future. It can usually be a positive relationship, and if you become part of their business, they will remember and support you first in the future. You can find a local dealer using this link; be sure to check off LAWN MOWERS and enter your ZIP code:

Yes ! That was the number I called today. Recorded announcement tree needs changing. The first announcement should indicate that no parts be ordered and that no customer assistance can be obtained, and that you must obtain assistance from only your local dealer. It's silly to be offered choices which are not available.

Actually, many questions. But that is one of the values of this forum. Toro, Orbit, and other companies are good at answering questions when one calls the corporate office. Honda was not.

Robert, please talk to your Honda company re: blade packaging

Robert of Honda:

Wasted one hour. In order to help customers, store return personnel, and salespeople, and prevent unnecessary returns to your distributors, please ask your company to do the following to the packaging of UPC 844053010834 SKU 1000-027-621:

1. Clearly label that the two blades are different in shape and coating. One is glossy, one is matte.

2. Change the installation diagram to reflect the shape of the blades. The diagram is accurate for only one of the blades. The large bent wings are not depicted.

Thank you.

New Honda Quad blades work best if sharpened

Robert of Honda:

In a prior post you indicated that out of the box, new Honda blades don't need sharpening. The edges did not seem sharp like the Micros. The Quad blades out of the box did cut the grass, but the grass cut was irregular, yellowish. The blades retained a black film on the sharper edges of the blades. I used a $7 hand-held carbide sharpener on the blade edge and some black film (not metal) was removed and the blade was sharper.

The blades now cut much better.

Do the Quad blades from the factory have a black coating over the cutting surface ?

Your opinion alone has some merit. Have you examined new Quads ? I took pictures of this uniform non-metallic material which curled up upon scraping and disclosed the bright metal. Perhaps I'll post them, but certainly from this point onward will run this sharpener on new blades.
