4 ACCIDENTS CAN BE PREVENTED WITH YOUR HELP! No accident-prevention program can be successful without the whole-hearted cooperation of the person who is directly responsible for the operation of the equipment. A large number of accidents can be prevented only by the operator anticipating the result before the accident is caused and doing something about it. No power-driven equipment, whether it be transportation or processing, whether it be on the highway, in the harvest field, or in the industrial plant, can be safer than the person who is at the controls. If accidents are to be prevented--and they can be prevented--it will be done by the operators who accept the full measure of their responsibility. It is true that the designer, the manufacturer, and the safety engineer can help; and they will help, but their combined efforts can be wiped out by a single careless act of the operator. It is said that, "the best kind of a safety device is a careful operator." We, at Unverferth Mfg. Co., Inc. ask that you be that kind of operator SAFETY PRECAUTIONS Read this manual carefully before operating. Never enter the grain cart while the auger is running. Make sure PTO guard is kept in place. Never allow anyone on the unit while moving through the field. Be careful when moving unit near electrical lines with discharge auger up. Never tow a loaded unit more than 8 m.p.h. or on a road. Never exceed the maximum recommended hitch pin size which allows for uneven terrain. Make use of night-time lighting provided on your new cart. Use caution when unloading on the go, while moving through gullies, washouts, and uneven terrain. Always check behind you before backing up. Counter-weight your tractor front end. Be careful on steep slopes. A loaded grain cart is hard to stop. Do not fold or unfold auger while moving. When auger is not in use, be sure to fold to the rest position. Never unhook a grain cart while it is being loaded. Turn the tractor power off and remove the key from the ignition before servicing the attached implement. Tow only an empty cart on-road and have a rated safety chain attached

Once seats are damaged, it will become impossible to keep nuts tight. Tighten nuts to 400 ft. lbs. Re-tighten after first three loads and check periodically during first season of use. TIRE PRESSURE The following is to be used as a general guide for tire inflation and figures can vary depending on specific brand of tire used. It is important that tires are inspected after unit is loaded. The tire should stand up with no side wall buckling as tire rolls x Lbs x Lbs x Lbs x Lbs x Lbs. 420/80 x Lbs. For questions regarding new tire warranty, please contact your local original equipment tire dealer. Used tires carry no warranty. Tire manufacturers' phone numbers and websites are listed on page 1-24 for your convenience. VERY IMPORTANT...NEVER tow a loaded grain cart in excess of 8 m.p.h

7 SET-UP DRIVELINE STORAGE Storage brackets are located on the inside right frame rail. Secure the PTO shaft to these brackets for extended transporting or seasonal storage. IMPORTANT: Remove and store the complete PTO before towing grain cart behind a delivery truck. Interference could occur when turning resulting in damage to PTO and cart DRIVE SHAFT SAFETY GUARDS The PTO drive shaft shield, floating guard tube and U-joint guard are factory installed. Make sure they are in place before operating the auger H PLASTIC HOSE PIPE INSTALLATION Place plastic hose pipe through the front standard and hose retainer on ladder. Slide the hoses through the plastic hose pipe. Set a desired hose length. Fasten the hoses and plastic hose pipe with the hose clamp behind the front standard. The wiring harness will also be run through the plastic hose pipe. Fasten harness to the hoses with tie straps. NOTE: It is recommended that any excess hose or wiring harness be contained at the rear of the hose pipe

8 ELECTRICAL HOOK-UP Your Grain Cart is supplied with a seven-point SAE connector plug which will adapt to the receptacle found on several new tractors on the market today.

9 SPINDLE DUAL WHEELS 1. If necessary, replace existing wheel studs with longer 3/4-16 UNF x 3 1/2" studs. INSIDE DUAL WHEEL: 2. Install inside dual wheel. 3. Use 3/4-16 hex jam nuts (27/64" Thick) on small holes. 4. Tighten the five jam nuts to 200 Ft. Lbs. OUTSIDE DUAL WHEEL: 5. Install outside dual wheel with the five large holes indexed over inside wheel nuts. 6. Use washers and 3/4"-16 UNF Grade 8 nuts on all studs. 7. Tighten the ten nuts to 400 Ft. Lbs

10 TRACTOR HOOK-UP -- Make sure sufficient counter-weight is used on the tractor's front-end. -- Move draw bar into closest position for even terrain. -- Make sure draw bar length and PTO telescoping limits are adequate for uneven terrain, gullies, rice levees etc. -- Never exceed the maximum recommended hitch pin size which allows for uneven terrain. See Chart below. -- Install hardened washer of hitch pin diameter between bottom of swivel ball and tractor draw bar HITCH 1-10 PIN SIZE A CLEVIS, RIGID (Scale Only) 1 1/4" B SINGLE TANG SWIVEL (Scale Only) 1 1/2" / 2" C SINGLE TANG SWIVEL (Non-Scale) 1 1/2" D SINGLE TANG SWIVEL & HAMMERSTRAP (Non-Scale) 1 1/2" HYDRAULIC HOOK-UP -- Properly identify the hoses for the auger fold and the flow control operation. -- It is advisable to use the hydraulic control lever closest to the operator (most commonly known as control lever No. 1) to activate the flow control. OPERATION IN FIELD IMPORTANT!! USE FULL SIZE PIN IN BALL SWIVEL. FAILURE TO USE THE RECOMMENDED HITCH PIN SIZE AND APPROPRI- ATE WASHER CAN CAUSE PREMATURE FAILURE OF SWIVEL BALL AND TRACTOR DRAWBAR. 1. Make sure the flow control door is in the closed position before loading into the cart. 2. Engage PTO at a low RPM; increase tractor RPM to desired speed. 3. Open the flow control to desired rate. 4. Use the flow control opening to slow the rate of the flow rather than the tractor's RPM. NOTE: If overload causes the clutch to slip (standard PTO drive) or motor to stall (hydraulic drive), stop auger immediately. Excessive heating of the clutch will require replacement of internal parts. Close flow control door and relieve auger unload pressure by opening bottom pit dump door to remove some grain from auger. 5. It is not advisable to disengage the auger with the flow control open. Excessive start-up torque may result, putting stress on the cart driveline and your tractor. 6. Properly identify the tractor remotes as to hook-up the flow control and auger fold. A mix-up can damage the auger drive system. 7. Under any circumstances, DO NOT enter the cart with the auger or tractor running. 8. When folding the auger into the unloading position, make sure you have given sufficient time for the cylinder to rotate the bell crank into an over-center position. 9. It is strongly advised that the unloaded auger always be returned to the transport position when not in use

11 AUGER FOLD ADJUSTMENT The auger fold linkage is adjusted at the factory and under normal operating conditions should not require adjustment. Disassembly for service or slight wear in the linkage pins may necessitate the need for adjustment. The 1/8" compression dimension is necessary for a good seal at the auger flanges and snap locking at the end of the cylinder stroke. 1. Fold the upper auger into the operating position and clamp flanges to secure. 2. Extend hydraulic cylinder slightly (1/8") to relieve load. Remove T-Bar yoke pin. 3. Retract cylinder to end of stroke. 4. Rotate T-Bar yoke as necessary to position rockshaft arm hole approximately 1/8" past T- Bar yoke holes when T-Bar linkage and rockshaft arm are in a straight line. 5. Extend cylinder slightly again to line up holes in T-Bar yoke and rockshaft arm. Install pin and secure with nut. Remove temporary clamp before cycling auger fold operation. 6. Retract hydraulic cylinder. Check for sealing at auger tube flanges and for "straight-line lock snap" of linkage. Cycle linkage by fully lowering and raising auger tube. Recheck linkage. Readjust as necessary

12 HYDRAULIC AUGER OPERATION For PTO & DIRECT DRIVE Applications 1. Initial start-up: Flow Door is to be closed. 2. With flow door closed, engage hydraulic motor with maximum oil flow from tractor. NOTE: Free running auger oil pressure will range 500 PSI or less. 3. The pressure gauge will register system work load as flow door is opened. Slowly open flow door to #1 setting on auger tube decal gauge. While monitoring the auger discharge rate and hydraulic pressure, gradually increase flow door opening to approximately 2-2 1/2 setting. Watch the pressure gauge and stop opening door once pressure reaches 2000 PSI. 4. Peak performance is obtained by matching your highest continuous auger rpm to the flow door opening setting. It is necessary to initially monitor the auger speed and adjust the flow door UP or DOWN to arrive at the optimum output performance. If the flow door is opened too wide, the oil pressure will rise, but the GPM and the hydraulic motor RPM could slow down - resulting in less auger output. Also if the tractor has a higher GPM output, it is possible that the flow door could be opened wider and still maintain performance. 5. Bushels-per-minute output depends on the following factors: a. Oil flow (GPM) from tractor. b. Flow door opening setting. c. Grain moisture content. 6. The hydraulic motor is capable of handling 32 to 35 GPM. If extra hydraulic ports are available on the tractor, it is possible to increase oil flow to the hydraulic motor by teeing together two pressure ports to the single pressure hose, and teeing two hoses from return hose to the tractor return ports

13 ADJUSTABLE UNLOADING CHUTE (OPTIONAL) INSTALLATION: Remove existing chute. 2. Fold overlap and snap four end snaps. 3. Slide chute over outlet shroud with overlap towards hitch. 4. Install top and bottom strips over chute and fasten with existing capscrews, flatwashers and locknuts. 5. To adjust to desired length, unsnap overlap, roll chute on outside and snap in place. SCALE WEIGHING PROCEDURE Turn scale on and let it warm-up at least 15 minutes. Zero balance scale by pushing the "Net/Gross" button, and then the "Zero" button within 3 seconds. This should be done where cart is going to be unloaded (on level ground if possible). Load cart and let scale total up weight. When cart is full drive up to truck and stop. After scale settles on a number, push the "Tare" button. Scale indicator will show zero. Now start unloading cart. When truck is full or cart is empty, the negative amount shown on scale is actual product in truck. Now push the "Net/Gross" button. This will put the scale back into the gross weighing mode again. If the cart has grain in it yet, it will tell you how much weight is left on the cart. You can now load the cart again and repeat the same unloading process. You should try to get the cart empty a few times during the day so you can rebalance the scale

15 LUBRICATION AND MAINTENANCE To keep your grain cart in top operating condition and to assure its proper performance and reliability for a long period of time, a periodic inspection and lubrication is a must. The lubrication locations and recommended schedule are as follows: A. Three shots of grease weekly B. See chart C. Roll bearing and apply grease as required. Do not grease if cart has scale unit. D. Replace every season, 1 1/2 pints 90 weight oil E. One shot of grease daily F. One shot of grease per season G. Repack once every 2 years; adjust bearing take-up once per season H. Three shots of grease per week SERVICE TIPS DRIVELINE It is important to periodically check set screws in all bearings at either end of the driveline for tightness. U-JOINT The U-joint will give you several years of service if the following steps are taken: 1. Grease joint weekly 2. Grease spline weekly GEAR BOX -- Fluid level plug is on the right side of gear box -- Fill plug is in front of the axle on the left side of gear box (Standing behind the cart looking toward the tractor) For maximum gear box life: -- Check oil level every 2 weeks -- Replace oil every season, 1 1/2 pints 90 weight oil AUGER SYSTEM Annually check all bolts, nuts, and set screws. Perform lubrication as specified. NOTE: The lower auger position is indexed from the drive dog / tube flange hinge surface as shown. The lower drive dogs and height pin are positioned relative to the gear box and drive bushing. The alignment height of the auger can be changed by cutting loose and relocating the height pin

16 ADJUSTABLE AXLE - MODELS 672, 674 ADJUSTABLE AXLE (120" - 154") 1. Raise center axle weldment. 2. Loosen clamp plate capscrews on slotted slides of axle weldment 3, Extend axle to desired width and align holes for studs if greater than 144". 4. Remove axle stud and spacer pipe from storage brackets on rear of axle. Install in outer set of holes for desired axle width. 5. For an axle width of 144" or greater, move axle brace assemblies from front to rear holes on frame bracket. Loosen setscrews in turnbuckle and adjust to fit the extended axle ends. Tighten setscrews

DIGI-STAR SCALES ARE MANUFACTURED TO PROVIDE + 1/2% MAXIMUM ERROR. A GOOD INSTALLATION AND PROPER USE ARE REQUIRED IN ORDER TO OBTAIN ADVERTISED ACCURACY. A GOOD INSTALLATION REQUIRES THAT ALL LOAD CELLS ARE PROPERLY INSTALLED WITH "TOP" ACCURATELY POSITIONED. OPERATION TO INSURE + 1/2% MAXIMUM ERROR, THE UNIT MUST BE USED AS A STATIONARY LOAD-OUT WEIGH HOPPER FROM BIN TO TRUCK, FOR EXAMPLE, THE GROUND MUST BE SMOOTH AND LEVEL WITH MAXIMUM 5" SLOPE PER 10 FEET. TO INSURE + 1% MAXIMUM ERROR, THE UNIT MUST BE USED SO THAT ALL WEIGHT MEASUREMENTS OCCUR ON FLAT, SMOOTH GROUND (MAXIMUM OUT OF LEVEL 10" IN 10 FEET) IDEALLY, ALL WEIGHT MEASUREMENTS FOR A FIELD WOULD OCCUR IN THE SAME SPOT. WARNING! ALWAYS DISCONNECT CABLES FROM SCALE INDICATOR BEFORE JUMP STARTING ENGINE

50 SCALE KIT LAYOUT

51 INSTALLATION OF SCALE KIT FOR MODELS 672 & 674 HITCH ASSEMBLY 1. Remove the four 3/4 x 2 1/2" bolts ( ) and lockwashers ( ) to remove the standard hitch (250486). 2. Using the same bolts and lockwashers, install the scale hitch bushing (250487). 3. Before installing the 2 1/2" weigh bar (92400), feed the wire through the hole indicated in the drawing at left. After doing so, insert the 2 1/2" weigh bar. 4. Using the 1 x 6" bolt ( ), lockwasher ( ), and nut ( ), secure the 2 1/2" weigh bar. 5. Using a 1 x 7" bolt ( ), lockwasher ( ), and nut ( ) secure the clevis hitch (200004). Use the pin (250490) and two snap rings (94142) to secure the single-tang hitch (250494). J-BOX INSTALLATION 1. Install junction box on the back side of the left front frame standard (see drawing at left). 2. See page 3-6 for specific wiring installation instructions SPINDLE ASSEMBLY 1. With the cart empty, use a 5-ton jack and jack stands to support the weight of your grain cart. Place the jackstands under the axle, near the tire. 2. Remove the wheel & tire and the hub assembly. See part numbers below. 3. Remove the 5/8 x 6 bolt ( ), lockwasher ( ), and locknut ( ) to release the spindle. 4. Change the seal in the hub. 5. Using the same bolt, lockwasher, and locknut you just removed, add the 4 1/2" spindle bushing (200025) if required and the spindle. 6. Attach hub assembly and the original wheels & tires.

Using the bracket provided, locate the indicator inside the tractor cab. 2. Attach the cable as indicated on page

52 Turn ON the scale: 1. Press [ON] A brief message is displayed (such as "HELLO"). The scale enters GROSS weighing mode. Pressing [ON] a second time during normal system operation starts the self-test. A warm-up period of ten to fifteen minutes provides the most accurate readings. If the scale is holding a load for a long period of time (ex: overnight), the weight displayed may vary because of zero shift created by changes in temperature. This does not affect the accuracy of the scale. For example, if the system was loaded with 1000 Lbs, it might read 1200 Lbs the following day. The change in temperature "zero shifted" the ZERO/ BALANCE from 0 Lbs to 200 Lbs. When unloading the scale, the display will count from 1200 to 200 Lbs for a total of 1000 Lbs. Turning OFF the Scale: 1. Press [OFF]. HELLO 0 To Zero / Balance the Scale 1. Press the [NET/GROSS] key and within three seconds, 2. Press the [ZERO] key. ZERO The ZERO/BALANCE will "balance off" trailer, bin, or platform weight. The "ZERO" message is displayed and the scale is placed in the GROSS mode. Pressing only the [ZERO] key will cause the message "TO ZERO / BALANCE PRESS NET/GROSS -- THEN ZERO" to be displayed. If the supply power is below the "low battery threshold" (10.5 Volts), the message "INDICATOR CANNOT BE ZERO / BALANCED -- LOW BATTERY VOLTAGE" is displayed. The message "LO BAT" will be periodically shown on the display (approx. every five seconds) to alert the operator of the low battery condition. Loss of power does not affect the ZERO/BALANCE or "Setup/Calibration" values

53 To Select Gross Mode: GROSS mode displays the weight change since the unit was last ZERO/ BALANCED. 1. Press [NET / GROSS] NOTE: The scale is in GROSS mode if there is a flashing arrow pointing toward the GROSS text just above the [NET / GROSS] key. To Select Net Mode: Net mode displays the weight change after a TARE has been performed. TARE is a temporary "zero" or reference point. 0 or 2. If in Gross mode, press [NET / GROSS]. The [NET / GROSS] key is an alternating action key. If the scale is in the GROSS mode, pressing the [NET / GROSS] key will place it in the NET mode. If the scale is in the NET mode, pressing the [NET / GROSS] key will place it in the GROSS mode. If the "TARE" function has not been previously performed, the unit will stay in the Gross mode and the message "FOR NET MODE PRESS TARE" will scroll across the display. NOTE: The scale is in NET mode if there is a flashing arrow pointing toward the NET text just above the [TARE] key. To Print Scale data can be sent to the optional printer by pressing the [PRINT] key. The printer connector on the bottom of the indicator is also used to connect the optional downloader module memory converter. See page Press "TARE" to set a temporary "zero" point and enter the NET mode

54 OPERATION: It is recommended that the indicator reads 0000 by pressing TARE before unloading the cart in a truck or wagon. SCALE BOTTOM PANEL CABLE CONNECTIONS: Once the cart is finished unloading, the exact (negative) amount of grain unloaded is displayed. Press TARE to read 0000 again, or press NET/GROSS to display the amount of grain remaining in the grain cart. INSTALLATION Indicator Mounting: The indicator is easily attached to the Indicator Mounting Bracket by hooking the top over the plate and securing the bottom with two (2) bolts (size# 10 x 24 x 3/4") and nuts. Power Connection: The power cable should be connected directly to a vehicle battery or regulated power supply. The scale end of the power cable is attached to the J901 connector located on the bottom panel of the scale. Connect the RED wire from the power cable to +12 VDC and the BLACK wire to GROUND. The indicator is fused internally at 4 amps. POWER CABLE CONNECTIONS: WIRE COLOR WIRE FUNCTIONS RED Battery (+12 VDC) BLACK GROUND ORANGE Remote Alarm Out + BLUE Remote Input Remote Alarm Connection: If a remote 12 VDC alarm is to be used, connect the +12 VDC side of the alarm to the power cable orange wire and the GROUND side (or black wire) to the frame. The alarm output is fused for a maximum drain of 10 amps. The remote alarm connection may also be used for motor control purposes when used with a relay. Load Cell Connection: The indicator is designed to operate with strain gage load cells. The indicator will normally be supplied with a "J-BOX" cable going between the scale and the load cell junction box. Extension Kits are available from your dealer in various lengths. To connect the load cells, attach the junction box cable to the J902 connector on the bottom panel of the scale. Connect the load cell cables to the junction box as shown below.

55 "Short Form" Setup & Calibration: WARNING! THIS INDICATOR WAS CALIBRATED AT THE FACTORY TO WEIGH ACCURATELY WITH YOUR SYSTEM. ADDITIONAL CALIBRATION IS NOT NECESSARY UNDER NORMAL CONDITIONS. The Short Form Setup & Calibration procedure allows you to change the "SETUP" and "CAL" numbers of the indicator. You may want to perform this procedure if; or 1): The indicator is being connected to different load cells. 2): You want to adjust the calibration to match another scale system. PLEASE NOTE: Do not attempt to calibrate the scale if the indicator is not reading stable weights. The calibration procedure will not fix instability, inconsistencies, or flashing "RANGE" messages. Before continuing, first write down the current "SETUP" and "CAL" numbers of your EZ indicator. These numbers are displayed during the "Self Test". To run the Self Test: With the indicator already ON, press the [ON] key to start the Self Test. Press the [ON] key to "pause" the Self Test while numbers are displayed. Press [ON] again to "resume". SETUP# CAL# Keep this information for future reference. 1: Adjust EZ Indicator to Match Another Scale: Sometimes two different scales are used to weigh the same load. When this is done, the weight measured by each scale may not be the same. This can be caused by one or both of the two scales being slightly out of calibration. This indicator has the ability to match any other scale, even if that scale is uncalibrated. To match your EZ scale (Scale A) to another scale (Scale B) you must determine the Calibration Multiplier. To do this, place a load on Scale A (feed wagon, etc...) and write down the weight displayed. Repeat several times to determine the average weight. Next, place the same load on Scale B and again write down the weight displayed. Again, repeat several times to determine the average weight. Then, use this formula to determine the Calibration Multiplier for the EZ's "CAL" number: It is important to use an average of several weights before calibrating the scale. Scale Matching Example: Original SETUP# CAL # trial 2 trial 3 trial Scale B 30,000 30,580 28,000 Scale A 29,440 29,800 27,500 B : A = : 3 trials = Cal. Multiplier New EZ CAL# = Orig. EZ CAL# x Cal Multiplier = x You should not modify your "SETUP" number. Only your "CAL" number.
