does your box scraper not have holders for diggers and they are just missing in action?
note: they can fall out in rough hard gravel, if you do not have them pined properly.
i can adjust the diggers on my box blade up/down and then tilt the box blade forward, it will really dig.
Loosen up the soil or gravel, etc: then its much easier to level.
do not know what to say, i would want a box blade with diggers, if it was me.
can you buy one with diggers (used) then sell your old one, it would not bite so bad.
again i would want diggers, Just my two cents worth!!!!!
i also have a scraper blade, do not use it so much now that i have the box blade,
this year i also bought a rock rake,
each tool has its place and does a good job.
