I bent a blade on my old lawn chief and thought that it would be an easy replace....but I can't seem to find the compatible blades anywhere....I can find what looks like it might work but none that i have seen seem to match up with the spindle hole shape??.....Will the star hole fit on my spindles???....the hole i have is NOT a star shape......I couldn't explain the shape..........the blades do have 6 point notched holes..... two
blade length and and two on each side of the blade... is there a universal i can use???.....the blades were on upside down when i bought this mower ...cutting edge never been used......that stump must have grown over the winter........any help will be appreciated ......

Let's start with the actual model number of your mower and deck size.

And probably you have one of the old after market blade holes that were to get around the MTD six point star patent. Here two of them.

The "H" or Double Diamond.

And the "Y" Design


The MTD six star will replace both as it is the original pattern

i have the H pattern on the blades and I have never found a model # on the mower anywhere....the sticker on the seatback was gone years ago from the looks of it........about all i can tell you is that is a lawn chief 14.5 hp ohv briggs..........42 in cut.....I have the blade straitened......I just need to try to hammer out the curve on the sharp side.......I can get by with what i have but i would like to have a couple of new blades for spares......Maybe now that i know that pattern is called H I can do a little better research.........thanks for the info.......

I googled H pattern 21" blade and many came up.

star tec said H or double diamond........ the H pattern apparently is not what i have, what I have is the pattern in his first pic.......now I guess I'll search for a double diamond......thanks for looking.....

Go to the Rotary , Stens, Prime Line & Oregon web sites.
Open their on line catelogue and search for "Lawn Chief Blade"
In most cases they will then list by blade length
When you find one that sounds like it might fit click on the "More" - "detail" or the actual name to bring up the full description, right clicking or what ever you do to make the new window appear in a new tab will make life easier .
Google does not search catelogues unless the business has paid them to do it
I have had luck by doing the same search in Jacks Small Engines , K & T Mower parts or Mennards
The first bunch are wholesalers & do not sell direct to the public so you will have to order through one of their retailers but they all have a "find a dealer " search on their home pages
I have found the Oregon blades to be the best made but their catalogue is fairly small , Stens & Rotary have the biggest & Prime Line closed down in OZ 8 years ago so can not remember what their blades were like .

That should be the "G" deck with two 21.25"/ 21-3/16" blades.

Thanks a lot for your time bertsmobile1.......I'll try that road and see how i do........Jacks small engines was out of stock [If Idid the search right}....I'll try your other
places..........I have a kitty cat trying to help me with this....he just decided to la down on the keyboard....;=+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

maybe my Google is different. There is also a bowtie mount which is similar but different. How about a photo of the actual blade center.

the blades that are in it are an exact 20 inches....[ I don't know that these are original blades??] the mower does a very good job mowing with these blades......I'll have to put them back on the deck and make sure that i have clearance for 21 3/16, that is the blade length on the ones in the add that you listed.................I'll check to make sure........but the pattern is the same..........thanks again for all the help........great bunch of guys.....I'll see if I can get a pic in the morning.......

Blade length is like TV or computer screen & measured diagonally from the tip of one cutting edge to the tip of the other side

I'm 74 and still learning!!.......I had NO idea..........sure enough.....21 and 3/16.........these blades were on this mower upside down when i bought it, the cutting edge never hit a blade of grass.........could be, that's why they sold it.......under the dust it was like new.........
now that I'm sure of length and spindle hole I can find what i need..........
thanks again to a great bunch of guys........
we are never too old quit learning.........

this is what I can up with.....apparently they have them in stock......I'm pretty sure these are what I need???

That should be the "G" deck with two 21.25"/ 21-3/16" blades.

what startech posted above, is the most likely answer. If you look at the sticker on your link and my link, they show the same MTD number.

It's been my experience that Oregon Durable blades are the best of all the aftermarket blades out there.

I don't know who made Lawn Chief but sounds like it is 50+ years old! You can't even say Chief anymore!
Photos of course are required here. With my Solidly mounted 5" Vise, a 24" PIpe wrench and 2' Cheater pipe I was able to bend one close enough to work. Within 1/8". Be aware that the blade could fracture so pick a nice landing spot for yourself. Any repair Garage should have a torch set which could heat it up and bend it quickly.
Let it cool naturally. Send photo of bottom of Spindle showing anchor pattern. It isn't the Space Shuttle.

I recommend crossing to a set of XHT Blades. I don't buy blades nearly as often as I used to, these are stronger than stock and last a long time. Hardened Steel.

I'll probably get in trouble over this but..........I always say cats are a lot like women...if they want something; they figure a good way to get it.......I had to go and check my order......I was happy to find the right hole and length ......I only saw made in usa and bought them....oregon had done well with chain saw blades for me...in the last few years.......

Digiacomo, if the picture of the H pattern is what have and a 42" cut your blades (new) will be 21 3/16" measured diagonally, yours maybe a little shorter because of wear, the Rotary # 1031 is a straight cut and # 1032 mulching blade.

That DOES reduce the sharpening requirements per season!

Bought several perfect mowers like this. Raise the deck up. Look at the blade. Another look at the blade. Nother look. WTF, blade is on upside down. Classic.......

Hammer, hammer, hammer

I used an 8 lb sledge and my anvil to get it straight, but you need heat for the bend in the cutter end, My torch tanks have been out of gas and oxygen for a couple of years, [ I went from steel work to wood turning, a very satisfying hobby ]...... new blades are cheaper than filling my tanks,,,,,

sounds like the original owner preferred to have his lawn have that beaten and battered look, rather than cut-n-trimmed.

I got my blades,........ opened package and the pattern was a star, OH SH!T.........THE star pattern worked great.....the blades might have been a little lighter than my originals, but the mower doesn't care......

thanks for all the advice and pointers......I'm gonna burn the stump that got the blade.....Isn't that how they do it DC.........they always have somebody else to blame for their screwups....;-)

Bought 3 cherry push mowers from this very thing. Mower doesn't cut well....... One was a virgin Commercial Snapper pusher looked brand new. Blade on upside down LOL. Paid a whopping 80 bucks for that machine. Big Kawasaki FJ180V engine too. Swear it had break in oil inside her.
