Box Scraper What to look for in a BB scraper

[jenkinsph]

I have a Cammond boxblade for my mower that is well built and available in 48,54 and 60" widths IIRC. I bought the 48" model but I looked at the 60" and it is very similar just wider.

That Cammond is about the weakest looking BB I have ever seen. Absolutely no bracing between the front pull point and back blade other than the side plates. Not even a cross brace from the 3 PH to the back. I have a HOWSE heavy duty model about 3 years old and I pull it with my 70HP tractor. Weakest link is the scarifier teeth which bend and break when hitting immovable objects like large rocks similar to one in my Avatar. I have broken 3 teeth on it and bent them a bunch of times that were able to straighten back. It also has 2 bars welded between the front support for the scarifiers and the back blade to tie the front and back together.

That Cammond has some nice features for that size. The lower links, where the most force is applied, are clevis-type.

It is doubtful that the Cammond would be destroyed behind that tractor. Now, behind a 70hp it may be a different story.

Gary,
Here's a couple more pics showing the structure of the blade assembly, this is what keeps the blades ridgid. A brace across the top of the box does little to prevent putting a bow or kink in the blades below. The top link mounting has to balance out the rotational forces about the 4x4" boxtubing cross member caused by the rippers. The upper section is fairly thick steel and can handle more than the tractors top links can.

Notice on the Frontier (Gannon industrial) boxblade it is similarly built with no horizontal bracing to the rear of the box. This is a much better boxblade than a Howse in every way.

OK, since we are doing "Show & Tell" :

I figure if that design is good enough for the current J Deere 210 LJ landscape loader it is good enough for me.
My larger boxblade (yellow) is a Frontier BB1284 pictured above.


I should also note that the x749 and 2320 have the same engine and hp so that the Cammond pictured is a close match for these small machines.

I have the BB48 here is a link to the Cammond specs, note it is rated for 40 hp, well above the 24hp of the OP's 2320.

Thought I would bring this thread back to the top.:laughing:

Still think Gannon knows more about designing boxblades than Gary does.

Noooooooo, say it ain't so.
