Accurate depth control. Single-point depth control is standard on folding 637 Disks, allowing you to easily and precisely set depth from one point at the front of the disk. Mechanical stops are standard on rigid models. Double-action leveling increases stability. Double-action leveling also improves the disk's stability when you add rear attachments.
Tapered blades smooth out soil.
A one-blade taper plus an integral furrow filler is standard on the 637 Disk. They smooth out soil and reduce outside ridges for an exceptionally smooth soil profile. A finishing blade is optional. Farm service tires improve performance. Farm service tires provide a wider ground profile to distribute weight more evenly.
