Another dual blade grader idea....

[montejw]

I've already spent the money on a box blade, now I figure I really need(ed) a dual blade grader. With the box blade it seems like I've already got most of the pieces needed to build a dual blade unit, 2 blades, 3 point hitch and structure, 2 box sides. Just need to lengthen the sides, add bottom runners, and move the blades. Right?

Sounds doable monte.
There were some threads about home made jobs about a year ago or so. Do a search and see what you come up with.

I've seen a few of the built from scratch dbg's, haven't found a stretched box blade one though.

the comercial version is called Grademaster.

seems simple enough to build...

Not sure if this is what you are looking for but here is one approach I saw here on TBN...sorry I forget the original poster so cannot credit him.

You could add some guage wheels to the BB and just make two passes.

Yeah, I've seen those and the Dura-Graders. More money than I want to spend right now. Trying to figure if it's worth modifying my BB since it's here and paid for.

I've seen another like that. I haven't gotten into adding additional hydraulic circuits yet. Those look like they'd work pretty well.

That's another approach I suppose. The dual blade units look a little simplier though. But then again, maybe I'm being simple.

Check out these blades. This company has definitely done their homework. Probably one of the best designs I've seen. Roadrunner Construction Equipment - Out Performs Complex Motor Graders on Many Applications.

Those graders seem awesome! Any ideas on prices?

With the specs, it should be pretty simple to duplicate. Does anybody have one?

The name on the stone marker in the 4th picture says Trumpp.

Monte,

Reading these threads, if one already has the box blade, it would be pretty simple to mount a 2nd blade near the front of the side panels, at an angle. It could bolt on to the side panels for easy removal for normal box blade use. If I were doing it, I'd get some 3x5 angle iron, weld some plates on the end, drill holes through the end plates of both, and bolt it on. A cutting edge could then be bolted to the angle, as in the other posts.

I suspect gage wheels would add more benefit--and I'd likely do that prior to adding a 2nd blade.

But I'd not want to cut up my good box blade to make something new........

Hope this helps.

I've seen the Grademaster in use and it's pretty impressive. Nothing like a boxblade, and probably nothing that you can use in a boxblade to make one. Two different animals that have completely different designs. Trying to convert the boxblade sounds like a loosing battle.

I'd sell the box blade and buy the steel to build the Grademaster properly and not waster your time doing a half way type job.

Another company to look at for ideas is Roadrunner Construction Equipment - Out Performs Complex Motor Graders on Many Applications. They have a video that they will send you if you fill out the form. I haven't, but it might be worthwhile for you.

Good luck,
Eddie

Seems to me like there's quite a bit useful in a box blade that's useful. 3PH structure, 2 "blades", and the sides that can be extended with a little more material. Guess it depends on how much the steel would cost for a grader from scratch and the resale value of my box blade. Haven't researched either one.

I think I ordered a video from one of the grader manufacturers. I hope to see the difference it makes installing the blades straight across, or angled.
