Start up
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:
· After operating for 1/2 hour or after completing 1/2 acre: – Check all nuts, bolts and other fasteners. Tighten to their specified torque level. – Check that the blades are in good condition and bolted securely to the rotor. – Check the oil level in the gearbox. Add as required. – Check that the PTO driveline shield turns freely. – Lubricate all grease points. · After operating for 5 hours and 10 hours: – Repeat the items above. – Then go to the regular service schedule as defined in Section 5.
Pre-operation Checklist
Efficient and safe operation of the Rotary Tiller requires that each operator reads and understands the operating procedures and all related safety precautions outlined in this section. A pre-operation checklist is provided for the operator. It is important for both personal safety and maintaining the good mechanical condition of the Tiller that this checklist is followed.
· Before operating the machine and each time thereafter, the following areas should be checked off:
Lubricate the machine per the schedule outlined in the Service and Maintenance Section. Use only a tractor of adequate power and weight to pull the machine. Check that the machine is properly attached to the tractor. Be sure retainers are used on the mounting pins. Check the oil level in the gearbox. Add as required. Check that the PTO driveline shield turns freely and that the driveline can telescope easily. Clean and lubricate if required. Check the blades. Be sure they are not damaged or broken and are bolted securely to the rotor. Repair or replace as required. Remove any entangled material on rotating parts. Install and secure all guards, doors and covers before starting. The four socket set screws on the inside of the PTO clutchassembly must be turned

Operation Instruction
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:Do not exceed the recommended horsepower levels.Use only small Agricultural tractors on this machine. 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.
Shortening a PTO Driveline
1. With the implement attached to the tractor’s three point hitch, and the PTO driveline not installed, separate the PTO driveline. Attach the implement end to the implement and the other end to the tractor PTO input shaft. 2. Raise the implement by using the tractor’s hydraulic 3-point hitch to it’s maximum lift height. 3. Hold the half shafts next to each other and mark them so each end is approximately ½” from hitting the end of the telescopic profiles. 4. Shorten the inner and out guard tubes equally. 5. Shorten the inner and outer profiles by the same length as the guard tubes. Using a rat tail file, round off all sharp edges and burrs. Grease the telescopic profile generously before reassembling.

Operation Instruction
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. Attach the PTO driveline to the Tiller if it was removed for storage (See Assembly). 5. While backing up, align the lift arm balls with the mounting pins on the Tiller.
6. Stop tractor, set park brake, remove ignition key and wait for all moving parts to stop before dismounting.
7. If your tractor is not equipped with a Quick Hitch: — Align the left lower link arm with the mounting pin. — Slide the ball over the pin and install the Linch Pin. — Use the screw jack on the right lift arm to align the ball with the pin. — Slide the ball over the mounting pin and install the Linch Pin. — Level the frame using the screw jack. — Remove the retainer and pin — Insert pin and install Linch Pin. — Level frame using the turnbuckle.
8.Use the 3-point hitch to raise the machine.
