Air Flow & Hose Routing The centerline of the goose neck arms hitch point (center of balls or knuckle hitch bolts) to the furthest back part of the row unit or bar attachment can be NO GREATER THAN 4 6 for tire clearance on turns. If you use the Montag supplied parts for your machine, make the hose runs as short and flat as possible and it looks nice when you are done you will have an efficient running system.

Air Flow & Hose Routing Run the long hose first and fold bar to see how much hose you need and how it reacts when folded. Building brackets and mounting the air releases can save some down time in the field.

Air Flow & Hose Routing

Air Flow & Hose Routing The Air Release The Hooded Vent Air Release has a cover and tube that directs the air and any fertilizer dust in a back and downward direction. It can also be fitted with a short piece of tubing (no longer than 36 ) to further direct the air and dust away from the toolbar and tooling. If the fertilizer tube should plug the fertilizer would be exhausted down with the air. The Open Vent Air Release simply vents the air and any fertilizer dust in a forward and upward direction. This makes it very easy to see when a fertilizer tube is plugged below the air release, as the fertilizer is blown up into the air.

Hooking up the Hydraulics and Case Drain Alarm 1. The zero pressure case drain alarm cable gets routed to the tractor cab and hooked to 12 volt DC + and terminals. This will warn the operator if the pressure on the case drain line is above 23 PSI. Hooking up the Hydraulics 1. The port marked CD on the front of the hydraulic block MUST return to the zero pressure or case drain return port on your tractor. The port marked P on the front of the hydraulic block is the Inlet Pressure port. It gets hooked up to the pressure side of the valve stack on your tractor. 2. See the Hydraulic Schematic for your system to determine the return line connection. The return oil from the system should return to a hydraulic motor return port on your tractor. Not the valve stack. If you do not know the location of these ports on your tractor please contact your local tractor manufacturer s service department. 3. When everything is plumbed correctly and the Montag is running, the gages on the hydraulic block should read as follows. GP port (on the left) is the inlet pressure 1500-2850 PSI depending on the number of rows. Lower pressure for 8 row machines and higher pressure for 24 row machines and Twin Bins. The GT port (on the right) Return Pressure should read 0-200 PSI. If it is higher than 200 PSI make sure it is returning to a hydraulic motor return port and look for any restrictions in the line at fittings, couplers and hoses. The lower you can keep the return pressure the more efficient your system will operate. Model Rows Hyd. Capacity Hyd.

Twin Auger Drive 14 Tooth drive sprocket on the auger motor (bottom sprocket) 22 tooth driven sprockets on augers makes the 1.57 to 1 ratio.

Auger Motor with 12 Volt Speed Sensor New auger drive motor with 12V 60 pulse speed sensor. The drive runs at a 1.57 to 1 Ratio so the controller will actually see 94 pulses for 1 revolution of the auger.

EATON Speed Sensor Installation Information 1. Rotate the motor shaft until a (gear/target) tooth is centered in the speed sensor port. If this is not done, the sensor may be damaged during the operation of the motor. 2. Make sure the lock nut and its threads are clean and dry for the proper torque. Position the lock nut against the alignment nut as shown in Figure 1. 3. Move the washer and the o-ring up against the speed sensor body threads as shown in Figure 1. 4. By hand, lightly thread the speed sensor body into the housing until the sensor touches against the motor (gear/target) tooth. Do not force the sensor against the (gear/target) tooth, damage may occur. Make sure the o-ring or the washer do not touch the housing see Figure 2. 5. Turn the speed sensor body out one quarter turn (CCW) plus the additional amount (CCW) needed to make the alignment notches perpendicular to the motor shaft centerline (90 +/-5 degrees from the motor shaft centerline Figure 3 and 4). 6. Maintain the speed sensor body alignment (Figure 4), and tighten the lock nut to 8,5-14 Nm [75-125 lb-in.] (torque values are for clean dry threads). 7. Check the speed sensor body for correct alignment (Figure 4), reinstall the sensor if it is not correct.

Typical Controller Calibration for 30 inch Rows: Set your product density to 62, your application rate to 250 lbs. / acre, test speed at 5 MPH and run the controller in test mode. The auger shaft should turn 60 RPM for a standard machine and 31 RPM for a High Output machine. If it does not you can raise or lower your CFR # or Spreader Constant # to achieve the proper RPM.

The Scale Kit

The Scale HOW TO INSTALL THE GEN I SKID ON THE CART (WITH OPTIONAL WEIGH BARS) 1. Position weigh bars (A) on cart brackets at each corner with arrows on ends of weigh bars pointing down. Ends of bars with arrows must be farthest from cart center frame (B). 2. Install each weigh bar to bracket loosely with two ¾ x 3 inch bolts (C), through two bolt holes closest together, and ¾ inch lock nuts. Do not tighten at this time. 3. Position skid with fertilizer tank onto cart, with skid bolt holes aligned with bolt holes in four weigh bars. 4. Install ¾ x 2½ inch bolts (D) with flat washers at each skid corner through skid brackets and weigh bars. Tighten bolts to 220 lb/ft (271 Nm) of torque. Note: Skid with dry or liquid fertilizer tank is fastened to weigh bars. Tighten weigh bars to prevent skid from coming loose. 5. Tighten bolts (C) to 220 lb/ft (271 Nm) of torque. Note: Back-up bolts (E) are installed as a safety measure in case any skid mounting bolts come loose or fail. Install both back-up bolts loosely. Fertilizer tank load readings will include any force applied by these bolts. 6. Install back-up bolts (E) on each side of skid below meter with spacers under bolt and lock nut, but do not tighten bolts. Bolts must have approximately ⅛ inch of play after installation. 7. Route lead from each weigh bar to junction box (F). Connect leads to junction box terminals. See Section 10 Appendix for instructions. Do not cut wires.
