STEP 11. Final Grooming and check points. A. Check inside front gangs. They should overlap in the center about 2-1/2" to 3-1/2". (Front tips of inside blades should be 1-1/2" to 2" over center line of harrow.) This can be adjusted by shifting the gangs on the gang frames. It is important that center blades clear by at least 3/4".
WARNING Lower or block elevated components before servicing or when leaving the machine. Elevated components can fall and cause serious injury. GANG BEARINGS The AMCO F17 Harrow Gangs are equipped Maintenance-Free bearings. No lubrication needed. Bearings come with 3-year manufacturer warranty.

TONGUE ADJUSTING ROD: The two swivels on the tongue adjusting rod should be greased every 50 hours of operation, also, at the beginning and end of each disking season. The threads on the rod should be cleaned and oiled occasionally for smooth operation. WHEEL HUB BEARINGS The wheel hubs are equipped with tapered roller bearings.
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. Adjust as required to eliminate excessive end play. To disassemble the hub, remove the dust cap by prying around it. Remove the cotter pin, slotted nut and spindle washer.
Page 33
5. Threads on spindle must be in good condition. Bearing cone seats must be smooth and free of blemishes. Bearing cones must fit squarely on spindle. 6. Spindle washer, slotted nut, cotter pin and hub cap must be in good condition. Replace if worn or damaged.

against the outer race of the bearing. Rotate the bearing in the housing after it is pressed in to be sure it turns freely. Install the snap ring in the housing. 12. Check all disk blades for cracks, breaks, wear and other damage. Replace worn or damaged disk blades.
GENERAL Keep all bolts tight, Check all bolts after 50 hours operation and each season thereafter. Visually inspect all bogs daily. DO NOT run with loose gang bolts. Keep the gang bolts torqued to 1200 ft. lbs. STORAGE Proper storage will add to the life of your disk harrow, and assure its being in good condition for the next season.
Disk as deep as necessary to do a thorough job, but do not try to disk to an excessive depth. In most conditions the AMCO harrow has sufficient weight for good penetration, in other conditions you have a little more weight than you really need. For these conditions, your harrow should be equipped with flotation tires.
Page 37
TRACTOR SPEED Speeds above 6 MPH may result in forming ridges and furrows. Lateral adjustment of the rear gangs and reducing gang angle helps overcome this problem. CAUTION: When adjusting gang angle make sure the 7/8" gang frame mount bolts are torqued properly before use, Refer to the torque chart on page 17.
Page 38
The transport pin should be used to secure the disk in the raised posi- tion. The transport pin must be secured in place. Remove Transport pin before use in working position. When the disk is in use or being transported. The tongue jack should be stored on the tongue. This will prevent loss of the gang bolt wrench and damage to the tongue jack.
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.
MOST OFTEN ENCOUNTERED DISC BLADE FAILUIRES Most disk blade failures can be prevented by selecting the correct blade sizer and thickness for individual conditions when buying a disk, Reduction of gang cutting angle and 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.
