2. Installaon & Set-Up
Safety: Ensure tractor and machine is staonary and keys out of ignion before set-up/maintenance.
Safety: Make sure the PTO drive is not connected at any point unl instructed to do so.
You will need:
Your tractor, tractor top link arm (adjustable), linkage pins, PTO sha.
Aaching The Mower
Start by nding a at piece of ground. Lower the three point linkage on your tractor to its lowest
posion and aach the rotovator to the tractor using the three point linkage pins and linch pins.
Adjust the top linkage arm on the tractor to line-up with the rotovator, aach using the top link pin
and linch pin.
Adjust the length of the top linkage arm unl the rotovator’s PTO output is parallel to the ground. Start
the tractor engine and li the rotovator from the ground. Then switch o the tractor engine and
remove the ignion key.
Level the rotovator so both sides are parallel to the ground by adjusng the tractor’s liing arms. The
blades must be at equal distance from the ground on both sides of the rotovator.
Adjust the tractor lower link arm to prevent excessive movement to the side (we recommend a
movement of 5cm each side).
Aach the PTO driveline and check it correctly meshes at both ends. If a shear bolt or slip clutch safety
system is used on the PTO sha, this must be mounted on the rotovator end. Check the PTO driveline
is the correct length. The minimum overlap must be 18cm when working, and the driveline must be
able to travel at least 2.5cm.
Always couple the two ends of the driveline and check they are locked in place. Completely insert the
sprung lock pins into the grooves in the PTO sha on both the tractor and rotovator sides. Check an
apply grease if required to grease points on PTO sha. Aach the PTO drive sha, secure locking pin,
and ensure chain is aached to a secure point.
Operate the ail mower the with tractor in low range gear and the PTO delivering 540 RPM.
Pre-Mowing Checklist
Before starng the machine, always check and adjust the following:
• Blades are ed correctly. [Secon 4]
• Oil level of the gearbox. [Secon 5 & 6]
• Rear guard is correctly adjusted [Secon 7]
• Tilling depth is correctly adjusted [Secon 8]
• Tightness of all bolts, nuts and screws.
• All protecve guards are in place and storage stands are removed.

3. Operang Advice
Safety: Ensure tractor and machine is staonary and keys out of ignion before set-up/maintenance.
Safety: Before aaching/detaching machinery ensure the hydraulic li system is in a neutral posion.
Lower the tractor li arms unl the blades are just above the ground’s surface, and engage the PTO
drive to a speed of 540 rpm. Then connue lowering the blades to gradually cut into the soil.
When the rotovator is working the soil move slowly at a speed of 1 to 3 mph in a low gear range. The
recommended working depth for so soil is 15cm, and 13cm for dense/dry soils. (To adjust the
working depth see page 13). Check the results aer working the soil a few metres, and make any
adjustments. Keep the worked soil to the driver’s right side.
When turning, always raise the rotovator from the soil (no more than 25cm when the PTO driveline is
engaged, as this can cause damage). 20° is the maximum angle with the PTO driveline engaged. A
greater angle can cause strong vibraons/damage to the rotovator.
The rotovator is not suitable for very stony soils, this can damage the blades/machine and void the
warranty. Take care on sloped areas, work at a slow speed and upwards (or downwards) rather than
across the gradient to reduce the risk of overturning. Never operate on wet, slippery grass/soil or
where the tyres are struggling to grip.

4. Blade Replacement
Safety: Ensure tractor and machine is staonary and keys out of ignion before set-up/maintenance.
Note: Clearance of blades to the ground should be at least 50mm and higher on uneven ground.
Li the machine to access the blades and rotor. Use rigid supports and ensure the rotovator is stable.
Replace any damaged/worn/blunt blades:
1. Unscrew the 2x bolts and nuts (1) and remove the blade.
2. Insert the replacement blade (2). Ensure the blades on the same blade mounng are bolted on
alternate sides (le-handed to one side then right-handed to the other) as shown in the image.
3. Replace bolts and nuts (1).
4. Check all blade bolts are secured and blades are adjusted correctly.
5. Run the rotovator for 5-10 minutes and re-check bolt ghtness.

5. Gearbox Oil Check & Change
Safety: Ensure tractor and machine is staonary and keys out of ignion before set-up/maintenance.
Always check oil when the machine has cooled down and on a level surface. Make sure bolts are
ghtened correctly. The ller/level plug should be secure but not over ghtened.
Do not mix old and new oils together, or mix dierent oil types. Always dispose of oils correctly and
safely. Aer use, the aachment should be le to cool down for 15 minutes before checking oil levels.
Ensure the gearbox is at/level when checking oil levels. Always follow manufacturer’s instrucons for
oils and lubricants.
Important Informaon
1.Remove level plug (1) and breather/ller plug (2).
2.The oil level should be up to the edge of level plug (1) approximately half full. If required, top up with
oil using ller hole (2).
3.Replace both plugs (1 & 2).
If draining and replacing oil, then remove drain plug (3) and let the oil drain out. Replace drain plug (3)
then replace oil as above.

6. Gear Reservoir Oil Change
Safety: Ensure tractor and machine is staonary and keys out of ignion before set-up/maintenance.
Always check oil when the machine has cooled down and on a level surface. Make sure bolts are
ghtened correctly. The ller/level plug should be secure but not over ghtened.
Do not mix old and new oils together, or mix dierent oil types. Always dispose of oils correctly and
safely. Aer use, the aachment should be le to cool down for 15 minutes before checking oil lev-
els. Ensure the gearbox is at/level when checking oil levels. Always follow manufacturer’s instruc-
ons for oils and lubricants.
1. Remove breather/ller plug (4) and drain plug (5) to allow the oil to drain from the reservoir.
2. Replace and screw in drain plug (5), replace oil using a funnel through ller hole (4).

7. Rear Guard Adjustment
Safety: Ensure tractor and machine is staonary and keys out of ignion before set-up/maintenance.
To determine how compacted the soil is aer culvang, adjust the rear guard using an adjustment
rod. The rod is sprung so there is downwards force on the rear panel to aid compacon.
1. Remove R clips (1 & 2).
2. Move both R clip (1) up or down and insert into one of the holes (3).
3. Move R clip (2) up or down the same number of holes into (4).
4. Ensure the springs remain between the two R clips (1 & 2).

8. Tilling Depth Adjustment
Safety: Ensure tractor and machine is staonary and keys out of ignion before set-up/maintenance.
We recommend a maximum working depth of 15cm for so soil, and 13cm for dense/dry soils.
The inial set up of the tractor’s top linkage arm and the linkage set up will inuence lling. But it is
also important to set up the side skids to get the correct depth when culvang.
Moving the skids down and further away from the body will create a shallower working depth. Moving
the skids upwards closer to the machine will increase the working depth achieved.
1.Remove bolt (5) and loosen o bolts (6).
2.Replace bolt (5) into the selected hole (7) and ghten.
3.Re-ghten bolts (6) in posion.
4.Repeat steps (1-4) above on the other side of the machine.

9. Servicing & Maintenance
Safety: Store all lubricants away from excessive heat, dust, moisture and contaminants.
Safety: Ensure tractor and machine is staonary and keys out of ignion before set-up/maintenance.
Greasing & Lubricaon Points
1. Bearings on the blade rotor x2
2. Bearings on the rear roller x2
3. PTO sha x2
4. Body arm x4
Wipe grease nipples with a clean cloth before greasing to avoid injecng any dirt or grit. Press grease
into each grease nipple three to ve mes. We recommend using a hand-held grease gun for best
results.
If grease nipples will not take grease, remove and clean thoroughly. Also clean lubricant passageway.
If you noce any grease points are broken replace or repair them immediately.
Other Maintenance
Blades: Check condion of the blades and replace if worn/broken. Always take care when handling
blades, wear gloves and use suitable tools for changing blades. If blades are replaced check they are
balanced in order to avoid any excessive vibraon.
Oils: Ensure oil levels are checked and topped up when needed. Replace any oils per the schedule.
PTO Sha: Check the condion of your PTO sha and replace if worn or damaged immediately.
Cleaning: Ensure the mower deck and blades are cleaned of mud/grass. Remove debris is from
moving parts to prevent entanglement. Do not spray bearings with a high pressure washer when
cleaning .
Bearings: Check the bearings on the blade rotor and the rear roller. If the oil seals are damaged
debris may enter the bearings. Clean and replace with new bearings if necessary. Run the mower
without a load for 3-5 minutes to check bearings are operang smoothly.
Paintwork: Re-coat any damaged paintwork to prevent corrosion.
Store the machine in a dry, level area and ensure it is stable and unable to move or overturn.
Skids: Check the condion of the side skids and replace if worn.
*The periods recommended are based on normal operang condions. Severe or unusual condions
may require more frequent maintenance.

PTO Sha Resizing
Safety: Ensure tractor & machine is staonary and keys out of ignion before carrying out any work. If
you are not condent in carrying out the work consult your local supplier or mechanic.
Most PTO driven implements are supplied with a standard sized PTO sha. As all tractors vary this
oen means cung it down to size. Always replace worn or damaged PTO shas.
Aach the machine to the tractor without the PTO sha, raise the linkage so the PTO sha is level/
horizontal. Measure the length between tractor PTO and the machine’s sha. If the compressed
(closed) PTO sha length exceeds the one measured here then the driveline will need to be cut.
1. PTO length adjustment, rst remove PTO sha shielding.
2. Shorten the driveline tubes to proper equal lengths.
3. Tidy edges of the drive tube with a le and clean all llings from the tubes.
4. Shorten the equally long guard tubes to the same length as the driveline tubes.
5. Grease the internal driveline tube.
6. Fit the guard on the sha.
7. Make sure that the length allows for at least 16cm (6 inches) of overlap.
