box blade use

wbond · Jun 13, 2014

I just bought a jd 770 with a front end loader and a 4' box scraper. after about 40 hours on I realize that this machine could do a lot more work if I knew how to use it properly. I have asked the dealer to come out but he is pretty busy and it would be nice to get as much info from as many sources as possible. What I mainly need help with is:
how to set up the adjustable lift arm
how to adjust the 3rd arm
ripper teeth
just as much info as I can get

The job I am trying to do at the time is moving very rocky dirt and making a level building spot and then cutting the steepness of a slope at another location.

Thanks for your assistance

Check out "How to Use a Box Blade" by Everything Attachment
on Youtube. It is a 9 minute demo on box blade use. There are some other good ones out there too. I hope this is some help to you.

As you can see from the video, the top link adjustment and the box blade's front-to-back tilt is the big secret.

Short top link, blade tilted forward means more cutting.

Long top link, blade tilted to the rear means less cutting, more smoothing.

Tilting left-to-right by lengthening one lift arm adjuster will give you a way to ditch, or with a less aggressive tilt, put a crown in a driveway.

It is really, REALLY handy to have a hydraulic top link so you can adjust the cut angle on the fly. It's nice to be able to tweak the amount of cut while pulling instead of hopping on and off the tractor a dozen times trying to get it right.

If you do much box blade work at all, the expense of a hydraulic top link is well worth it.
