Bourgault 3710 or 3720 disk drill scraper mounts with studs. I have 36 right hand 36 left hand scraper mounts with studs installed and good rubber puck spacers. The carbide scrapers are at the end of their life. But if you have the old style mounts with the plow bolts and worn rubber pucks this would be an upgrade to the stud style mount.

Enough here for 60 10 space drill
