Wylie manufactures two styles of coulter applicators, a knife unit and an injection unit. Both units are mounted on a heavy duty double 4x4 toolbar and include a hitch for pulling a Hi-Rise trailer. Most coulter rigs use a ground drive John Blue metering pump for accurate applications. The coulter assembly is protected by poly springs and mounted on a 1x3 shank. The injection unit utilizes a 24" smooth coulter that slice a thin slot into which fertilizer is injected under high pressure into the ground. The knife unit (as pictured) features a 20" rippled coulter that cuts a slot for the knife. Fertilizer is placed at the knife depth at low pressure. A variety of knife styles are available. Choose from a 1,250/1,600 gal. Hi-Rise Steerable trailer or a 1,025 gal. Hi-Rise Trailer. The Steerable trailers feature articulated steering to keep the trailer in the furrow. The CDS/John Blue piston pump can be mounted on the tool bar or the Hi-Rise trailer.
