The hydraulics raise and lower fine, I just needed the front weight to keep the front end down. that disc can almost plow a field. These discs were sold back in the 1970s and 1980s for big GTs like th eMassey 1855 and Bolens HT20, both of which had three points, they also made a bigger plow, and cultvator. The weights are on ebay from redlandhill which sells LOTS of great stuff for big GTSVery NICE massey! How well does the tandem disk work for you? Do the hydraulics handle the weight ok? Are those weights for sale to the general public?
