Hydraulic scarifiers: various designs

[Xfaxman]

Several years ago I had a BB with rotating scarifiers, tried to use it in wet clay and when full, the dirt would stick to the raised scarifiers when you lifted the BB. Had to bounce it to get the dirt to fall out.

I have a Cammond 6' with manual straight up and down scarifiers. Their hydraulic version is the same layout.

Dozer mode.

Eric,
If you can find a good Gannon with the side plates worn down it would be easy to build them up. Don't need much more than a torch and cracker box welder to make this repair. It helps to splice the new metal on in a curved line as it will help with keeping the plate straight. Grind and smooth, repaint and you have a new box blade for cheap.

The two that I've seen were so worn that even the rear blades had been worn down. To retrofit as you suggest would require me getting a 4x8 sheet of 1/2 plate, firing up the Powermax 65 and plasma cutting out the sides, getting new front and rear blades, and welding it all in with the Millermatic 200. Too much horsing around, for me.

The bigger cammond units use the same style 4 bar linkage as gannon. I considered this line also but didn't find amy dealers locally . Tuffline doesn't appear to be mucheaper. I paid under $3200 for my gannon 88hsd at it has the added bonus of replaceable side plates

Cammond 4c5

Wow, that is a good price on the Gannon. FWIW, and I'm cheap and have shopped it, a Gannon high back HD80 (no tailgate) is coming in at $3200 from a little dealer 60 miles to my north. A 7' wide Cammond 4C5 (their heavy one with a tailgate) is at $3600 from my Massey dealer in Bemidji. One thing that hasn't been made clear to me is if either the Commond or Gannon tailgates can be locked down.

I've also been holding out for EA to offer something (as Travis and Ted have been super!), but I need the box blade before I can take delivery of a container this spring.

My Cammond can be locked just like the new one from EA, but only with two pins, one at each end.

Insert pin or bolt through the holes at both ends, to lock the tailgate. :thumbsup:

Eric I misspoke i have a sticky note with $3195 on my wall that said woods i thought that was the box scrapper it was obviously for something different possibly a brush bull . I looked at my receipt it was $3550 total for the hoses and fittings i was billed $3365 for the box scrapper alone.
So the tuffline is about 10% cheaper. I also liked the Cammond but the dealers were limited. I found the distributor in Michigan for tuffline and called them looking for a dealer they had tractor supply listed as the only one close. So i headed up there and immediately found they were not at all interested in ordering one of these for me. They had a couple decently built Tuffline 3pt disk at the store and i was impressed at how much better they appeared to be built than the County line or whatever their cheap line is.

I can see now in the last picture that the lower retainer will actually strip the clay off the shanks as its raised.

Good to know. Seems to me the owner of Command told me that too, I simply forgot to write it in my notes.

I may not have been clear enough about the repair. A piece of flat bar 1/2" x 6" x 6' would be plenty of steel to make the repair. I would lay the flat bar against the lower worn edge and trace the curve on the flat bar. Cut the flat bar to match and weld the addition on the side plate. I would not change out the entire side plate as there is no need for that. Grind the weld smooth and paint.
New bolt on blades for a Gannon cost about $25/foot, with bolts, flat bar for above total cost would be less than $450. If the Gannon used is cheap enough this might save you about 1/2 the cost of a new one.

Just to clarify my previous post, when the rippers were rotated up, they were still below the top of the box. So when filled, the wet clay would pack around and over the rippers. When you lifted the BB all of the clay would stay in the BB. Even what was under the rippers!

This is a better design, for the rotating style, the rippers come up higher, out of the box.
