Figure 6. Upper actuator bracket assembly in position 9. Slide upper actuator bracket assembly onto front of row unit so that support plate is in front of row unit mounting plate and adapter plate is behind it as shown in Figure 6. Loosely install 5/8 x 1-3/4 in. bolts into lower mounting holes of adapter/support plates. 10. With upper 5/8 in. mounting bolts resting on row unit mounting plate, align upper actuator bracket assembly so that actuator mounting hole of upper bracket is vertically aligned with actuator mounting hole of lower bracket. Vertical alignment does not have to be perfect because actuator bases are designed to handle some misalignment. However, perfect alignment should be the goal. 11. After aligning upper actuator bracket, fully tighten all (4) 5/8 in. mounting bolts. An open-end wrench will be required for upper mounting bolts as illustrated in Figure 6. 12. Mount anti-rotation bracket to actuator such that long ear of bracket is toward hydraulic fittings of actuator using 1/4 x 3/4 in. bolts with split lock washers as shown in Figure 7.

Installing Hydraulic Valve Block Required Parts: Part Number: (1) Hydraulic valve manifold 3 section 4004265 (1) Hydraulic valve manifold 4 section 4004266 (1) Hydraulic valve manifold 6 section 4004267 (1) Hydraulic valve manifold 8 section 4004268 (1) Valve block bracket 4004362 (1) Valve block angle bracket 4004363 (1) Valve block strap bracket 4004364 (4) Hex head bolt 3/8 x 1 in. 2002003-38100 (2) Carriage bolt 1/2 x 1-1/4 in. 2002021-50125 (2) Carriage bolt 1/2 x 2-3/4 in. 2002021-50275 (2) Hex nut 1/2 in. 2002051-50 (2) Hex lock nut 1/2 in. 2002055-50 (4) Split lock washer 3/8 in. 2002061-38 (2) Split lock washer 1/2 in. 2002061-50 (4) Flat washer 1/2 in. 2002071-50 (2) Carriage bolt 1/2 x 7 in. 2002121-0507 (2) Carriage bolt 1/2 x 12 in. 2002121-0512 (2) Carriage bolt 1/2 x 14 in. 2002121-0514 Valve Block Key Features and Definitions: Operating Modes a. Automatic The down force system is configured from the factory to operate in automatic mode. This is the closed-loop control system that adjusts down force automatically based on feedback from the load sensors. No action is required from the operator to adjust the down force. b. Manual This is an optional mode giving the operator control of the amount of down force across the entire planter. The electronics are required to use this mode. c. Override In the event of a complete electronic system failure, the down force system can be switched to override mode so that planting may continue. In this scenario, each channel s solenoid valve must be disconnected from the control harness. This is because the electrical signal is additive to the override setting (using both may create excessive down force). Each channel valve must then be mechanically adjusted using a 3/16 in. hex key (turn CCW to decrease channel pressure and vice versa). Monitor channel pressure via test port to set desired pressure (down force) while turning override hex key. Test Port There is a quick-connect port on the back side of the valve block that corresponds to each channel. It can be used for implementing the override function using a gauge test kit (P/N: 4100164). It is also useful for diagnosing channel irregularities. PN: 2006232 December 2014 Rev A 20

1. Secure valve block bracket to valve block using provided 3/8 in. bolts with lock washers as shown in Figure 20 & 21. Multiple mounting holes in the different valve block configurations allow for flexibility in mounting. A minimum of 3 (in some cases 4) bolts will be used. Mounting bolts Figure 20. Mounting bracket installed on 3-channel valve block Mounting bolts Figure 21. Mounting bracket installed on 8-channel valve block PN: 2006232 December 2014 Rev A 21

2. Next, determine a mounting location as close to center of toolbar as possible (provided hose lengths are based on valve block being within 5 ft of center of toolbar). See Figure 22 as an example. For bulk-fill planters, the bulk-fill tank framework and catwalk provide additional mounting options. Make sure there is adequate clearance around channel ports for hoses to be connected in a following section. NOTE: Valve block may be oriented vertically, horizontally, or anywhere in between as long as the solenoid valves are level (parallel with the ground) when in planting mode. These valves do not work properly with air in them, so it is imperative that they are level. Bleeding the system of air is also imperative, which will be covered in a later section. Valve block installed under catwalk Figure 22. Front-fold bulk-fill planter (KZ 4900 shown) NOTE: Steps 3 & 4 can be done in reverse order if it makes more sense to do so. Keep in mind that hose fittings on valve block must be accessible with a wrench as you finalize mounting location. That will make installing hoses much easier in the following section. 3. With mounting location determined, secure angle and strap brackets to planter frame using provided 1/2 in. carriage bolts with flat washers and lock nuts as shown in Figure 23. Different length carriage bolts are provided for versatility. Existing bolts on planter, or threaded rod can also be used. PN: 2006232 December 2014 Rev A 22

The down force system will bleed down pressure in a power down scenario. For safety, please allow 10 minutes after the tractor SCV is turned off and the planter has come to a rest before disconnecting any hoses from the down force system (including the tractor hoses). This will eliminate the hydraulic pressure trapped in the system so that it can be safely serviced. NOTE: It is standard for pressure, return and tank hoses of hydraulic down force to be routed to front of planter to be connected directly to SCV of tractor. If desired, these hoses can be connected to an existing valve block (if equipped) near rear of planter to eliminate running hoses to the front. 1. Locate PRESSURE, RETURN and TANK hoses and connect to appropriate ports of valve block (labeled P, R & T respectively). P, R & T port fittings can be reoriented as necessary to optimize hose routing. Hoses come equipped with quick-connect couplers for connecting to tractor. Pressure and return lines have the same couplers. Tank coupler is different. See Figure 25 for proper hose identification. Return (1/2 in. hose) Pressure (3/8 in. hose) Tank (1/2 in. hose) Figure 25. Pressure, return & tank hose identification PN: 2006232 December 2014 Rev A 25

2. Connect pressure, return and tank lines to tractor. Ideally, PRESSURE and RETURN hoses should have a dedicated SCV. If that is not possible, tee fittings are available to tee into existing hoses. Ag Leader recommends sharing Down Force with same SCV as hydraulic drive for variable rate seeding if sharing is necessary (EXCEPTION: DO NOT SHARE SCV WITH RAWSON DRIVES). Hydraulic remote will need to be put into continuous flow, or motor mode. Refer to tractor operator s manual for proper hydraulic remote configuration when continuous flow is required. Not all tractors have a zero-pressure tank port. If not, port must be added. NOTE: If connecting to an SCV as described above is not an option or not desirable, power beyond load sense hydraulic hose kits are available from Ag Leader. Connecting to the power beyond will enable the pump to maintain a lower pressure when demand is low and therefore may help to reduce heat in hydraulic system. Refer to TSB-003041 (Tech Support Bulletin) for additional information. 3. Connect 3/8 in. (-6) channel hoses to valve block and route to row units as shown in Figures 26 32. The row units in the following figures with black fill and C1...C8 in white font are the row units that should have a channel hose routed to them. C1 is channel 1, C2 is channel 2, etc...

4. With channel hoses routed back to appropriate row units, connect #6 to #4 adapter to channel hoses. Then connect channel hoses to upper hydraulic port of actuator. The upper port should always be connected first because it is difficult to get a wrench on upper fitting if lower fitting is connected. 5. Take another look at Figures 26-32 to find your planter configuration. If any row units have a J1, or J2 on them, a 1/4 in. (-4) hydraulic jumper hose must be installed between the two row units with the same jumper designation. The jumper hose(s) allow two row units to be on the same channel across fold points, where a standard 50 in. row hose would not suffice. 6. With channel and jumper hoses (where applicable) routed and connected to appropriate actuators, route and connect 1/4 in. (-4) row hoses from row to row within each channel. It is not critical for operation, but for consistency bring oil out of lower actuator port and into upper port of next actuator down the line. For ease of installation, always tighten upper fitting before connecting lower fitting of each actuator. 7. Install a bleeder valve into lower (for consistency) hydraulic port of actuator at end of each section CAUTION: Make sure bleeder valve is closed to prevent hydraulic leaks when pressurizing system for the first time. 8. Fold and unfold planter carefully while observing newly installed hoses and cables in pivot points. Make adjustments as necessary to keep hoses and cables from being damaged. 9. With hydraulic hoses finalized, bleed hydraulic system as follows: a. Close all bleeder valves. b. Lower planter to contract hydraulic actuators. c. Energize down force system by turning on relevant SCV of tractor. SCV must be in motor mode (continuous flow) for proper operation of down force. d. With display powered up and down force configuration activated, toggle display from auto to manual mode. In manual mode, generate a low pressure (<1000 psi) to minimize oil splatter while bleeding system. e. One bleeder at a time, slowly open valve until air bubbles disappear. It works well to install a 1/4 in. hose from bleeder to a container of some type to minimize oil spills. f. After all bleeder valves have been bled one time, repeat process for each valve one more time. 10. Installation of down force system is complete unless uplift springs will be used. In that case, proceed to the following section. PN: 2006232 Dec 2014 Rev A 33

Installing Uplift Springs (Optional) Required Parts (quantities listed are per row): Part Number: (2) Uplift spring assembly Kinze 3000 4003478 (2) Uplift spring Kinze 4000 4003928 (3) Shoulder spacer 4004050 (1) Spacer 4004048 (4) Flat washer -.82 OD x.40 ID 2002487-8240 (1) Hex head bolt 3/8 x 3 in. 2002412-38300 (2) Hex head bolt 3/8 x 2 1/4 in. 2002401-38225 (1) Hex head bolt 3/8 x 1 1/4 in. 2002401-38125 (2) Lock nut 3/8 in. 2002055-38 (1) Lock nut 3/8 in. (thin) 2002286-38 NOTE: Uplift springs are not required in all cases. Bulk-fill planters in no-till conditions will probably not require any uplift assistance. At the other end of the spectrum, planters with individual seed boxes in conventional tillage conditions could benefit the most from uplift springs. 1. Raise row unit to its upper limit using a jack, forklift, or whatever other method is available to you. 2. Install uplift springs on a Kinze 3000 row unit as follows: 2.1. Position spring assembly on parallel arms so that triangular bolt pattern of spring brackets are pointing up as shown in Figure 33. 2.2. Fasten spring brackets to parallel arms using provided 12 x 70mm bolts with serrated flange nuts. Insert bolts from the outside with flange nuts installed on the inside of parallel arms. 3. Install uplift springs on Kinze 4000 row unit as follows and as illustrated in Figure 34: 3.1. If actuator is installed, remove cotter pin, castle nut and two washers from top stud so that actuator can be removed from top bracket. This is necessary to complete steps 3.4 & 3.5. 3.2. Secure uplift springs to lower bracket using provided 3/8 x 2-1/4 in. bolt in right-rear mounting hole and 3/8 x 2 in. bolt in left mounting hole with 3/8 in. flat washers, shoulder spacers and lock nuts. 3.3. Install a 3/8 x 1-1/4 in. bolt in right-front mounting hole of lower bracket if that has not already been done (as mentioned in step 5.2 on page 15). 3.4. Secure upper end of left spring using provided 3/8 x 2 in. bolt with a spacer, 3/8 in. flat washer and lock nut as shown. 3.5. Secure upper end of right spring using provided 3/8 x 3 in. fully threaded bolt, threaded shoulder spacer (fully tighten), bushing, stabilizer bracket, fender washer, shoulder spacer, standard 3/8 in. flat washer and lock nut as shown. Note that the stabilizer bracket rides on the bushing that can rotate freely around the threaded shoulder spacer. PN: 2006232 Dec 2014 Rev A 34
