Don't buy these disc blades (pics)

jon f mn · Apr 16, 2013

My friend Jeff bought a case 2394 last year and needed a better disc. I found this one online in kansas. It looked great in the pics. You could still see the edge on the blades. I drove down to Ks to get it and the blades all looked good with just one broken blade. We used it on about 120 acres going over some more than once so it may have had 300 acres total use. The last field we had to dig out the old Oliver 12 ft and case 14 ft cultivator to finnish. The blades say "Tuff Edge" on them. We do have rocks but I've never seen anything like this before.

Rocks! Looks like You let er roll down the side of the Grand Canyon. I wonder how much the last guy paid for those blades. They maybe Tough Edge; but really soft centered. I hope all that broken metal doesn't cause a problem later!

RGMartin · Apr 16, 2013

Wow, I was upset when I had one new blade break in 100 acres or so. Still enough to really PO me as it was the one farthest from the nut. On it you can see where 2 coils of steel were seamed. These were heavy Brazilian made blades(5.5mm)

I have never seen anything like what you have. Any more info on the blades? I hope you don't find a chunk of them with a tire.

That is the only name on the blades. There was also
a pat. no. on them, but that was all.

WGM · Apr 16, 2013

Instead of complaining about broken disc blades why don't you pick up the rocks?

jon f mn · Apr 16, 2013

Good question. I'll ask Jeff why he is so lazy.

Russ from MN · Apr 16, 2013

Looks like chinaloy! Now he needs a metal detector.

Rick Kr · Apr 16, 2013

By the looks of the pictures the ground is still frozen, that is really hard on those blades, probably why the broke

On a serious note, in my 15 years of discing I have only broke two blades. The one I heard it right when it happened, big rock caught it perfect in the center.

Had another thought, how fast was he going? Just because a 2394 will pull that disc in 4th range doesn't mean you should. I had a flashback to my youth with a tractor much to big for the implements on hand.

jon f mn · Apr 16, 2013

You are right the 23 played with it. I did most of
the discing and went in 3rd gear 4th on powershift
and ran the engine slow about 1800 rpms. Worked
great and didn't burn much fuel either.

Jon, was the disc running level? and it may have been run nose heavy before you found it, I have seen blades break also due to the gangs not being tight, when the first one broke did you tighten it up? just a thought cnt

Wgm, I have been picking rocks in the same fields for over forty years and there are just as many today as there were 40 years ago. The frost will heave them up. If you use a sub soiler get ready to pick more rocks. We have alot of stone walls in North East, PA Maybe MN is the same, I just don't know.
I'm not being critical. Some areas of the county don't have rocks.

jon f mn · Apr 16, 2013

Tom, it was all tight and level. I have never seen anything like this. We do have rocks but if you buy good blades they will last 10 years.

Case Nutty 1660 · Apr 16, 2013

like the others said "Cheap Cheap" lol

Case Nutty 1660 · Apr 16, 2013

forgot to add I put a new set on my Case offset a few years ago bought them thru my Case dealer think they say "Earth Steel" on them seem to be dang tough blades I have lots of rocks also, they were not Cheap to buy though but with the work it was to change them it was worth every penny

Wheat Farmer · Apr 16, 2013

You said "You could still see the edge on the blades". Had they just sharpen the blades? Maybe got them to hot. Did you do a lot of turning with the disk still deep in the ground.

fixerupper · Apr 16, 2013

It doesn't matter if it's level or not, that's totally unacceptable. I wasn't aware that you could buy blades even close to being that brittle. Looks like the fronts fared better than the rears or is the picture deceiving me? Usually the front ones go first. I've had the disk bounce fairly high out of the ground when one blade went over a big rock and the blade didn't break. Not only do you have to spend bucks replacing blades, you have a field full of hardware waiting to slash a tire. The tire could cost more than the blades. Jim

A friend works for the Case IH dealer and sold me 40 22" 8ga. blades for $500. Dealer thru them in the dumpster because they weren't moving. He picked them out, I bought them.

jon f mn · Apr 16, 2013

Now that was a bargain. They would be near $40.00 a piece.

T in NE · Apr 16, 2013

We farmed a couple gravel pits from when they built I-79. My aunt drove the tractor one day picking rocks, in an hour she moved about 20 feet and went home.

I don"t miss rocks. At least, not til the driveway gets muddy.

CenTex Farmall · Apr 16, 2013

A farmer I know had a rash of broken discs after having them sharpened by a technique where they roll the edge back to sharp (as opposed to grinding). I forget the technical name for the procedure. They either did it wrong or the blades didn't take it well and he had cracking and breakage.

onefarmer · Apr 16, 2013

My farm has been in the family for over 100 years and rock picked annually. After 127 years there is still rocks out there.

JerryS · Apr 16, 2013

Burnishing?

JMS/.MN · Apr 17, 2013

UN-freaking believable! No wonder I"m a fan of field cultivators with rear tine harrows!!! Newbies here think they need an 8N, plow, and disk. Why? disks pack the ground, FC digs it up. Sure, for years I had a medium disk to cut plowed sod, but real field work was done with the FC. Now I have a heavy plowing disk....14 foot cut behind 190 hp MFWD, Springtime, cuts 8 inches deep in fall chiseled ground and destroys undergrowth in rough ground. That"s primary tillage. I"ve never seen a disk like yours, so broken up!

Patent number can be looked up, to find manufacturer. Try "Google Patents, or "Google"
for U.S. Patent office website.

OK, I won't.....

BDT in Minnesota · Apr 17, 2013

Jon; that disc looks like it fell off the truck, while going over an overpass at 70mph.

Bummer that all that scrap is in the field awaiting the tractor tires.... I agree with Russ ;another vote for the metal detector..

Clodbuster · Apr 18, 2013

It's called "disk rolling" and is common in the midwest. They have a machine with rollers that pinch the edge of the blade as it turns it to work the metal to a sharper edge. Main selling point is that they don't remove any metal from the blade like a grinder would.

It works very well but maybe that operator made the edge too thin and sharp or had metal that was too brittle.
