Using hydraulic scarifiers on a box blade without hooking it up.

Turns out it's actually a Cat I hitch and it hooked right up.
Thanks for encouraging me to take a look at it, folks, it's a beast and an incredible buy for the money. Ran it for about 30 minutes this morning, the CT235 pulls it just fine...i won't say effortlessly, but with the scarifiers up, the box can be full of material and it just drags away in Medium range...both on gravel and soil (so far). I'm sure it will be rougher with them down.
I might remove the cylinder and just hang a big handle off it ala rollover box blade. The cylinder doesn't provide any locking force, just up/down and there's a monster latch to keep it in place.

Looks like you got yourself one heck of a deal. :thumbsup: Now get that "TnT" and you can really do some grading.
Would you please post a pic of the latch. It just does not make any sense to me of having a latch with a hydraulic. Do you have to get off of the tractor and unlatch to then use the hydraulic to raise or lower the rippers?
:ashamed:

I don't understand it myself, actually, and I'm remoteless at the moment so i can't operate it at all (sans pulling the cylinder). There's a bit of a odd arrangement of pivots and springs involved, and my guess is that the springs hold the rack of tines in such a way as to keep the latch engaged. When the cylinder activates, it pushes aginst the springs to unlatch and then rotate the rack up out of the way...or something like that. It could be that the cylinder bears load in one direction and the latch in another, it's all too complicated for me to see.
1 is the main cylinder action, which pivots and causes 2 to pull front to back.
3 is the same as 2 above, and is some kind of buckling link arrangement that seems to cause both the rack to rotate and the latch to operate. I believe the horseshoe was added, as was the additional bit of steel in the center.
The latch is heavy duty.
Here are the springs, i can't tell exactly what they do, maybe provide a biasing force to cause the latch to operate before or after the rack...dunno. Can't wait to see it work.

The latch when down needs to be there to keep the pressure off of the hydraulic cylinder and seals. The scarifiers have tremendous force on them as they are dragged through the ground so need to be locked when down.
When the "up" hydraulics are activated the first movement causes the latch to unlatch and the hydraulics can then lift (or rotate) the scarifier mounting bar. It would be nice if there was a latch for the up position. My hydraulic cylinder leaks down over time.
Do you think it would be possible to create a lever to do the same...adding an up latch of course? I would think a good four or five foot lever should have enough oomph to rotate the scarifiers up. Only issue is making sure the things don't give way and you get hit in the back of the head with a 70mph crow bar.
Oh my! Look what the cat drug in...
First 'T' anyway. Now i just need my stinkin' remotes!

Since it appears there is no real pressure on the cylinder I think you can just go with plan A and just swap hoses with your HTL when you need to move the scarifiers. You could also get a manual or electric diverter valve to "split" your one remote into two.

My only concern would be "was the unit stolen "?
That boxblade appears to be a 7' Gannon rebadged for Deere, with 8 scarifier shanks should be the same as mine. New ones sell for about $3800 today and I can't see any appreciable wear on this one. The latching mechanism works well and you should be able to unplug the hoses in the down position.
These units are commonly sold on the rear of the 210LE landscape loader bet someone is missing theirs now.

It's definitely 72", but the scarifier clips, center post and rear hinge designs match yours exactly. As far as stolen, I don't know...kind of an unwieldy item to steal, but i guess it could happen. The guy that sold it didn't need the money, that's for sure. If i really got it for $.12 cents on the dollar, i'd say it's more likely a landscaping company went belly up and unloaded their equipment. Look at the 'fancy drill press' thread, that guy guy twice the deal i did.
That though's going to be stuck in my head now, though. Not sure how i could prove it one way or the other...call the police for stolen goods?
