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.
Claims20
A single disk fertilizer opener movable in a working direction for opening a trench in soil, comprising:
- a frame support;
- a cutting disk for forming the trench, the cutting disk coupled to an axle and configured to rotate about the axle;
- a first arm including a first end and a second end, the first end being pivotally coupled to the frame support and the second end being pivotally coupled to the axle;
- a second arm including a first end and a second end, the first end being pivotally coupled to the frame support at a location spaced from the first end of the first arm;
- a bracket coupled to the axle and the second end of the second arm;
- a boot coupled to the bracket;
- and
- a scraper removably coupled to the boot;
- wherein, as the first and second arms pivot relative to the frame support, the boot remains positioned substantially perpendicular to the working direction.
