Box Scraper United 672 box scraper blades

bryn60 · Sep 5, 2016

Hi can anyone please tell me what the angle of the forward and reverse blades are on my United 672 box scraper in relation to the box and also are they both touching the ground together assuming that the box is level.I ask these questions because I purchased a second hand unit and found that the rear blade touches the ground first which brings me to the believe that the blade mounting assembly is at the wrong angle.Thanks.

A friend has one I just looked at. The rear blade contacts first and is lower probably 1.25 inches at the cutting edge. Front blade is about 35 degrees and rear slightly shallower maybe 28. This one has quite a bit of wear on cutting edges that yours may not.
Hope that helps.
