65 Series Rotary Tiller OPERATION TO THE NEW OPERATOR OR OWNER The Buhler Farm King 65 Series Rotary Tiller is a machine that combines the primary and secondary tillage operation into one machine. It breaks up the soil and prepares the seed bed in one pass. Rotational power to the rotor is provided by the tractor PTO. Be familiar with the machine before starting.
65 Series Rotary Tiller MACHINE BREAK-IN Although there are no operational restrictions on the Tiller when used for the first time, it is recommended that the following mechanical items be checked: A. After operating for 1/2 hour or after completing 1/2 acre: 1. Check all nuts, bolts and other fasteners. Tighten to their specified torque level. 2. Check that the blades are in good condition and bolted securely to the rotor. 3. Check the oil level in the gearbox. Add as required. 4.
65 Series Rotary Tiller EQUIPMENT MATCHING To insure the safe and reliable operation of the Tiller, it is necessary to use a tractor with the correct specifications. Use the following list as a guide in selecting a tractor to use on the machine. 1. Horsepower: Use Table 1 as a guide in selecting the tractor horsepower appropriate for your width of machine. Use only small Agricultural tractors on this machine. Table 1 Horsepower vs. Width Model 50H 60H 72H 82H Width 4.2 feet (1.3m) 5 feet (1.5m) 6 feet (1.
65 Series Rotary Tiller DRIVELINE DIMENSION A PTO driveline is supplied with the machine. To accommodate the variety of 3 point hitch geometry available today, the driveline can be too long for some machines and must be cut. It is very important that the driveline be free to telescope but not bottom out when going through its working range. If the driveline bottoms out, the bearings on both the machine and tractor PTO shaft will be overloaded and fail in a short time.
65 Series Rotary Tiller DRIVELINE DIMENSION – cont’d. 7. Pull the driveline apart and cut 1/2 of the dimension determined in step 5 from each end. Add another ½ inch (12MM) to each cut off segment. 8. Be sure to use a hacksaw to cut 1/2 from each end of the separated shaft. Cut both the plastic tube and the metal cores. Use a file to remove the burrs from the edges that were cut. Assemble the two ends of the shaft. Make sure that the shaft can telescope freely.
65 Series Rotary Tiller ATTACHING/UNHOOKING The Tiller should always be located on a level, dry area that is free of debris and other foreign objects. When attaching the machine to a tractor, follow this procedure: 1. Clear the area of bystanders, especially small children. 2. Be sure the tractor 3 point hitch is in the Category 1 configuration and the lift arms are in the non-sway configuration (See tractor manual). 3. Make sure there is enough room a nd clearance to safely back up to the Tiller. 4.
65 Series Rotary Tiller ATTACHING/UNHOOKING – cont’d. 9. Attach the PTO driveline: a. Check that the driveline telescopes easily and that the shield rotates freely. CAUTION: Be sure that the driveline does not bottom out when going through its working angles. b. c. Attach the driveline to the tractor by retracting the locking pin, slide the yoke over the shaft and push on the yoke until the lock pin clicks into position. Pull on the yoke to be sure it is locked in position.
65 Series Rotary Tiller FIELD OPERATION Buhler Farm King 65 Series Rotary Tillers are designed with the inherent flexibility of operating well in almost any kind of soil and terrain conditions. However, the operator has the responsibility of being familiar with all operating and safety procedures and following them. Each operator should review this section of the manual at the start of the season and as often as required to be familiar with the machine. When using, follow this procedure: 1.
65 Series Rotary Tiller FIELD OPERATION - cont'd. c. Offset: The Category Pin Brackets can be moved 3 to 4 inches along the Deck Assembly to either side of center if required. Center the machine for normal operation. Offset if the tire tracks are wider than the machine or when tilling around trees, bushes or other areas. ALERT: Sliding offset feature not available in the 82” model. d. Drag Shield: Adjust the chain in the Adjustment Bracket to set the height of the Drag Shield.
65 Series Rotary Tiller FIELD OPERATION - cont'd. 11. Operating hints: a. b. c. d. e. f. g. h. Determine the moisture content of the soil before starting. Soil that is too wet will "ball-up" in the rotor blades making tilling impossible. Sandy soils normally can be worked better than heavy clay or loam soils. It is the responsibility of the operator to determine the soil type and moisture content before starting. It may be necessary to wait for the soil to dry out before starting to work.
65 Series Rotary Tiller TRANSPORTING When transporting the machine, review and follow these instructions: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Be sure all bystanders are clear of the machine. Be sure that the machine is securely attached to the tractor and all retainer pins are installed. Clean the SMV emblem, lights and reflectors and be sure they are working. Be sure you are in compliance with all applicable lighting and marking regulations when transporting. Check with your local authorities.
65 Series Rotary Tiller STORAGE After the season's use, the machine should be thoroughly inspected and prepared for storage. Repair or replace any worn or damaged components to prevent any unnecessary down time at the start of next season. To insure a long, trouble free life, this procedure should be followed when preparing the unit for storage: 1. Clear the area of bystanders, especially small children. 2. Thoroughly wash the machine using a pressure washer to remove all dirt, mud, debris and residue.
65 Series Rotary Tiller SERVICE AND MAINTENANCE SERVICE Follow Maintenance Safety Instructions as outlined in Maintenance Safety. FLUIDS AND LUBRICANTS 1. Hydraulic Oil: Use standard hydraulic oil for all operating conditions. 2. Gear Box Oil: Use an SAE 85W90 gear oil for all operating conditions. Gear Box Capacity: 1 U.S. quart (0.85 liter) 3. Chain Case Grease: Use a multi purpose grease for all operating conditions. If chain case is removed, refill with 800 grams of grease. 4.
65 Series Rotary Tiller SERVICING INTERVALS The periods recommended below are based on normal operating conditions. Severe or unusual conditions may require more frequent lubrication or oil changes. 8 Hours or Daily; Telescoping Tubes and Quick Disconnect 20 Hours 1. Lubricate PTO driveline (7 locations). ALERT: When using the safety chains supplied with the PTO shaft, the shield bearings must be kept lubricated. 80 hours or once a season: 2. Lubricate rotor driven end Bearing (1 location) 3.
65 Series Rotary Tiller SERVICING INTERVALS – cont’d. 40 Hours 1. Check gearbox oil level. Add as required 2. Add approximately 10 squirts of grease in chain case. Annually 1. Change gear box oil. Refill with SAE 85W90 gear oil. 2. Wash machine.
65 Series Rotary Tiller MAINTENANCE By following a careful service and maintenance program for your machine, you will enjoy many years of trouble-free operation. A-FRAME ADJUSTMENT When moving the hitch along the front frame to adjust the offset, follow this procedure: 1. Clear the area of bystanders, especially small children. 2. Raise the machine so it is slightly out of the ground. 3. Loosen the U-bolts through the Category Pin brackets. 4.
65 Series Rotary Tiller SLIP CLUTCH During normal operation, the slip clutch can release and slip when encountering an obstruction or when overloaded. It is designed to slip when the load exceeds 3 times its nominal rating. When the clutch slips too frequently during normal operating conditions, it is necessary to replace the clutch linings. NOTE: The PTO shafts are shipped with the slip clutch disengaged.
65 Series Rotary Tiller CLUTCH MAINTENANCE 1. Before first use or after storage of more than one month, the clutch should be checked. 2. Disengage clutch by turning in the four socket set screws. 3. Run the PTO at low idle to slip the clutch linings. This will help remove the dirt, corrosion, and surface gloss from the clutch plates and also ensure that the linings are loose. 4. Engage the clutch by turning out the socket set screws. 5.
65 Series Rotary Tiller REPAIR MAIN SHAFT REPLACEMENT The main shaft is designed with a replaceable Final Drive Assembly on the driven end. This feature keeps the cost of repairs down should replacement be required and makes main shaft replacement easier. When replacing the Final Drive Assembly, follow this procedure; 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. Clear the area of bystanders, especially small children. Unhook from the tractor. Remove the driveline and store to the side.
