Introduction
The Spearhead Star-Cut 1210 is a heavy duty rotary mower for a set-aside, stubble
and pasture topping. By carefully following the instructions in this handbook, the
machine will give many years of trouble free operation.
Safety First
Never start using the machine until the handbook has been read and understood.
The Starcut 1210 rotary mower is a potentially lethal machine if used incorrectly and
it is essential that the operator fully understands the working before starting up.
Tractor Requirements
•Spearhead recommend tractors over 250hp.
•A clevis drawbar must be used.
•The tractor should have a minimum weight of 5000 kg.
•The tractor must have a 1000RPM PTO (20 spline x 1 ¾ ”).
•2 external hydraulic double acting services are required, for operating wing
rams with float facility.
•1 external hydraulic double acting service required for operating the height
wheels.
Attaching to the Tractor
It is essential to ensure that the tractor lift arms cannot foul the PTO shaft, even when
the tractor is turning on full lock. It is advisable to remove them altogether if there is
any doubt.
The tractor drawbar should be extended to its maximum not less then 400mm from
the PTO. This will enable turning in work without damaging the drive shaft. Never
attach the mower using the pick-up hitch as
this will cause damage to the drive shaft.
Fit the nylon washer between the mower
drawbar and the tractor clevis, as shown, to
reduce wear between the two parts. The
nylon washer is a replaceable wearing
part (4600139).
Warning
Do not attach machine
to pick up hook. This
will damage the P.T.O.

Attaching To The Tractor – Drawbar Hitch
Low Drawbar
When attached to the low drawbar
of the tractor always use the
parallel linkage bar attached to
the lower hole on the hitch plate.
High Drawbar
The parallel linkage bar must
removed and the hitch is locked
by replacing the pin in the middle
hole.
When using the high drawbar it is
not possible to use the parallel
linkage, as when the machine is
full raised the PTO shaft may be
damaged.

Attaching To The Tractor – Hydraulic Hoses
Connect the hydraulic hoses:
•Yellow & Green pair of hoses to a double acting service, to operate the height
rams to the rear axle.
•Red & Black pair hoses to a double acting service for operating the main wing
lift rams & outer wing rams with float. This is particularly important the spool
valve allows the machine to follow the ground contours.
•White & Blue pair of hoses to a double acting service for operating the middle
wings rams & rotor gearbox pivot. This double acting service must NOT have
float as the ram must be held in position.
Wing:Red & Black banded
hose, double acting spool.
Wing:White & Blue banded hose,
double acting spool c/w float
Wheel Axle:Yellow &
Green banded hose,

Spearhead Star-Cut 910/1210
Attaching To The Tractor – PTO Length
Before fitting the PTO for the first time, it may be necessary to adjust the length.
There should be maximum engagement of the sliding tubes without bottoming at the
shortest operation position. To check, first connect the mower to the tractor. Pull the
PTO shaft apart and connect to the tractor PTO output shaft and the gearbox input
shaft. Hold the half shafts next to each other in the shortest working position. If
necessary, shorten the inner and outer guard tubes equally (Fig. 1). Shorten the
inner and outer sliding profiles by the same length as the guard tubes. File all sharp
edges and remove burrs. Grease sliding profiles.
To fit the PTO, first clean and grease. Press locking pins on the yoke and
simultaneously push the PTO yoke onto PTO stub shaft of the tractor until pins
engage, check PTO input shaft is secure.
The PTO shaft is fitted with a non-rotating safety guard. It should be secured to the
machine and tractor with the two retaining chains provided.
Note:
Inspect the tractor PTO stub for damage/wear as this may affect the
attachment/removal of the Spearhead input shaft. Check also for alignment as any
concentricity will cause vibration and premature wear of the wide angle joint.

Spearhead Star-Cut 910/1210
Moving Your Machine From Transport To Work Position (UNFOLDING)
1. Ensure machine is level on firm ground, for stability.
2. Release transport strap from between the wings and reposition.
3. Operate tractor external hydraulic spool to hose marked “RED/BLACK” the
first wing rams should extend lowering the left & right hand main wing section
together onto the ground.
WARNING
The following procedure must done
in the correct order to ensure no
damage occurs and is safe.
11

Spearhead Star-Cut 910/1210
4. Operate tractor external hydraulic spool to hose marked “WHITE/BLUE” the
second/middle wing rams should extend lifting the left & right hand wing, up off
the main wing sections together. At the same time the connecting linkage
must rotate the gearbox to ensure NO DAMAGE to the drive shaft.
5. Operate tractor external hydraulic spool to hose marked “RED/BLACK” the
third set of wing rams should now extend lowering the left & right hand outer
wing section together onto the ground.
6. When all wings have been unfolded to a horizontal/work position the spool to
the first wing rams must be placed in FLOAT (RED/BLACK).
7. The spool to the second/middle wing rams must be placed in HOLD
(WHITE/BLUE), to ensure the deck & gearbox remain locked with the ram fully
extended.
8. The third/outer set of wing rams operate simultaneously with the first set of
rams controlled via the (RED/BLACK) hoses and must be allowed to float
when the machine is in work.
9. Moving from work to transport, the sequence of events MUST be reversed,
only when the machine is on firm level ground.

Setting Up Your Machine – Gearbox Turning Linkage
Checking & adjusting the rotating gearbox linkage
•Machine in work position, with all wing sections in a horizontal position.
•Ensure the middle wing hydraulic cylinders are fully extended.
•Lengthen the barrel adjusting link, until the rotor gearbox has turned fully
against the stops.
•The rotor gearbox must be turned to the correct position before engaging PTO
drive or folding the machine for transport.
Warning:
Failure to control this setting may result in damage to drive lines.
Note:
Refer to maintenance section for further information on drive shaft
alignment.
13

Spearhead Star-Cut 910/1210
Setting Up Your Machine – Level Front To Rear
When the machine is
attached to the tractor and
set at working height, the
front of the skid should be
10-
20mm higher than the
rear of the skid. This
should be measured via
the front & rear of a wing
hinge pin.
To raise the front of the mower
shorten the adjustable links that
are attached to the rear axle.
To lower the front of the mower,
lengthen the adjustable link.
+10
mm
Adjusting the link is made
much easier by placing the
machine’s weight on the
parking stands then gently
lower the machine until the
weight is off the hitch
14

Spearhead Star-Cut 910/1210
Setting Up Your Machine – Level Left To Right
Note:
If the wings are cutting lower it is better to adjust the rams down on the centre deck
‘eye bolts’.
Height of cut is controlled by varying
the amount of ram stops covering the
ram rod.
Fine adjustment and balance of cut
between the rotors is achieved by
adjusting the length of the screw
attached to the ram base.
Attention
Each ram must have
equal amount of spacers
15

Spearhead Star-Cut 910/1210
Setting Up Your Machine - Cutting Height
Cutting height can be increased or decreased by adding or reducing the amount of
spacers that are down. At all times the number of spacers covering each height ram
must be equal. Start with 4 ram spacers on all rams.
(see: Recommended Cutting Heights)
Sticker (Part No: 8770351) is mounted to the rear of the Star-Cut machine to allow
easy and quick reference to cutting heights.
16

Spearhead Star-Cut 910/1210
Operation
Once ready for work, fully raise the mower cutting height and engage the PTO with
the tractor engine at low revs to prevent shock damage to the machine. Slowly
increase the engine revs to achieve the recommended PTO speed of 1000RPM. As
indicated by the decal on top of the centre guard. If at any time serious vibration
occurs, stop the engine immediately and check the blades, following all safety
precautions. Lower the mower to the preset cutting height, select a sensible forward
speed bearing in mind the density of growth, the terrain, and the available
horsepower.
The quality of finish is determined by the forward speed, i.e. a slow speed will
produce a high quality of cut, where as faster forward speeds are used when high
output is first priority.
When in work, always ensure the hydraulic spool valve that operates the 1st main
wing rams is in float position to enable the wings to freely follow all contours of
ground (Fig. 6), and that the 2nd middle wing rams are locked with the spool in a
hold/closed position.
Fig. 6 contours of the ground
Warning
The maximum working angle the wings can safely be run
is only 7.5 degrees below horizontal when the machine is
fitted with double “Star-Cut
” blades. If the wings are
allowed to drop more than 7.5 this will result in impact
damage from the rotating blades striking the deck.
MAX
7.5
degrees
17

Spearhead Star-Cut 910/1210
Operation
Whilst operating it is possible to continue working when turning as the Star-Cut 1210
is fitted with a constant velocity joint on PTO shaft. However take care not to run the
rear tractor wheel against the mower drawbar as this will result in serious damage to
the tractor, the mower and, in particular, the PTO shaft.
The constant velocity joint on the input PTO shaft, allows the PTO to be left in gear
whilst turning out of work, e.g. on the headlands. It is important not to turn sharply
when the machine is in work as this will over-load and shorten the life of the
wide angle joint.
When operating in confined areas it is possible to cut going backwards, but it is
advisable to raise the machine, particularly if in scrub, where there is the risk of
hitting hidden solid obstacles obscured by dense undergrowth.
Always exercise particular care when operating over uneven ground surfaces. Do not
allow the blades and blade holder to frequently hit the ground.
Do not allow debris to build upon the cutting decks in dry conditions, as this can be a
fire hazard, in wet conditions it will place unnecessary strain on the machine and may
foul the drive shaft causing damage.
Warning
Do not run the machine with the wings raised,
serious damage will result to the drive lines
and gearboxes.
18

Spearhead Star-Cut 910/1210
Transportation
First disengage the PTO drive, fold the wings fully upright and secure with transport
strap. Never transport along public highways with the wings only supported by the
hydraulics.
Please observe Public Highway Regulations, concerning the towing of implements,
and securely attach a registration and lighting board.
Warning
Avoid transporting machine at high speed over rough ground.
Maximum speed on highway – 20mph (25kph).
Centre Axle
Both centre axle rams must have
all 10 spacers down covering the
ram rod.
Wing Axles
Both wing axle rams must have all
the spacers out.
Then lower the machine and keep
pressurising the rams until both
the wings rams are fully closed to
give a safe and narrow transport
