Corriher BoxBlade looses tooth!-Built-in Safety

<font color="blue">( They are designed to bend or break and not damage the mount. Scarifier shanks are not designed to dislodge large rocks. If you would have been plowing and hit rock like this, the plow would trip the safety release. ) </font>

I agree…

Hi Guys,

Just as grade’s 2 & 5 “shear bolts” shears on different PTO driven equipment as a Safety Device… so be it with these scarifier teeth/pins…

Notice the mfr. horsepower range design ratings on the implements… ex. buying a 40-75 hp boxblade and using it with a BX2200… (hypothetical if! /forums/images/graemlins/wink.gif) Don’t blame the implement mfr. if the tractor’s 3-pt hitch breaks/bends or something shatters on the tractor… because the implement was designed being “heavy/medium duty”…

Perhaps, “operator error” was not the proper wording, but I find it hard to believe anyone was trying to be mean as much as they may have been trying to be helpful… /forums/images/graemlins/shocked.gif

Believe it or not Guys… these mfrs. don’t want you tearing up your tractor or the implement… sometimes paying more for heavy duty will get you more than you inadvertently bargained for… /forums/images/graemlins/blush.gif

CCI,

There's no question you're threatened by Corriher's reputation and the competition that they offer.

That aside, where do you see that BobG admits to operator error ? I looked at his post and the words never appear.

As far as I know, there aren't too many people who can see underground and hitting something not seen is an accident not an ERROR.

BACK OFF !!

ps. add me to the 'never a customer' list !

I'm defending Corriher just as the John Miller says above. Neither the dealer or the MFG could be in the field to avoid the obstacle so the operator is the only one that has care, custody and control so it's the operators responsibility to avoid known and unknown obstacles. The box shank did not fail it did exactly what it was designed to do.

Hi,

I wonder how any of us can tell if the part failed properly, or because it was defective. Was it made in a country where the steel industry has very good quality control, or in an upcoming third world county where quality varies like the weather. I don't know. And neither does anyone else here who has not seen the broken part...

It does sound like that box blade is a heavy duty unit. Every thing can be broken...maybe the manufacturer will replace it anyway, can't hurt to ask.

For some reason I am having a problem with the "using a heavy implement could damage your tractor" thought. Or the fact that hitting a relatively small rock is likey to break a heavy duty box blade... Manufacturers know that rock are in the dirt. They almost certainly design for this fact. A football sized rock is not a big rock. I doubt that shank teeth should be breaking off every[or even any] time a rock that size is encountered.

Was "football sized" the term the original poster used? If so, who knows...maybe footballs grow bigger up his way... /forums/images/graemlins/grin.gif

As for damaging the tractor which John mentioned [I hope I am remembering right] by putting too big an implement on...Seems to me this should not happen if the implement is used properly. I mean pulling a box blade should not damage the tractor in my opinion. If the tractor is too small it should simply spin its tires or not be able to lift the implement. The beauty of hydraulics at work. You just run out of umph before you break something.

Oh the other hand, there could be exceptions. Like if you were carrying the max weight possible in the transport position, and dropped into a hole or hit a curb at speed, the shock load could damage something...

Same with the loader...should I expect it to break because i grabbed a root and stalled it when trying to lift? Don't think so...it should just stop going up and the pressure relief valve should kick in.

Now pushing backwards on the 3ph linkage with the box blade...well, that might cause damage since the 3ph is designed for pulling [tension] not pushing [compression].

If I hook a chain to my draw bar, and try to pull a stump out should I worry about damaging the tractor when the stump does not move? I don't think so...

Somehow I can't believe that hooking a huge box blade to my little bx tractor would damage it. I do believe it would be useless to do that...wouldn't work. I probably could not lift it, the tires would probably spin if I tried to pull it, and if I had real good traction the engine would stall if I was so slow that I did not realize what was happening. But I don't think anything would break...

I guess if I subscribed to what CCI is saying I would be afraid to buy and use any implement because any time it failed it would be my fault, because I used the implement and did not avoid unknown obstacles that are expected to be found ,out of view, under the surface of the ground...

<font color="blue">The box shank did not fail it did exactly what it was designed to do. </font>

Respectfully, CCI neither you or I could make that statement with any certainty. You may be trying to stand by your original words...but in fact it might take a metalurgist to really give the accurate assesment. And he could not do that with the information we have at hand.

Using and abusing are not the same thing. And failure due to use is not the same as failure during abuse.

If the box blade manufacture designs his box blades so the teeth break off every time a rock that size is struck...well I would never try to defend him...I would be telling my friends to buy some else's box blades.

But I doubt that is the case here. Your point would be well taken if the rock in question was a bigger one than the original poster indicated...And/Or if the box blade was not sized right for the tractor it was used on. That doesn't seem to be the case here.

There are 4 different Indian scarifier MFG in India. The all purchase the same steel. I know the MFG of the tooth in question. The shanks are designed to bend or break at 1200-1400 NM of force. The size of the rock is not as important as the compaction of the soil. If the rock is in lose loam soil and not clay it will take less force to move the rock out of the path of the shank. Also the depth & speed at which the shank contacted the rock.
Just yesterday a customer burned a PTO clutch out on his New baler because he ran a fence post in his baler. He asked for warranty. I told him that Vermeer would not cover that but as a dealer I would supply him the parts free of charge if he would do the labor. About $50 worth of parts and the customer realizes that CCM warranties this not Vermeer. I had a customer turn his tractor and baler over and asked for warranty on the baler. We told him we would charge him the our cost on parts and do the labor for nothing. The labor alone was 40+ hours. A warranty is financial protection for the dealer not the customer. Dealers that stay around are about customer satisfaction and education. A customer this year purchased a seat and destroyed the seat because he did not realize the way he mounted it allowed the three point hitch to contact the seat. He sent it back and we refunded 100% of the purchase price. We always are up front with the customer if you are unsatisfied with a purchase well purchase it back or replace it. When you tell a customer this the customer knows they have some responsibility. The funniest one I can remember is a woman with horses purchased a used round baler and baled he first cutting and asked for money back because the baler created too much dust, she had a cab tractor. LOL We gave refunded her money and resold the baler for more money so all parties are happy. Corriher will likely send a new shank just for customer relations. There are times to ask a dealer for help when you really need it and times that you need to pay for a $5 part.
John Miller is correct that a customer needs to match a the implement to the tractor. I had a customer this year that put a SR210 tiller on a Branson 3510. The customer hooked a root it reared the tractor up and he fell off the seat on the ground. The recommended HP range for this tiller is 60-100HP and the Branson 3510 has 31 PTO HP. Thank goodness the customer was not hurt, only his pride. You just have to mother and educate every customer because you just do not know how much judgment and experience a customer has.

I think that its a good thing that the tooth broke! If it hadnt, then just imagine the real damage you could have done. Now its only gonna cost you 15 dollars. Not even worth worrying about. But if it had not broken, it could have seriously damaged the whole box, or even worse, your hitch. If I hit a huge rock with my rotary cutter (or any other implement for that matter) and it breaks, im sure not going to blame the manufacturer. However I would probably be praising their product if I jumped off the tractor, and inspected the damage only to find out that a shear bolt or a tooth broke as opposed to tearing my tph all to hell. Just my opinion. /forums/images/graemlins/grin.gif

For the record: the Corriher 30 Series 7ft box blade weighs in at a mere 700 or so lbs. and requires a minimum of 40 HP. My "little" tractor weighs in at approx 8500lbs (w/FEL and loaded 16.9X28 rears), 60HP. I was in 2Low just above an idle when the tooth broke off. The advertisement on the box blade said "for extreme duty" (See Corriher add on ebay for 1/2in sideplate models). Again, I'm not a novice with a garden tractor here. Ground was not hard packed but was piled approx one year earlier after a house foundation was dug. And yes, the rock didn't weigh more than 25 lbs. I guess if I told you what brand of motorcycle I ride, CCM would probably have some smart remark about that too.....

There are just too many variables remaining in this equation. How deep were the teeth being run; what was the actual compaction of the soil (in my area, this type of excavated spoil would have turned to a concrete-like mass by this time of year!); was there a flaw in the casting of the tooth; was the tooth assembled correctly at the factory? Based on the facts presented, none of us have the information or knowledge to ascertain exactly what caused the problem.

While I am sympathetic to Bob and his troubles, he needs to address the issue with Corriher directly and not debate it in this forum. If the problem is not resolved, then complain.

As for CCM (Mark), while I do not know the man personally, I will state that he is of what I would call 'high character'. A couple of weeks ago I tried to purchase a Midwest box blade through CCM. Mark spent quite a bit of time with me while digging up the name and toll-free number of a competitor closer to me so I would not have to pay as much in freight. He gave away a sale, but gained respect. I do think however, that his initial response to Bob's situation could have been a bit more 'diplomatic'???

My God, I am starting to sound like a peacemaker! Time to get back to the shop and reality. . . .
