Thack: There is basically nothing wrong with any disks built by North American manufacturers of the 60s, 70s and 80s. Disk blades, arbors and bearings were probably all turned out in a couple of factories. The problem comes with dealers who speced them out and ordered light blades, purely to compete in the market place. I bought a new 12' Cockshutt disk in the 60s. to replace a 8' disk. In the 70s I bought two new Bush Hog disks, 20' tandem and 12' offset with 26" blades. Why did I not buy IH? Simply because the IH dealer destroyed IH disks in our area by bringing them in with light gauge blades. In another area it could have been another make. Every manufacturer had access to about 6 or 8 different gauge disk blades. You have to access every disk on it's own specs. The light gauge blades don't stand up very well, plus they don't have near the weight to make a good cutting disk. I really don't care what make the disk is, however if it's over 12' wide, be sure you have 1-1/4" to 1-1/2" arbors, spacers at least 6" diamater at back side of blade, tapered roller bearings and disk blades 1/4" to 3/8" thick at hub. That IH 37 could have been ordered with much lighter equipment. Every disk must be judged on it's own merrits, regardless of make.
