OPERATION INSTRUCTIONS

Check the unit before attaching the rotary tiller to the tractor to ensure thereis oil inthe top and side gear box. See Maintenance section for lubricant specifications.

Check the oil grease points before starting operationOil 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 gearboxcover. 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 PTOdriveline 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 PTODriveline section). Ensure that in the working position there is an overlap of a minimumof 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 minimumof 1/3 thelength of each profile.

OPERATION INSTRUCTIONS

Caution: Slip Clutches may get hot. Do Not Touch. Keep the slip clutchareaclear 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 causepremature 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 needtocompletely disassemble the clutch to free them up.
6. After ensuring all discs are free, tighten the compression nuts, uniformly, exactly 2 revolutions to resent theclutch original pressure

Working Depth Adjustment

The working depth is controlled by raising or lowering the side skids. If the skids are raised, the workingdepth 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
