Assembly Instructions:
1. Assemble blades to twin coulter hub as shown using ½” X 1 ½” carriage bolts and lock
nuts provided. Note: nothing on hub assembly needs to be taken apart, hub plates are
designed to be on inside of blade.
2. The bearings are pre-greased and sealed, there is no need for additional grease.
3. Attach Twin Coulter Assembly to shank as shown in following diagrams. Assembly can be
mounted in two configurations shown, assembly
CAN NOT be mounted to rear of shank.
4. Two carriage bolts are provided to attach Twin Coulter Assembly to shank, if length pro-
vided is not sufficient, use only Grade 5 longer Carriage bolts.
5. Use Shim (PN 8J2110) provided to fill gap between side of the weldment and shank.
Secure with bolt 8X0072 and 8X0244 nut. Tighten bolt 8X0072 so side tab of weldment
begins to deform and presses shim against shank. Bolt may deform during this step. If
no shim is needed to fill gap, tighten cross bolt so side tabs of weldment touch shank. Ad-
ditional shims may be ordered if needed for narrow shanks.
