Allen I have a few questions??? Why did you have to drill any holes??? I have switched 5 or 6 Oliver/White plows from one width to another and it was just moving things to the correct bolt holes that where already in the plow beam. In you first posting before you had done anything you showed the top of the beam and it had the three sets of holes that usually adjusted them from 14,16,18 inches.
Also on the regular plows I adjusted you left the front plow bottom alone and moved each one back closer. It looks like you did it the other way. Is this because it is a roll over plow? or did you go the wrong way???
Maybe Delta Red can answer me as he has had roll over plows for years. I always wanted one but they are not very common around here.
One local dealer did have a fully mounted six bottom roll over. He got it in a dealer close out deal and had to take all the new equipment the other dealer had. We never did figure out what kind of tractor would pick it up. We tried a White 2-180/MFWD with a full set of front end weights and it would stand straight up. He finally just used all the bottom parts off of it a scraped the rest of it.
