GENERAL INFORMATION The 2959 Fertilizer Coulter can be used as a R.H. opener or a L.H. opener, it is recommended that half of the planter is R.H. assemblies and the other half is L.H. assemblies. NOTE: The 2959 Fertilizer Coulter is NOT recommended for use in rocky conditions as the coulter arm and fertilizer tube are susceptible to bending. For proper operation of the 2959 coulter, a ¼” NPT “Straight Stream” nozzle or a ¼” NPT Female “Nozzle Body” with orifice plates will be required.
ASSEMBLY INSTRUCTIONS STEP 1. Attach the 2959-203 fert. coulter faceplate w.a. to the planter unit using 3) ½-13 x 1 ½” bolts, flat washers and locknuts. Use the 1 ¾” OD x ¼” thick washer on the lower large slot. On some planter units, this washer may need to be trimmed enough not to interfere with a gusset. Center the bracket on the row unit and tighten the bolts to specification listed on the table on page 4. STEP 2.
ASSEMBLY INSTRUCTIONS STEP 3. Depth settings are in reference to the planter frame being level (front to back) when in planting position. Depth settings are in relationship to the planter disc opener blades being 15” in diameter and the fertilizer coulter blade being 16” in diameter. The coulter blade has 6 adjustment settings in a 2” range, with a maximum operating depth of 4” below the surface.
ASSEMBLY INSTRUCTIONS STEP 5. At the pipe coupler install the appropriate nozzle (not supplied) according to the liquid fertilizer application rate.
