25 Series Rotary Tiller OPERATION TO THE NEW OPERATOR OR OWNER The Buhler Farm King 25 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. It is the responsibility of the owner or operator to read this manual and to train all other operators before they start working with the machine.
25 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.
25 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 40S 48S 60S Width 40 inches (1.0m) 4 feet (1.3m) 5 feet (1.
25 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.
25 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.
25 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 and clearance to safely back up to the Tiller. 4.
