Before installation/maintenance, ensure both tractor and
attachment are stationary, with the hydraulic lift system in a neutral
position and the ignition key removed.
1. Position the tractor on at ground and lower the 3-point linkage (3) to
line-up with the rotovator. Attach the rotovator using 3-point linkage
pins (1), and x in place with linch pins (2).
2. Adjust the top linkage arm on the tractor (12) to line-up with the
rotovator, attach using the top link pin and linch pin (11).
3. Adjust the length of the top linkage arm until the rotovator’s PTO
output is parallel to the ground. Start the tractor engine and lift the
rotovator from the ground. Then switch o the tractor engine and
remove the ignition key.
4. Level the rotovator so both sides are parallel to the ground by
adjusting the tractor’s lifting arms. The blades must be at equal
distance from the ground on both sides of the rotovator.
5. Adjust the tractor lower link arm (13) to prevent excessive movement
to the side (we recommend a movement of 5cm each side).
Installation
6. Attach 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 shaft,
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.
8
Installation (Continued)
Always couple the two ends of the driveline and check they are locked in
place. Completely insert the sprung lock pins (1) into the grooves in the
PTO shaft on both the tractor and rotovator sides. Check an apply grease if
required to grease points on PTO shaft. Attach the PTO drive shaft, secure
locking pin, and ensure chain is attached to a secure point.
Operating Instructions
Lower the tractor lift arms until the blades are just above the ground’s
surface, and engage the PTO drive to a speed of 540 rpm. Then continue
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 soft soil is
15cm, and 13cm for dense/dry soils. (To adjust the working depth see
page 13). Check the results after 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 vibrations/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.

9
Blade Replacement
Before installation/maintenance, ensure both tractor and attachment
are stationary, with the hydraulic lift system in a neutral position and
the ignition key removed. Take care when handling blades, wear
gloves and use suitable tools.
Lift 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
mounting are bolted on alternate sides (left-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 tightness.

10
Gearbox Oil Change & Check
Before installation/maintenance, ensure both tractor and
attachment are stationary, with the hydraulic lift system in a neutral
position and the ignition key removed.
Do not mix old and new oils together, or mix dierent oil types. Always
dispose of oils correctly and safely. After use, the attachment should be
left to cool down for 15 minutes before checking oil levels. Ensure the
gearbox is at/level when checking oil levels. Always follow manufacturer’s
instructions for oils and lubricants.
Gear Oil Grade 80w90 gear oil (or equivalent)
Gearbox Oil Level Approx. 1.75 litres to level plug
First Oil Change 50 hours use
Oil Change Frequency 250 hours/yearly (whichever is rst)
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) and (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.

Gear Reservoir Oil Change
Before installation/maintenance, ensure both tractor and
attachment are stationary, with the hydraulic lift system in a neutral
position and the ignition key removed.
Ensure the reservoir has sucient oil to allow grease to the lower gear,
which will then work its way up the gears when operating. Do not mix old
and new oils together, or mix dierent oil types. Always dispose of oils
correctly and safely.
After use, the attachment should be left to cool down for 15 minutes
before checking oil levels. Ensure the gearbox is at/level when checking
oil levels. Always follow manufacturer’s instructions for oils and lubricants.
Gear Reservoir Oil Grade: SAE140 gear oil (or equivalent) by condition
Reservoir Oil Level: Approx. 2 litres
First Oil Change 50 hours use
Oil Change Frequency 250 hours/yearly (whichever is rst)

Remove breather/ller plug (4) and drain plug (5) to allow the oil to drain
from the reservoir. Replace and screw in drain plug (5), replace oil using a
funnel through ller hole (4). Replace breather/ller plug (4).
12
Rear Guard Adjustment
Before installation/maintenance, ensure both tractor and
attachment are stationary, with the hydraulic lift system in a neutral
position and the ignition key removed.
To determine how compacted the soil is after cultivating, adjust the rear
guard using an adjustment rod. The rod is sprung so there is downwards
force on the rear panel to aid compaction.
Remove R clips (1) and (2). Move both R clip 1 up or down and insert into
one of the holes (3). Move R clip (2) up or down the same number of holes
into (4). Ensure the springs remain between the two R clips.

Tilling Depth Adjustment
Before installation/maintenance, ensure both tractor and
attachment are stationary, with the hydraulic lift system in a
neutral position and the ignition key removed.
We recommend a maximum working depth of 15cm for soft soil, and
13cm for dense/dry soils.
The initial set up of the tractor’s top linkage arm and the linkage set up
will inuence tilling. But it is also important to set up the side skids to get
the correct depth when cultivating.
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 tighten.
3. Re-tighten bolts (6) in position.
4. Repeat steps (1-4) above on the other side of the machine.

Servicing & Maintenance
Store all lubricants away from excessive heat, dust, moisture and
contaminants. Before maintenance, ensure both tractor and
attachment are stationary, with the hydraulic lift system in a neutral
position and the ignition key removed.
Wipe grease nipples with a clean cloth before greasing to avoid injecting
any dirt/grit. Press a multi-purpose lithium-based grease into each grease
nipple 3 to 5 times. Use a handheld grease gun for best results. Replace or
repair broken grease points immediately. Grease both lubrication points
on either end of the PTO shaft, and apply grease to the inner shaft.
Grease the blade rotor bearing (1). The left bearing is within the gear
reservoir and is lubricated by the same oil (see page 11 on Gear Reservoir
Oil Change).

Attaching & Resizing PTO Shaft
Before installation/maintenance, ensure both tractor and
attachment are stationary with the ignition key removed. Ensure all
safety guards are in place and cover the PTO shaft when extended,
ensure the sprung locking collar slides freely and is securely in the
groove on the PTO. Always replace worn/damaged PTO shafts.
Most PTO driven attachments are supplied with a standard size PTO shaft
which often requires resizing. Firstly, attach the rotovator to the tractor
without the PTO shaft, then raise the linkage so the PTO shaft is level/
horizontal. Measure the length between the tractor PTO and the
rotovator’s shaft. If the compressed (closed) PTO shaft length exceeds the
one measured here then the driveline will need to be cut.
