Abstract
A single disk fertilizer opener assembly for opening a trench in soil includes a frame support and a cutting disk for forming the trench. The cutting disk is coupled to an axle and rotates about the axle as the assembly moves in a working direction. The assembly also includes a first arm pivotally coupled to the frame support and the axle, and a second arm pivotally coupled to the frame support at a location spaced from the first arm. A bracket is coupled to the axle and the second arm, and a scraper is coupled to the bracket and disposed substantially perpendicularly to the working direction.
