Introduction - 25 Series Rotary Tiller
Introduction
Farm King has a collection of rotary tiller models to suit your garden and landscaping needs. The 25 Series Tiller attaches to the 3-point hitch as well as our Cat. 1 Quick Hitch and is designed to fit a variety of tractors from 12 hp to 25 hp. Tilling widths range from 36" to 54" in the 25 Series.
The tilling shaft is equipped with four to six flanges, depending on the model. Flanges on all series are available with four tines. This provides an optimum balance between performance and durability, even in heavy soils and when breaking untilled soil.
Standard on all Farm King Rotary Tillers, the skid shoes are adjustable so it is easy to set the perfect tilling depth. The automatic chain tightener is standard on all models. This ensures the chain remains tight even under the toughest tilling conditions. Housing within a sealed oil bath, the chain tightener is designed to be reliable and maintenance-free. Getting close to the fences, hedges or covering a tire track is easy with the side shift feature. The entire unit can be pushed to one side, while the PTO shaft remains in line with the tractor to minimize stress on the universal joint. The side shift feature is available on all 25 Series Farm King Rotary Tillers.
Keep this manual handy for frequent reference. All new operators or owners must review the manual before using the equipment and at least annually thereafter. Contact your Farm King Dealer if you need assistance, information, or additional copies of the manual. Visit our website at www.buhlerindustries.com for a complete list of dealers in your area.
The directions left, right, front and rear, as mentioned throughout this manual, are as seen facing in the direction of travel of the implement.

Operation - 25 Series Rotary Tiller
Operation Instructions
The 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.
NOTE: 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 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.

Operation - 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 Width Horsepower
40S 3.3 ft (1.0 m) 18
48S 4 ft (1.3 m) 22
60S 5 ft (1.5 m) 25
ALERT
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.
Do not exceed the recommended horsepower levels. The use of horsepower will void the warranty.

Operation - 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.
If cutting the drive is necessary, 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 gearbox 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 pin to pin dimension (B) exceeds the groove to groove dimension, the driveline should be cut.
7. Pull the driveline apart and cut 1/2 of the dimension determined in step 5 from each end. Add another 1/2" (12mm) to each cut off segment.
