    ASSEMBLY INSTRUCTIONS F15B 16’6” – 24’0” The AMCO Fl5B Harrow is shipped from the factory with maximum pre-assembly. The following bundles are required for a complete harrow: A. Bundle Pull Tongue (with tongue jack) B. Bundle Main Frame (with rockshafts) C.
  • Page 45 Step 5. Attach the two front wing gang frames to the inside gang frames. Use the 1 ½" diameter wing pivot pins. Tighten the nuts snug but not tight. CAUTION: When working on disk harrows care should be exercised in handling or tightening bolts near disk blades to avoid injury.
  • Page 46 Step 8. Clamp the wing main frames to the wing gang frames using the 7/8 x 9 bolts and 5/8 x 3 straps. Shift gangs as required to align all holes. Thoroughly tighten all thirty-two 7/8 x 9 clamp bolts. Tighten four 1 ½"...
  • Page 47 CAUTION: When working on disk harrows, care should be exercised in handling or tightening bolts near disk blades to avoid injury. 16'6", 18'0" & 19’6” 21'0" AND 24'0" WING MAIN FRAME WING MAIN FRAME TURNBUCKLES HYDRAULIC CYLINDER MOUNTING Step 10. Adjust turnbuckles to 15"...
  • Page 48 Step 11. Install the two 4" x 8" hydraulic cylinders on the center main frame and the two center rockshafts. The rod end should be attached to the rockshaft. The two 1-1/4" cut washers should be installed between the transport lock and cylinder clevis. Step 12.
  • Page 50 Step 14. Install hydraulic fittings as follows: Note: Remember the right and left hand sides of the plow are determined by standing at the rear of the plow and facing the direction of travel. A. Install four #12180 ½" Male to ½" Female swivel elbows into the ports on the 4" x 8" cylinders.
  • Page 51 Step 16. Attach four ½" x 10" or 3/8" x 10" SAE 100R2 or SAE 100R8 Double Braid Hydraulic hoses to the swivel adaptors on the main frame. Attach quick couplers. Attach hoses to tractor. Step 17. Install Light Kit and SMV Emblem Ref No.
  • Page 53 Step 18. Final Grooming and Check Points. A. Check inside front gangs. They should overlap in center about 1-1/2" to 2-1/2". (Front tips inside blades should be 3/4" to 1-1/4" over center line of harrow.) This can be adjusted by shifting the gang frames.
  • Page 54 (5) Check decals to be certain they are in place and in good condition. Touch up paint as required before delivery. Place Operators Manual in the heavy plastic shipping bag and place securely back into Manual Tube bolted to the Main Frame. K.

  • Page 55: Lubrication

    Lubrication Careful and regular attention to lubrication will greatly increase the life of the harrow. For economical and efficient operation, the proper lubrication of frame fittings, gang bearings, and wheel bearings is essential. Be sure fittings are free of dirt before greasing. If a fitting is lost or damaged, replace it immediately.
  • Page 56 GANG BEARINGS: The AMCO F15B Harrow Gangs are equipped Maintenance-Free bearings. No lubrication needed. Bearings come with 3-year manufacturer warranty. WHEEL HUB BEARINGS: The wheel hubs are equipped with tapered roller bearings. These hubs are packed with grease and adjusted at the factory. They should be repacked and the spindle nut properly adjusted each disking season or every 300 hours of operation.
  • Page 57 WING PIVOT PINS: The hydraulically folded wings pivot on four 1-1/2" diameter high carbon steel pins. These pivot pins should be greased each week or every 50 hours of operation. CAUTION: All hydraulically or mechanically elevated operating components must be blocked to prevent accidental lowering or must be lowered to the ground when making adjustments or when the equipment is idle.

  • Page 58: Storage

    Storage Proper storage will add to the life of your disk harrow, and assure its being in good condition for the next season. The following procedure is recommended. Clean off all foreign matter, and thoroughly lubricate the harrow. (See LUBRICATION INSTRUCTIONS) Tighten loose bolts and replace and damaged or missing parts.

  • Page 59: Maintenance

    Maintenance WHEEL BEARING REPAIR: Wheel bearings should be repacked with grease and adjusted annually. Under extreme conditions, they should be serviced more frequently. Check occasionally for excessive end play. To disassemble the hub, remove the dust cap by prying around it. Remove the cotter pin, slotted nut and flat washer.
  • Page 60 6. Spindle washer, slotted nut, cotter pin and hub cap must be in good condition. Replace if worn or damaged. 7. To reassemble the hub, repack each bearing cone with grease and fill the hub cavity 1/3 full of grease. Place inner bearing assembly in hub, press seal into the hub and carefully re-install the hub on the spindle.
  • Page 61 This hole must align with the grease groove in the bearing housing. Rotate the bearing in the housing after it is pressed in to be sure it turns freely. Install the snap ring in the housing. 13. After cleaning, checking and replacing all damaged parts, the gang should be assembled. Be sure the grease fittings in the bearing housing face to the rear.
  • Page 62 D. Carefully clean and inspect all parts for wear or damage. Small nicks, scratches or blemishes on rod and inside of barrel should be smoothed with fine steel wool or emery cloth. Replace parts that cannot be repaired. E. Remove all O' Rings from piston and gland. Replace all seals with new parts. F.

  • Page 63: Operating Instructions

    Operating Instructions TRANSPORTING THE DISK: Extreme caution is required when transporting and machinery on roads or highways. Remember you are responsible for compliance with State and Local laws regarding lighting, reflectors, and SMV emblems as well as length and width. CAUTION: When transporting farm implements on public roads after dusk, it is the responsibility of the operator to provide lighting and reflectors on the rear of the implements in accordance with your state law.
  • Page 64 Each of the 4" x 8" hydraulic cylinders used for lifting the F15B is equipped with a transport latch. When the harrow is on its wheels in the transport position, these latches may be folded over the cylinder rods preventing the cylinders retracting. These latches should always be used when the harrow is transported.
  • Page 65 SUMMARY: The F15B has three primary adjustments that can be used to "set" the disk for proper operation. They are (1) stroke control on the lift cylinders (2) turnbuckles to control wing cutting depth and (3) tongue adjusting rod to level the disk front to rear.

  • Page 66: Operating Tips

    5. Wash corrosive materials such as fertilizer and herbicides from the disk when it is not in use. 6. Insist on genuine AMCO replacement parts. Items such as bearings and blades look alike but are not as reliable as original equipment.

  • Page 67: Disk Blade Failure

    MOST OFTEN ENCOUNTERED DISK BLADE FAILURES Most disk blade failures can be prevented by selecting, the correct blade size and thickness for individual conditions When buying disk. Reduction of speed in areas containing rocks and stumps will greatly lengthen the blade life. Keeping gang bolts properly torqued and raising the harrow while turning will also reduce disk blade breakage.
