John Deere's 637 tandem disks provide optimum performance in a wide range of tillage conditions. The lineup includes the Regular Disk, the RockDisk and the Wheatland Disk.

The disks retain the performance features of the company's previous 600 Series disks. These include heavy-duty, welded frames; maintenance-free wheel module bearings; combination rigid/self-adjusting scrapers; and single-point depth control.

They're available in rigid and flex-fold configurations, and in widths up to 37'10".
