Designed for deep vertical tillage, the Great Plains Inline Sub-Soiler shatters yield-robbing compaction layers created by horizontal tillage tools such as plows, disks, and sweep implements. With a working depth of 10" to 16", this fall tillage tool resets the soil profile and maintains uniform soil density with minimal topsoil disturbance and no residue burial.
The Sub-Soiler’s frame features high-tensile, 3/8" wall tubing for added strength and durability. Units are available in 24", 30", 36", 38", or 40" shank spacings. Shanks range in number from 3 on 30", 36", 38", and 40" spacing up to 12 on 24" spacing. Choose from two shank options: ¾" and 1¼". The ¾" no-till shank and no-till point provide maximum shatter with minimum surface disturbance. The 1¼" straight leg shank creates more surface disturbance for minimum tillage. To achieve the full benefits of vertical tillage, it is important to select a point design that promotes horizontal fracture without blowout. The Sub-Soiler is offered with several different point options to fit a variety of conditions and needs. - Less

CHOOSE POINT STYLE
The 1¼" straight-legged shank is available with points in 2" or 7" widths. These can be ordered with or without fins (fins minimize blowout). The ¾" no-till shank is only available with a 10" no-till point that minimizes surface disturbance and residue burial while maximizing soil-structure-shatter below. New for 2022, all shank points and shins will be manufactured from chrome alloy – substantially extending the wear life of the points. Plus, a new 4" no-till point is available for 24" shank spacing.
CHOOSE SHANK STYLE
Choose a 1¼" straight-legged shank or a 3/4" no-till shank. The no-till shank is not as aggressive as the straight-legged shank in turning the soil over and covering residue, so it should be used where less ground disturbance is desired. Replaceable wear shins are standard for either shank option.
20" HEAVY-DUTY UTILITY COULTERS
Large 20" utility coulters cut residue directly in front of the shanks. This allows it to pass by without catching the shanks.
CHOICE OF AUTO-RESET OR SHEAR BOLT SHANK MOUNTS
With 3,000 lb. trip force, the Auto-Reset Shanks provide stop-free operation in areas where sub-surface obstructions exist. Alternatively, the Shear Bolt Mounts provide obstruction protection at a lower purchase cost than the Auto-Reset Shanks. New for 2022 is an 1,800 lb. spring pack for enhanced performance in rocky conditions.
SHANK SPACING OPTIONS
Multiple shank spacings allow the Sub-Soiler to be tailored to your specific soil needs.
OPTIONAL INLINE HITCH
Economical tongue and hydraulic gauge wheel kit turns a 5-shank or smaller sub-soiler into a pull-type unit.
OPTIONAL BERM CONDITIONERS
With 1" solid rods, the 16"-diameter berm conditioners mounted to each shank help provide a level surface, enabling single-pass seedbed preparation.
OPTIONAL SUB-SOILER HITCH
Turn any sub-soiler into a pull-type unit, as well other 3-point implements.
