Introduction
The Spearhead Multi-Cut 160 and 200 are very robust high capacity Rotary Cutters
which are easy to operate and maintain To ensure trouble-free operation this manual
should be carefully studied.

requirements. Always ensure the operators are proficient with the operation of this type
of this machine.
Tractor Requirements
Tractor RequirementsTractor Requirements
Tractor Requirements
•
Spearhead strongly recommends 75hp-plus tractor with CATEGORY 2 rear
linkage.
• Ensure there is sufficient weight on front wheels of the tractor for safe transport
and stability.
• PTO must be independent live drive to enable continuous PTO drive even when
tractor clutch is pressed down.
• Before hitching, ensure position control is selected. Do not attempt to hitch in
draft control.
• Check chains and stabilizers must be in good working order to hold the
machine firmly. Do not operate without checking that chains and stabilizers are
tight.
• Spearhead particularly recommend ‘turn buckle’ type check chains
• Set linkage lift rods to an equal length.

Attaching To The Tractor
Attaching To The TractorAttaching To The Tractor
Attaching To The Tractor
Fit the machine to the tractor in the standard way, ensuring the correct match of linkage
(category 2). Check that the top link is in good order and threads are well lubricated.
Use stabilisers to take any free movement out of lower link arms.
Before fitting the machine to the tractor linkage you should ensure there is sufficient
front weight to ensure the front wheels are always in contact with the ground. This is
most important for safe transport and stability when turning on slopes.
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 to the machine, first remove bolt and tapered pin from the slip clutch
yoke and push onto splined shaft of gearbox ensuring it is fully engaged before refitting
retaining bolt/pin.
To fit the PTO, first clean and grease press pins on the yoke and simultaneously push
the PTO drive shaft onto PTO shaft of the tractor until pins engage.
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.

Setting Up & Adjustment
Setting Up & AdjustmentSetting Up & Adjustment
Setting Up & Adjustment
Height
HeightHeight
Height
Cutting height adjustment is achieved by raising or lowering the wheel. Lowering the
wheel produces a longer cut, raising the wheel leaves a shorter cut. Always set
machine level front to rear and side to side.
The wheel acts a ‘middle skid’, therefore it should be set to take equal weight to the
skids. When set properly this should prevent scalping.
Machine Protection
Machine ProtectionMachine Protection
Machine Protection
To prevent gearbox damage the PTO is fitted with a slip clutch. When cutting in
conditions where solid objects are likely to be found it is recommended that the
operator reduces the engine revs to allow the blades to pivot more easily when striking
solid objects, and proceed with caution.
The clutch settings should not be altered without reference to the Spearhead Service
Department. Never over-tighten the pressure springs on the slip clutches, this could
result in severe damage to the gearbox and drive lines, as well as infringing the
warranty. (The correct length of the spring is 29mm).
Important
ImportantImportant
Important
If the machine has been laid up for any length of time, there is a risk of the clutch plates
resting and seizing together. Never operate the machine in this condition as there will
be no protection to the drive line and gearboxes against shock loading. Refer to after
storage (page 14).

Operation
OperationOperation
Operation
Engage the PTO only when the tractor engine is at low revs to prevent shock damage
to the machine. Slowly increase the engine revs to achieve the standard 540rpm PTO
speed. If at any time serious vibration occurs, stop the engine immediately and check
that no blades are missing - following all safety precautions. The cause must be found
and rectified immediately or other components may be affected.
When in work, lower the machine to the ground carrying all its weight on the
skids/wheel, allowing the machine to follow the contours of the ground and ensuring
there is sufficient slack in the wire ropes. Select a sensible forward speed bearing in
mind the density of growth, the terrain, and the available horsepower, taking extra care
when turning, particularly on slopes.
When turning, it is not necessary to lift the machine off the ground but instead allow
sufficient room to turn in a large radius. The machine only needs to be raised when
turning in a tight corner or reversing over dense undergrowth or when operating on the
front linkage.
The machine is fitted with, as standard, 3 high lift blades complete with fin, to aid
spreading/mulching.
Transportation
TransportationTransportation
Transportation
Please observe Public Highway Regulations concerning the towing of implements, and
securely attach a registration and lighting board. Take care to slow when travelling over
rough ground and avoid bouncing machine on linkage causing unnecessary strain.

•
Never leave the tractor seat without first disengaging the PTO and stopping the
engine.
• Ensure all rotating parts have stopped turning.
• Never attempt any repairs, maintenance, service or any other checks with the
machine carried on the tractor hydraulics.
• Always fully lower to the ground, or securely prop the machine on substantial
servicing stands.
• Always replace all guards and retaining chains after servicing/maintenance is
completed.
It is imperative that the following checks are carried out in order not to invalidate your
warranty; these are carried out before the first operation, after the first hour, then
after 4 hours. These checks are:
•
Wheel nuts and tyre pressure (50psi)
• Gearbox bolts
• Blade bolts are fully tightened and in particular the castle headed nut on the
blade rotor
• Retaining bolts on the drive shaft
• Grease all points
• After the first 50 hours drain and replace the gearbox oil. Replace with EP90
Gear oil
• It is your responsibility to maintain, to ensure a long reliable working life

•Check there is no wrapping of string, plastic, grass or other debris between
rotor boss and blades.
•Inspect gearbox seals for leaks.
•Regularly check the rotor boss retaining castle nut for tightness (part
no.5771409). First remove the split pin, select the correct size socket in 3/4”
drive and fully tighten the nut.
•When replacing the split pin, do not slacken the nut to align the hole, always
tighten.
•Failure to regularly check this nut will result in serious wear to hub, which is
expensive to repair.
• It is most important that all gearbox and blade bolts are regularly checked to be
very tight. When the machine is new there will be a ‘bedding in’ period
where very frequent checking is important.

Blades
BladesBlades
Blades
Caution! When carrying out maintenance work on or near the blades be careful of
free-swinging blades over-centring and falling. It is recommended that protective
headgear, gloves and goggles are worn.
The blades can be re-sharpened by grinding the cutting edges and care must be taken
that the blades are of the same weight and length after grinding. Do not over heat
when grinding, as this will affect the hardness of the blades.
All the blades are free swinging and swivel on hardened steel bushes, which are easily
replaced. When replacing blades, it is important that blades are replaced in sets, in
order to retain balance of the rotor. Bushes must be replaced when new blades are to
be fitted.
Bushes must be replaced when new blades are to be fitted.
If the blades are showing any signs of severe wear, damage or cracking, they must be
replaced immediately. Never attempt to weld the blades; this will make them very brittle
thus extremely dangerous. Do not take risks with the cutting blades - if in doubt,
replace.
Note – The slip clutch is there to protect the drive train. If the blades strike a large
obstacle they may get damaged or break, so avoid these conditions.

When operating on abrasive soils, particularly in stubbles and similar conditions with
thin ground cover, excessive skid wear may be expected. To provide extra protection
and to prolong life of the skids, special hard facing rods are available.
If working in wet and muddy conditions, ensure that debris is not allowed to build up on
the deck.

Storage
Before storing away, thoroughly wash the machine removing all traces of grass and
dirt. Great care must be taken when washing with high-pressure hoses, do not hold
the water jet close to the paintwork. Use steam cleaners with caution, be sure to
remove all detergents to avoid any discolouring or damage to paint.
Grease all grease points until fresh grease shows. Store PTO shaft in a dry place.
After Storage
After StorageAfter Storage
After Storage
Disassemble the slip clutch and with an emery cloth remove all traces of rust on the
metal clutch plates. Check condition on the friction plates, if there is any sign of over
hearing, wear or cracking, replace with new. Do not attempt to use the machine with
damaged slip clutch plates.
Assemble the clutch and tighten the bolts to achieve a spring length of 29mm. Do not
over tighten or the clutch will not work.
Check condition of the tyre (where applicable) and then follow the maintenance
procedure covered in the servicing part of this manual. Pay particular attention to the
condition of the guards and blades.
Remember the 1000 and 2000 Swipe is designed to withstand the most rigorous
conditions and, with a little care and attention, will give many years of trouble free
service.
So as not to invalidate the warranty and to avoid problems, use only genuine parts and
make sure the machine is not driven at a speed in excess of 540rpm on the PTO.
