Resumen del manual
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. Follow all safety instructions exactly. Safety is everyone's business. By following recommended procedures, a safe working environment is provided for the operator, bystanders and the area around the work site. Untrained operators are not qualified to operate the machine. Many features incorporated into this machine are the result of suggestions made by customers like you. Read this manual carefully to learn how to operate the machine safely and how to set it to provide maximum field efficiency. By following the operating instructions in conjunction with a good maintenance program, your Tiller will provide many years of trouble-free service. MACHINE COMPONENTS The Buhler Farm King 25 Series Rotary Tiller consists of a rotating drum that is equipped with bent blades for breaking up and leveling soil. The blades are turned through the soil while the machine moves over the working area. A Drag Shield is used to maintain a level seedbed. Rotational power to the drum is provided by the PTO on the tractor. The power is transmitted through the gearbox in the center of the machine to the chain drive down the side. The A-frame can be moved to offset the machine.

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 Width Horsepower 40S48S60S 40 inches (1.0m) 4 feet (1.3m) 5 feet (1.5m) 182225 ALERT: Do not exceed the recommended horsepower levels. The use of horsepower will void the warranty. 2. 3 Point Hitch: The Tiller is equipped with a Category 1, 3 point hitch. Be sure the tractor 3 point hitch is in the Category 1 configuration. Install the lift arm blocks or shorten the stop chains to place the arms into the non-sway configuration. Refer to the tractor manual for details. 3. Load Sensing Hydraulics: Many newer tractors are equipped with "Load Sensing" hydraulics. It is the responsibility of the operator to set the tractor hydraulic system to provide "float" on the 3 point hitch. The float feature will allow the machine to follow the ground contours during operation. 4. PTO Shaft: The tractor must have a 1 3/8" 6 spline 540 RPM PTO shaft to fit the driveline shaft supplied with the machine. Do not use shaft adapters or operate at any other speed. It is not recommended that a tractor with variable speed PTO's be used on the Tiller. Operating at speeds faster than 540 RPM will overload the drivetrain and lead to early failures. Attach the safety chains supplied with the PTO shaft, allowing sufficient slack for the Driveline during turns and operation. Check booklet attached to the PTO for instructions. 10 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. When cutting the driveline, follow this procedure: 1. Clear the area of bystanders, especially small children. 2. Attach the Tiller to the tractor but do not attach the driveline. 3. Raise the machine until the input shaft is level with the tractor PTO shaft. 4. Measure the dimension between the locking groove on the tractor PTO shaft and the groove on the Tiller input shaft. 5. Measure the same dimensions on the compressed driveline. 6. If the driveline dimension exceeds the machine dimension, the driveline will have to be cut. 11 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 . 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. 9. Use a file to remove the burrs from the edges that were cut. 10. Assemble the two ends of the shaft. 11. Make sure that the shaft can telescope freely. If it does not, separate the two parts and inspect for burrs or cuttings on the shaft ends. Be sure it telescopes freely before installing. 12. Make sure the plastic ...
