How to operate a MF 18 box blade

[oosik]

I have a six foot Bush Hog roll over box blade. I pull the trip lever - this lowers the rippers down onto the ground. To get them fully extended - back the tractor up - half a foot or so. They will rotate into the full down position and lock. Pull on the trip lever - the rippers will unlock - raise and lock in the fully up position.

I recently purchased a MF box blade and was scratching my head trying to figure out how to lower the scarifier bar. I found this thread very helpful and, not being very tech savvy, was wondering how to DM another member about the manual for this attachment. I am also wondering if anyone knows where to purchase new, or used, scarifiers. The slots are 3/4 x 2 1/2. I believe the bar requires the slotted version with the use of the locking bar. If I measured correctly the spacing between notches is 5” center to center. I scoured the internet but I couldn’t find anything with this spacing. Any help would be greatly appreciated!

I have a Massey 18 box blade. Both notches of the scarifier do not need to engage the beam. Only the top knotch needs to fit the beam. They are held in with a bar that holds spacers. I had fabricate one. I copied Degolyerent's one.

I bought the Gill box scraper w/ rollover scarifiers, hinged back blade. It's a load!

This thing is built like a Sherman tank! Everything seems to work as it should. Besides a new steel rod for the handle and a 1" 1/4 pin that holds the scarifir bar to the box (and paint) its a perfect unmolested piece of art. Once I buy scarifirs it won't be quick hitch compatible. The...

The scarifiers I used are 17-1/2 INCH BOX BLADE SHANK WITH POINT - NOTCHED ON FRONT

The box blade was made by Gill for Massey Ferguson. Gill is now owned by Woods.

Thank you for the information. I will be ordering some new shanks and flat pins so I can put this beast to work.

@orangeiron Your Massey 18 box blade sure looks better than mine! They are far from quick hitch compatible. Stand clear when lowing the scarifiers it is dangerous how fast they swing down.

Thanks for that info. I was wondering who the original manufacturer was. Good to know.

3yo old post here, but I just DM'd the original poster, as I had the exact same problem with my 7ft MF 18 scraper. And for 3-4 years I couldn't find any answers either. The correct answer is amazingly and stupidly simple. So for anyone else that might have been similarly and possibly embarrassingly mystified, here is how it works and what I sent to ALLDodge.

Greetings, I had the exact same issue, and found your post online probably a year ago, but you didn't get any correct answers. I saw it again today, and thought I'd reach out, in case you were still struggling. We found a workaround way to fully lower and lock the scarifier bar. It worked but it was far more work and difficult than it should have been. We'd lower the scraper onto 2 cinder blocks, and then wrestle the bar into position, but I knew we were probably doing something wrong. It shouldn't be that difficult. The intended method is of course ridiculously simple and "effortless" according to the manual I just found. With scraper on the ground, lower (rotate) the scarifier bar with the trip lever, then reverse your tractor a few inches, the scarifiers will latch into lowered position. That simple LOL!

The manual also solved another mystery on the center pipe and spring pin over the blade. Hope this helps hit me with a DM if you want copies of manual.

Hello. I have this same MF18 box blade and was wondering if you could email me the manual please? My email is danogh1959@ gmail.com. I’m trying to figure out the center pipe and spring pin function and to this point I’m mystified!

Thank You
