bush hog box scaper? look again

[Scratchnbell]

I recently purchased ( a week ago)a bush hog box blade from my dealer.
I noticed that the rippers didn't hag down past the blade on the middle setting. Went back today to check it out.
On every other brand on the lot the bottom hole lifted them out of the way, the middle hole was slightly past the bottom of the scraper and the top hole put the shanks down past a good deal.
The salesman called bush hog and said to look at the otehr s and if they were the same that is just the way it is. I wish I woulds have seen this before, i would have bought another brand. I still think that bush hog maybe messed up a batch of rippers or put the wrong rippers in the wrong size box scraper.

Do you have to incorporate the length of the top link into the 'design' to get the rippers to function right when set in the middle position?

Are you talking about when the box is level or fully in with either the top link screwed as short as possible or with the hydraulic top link shortend? If it won't get into the ground that way, they may well be either the wrong ones or inadequate. My rippers (hydraulic) have only two notches. I always run them fully extended.

I used the 72" for a good while, and noticed that the rippers dragged just a tad even in the full up position, depending on my top link.

I have a 48" which is pretty much as you describe but I find that it works fine, while doesn't "look" like I would have thought. My shanks are 3-hole x 16" long. When the box is set to level, I have found it really only needs to penetrate the ground by a half inch or so to fill it quickly, which is a pretty good load for my baby tractor. The box sides are chamfered at the front which does allow for a really aggressive cut with the top link shortened up ... as has already been said. That being said, I wanted to use my BB to do ripping/scarifying without dragging any material which it was not capable of doing. So, I bought 4-hole x 18" shanks from Agri Supply for $15 ea. Now I can shorten the top link and extend the shanks all the way to do some ripping about 2" deep with the blade a few inches off the ground. Hope that helps.
Cheers neighbor!

About a month or so ago I did a photo comparision of different brands of box blades, I don't think there were any Bush Hog brand blades in the comparison. What I know about the 2 brands I use is that in the mid-position, the scarifier teeth will be slightly below the blade, when the box is held level. So having the scarifiers in the middle hole is essentially ripping at a very shallow depth. The top hole lowers them to deep ripping, the bottom hole raises them above the level of the rear blade.

Here is a link to the Box Blade thread: Photo Comparision :: BOX BLADES It would be interesting if you would take photos of your blade and add them to the Photo Comparision thread.

Bob, I read that post with great interest as I was in the market for a new box blade.
Even my $400 chineese blade has rippers that extend up and down like they should.
After spending almost 800 for new blade I don't think I should have to go to buy new rippers.

Although not specifically mentioned, I will assume you referred to my post in your reply to Bob as having recommended that you should buy new rippers. If that is not the case, please ignore the following: I bought new rippers to perform a specific, "non-intended", purpose of ripping without dragging the ripped material. To be more specific, I find my Bush Hog SBX 480 to be perfectly designed and manufactured for the purpose intended. Furthermore, I find the shallow penetration of the [factory] rippers (~1") to be more than enough to fill the box in short order in bullet-proof clay soil. Note, that it is way too aggressive, and must be backed off, with just a minimal amount of moisture in the soil.
