IMPORTANT

1. Operator should be familiar with all functions of the unit.
2. Make sure all guards and shields are in place and secured before operating implement.
3. Keep all persons away from equipment and work area.
4. Dismounting from a moving unit can cause serious injury or death.
5. Keep hands, feet, and clothing away from power-driven parts.
6. Detach and store implement in an area where children normally do not play. Secure implement by using blocks and supports.

Always wear proper safety glasses, goggles, or a face shield when driving pins in or out, or when any operation causes dust, flying debris, or any other hazardous material.
Operator Safety
►Wear protective clothing and equipment appropriate for the job. Clothing should be snug fitting without fringes and pull strings to avoid entanglement with moving parts.
►Prolonged exposure to loud noise can cause hearing impairment or hearing loss. Wear suitable hearing protection such as earmuffs or earplugs.
►Operating equipment safely requires the operators all attention, Avoid wearing radio headphones while operating machinery.
Tool Safety
►Inspect entire machine before each use. Replace damaged or worn parts.
►Check for fuel leaks and make sure all fasteners are in place and securely fastened.
Maintenance Safety
►Maintain according to recommended procedures included in this manual.
►Disconnected the spark plug wire before performing maintenance.
►Stop engine before removing fuel cap.
►Use only genuine replacement parts of the engine manufacturer.

Wear Protective Equipment

►Escaping fluid under pressure can penetrate the skin causing serious injury.
►Avoid the hazard by relieving pressure before disconnecting hydraulic lines or performing work on the system.
►Make sure all hydraulic fluid connections are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system.
►Use a piece of paper or cardboard, NOT BODY PARTS to check for suspected leaks.
►Wear protective gloves and safety glasses or goggles when working with hydraulic systems.
►DO NOT DELAY. If an accident occurs, see a doctor familiar with this type of injury immediately. Any fluid injected into the skin or eyes must be treated within a few hours or gangrene may result.
Transportation and Storing

OPERATION INSTRUCTIONS

** Check the unit before attaching the rotary tiller to the tractor to ensure there is oil in the top and side gear box. See Maintenance section for lubricant specifications.
Check the oil grease points before starting operation
Oil level: Top gearbox 1 1/2” from the end of the dip stick. When sitting slightly tilted forward, oil should at the bottom of the fill plug on the side gearbox cover.
Grease: Right Rotor bearing, PTO shaft Cross & Bearings
Attaching to the tractor**

1. With the Rotary Tiller on a level surface, back the Cat. 1 tractor so the tractor lift arms are even with the unit’s lower hitch pins. Lower or raise the tractor hitch arms until the 7/8” bushing in the arm is inside the clevis of lower hitch points. Be sure nothing is between the tractor and the tiller before backing up.
2. Insert the lower hitch pin through the lower hitch blocks and the tractor arm. The YCT series tillers have adjustable lower hitch blocks that can be slide to facilitate usage on larger tractors.
3. Secure the lift arm in place by using a 7/16” lynch pin or other fastener.
4. Repeat with the other arm.
5. Connect the driveline to the tractor’s PTO output shaft. Secure it in place.
6. Connect the tractor top link to the upper hitch point of the rotary tiller.
7. Start the tractor and slowly raise the tiller. Check for drawbar interference. Be sure that the PTO driveline does not bottom out when lifting the machine to it’s maximum height. If it does appear that it could bottom out, it is necessary to shorten the PTO driveline. (See Shortening a PTO Driveline section). Ensure that in the working position there is an overlap of a minimum of 1/3 the length of each profile.

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.

** Do not shorten too much, the proper overlap is a minimum of 1/3 the length of each profile.
Caution: Slip Clutches may get hot. Do Not Touch. Keep the slip clutch area clear of an material that may catch fire.
Slip clutches have adjustable torque settings. The torque setting varies with the different compression of each spring. All the springs should have an equal amount of compression.
IMPORTANT: Do not over-tighten the compression nuts as this may impair performance or cause premature wearing of the slip clutch.
Slip Clutch adjustments**

1. Using a marker, scribe a line across the exposed edges of the clutch plate and friction discs.
2. Back off compression nuts to free friction discs by turning each nut exactly 2 revolutions.
3. Start the tractor and run the driveline at a low idle to slip the friction discs. This will remove the dirt, corrosion and surface floss from the clutch plate faces.
4. Disengage PTO, shut down the tractor and wait for all components to come to a complete stop.
5. Inspect the clutch and ensure that the scribed markings on the disc and plates have changed position. If any two marks are still aligned, this is an indication that these discs have not slipped. It may need to completely disassemble the clutch to free them up.
6. After ensuring all discs are free, tighten the compression nuts, uniformly, exactly 2 revolutions to resent the clutch original pressure.

Working Depth Adjustment
The working depth is controlled by raising or lowering the side skids. If the skids are raised, the working depth increases. By lowering the skids, the tilling depth with decrease.
Tailgate adjustment
The tailgate can be adjusted to help smooth and compact the tilled ground. Release the chain and secure to the desired height.

Start up
After making the necessary adjustments, lower the rotary tiller until the blades are a couple of inches from the ground. Engage the PTO and slowly lower the tiller to begin working.
Removal and Storage
After finishing, remove the rotary tiller from the tractor.

1. Put the PTO driveline in a safe location to avoid damage.
2. Clean and dry the equipment.
3. Replace any damaged or worn parts.
4. Check all bolts and nuts for tightness.
5. Lubricate and protect the machine from the elements.
