4 SeedCommand Ag Leader Technology Preliminary Installation Requirements Implement must be lowered to ground or resting on hydraulic safety stops before beginning installation. Do not rely on hydraulic system alone to support implement. Hydraulics can fail resulting in serious injury or death. Read these instructions completely before beginning installation. They cover multiple clutch setups, so a thorough understanding is essential before beginning. Pay particular attention to Figures 1, 2 & 3. They may help to clarify any questions that arise about the installation. 4 April 2013 Rev C

8 SeedCommand Ag Leader Technology Installing Clutch and Output chain Required Parts: Part Number: (1) clutch (3) Carriage bolt 1/4 in. x 1 in (3) Hex nylock nut 1/4 in (3) Flat washer 1/4 in (1) Drill bit 9/32 in (1) Transfer punch 11/32 in (1) Output chain Deere NON-INTERPLANT (1) Drill template John Deere (Above quantities are for one row unit) Optional parts: (1) Output chain Deere INTERPLANT Step-by-Step Procedure 1. Remove seed meter assembly from row unit. 2. Find connecting link on seed meter drive chain and remove outer retaining clip. Next remove tension from chain by pressing top of chain tensioner down and remove chain from seed meter drive sprocket. Finally remove connecting link and remove chain from row unit. 3. Remove chain tensioner assembly from row unit. All pieces from chain tensioner assembly will be reused in later steps except for the through bolt and retaining nut. (See Figure 4.)

9 Ag Leader Technology SeedCommand 4. Find template that is included in kit. Install template on inside of row unit as shown in Figure 5. Template may be held in place with C-clamps. 5. Using supplied center punch, mark three holes in row unit. Remove template from row unit. 6. Using drill and supplied 9/32 in. stubby drill bit, drill out holes that were marked in previous step. After holes have been drilled, check to see if any burrs are left and remove if necessary. Figure 5: Drill template installed inside of row unit Note: Align bottom of template with bottom of row unit side. Align right side of template with left side of row unit frame as shown in Figure 5. Before marking holes, make sure template does not slide between row unit side plate and row unit frame. 7. Install clutch on inside of row unit using 1/4 in. x 1 in. carriage bolt, 1/4 in. washer and 1/4 in. lock nut. Do not tighten nuts at this time. PN: April 2013 Rev C 9

10 SeedCommand Ag Leader Technology 8. Install output chain on seed meter sprocket and inside sprocket of clutch. Tighten chain by sliding clutch towards front of row unit and tighten three (3) nuts that attach clutch to row unit as shown in Figure 6. DO NOT over tighten chain. Chain should have 1/8 to 1/4 in. of slack midway between sprockets. Figure 6: clutch with output chain installed 10 April 2013 Rev C

11 Ag Leader Technology SeedCommand Installing Spacer Washers on Drill Shaft Required Parts: Part Number: (2) Hex head capscrew 3/8 in. x 1-1/2 in (2) Hex nylock nut 3/8 in (4) Flat washer 3/8 in (Above quantities are for one row unit) Optional parts: (2) Hex head capscrew 3/8 in. x 1-3/4 in (2) Bearing hanger spacer Step-by-step Procedure 1. Remove two (2) bolts and two (2) nuts from bearing hanger on drill shaft. Slide bearing hanger towards inside of row unit and out of the way. 2. Install two (2) 3/8 in. x 1-1/2 in. bolts from outside of planter frame through holes where previous bolts were removed. If planter is equipped with air bags or outside down pressure please see note on next page. 3. Install two (2) 3/8 in. flat washers onto each bolt from inside of row unit (See Figure 7). Slide bearing hanger into position and install 3/8 in. locknuts and tighten. Spacer washers Figure 7: John Deere OEM bearing hanger with spacers washers installed PN: April 2013 Rev C 11

12 SeedCommand Ag Leader Technology Note: The input sprocket on the drill shaft and the input sprocket on the clutch will be approximately 3/8 in. out of line. The reason for this is the fact that the planter input sprocket cannot be spaced over far enough due to the heavy duty down pressure spring and the slot in the row unit frame. If planter is equipped with air bags or outside down pressure springs, the slot in the frame of the planter shown in Figure 8 can be ground or cut out to allow the chain to run more closely in line with the clutch. After the material has been removed follow the steps below to reinstall the bearing hanger. 1. Install one (1) 3/8 washer onto each of the supplied 3/8 x 1-3/4 bolts. 2. Install the bolts into the slots where the bearing hanger bolts were previously removed. 3. Next install two spacers onto the bolts from inside the row unit as shown in Figure Finally slide the bearing hanger over the bolts and install the two (2) 3/8 locknuts onto each bolt and tighten. Be sure to check for clearance between the chain and the row unit frame before operating the planter. Ag Leader also supplies a chain that is made to allow for some misalignment of sprockets. Field results and testing has shown that there is no additional wear on the chain or sprockets due to the slight misalignment. Remove material from slot to align sprockets Figure 8: Material removal location 12 April 2013 Rev C

14 SeedCommand Ag Leader Technology Installing Chain Tensioner and Input Chain Required Parts: Part Number: (1) Carriage bolt 5/16 in. x 5 in (1) Hex nylock nut 5/16in (1) Spacer 3/8 in. ID x 5/8 in. OD x 1-1/2 in. long (2) Flat washer 3/8 in (1) Input chain Deere NON INTERPLANT (Above quantities are for one row unit) Optional Parts: (1) Input chain Deere INTERPLANT Step-by-step Procedure 1. Install 5/16 in. x 5 in. bolt through original hole for tensioner in side of row unit frame. 2. Install hardware onto bolt in the order shown in Figure 10. Tighten 5/16 in. nut on chain tensioner. Spring orientation is shown in Figure Install input chain in the orientation shown in Figure 11. Input chain comes pre-assembled. Chain MUST be disassembled before it can be installed on row unit. 5/16 in. x 5 in. bolt Flat washer 3/8 in. OEM spacer OEM washer Spacer 3/8 in. ID x 5/8 in.

15 Ag Leader Technology SeedCommand Note: If row unit is equipped with row unit set back bar, additional links will need to be added to input chain. To find the approximate number of links needed, first determine the amount of set back by measuring from center of bolt that attaches bar to row unit frame to center of bolt that attaches parallel arm to set back bar. Next use the following formula to determine number of links: set back distance (inches) x 4 = # of links. Finally check to make sure row unit goes through entire range of motion and there is no chain bind. Optional: John Deere Interplant row unit 4. Interplant row units require the use of a longer input chain. Procedure for installing the chain is the same as in step Reinstall seed hopper and seed meter assembly. Repeat procedure for additional three (3) row units. Front of row unit Spring C clip end Spring tang Figure 11: Input chain orientation Note: Install spring as shown in Figure 11.
