INTRODUCTION The 2960-130 Unit Mounted Double Arm Conservation Coulter has been designed as a ‘universal’ fitment for several makes of planter units. By using two different arrangements of the same parts, the coulter assembly will fit several makes and models of planters. One arrangement of the faceplate mount brackets will fit the John Deere MaxEmerge 2, Plus, and Pro type planters.
COULTER INSTALLATION 1. Attach the double arm coulter assembly to the planter row units at the upper breastplate mounting holes using 2) ½” x 1 ½” bolts, flat washers and lock nuts. 2. Insert the 2) ½” x 1 ½” carriage bolts through the mount straps (long side toward center of row) breast plate mounting holes and secure with lock nut. 3. Align the coulter blade with the planter opener blades by sliding the coulter assembly on the planter breastplate, and then tighten the fasteners (torque to 85 ft. lbs.
OPERATION Note: This is a reference guide table – all measurements were taken with the row unit and planter frame level/parallel to the soil. COULTER BLADE DEPTH ADJUSTMENT BOLT LOCATION Adjustment: Adjust coulter blade depth equal to or above the planter opener blades. Adjust the blade depth as required for blade wear. Planter blades that are worn to 14 ¼” or smaller in diameter should be replaced.
OPERATION 1. 2. 3. Set/mount coulter blades to run perpendicular to the soil. Operation depth and blade wear can be affected if the coulter is mounted crooked or if the toolbar is not level side to side. After a few hours of use, check all bolts for tightness and proper torque. After a day of use (10-12 hours) check coulter hubs for loose bearings. There should be no endplay in the hub bearings allowing the blade to wobble.

TROUBLESHOOTING Problem Cause Solution Planter frame not set correctly. Ensure that in operation the planter frame is at correct height (20”-22”) and level the toolbar, refer to opposite page. Coulter blade is too big. Blade must be 16” diameter or smaller. Planter opener blades worn. Replace planter opener blades if worn smaller than 14 ¼” diameter. Cannot adjust coulter deep enough. Coulter blade worn too small. Replace coulter blade. Coulter will not penetrate. Lack of spring tension.
PLANTER HEIGHT ADJUSTMENT Figure A. – The planter hitch and frame are both 20” off the ground. To ensure this, visually check to see that the planter boxes are level and that the planter unit parallel arms are also parallel with the ground. When using planter attachments located in front of the planter unit, this setting is very important. Figure B.
Our name Is getting known Just a few years ago, Yetter products were sold primarily to the Midwest only. Then we embarked on a program of expansion and moved into the East, the South, the West and now north into Canada. We’re even getting orders from as far away as Australia and Africa. So, when you buy Yetter products . . .you’re buying a name that’s recognized. A name that’s known and respected.
