How to Remove STUCK Depth Adjuster Arms and Covers on John Deere 1890

Despite the title, this is a multi-day, on-farm rebuild log of a 30-foot John Deere 1890 drill, not a focused how-to on stuck depth adjuster arms alone. A crew tears down row units, torches off seized depth adjuster arms and covers, replaces seed boots, boot springs, closing arms, and hubs, and discusses bearing replacement decisions. Useful for 1890 drill owners tackling a full row-unit rebuild, less so for someone wanting just the stuck-arm removal step isolated.
