KingKutter BoxBlade, Never Again...

Any time heat is applied to steel it weakens.

My BB is a no name but looks exactly like yours and what little I've done I've hooked some nice roots (living) and nice sized rocks and not a thing.

L1, that's slow enough.... I think you may have gotten a bad BB.

Ill agree with andy m you need to add steel to top front and rear bottom at the shank, also pulling down that hill gave the tractor an advantage on force applied to the box it wouldn't of had on the level.

All of my tines are bent a little like yours. I bought a used 5' KK boxblade for $100 so I can't complain 4 years (& 3 cleared acres) later with it still doing what I need it to. Your use looks similar to mine with all the tree roots that can really do a number on the tines...

Have you tried contacting KK and asking if they'd be interested in a failure? Often times they are interested and someone would come look at it. They may offer to replace or repair it, and I have had an implement rep provide materials for repair with the understanding that I would perform the labor (sort of a compromise). It would not hurt to try, before you start welding and cutting on it.

To answer everybody's questions...

Just pulling it along with the Jinma 224. Turfs, 4WD. I hadn't thought about the additional force applied by pulling down hill. I can see where that could apply additional force, but I can't remember it struggling to pull anything.

Fixing it will be easy, I'll just add a small section of 1/4" plate to the main support member in front of each tine on the top and on the bottom in the back. That will double the amount of metal supporting the tines.

My Landpride 8' boxblade is also somewhat torn in from of the tines. If you look at the design of most box blades, it doesn't take much to twist a tine socket out if you actually grab something hard. Just too mcuh leverage exerting all it's force on a couple of small spots. Most BoxBlades appear to have no reinforcement at this point.

it must be that *** china made tractor! everyone knows they can't pull anything and will break down first time you try to start it.! lol

Ya that hill I would say contrubuted to the blade ripper problem. probably found a nuther one of thos PEBBELS you have laying around up there! I used my 6' howes the past weekend to rip up old lake bottom. didn't catch anything but ran tiller through later and even at 8" depth wasn't picking up any rocks worth worrying about. still have afew to back hoe around and chain out though... I took a few pictures of my stream and have them posted here also some rocks posted here

Hi
I have a kk box blade and the part the tines go thru is a box looks like made from 1/2" steel. Is the part the tines fit into on yours open on the bottom? and how thick is the metal? I have had mine about 10 years, maybe they are making them out of thinner metal now. I have handle mine pretty rough used it to ram stumps and big rocks and it looks like it might out last me.

here is a couple of pics.

If it was a chinese Box Blade, it would weight 1200lbs. and be made of cast iron. /forums/images/graemlins/grin.gif

And I didn't hit a pebble this time. Granted there were a bunch of soccer ball sized rocks, but none of them halted the tractor one little bit.

I guess I'm just irritated that I have to spend a few hours fixing something that doesn't work as advertised..
