SECTION 3 TECHNICAL INFORMATION
3:1 DESCRIPTION
The Powavator 150 series is ideally suited for either primary or
secondary cultivation’s and will produce seedbeds, control
weeds, incorporate chemicals, trash and sterilising agents.
The implement has an option of Soil Blades or Spikes that are
driven from the tractor PTO. A substantial bevel gearbox with
interchangeable gear sets, enables speed change to suit soil
conditions. An overload clutch unit provides protection to the
machine.
All width versions are suitable for category 2 or 3 mounting in
the central position only. Depth of cultivation is maintained by
side mounted wheels or a rear mounted roller.

SECTION 4 SETTING INSTRUCTIONS
4:1 ATTACHING THE POWAVATOR TO THE
TRACTOR
The Powavator 150 Series is suitable for either category 2 or 3
three point linkage, it must be mounted in the central position
only. (See fig.4:1a)
Fig. 4:1a Lower Mounting Brackets
To determine the correct mounting position :-
1. With the Powavator on a firm level surface, adjust the
depth control device until the machine gearbox input shaft
is horizontal.
2. Reverse the tractor up to the machine to give 150mm
(6 ins) minimum engagement of the male half of the PTO
drive shaft in the female tube when connected to the
tractor. The safe working length between centres of the
cross journals is 660-870mm (26-34 inches).
3. Position the tractor lower link ball ends in line with the
machine lower mounting brackets.

POWAVATOR 150
4. APPLY THE TRACTOR HANDBRAKE AND SWITCH
OFF THE ENGINE
5. Insert the mounting pins through the brackets and the
tractors lower link ball ends. Secure using clip pins.
6. Adjust the tractor top link length and fit to the machine
using the mounting pin supplied. Secure using a clip pin.
7. Fit and adjust stabiliser bars or chains to limit sway to a
maximum of 50mm (2 inches).
8. Fit the PTO drive shaft to the tractor PTO, ensuring that
the end yoke quick-release pin locates fully in the tractor
PTO shaft groove. Clip the safety check chain to the
tractor.
9. Before engaging the tractor PTO, check that the length of
the PTO drive shaft is within the specified operating range
when the machine is in the horizontal and raised positions.
When raised, the angle on the universal joint must not
exceed 40º or damage may occur (see fig 4:1b).
10.Raise the parking prop and secure in the raised position.
Fig. 4:1b

POWAVATOR 150
4:2 REMOVING THE POWAVATOR FROM THE
TRACTOR
1. Locate and secure the parking prop in the lowered
position. Lower the Powavator to the ground.
2. APPLY THE TRACTOR HANDBRAKE AND SWITCH
OFF THE ENGINE.
3. Disconnect the PTO drive shaft safety guard check
chain from the tractor
4. Depress the quick-release pin on the tractor end yoke
and slide the yoke off the tractor PTO shaft and put it in
the stow position.
5. Disconnect the tractor top link from the machine.
6. Remove the stabiliser bars or chains and then
disconnect the tractor lower links from the machine.

4:4 OVERLOAD CLUTCH UNIT
The overload clutch unit (part of PTO shaft supplied) protects the
machine transmission should the blades encounter an obstruction.
CAM CLUTCH UNIT (machines prior to 2010)
The cam clutch unit is supplier-set and is not adjustable. For any
other information refer to the suppliers literature (supplied with the
machine).
FRICTION CLUTCH UNIT (machines from 2010)
If set too loosely the blades will turn erratically leading to excessive
friction plate wear and poor work finish. If set too tightly it will not
provide the necessary protection.
To adjust the clutch setting:
1. Disengage the PTO drive and switch off the tractor engine.
2. Disconnect the PTO drive shaft safety guard check chain and
remove the clutch guard from the machine.
3. Tighten two opposite nuts until the springs are coil bound as
this will help to centralise the plates.
4. Tighten the other nuts until they just touch the washers , then
tighten each nut an additional 2 1/2 complete turns for 540
rpm, or 1 3/4 turns for 1000 rpm.
5. Slacken off the two coil bound springs and reset the same as
the others.
6. Refit and secure the clutch unit safety gurad and clip the PTO
drive shaft safety guard check chain to the machine.
4:5 DEPTH CONTROL
The depth of cultivation is controlled down to a maximum
of 200mm (8 inches) by means of side mounted wheels
or a rear mounted roller.
To adjust depth :-
1. Unclip the screw adjuster handles and rotate
clockwise to increase depth or anticlockwise to
decrease depth.
2. When correct, fold the handles down and secure
using the clip.
NOTE
Adjustment should be the same on both sides to ensure
even depth of cultivation
