Breaking up compaction layers to provide uniform soil density with minimal topsoil disturbance and residue burial, Great Plains’ sub-soiler has become a become vertical tillage tool.
The VT1500 is available in rigid and folding configurations, and the configuration can be customized for shank spacing, shank styles, mounts and points. Shank styles include 1¼" straight-legged shank with or without fins as well as 3/4" no-till shanks.
For extended life all point and shin options are manufactured from a hardened chrome alloy.
The new VT1500 Sub-Soiler is built for longevity particularly in no-till and rocky applications. For example, the VT1500 Sub-Soiler is now available with new high-protection trip pack auto-reset shanks, so the shank mount trips at 2,000 lb. or is also available with 3,000 lb of trip force. For lighter soil conditions, a shear-bolt mount option is available.
In the product release, Blake Bergkamp, Great Plains Sales Agronomist, said, “We have seen some significant wear life improvement with the new chrome alloy points and shins. We worked with a customer from the Texas Panhandle who grew irrigated corn and triticale in some pretty sandy conditions. After switching to the new chrome alloy points, this producer now has over 1,700 acres on the chrome alloy points and shins. As a comparison, he replaced one shank with a standard shank, and it wore out after 400 acres; in this case, these new points and shins had over four times the wear life.”
