VERIFICATION OF WARRANTY REGISTRATION
DEALER WARRANTY INFORMATION & REGISTRATION VERIFICATION
It is imperative that the selling dealer registers this machine with Spearhead Machinery Limited before
delivery to the end user – failure to do so may affect the validity of the machine warranty.
To register machines go to the Spearhead Machinery Limited web site at
www.spearheadmachinery.com, log onto ‘Dealer Inside’ and select the ‘Machine Registration button’
which can be found in the Service Section of the site. Confirm to the customer that the machine
has been registered in the section below.
Should you experience any problems registering a machine in this manner please contact the
Spearhead Service Department on 01789 491867.
Registration Verification
NOTE TO CUSTOMER / OWNER
Please ensure that the above section has been completed and signed by the selling dealer to
verify that your machine has been registered with Spearhead Machinery Limited.
IMPORTANT: During the initial ‘bedding in’ period of a new machine it is the customer’s
responsibility to regularly inspect all nuts, bolts and hose connections for tightness and retighten if required. New hydraulic connections occasionally weep small amounts of oil as the
seals and joints settle in – where this occurs it can be cured by re-tightening the connection –
refer to torque settings chart below. The tasks stated above should be performed on an hourly
basis during the first day of work and at least daily thereafter as part of the machines general
maintenance procedure.
CAUTION: DO NOT OVER TORQUE HYDRAULIC FITTINGS AND HOSES

machine drawbar as shown. This washer is a
replaceable wearing part.
Do not attach the machine to the
pick-up hook as this will result in
serious damage to the PTO
Introduction
The Trident is a very robust high capacity flail mower that is easy to operate and
maintain, to ensure trouble-free operation this manual should be carefully studied.
Safety First
Do not start the machine until you fully understand the operation and safety
precaution requirements. Always ensure the operators are proficient with the
operation of this type of machine.
Tractor Requirements
Spearhead recommended 70 – 90HP tractor for the Trident 4000
80 – 110HP tractor for the Trident 5000
110 – 150HP tractor for the Trident 6000
Fixed clevis drawbar minimum height (17”) 430mm, at maximum extension
(14”) 355mm.
Minimum tractor weight 3000kg including ballast.
PTO must be independent live drive to enable continuous PTO drive even
when tractor clutch is pressed down.
External oil supply (min. pressure 140 bar) and free flow returns.
CAT 2 front or rear linkage.
Attaching to the Tractor – Trailed Machine
It is advisable to remove the tractor rear link arms. However, if this is not convenient,
at least check the link arms do not contact the PTO shaft when turning.
Before coupling to the tractor, it is important to check that the tractor draw bar is out
at its longest setting, which will give the tightest turning circle without risk of
bottoming the PTO shaft.
10
Spearhead Trident 4000/5000/6000
Attaching to the Tractor – Mounted Machine
It is advisable to remove the clevis drawbar from the tractor, so that it does not
contact the PTO shaft at any point.
Before coupling to the tractor, it is important to check that the tractor lift rods are set
to an equal length and that the lower link arms are set at the correct distance apart to
fit to the machine which is set at CAT 2 spacing.
Attach the lower links first, then fit the top link and finally connect the PTO and
hydraulic couplings. Care must be taken when lifting the machine for the first time
with the PTO connected otherwise the PTO shaft could bottom out and damage the
shaft, machine or tractor. (See below for Shortening of the PTO shaft).
Once connected to the tractor please ensure that the lower link arms do not slew
from side to side, by adjusting the stabilizer turn buckles on each side. This will
prevent the machine from moving from side to side when in transport, which can be
dangerous. See decal below for reference:
Shortening The Input PTO Shaft
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 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 pins on the yoke and simultaneously
push the PTO drive shaft onto the PTO shaft of the tractor until the 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.
Connect the two hydraulic pipes to the tractor’s hydraulics, thinner hose to pressure
and hose thicker to returns. It is important not to reverse the oil flow
11
Spearhead Trident 4000/5000/6000
Warning
Take care to ensure no one is beneath the raised cutting
bodies when releasing the transport strap and carrying out
the lower procedure.
Transport To Work
With Cable Operated Spool Valve
Set tractor external spool valve to supply oil to the Trident before operating the two
outer control levers to ensure the wing hydraulic rams are fully charged and extended
before removing the transport strap. Follow the same procedure for the centre lever
and rear deck.
Push all the control levers fully forward to lock into the detent position, allowing the
mowing decks to float and follow ground contours (Fig 2). Ensure the transport links
for the rear and wing bodies are safely stored.
12
Spearhead Trident 4000/5000/6000
With Hoses Only (No Valve)
Connect each hose to a different external spool on the tractor, ensuring the mower
will rise when lever is operated backwards and float when forward.
Fully charge hydraulic rams before removing the transport strap and store safely.
Note: If isolating taps are mounted on wing rams, these should be set fully
open before operating the tractor spool.
Push each control lever forward to lower the mower bodies onto the ground. Once in
work position, set the tractor controls in float, allowing the mower to follow ground
contours.
Setting Up
Height Adjustment
To achieve major adjustment of cutting height; reposition the two side plates carrying
the rear rollers. Ensure the rear roller plates are fixed parallel using the same bolt
holes in all three mower bodies. (Fig. 3).
Finer adjustment to cutting height can be achieved by lengthening or shortening the 2
threaded links onto the drawbar or top link from machine to tractor for the wings, and
the top link to the rear deck
Note: On trailed machines do not over-adjust the front tie bars placing the
drawbar at an acute angle to the tractor. This will cause premature wear
on the towing eye. Always compensate by altering the position of the
rear rollers.
13
Spearhead Trident 4000/5000/6000
Warning
Never operate the machine with other people present as it is
possible for debris to be thrown from the mower.
Warning
Never allow anyone near to the machine with the wing raised
unless it is securely propped.
Raising Wings
The Trident can be operated in work with one wing raised to overcome obstructions.
However, for prolonged use we recommend that the optional wing gearbox selector
is disengaged (Fig. 4).
14
Spearhead Trident 4000/5000/6000
Warning
Maximum recommended joint angle is 16 degrees @ 540 rpm.
Operation
Engage the PTO only when the tractor engine is at low revs to prevent shock load
damage to machine. Slowly increase the engine revs to achieve the standard 540
RPM PTO speed. If at any time serious vibration occurs, stop the engine
immediately and check that no flails 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 rear
roller, allowing the machine to follow the contours of the ground. 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.
Quality of finish is determined by the forward speed i.e. a slow speed will produce a
high quality of cut, whereas faster forward speeds are used when high output is first
priority.
When in work, always ensure the hydraulic spool valve that operates the mowing
decks is in float position to enable the decks to freely follow all contours of the
ground.
On trailed machines the constant velocity joint on the input PTO shaft can allow large
joint angles up-to 80 degrees, this should only be allowed for a brief period, for
example when turning on headlands out of work. To extend the maximum working
life of the PTO ensure the joint angle is no more than 16 degrees @ 540 rpm under
load.
Take care when turning not to run the tractor wheel against the mower drawbar or
the tractor lower links fouling the PTO, as this will result in serious damage.
Options
Scraper Wires are available for the rear rollers to prevent a build up of debris but
under difficult conditions these may clog. In normal use turning will scrub the rollers
clean.
Rear Rubber Flaps are available to prevent debris being thrown but may cause
clogging in difficult conditions.
Wheels On trailed machines we offer an option of low ground pressure wheels, ideal
for turf, or alternatively a road wheel which is ideal for road transport, especially for a
machine which is used between several sites.
15
Spearhead Trident 4000/5000/6000
First disengage the PTO drive and fully raise
the machine; fold the wings to fully upright
and attach the transport strap. Lift rear
mower to maximum and securely lock up
with adjustable transport link.
Never transport along public highways with
the wings only supported by the hydraulics;
always use the locking strap (Fig 6).
Please observe Public Highway Regulations
concerning the towing of implements and
ensure all rear lights are working.
The maximum recommended speed is
20MPH (30KM.H).

Remember, the rotor is highly complex and expensive to manufacture, please
treat with care and enjoy the benefits of the Spearhead Rotor
Never carry out any servicing or maintenance work without first disengaging the
PTO, stopping the tractor
Rotor Care
Always Operate at 540 PTO speed
Always Inspect the condition of the flails and bolts on a very regular basis
Always Replace bolts and nuts when replacing flails
Always Use genuine flail bolts and nuts. The flails and bolts are made to a
very high standard from high tensile steel, being fully heat treated and
subjected to rigorous testing in very stringent conditions to comply
with our rigid quality control requirements
Never Operate with bolts loose or flails missing.
Never Change to a different spec or type of flail, this will immediately put the
rotor out of balance.
Never Engage rotor at high PTO speeds.
Torque Settings
The torque figures given are recommended maximum settings only
18
Spearhead Trident 4000/5000/6000
Warning
Check that all gearbox fixing bolts are tight. When the machine is new there
will will be a ‘bedding in’ period when very frequent checking is important.
Warning
It is imperative the grub screws are checked on the bearing and pulley taper
locks (once bedded in, loctite glue may prove useful).
Warning
Never carry out any servicing or maintenance work without first disengaging
the PTO and stopping the tractor.
Gearboxes
Before first use check gearbox oil level, thereafter check every 8 hours.
After the first 50 hours drain and replace the gearbox oil,
thereafter, annually. Replace with EP90.
Regularly inspect gearbox seals. If oil is leaking replace immediately.
It is your responsibility to maintain a long and reliable working life.
Check that gearbox bolts are fully tightened (85 Nm Max).
Flail Rotor & Roller (Daily)
Grease all bearings daily, at least every 8 hours and especially after washing.
10-30 pumps of grease may be required to flush any contamination from the
bearings.
Check there is no wrapping of string, plastic, grass or other debris on rotor
shaft and rear roller.
Check the condition of flails and ensure all retaining bolts are tight. When
flails are replaced, care must be taken to maintain balance of the rotor shaft,
do not change to a different type.
Never operate with any flails missing. This will cause severe vibration and
lead to rapid bearing wear and quickly cause the hood to crack.
19
Spearhead Trident 4000/5000/6000
Blunt flails leave an untidy finish and absorb excessive power, when re-
sharpening always wear protective clothing and goggles.
When flails are showing severe wear, damage or cracking, they must be
replaced immediately. Never attempt to weld the flails as this will make them
very brittle, thus extremely dangerous. Do not take risks with the cutting flails,
if in doubt replace.
When replacing flails always replace bolts and nuts for new.
Regularly check that all rotor-bearing bolts are tight (85 Nm).
When replacing a worn flail with a new one, replace the diametrically opposite
flail with a new one also, to retain balance. Save the worn flail as a future
replacement opposite another worn flail.
Rear Roller
Ensure roller shafts are clamped tight
Grease rear roller daily, at least every 8 hours and especially after washing.
10-30 pumps of grease may be required until fresh grease shows.
Pulleys
Three types of pulley centers are used: Centre (6 vee pulley – 115Nm),
Gearbox (3 vee pulley – 50Nm) and Flail (2 vee pulley – 41Nm)
These must be checked and tightness maintained after the 1st hour, then
daily, thereafter weekly
The “Allen Screws” tighten the taper lock. They may require loctite to secure.
The vacant holes are to aid removal.
Regularly
Check the condition of drive belts, ensuring they are aligned and properly
tensioned to avoid any unnecessary belt wear
Remove all guards for access when tensioning belts, ensure belts are running
in line after adjustment
Check there is no wrapping of string, plastic, grass or other debris on rear
roller
Check wheel nuts for tightness (130Nm)
Tyre pressures: Turf Tyres – 26 psi max Road Tyres – 23 psi max
20
Spearhead Trident 4000/5000/6000
Primary Drive
The primary drive shaft has fitted a combined overrun and slip clutch; this should be stored in
the dry. After a long period of storage/use it may be necessary to disassemble the clutch to
check its condition.
All points should be lubricated every 8 hours of use
Secondary Drive
PTO Shaft Maintenance & Greasing
For maximum life and performance, the CV body must be greased regularly
on the primary shaft. Lubricate with the driveline in a straight position – up to
30 pumps of grease may be required
Dismantle the metal sliding tubes, clean and re-grease to operate properly
Shielding is subject to damage from abuse and weathering. Replace all

Servicing Checklist (see relevant sections for full details)
Regularly Gearbox: Inspect seals, check bolts for tightness.
Flail rotor: check bolts for tightness, check condition of flails,
check retaining bolts for tightness, check rotor bearing bolts for
tightness.
Daily Maintain correct belt tension.
Check gearbox oil level.
Grease PTO shaft.
Grease all points as shown in diagram.
Check wheel bolts and tyre pressures.
Every Year Drain and replace gearbox oil with EP90.
Inspect PTO slip clutch
Cable Controls
Care should be taken during installation and operation to ensure the cables
are not trapped or kinked
Correctly adjusted cables will position the lever with equal amount of travel in
either direction
It is recommended to pack with grease all moving parts of the spool value
detent kit, mounted on the bottom of each spool valve assembly
Storage
At the end of the season before storing, thoroughly wash the machine off, removing
all traces of grass and dirt. Great care must be taken when washing with highpressure hoses, do not hold the water jet close to the paintwork. Use steam cleaners
with caution and be sure to remove all detergents to avoid any discoloring or damage
to paint. Grease all grease points until fresh grease shows. Store PTO shaft and
drive belts in a dry place. Control levers must be kept dry. Smear grease on all
areas vulnerable to corrosion, in particular the chrome ram rods.
Remember regular maintenance will greatly increase the life of the machine
