Death of a BoxBlade

[JohnS]

Mark, Heck of a little rock that you decided to pick a fight with! /forums/images/graemlins/wink.gif Having a heavier duty boxblade might have prevented it, or possibly caused some problems to your tractor. While there was little to no chance of moving that boulder, hopefully the tractor would have sat there and spun the wheels. The next weakest link might have been the Jinma 3pt arms. While the Jinma 3pt is cat1, comparing to other tractors, they don't seem as heavly built. Maybe thats a good thing. If they were over built, the next weakest link could be very costly.

How does the XB line compare to the standard KK stuff? The arms that bent don't look much different, and didn't see specs for XB on their website. Just curious, since I have the standard light duty 5' KK boxblade. I do believe you are correct on the operation, while they have a rear facing blade, it is mainly just for smoothing out loose dirt.

That was obviously from pushing the blade in reverse. I don't think any of them are designed to withstand a lot of abuse going backward.

I just received an XB middle buster/sub-soiler. I am very disappointed in the quality of the product, especially the finish. The paint job is terrible. There are heavy runs in the paint and places where the paint is peeling (at weld joints); many chips/gouges in the paint. Some of the weld joints look like they were welded by me and I have never welded anything before. I talked with the dealer about it and he did offer to take the unit back but I decided to keep it. I sent a letter to KK customer service but I never heard back from them. Don’t think I will be buying any more KK XB product.

It could be worse. At least the 3 pt hitch componets stayed intact. Rat...

I use a Gannon and a Gearmore in reverse constantly and without concern. There is no way they will break from using reverse. The blades are replaceable in reverse direction as well, they are designed for it, well at least some of them. Rat...

It doesn't appear to me that the design and angle of the lower lift arms and other 3ph parts is meant for pushing an implement to any great degree.

I don't know how to answer that since I'm not sure which tractors set of 3 pt componets your talking about. Mine could easily push or pull anything the tractor dishes out. Considering the relatively low amount of leverage placed to the 3 pt hitch versus a loader, I can easily control and cut in reverse with my boxblade over my loader and seemingly with less wear and tear. This is not true of the NH 2120 we use as the lower links are not strong enough for even a medium duty box blade in forward much less reverse. I'm sure it depends on the manufactuer. Rat...

In the picture showing the lift arms, they're raised so that the blade is off of the ground. When blading (and undamaged) the arms are parallel to the ground.

Pushing I think started the damage by bending the pivots on the blade outward. Once the bending started things happened in a span of 2 feet.

I Don't think I was moving at more than 1' per second. The rock was at ground level when the whole thing started and I was probalby cutting 6" of dirt off of the top.

Mark, your boxblade is definitely built to lighter duty standards and is obviously the reason the for the domino effect. If you look at the picture I posted in your post, you will see how the more heavy duty boxes are built. Even with the sides bending in at almost a 45 degree angle, the mounts still stayed straight and true. On my boxblade, it would be almost impossible to bend the mounts as happened to yours. When I catch a rock or other unmovable object, my tractor comes to a stop quickly. It happens routinely going in reverse and in forward with the rippers down. If you replace your boxblade, check out the models by Woods at woodsonline.com. Rat...
