Box Scraper Box Blade Brace arms bent

[Sniggle]

Just a comment, as my Woods 60 inch box blade just got delivered....where the KK box blade has bent strip steel as arms the Woods BB has welded, bent steel plate...I see no way I could bend the arms on the Woods BB without taking out my tractor.

For my uses the robust Woods may be overkill, but I do not think that bent support arms will ever be a concern.

Hookblock, I picked up six 40lb front suitcase weights at an auction for $50 and they sit perfectly on the sideplates of my 60" KK box blade.

I've snagged roots with the rippers before that stopped my tractor dead in it's tracks and the frontier box blade didn't even blink but the lift arms have two plates with the pin set between them so the pulling forces are equal. I never was/is a fan of the lift pin supported on one end only. I bet simply adding another bracket on the other side of the pin will eliminate the bent bracket problem entirely but you might need to gusset up other parts of the box blade to strengthen it further.

Thanks for the ideas,and pictures. I got a used 72'' king kutter box blade that was damaged, I wish I would have taken before pictures. The same problem the first owner hooked a stump, bent it up pretty bad. A good deal for me, a few hours of straitening and welding good as new. The thing that surprised me was the quality of the welding, not that good. The box that holds the scarfire teeth is two angle irons welded together, I believe 4'' by 4'' by 1/4''. The weld on the bottom of that tube was on one side only, it didn't fuse the two edges together. And where the tooth hooked the stump it pulled the two apart, and put a kink in the one angle iron.

Again, I go back to the lift pin being supported on one side only. If the box blade gets caught, the pin being pulled by the tractor is going to want to TWIST in towards the tractor. If it was supported on both sides, it likely won't go anywhere. However, the BB depicted in the images looks to be made out of fairly thin metal. Retrofitting it by strengthening that area will only make the weak link another area of the BB, probably the square channel that is weakly welded. Weighing the box blade down will only increase the stresses that the BB will see but if you want to do it, my vote also goes towards installing suitcase weights to hang on the side plates or the lift/brace/pull arms.

Here is an image of my lift arms and how I weighed down my BB.

TOMK, I noticed the grab hooks on the back of your BB. What do you use them for?? I'm always interested in expanding capabilities of equipment.

I used them for pulling a chainlink gate weighted down with some 6x6's as prep for seeding a lawn. I was also able to use them to pull my daughters car up our snowy driveway once. I'd be afraid to use them with too much weight.

The suitcase weights are definitely a better way to go. I used the pipe and weight method because it was a quick and dirty way to go and I had the materials available.

As far as weights go, I was able to get my hands on some scrap train rail and a 4 foot piece on my 4 foot box made a world of difference. If anyone has not tried putting some extra weight on, you should try .... it is amazing how much of a difference it makes.
