Vendor Listings
A large variety of equipment is available for subsoiling. Some subsoilers are mounted to tractors with a three-point hitch; others are wheel mounted and pulled with a drawbar. Subsoilers designed for agricultural use may be suitable for rangeland, but they may be too wide and not sturdy enough for forested areas. The market for subsoilers designed specifically for forestry applications is limited.
Manufacturers have designed and operated rippers with vibrating shanks, but they are used mostly for trench ripping when laying cables. A new design from Soilworks California incorporates a vibrating wing that moves up and down as the shank is pulled through the soil (figure 11). Designs and options change often and can be customized. Call the manufacturer for the latest updates and options. A partial list of subsoiler and shank point vendors follows.

mounted behind the shank.
