Rolliflail Series Flail Mower
This manual covers the Rolliflail group of flail mowers which are available in 1.5m, 1.8m and 2.1m cut widths.
These medium-duty machines can be front, or rear mounted by decoupling and reversing the headstock
which provides added functionality at no extra cost.
In order to cater for the front and rear mounting options, these machines can be run at 540rpm or 1000rpm.
Providing the tractor front and rear drive rotation is consistent with the machine drive rotation, the two drive
speeds can be achieved by swapping the drive pulleys over.
It is essential that the guards (including the roller) are always fitted during operation and that the machine is
operated in line with the procedures and practices detailed in this manual.
IMPORTANT
This operator’s manual should be regarded as part of the machine. Suppliers of both new and second-hand
machines are advised to retain documentary evidence that this manual was provided with the machine.
This machine is designed solely for ground vegetation control and must not be used for any other purpose.
Use in any other way is considered as contrary to the intended use. Compliance with, and strict adherence
to, the conditions of operation, service, and repair, as specified by the manufacturer, also constitute
essential elements of the intended use.
This machine should be operated, serviced, and repaired only by persons who are familiar with its
characteristics and who are acquainted with the relevant safety procedures.
Accident prevention regulations, all other generally recognised regulations on safety and occupational
medicine, and all road traffic regulations must always be observed.
Any arbitrary modifications carried out to this machine may relieve the manufacturer of liability for any
resulting damage or injury.
It is potentially hazardous to fit or use any parts other than genuine Spearhead parts.

1 Machine Description
1.1 Intended Usage
The Rolliflail group of flail mowers are ideal for matching to compact tractors and excels in parkland, amenity
mowing, golf course, orchard and paddock topping applications.
The Rolliflail group of flail mowers are designed for use on level, undulating or inclined ground. They will cut
vegetation up to 20mm thickness.
They can be mounted to agricultural tractors with a minimum of 40-50Hp and weighing at least 1500kg
dependant on the machine cutting width.

1.2 General Arrangement
The layout and naming convention used throughout this manual are shown in Figure 1.2 below
(210 model illustrated)
Figure 1.2
1.3 Rotation Definitions And Conventions
This instruction manual refers to relative rotational directions. The terms clockwise and anti-clockwise are
relative definitions and depend on the operator’s viewpoint. To eliminate confusion the following definitions will
be used throughout this text;
Under normal cutting conditions flail rotation in the flail mower will be the reverse of the tractor drive wheel
rotation.
This will be defined as ’Reverse rotation’ (RR). See Error! Reference source not found.Figure 1.3(A).
[Note: for information only; When the direction of flail rotation in the flail mower is the same as the tractor drive
wheel rotation, this is defined as ‘Forward rotation’ (FR)]
Figure 1.3
Additionally, other references to ‘clockwise’ and ‘anti-clockwise’ actions by the operator conform to international
right-hand thread conventions for ‘screw down’ and ‘un-screw’ respectively.
This convention also extends to the definition of PTO drive rotation from the prime mover; see Figure 1.3(B).

1.5 Other Model Specific Information
Although the Rolliflail group of flail mowers are rear mount as built, it is possible to turn them into front mount
machines by reversing the headstock. See Figure 1.6
Figure 1.6
IMPORTANT! Before investing time in reversing the headstock, check that the rotation direction of the tractor
front output is opposite that of the tractor rear output. (Note: Rotation direction is defined by the
Spearhead PTO rotation convention, see section 1.3). Failure to check this first, may produce no rotor
motion when changed because the gearbox overrun operates.
1.5.1 Reversing The Headstock For Front Mount Operation
Ensure that the machine is de-mounted from the tractor and standing on firm level ground within reach
of lifting equipment.
The machine is normally supplied configured for rear mount and 540rpm PTO drive, see Figure 1.8.
Before disconnecting the headstock clamps measure and record the distance from the headstock to
the drive end plate to ensure it is put in the same location when reversed.
Support the Headstock in readiness to lift the Headstock clear. Be prepared, once disconnected, the
headstock support may rotate independently of the headstock.
Figure 1.8
WARNING! Only personnel experienced in lift and hoist operation should be involved in lifting
machines.

this operation, takecare to support the rear headstock support, keeping it raised above the cowl. Do
not lower the assembly weight fully onto the box section.
Manually rotate and align the rear headstock support onto the cowl’s front slider bar.
If necessary, whilst the assembly is still supported, slide the assembly left or right to ensure that the
measurements from the cowl drive end plate to the Headstock and Tension support bracket are the
same as recorded earlier.
Re-fasten all clamp plates on the headstock and rear headstock support.
Remove the lifting aid(s)
Finally unfasten the Gearbox PTO guard and the opposing Gearbox Pinion cover, swap them over and
re-fasten them to the Gearbox.

2 Safety
2.1 Safety Warnings
The operator must read, understand and follow all of the Safety instructions. Serious injury or death may occur
unless care is taken to follow the warnings and instructions provided. The level of safety is indicated in three
levels and the following notation is used throughout this operator instruction book;
DANGER! Level 1; alerts for imminent death or critical injury.
WARNING! Level 2; warns of serious injury or possible death.
CAUTION! Level 3; indicates possible injury.
Never operate the tractor or machinery until you have read and completely understood this manual and the
tractor operator’s manual and each of the safety messages found in the manuals and those displayed on the
tractor and implement.
DANGER! It is required that all operators and personnel carrying out maintenance on this machine
familiarise themselves with the machine and this operator manual to ensure they are aware of
the dangers of incorrect use or improper or incorrect repairs.
DANGER! DO NOT attempt any maintenance of or adjustment to the machine while it is running.
Before carrying out any work on the machine follow the four safety instructions below:
1. Lower the cutting head on to the ground
2. Put thePTO out of gear
3. Apply the hand brake and if the ground is sloping, wedge the tractor securely
4. Stop the tractor engine, remove and pocket the starting key.
DANGER! Before starting, safety checks on tractor and flail mower must be carried out with regard to:
functionality, road safety and accident prevention rules.
DANGER! The condition of flails and all guards must be checked before beginning daily work –they
must be replaced if damaged or missing.
DANGER! At all times ensure that the PTO shaft guard is in position, securely fitted and in good
condition andthat thetractor PTO shaft shield is fitted.
DANGER! Keep a careful watch for passers-by who may inadvertently get in the way of cut material
being thrown from the flail mower. Flail mowers are capable under adverse conditions of
throwing objects great distances at high velocity. Stop the rotor shaft until all people are well
clear.
DANGER! Do not use the machine when there is vibration in the flail mower, as this would cause
breakage and serious damage. Find the cause of the vibration and eliminate it.
DANGER! AVOID WIRE. It can be extremely dangerous if wire catches in the rotor, and every care must
be taken to ensure this will not happen. Inspect the working area before commencing. Remove
all loose wire and obstructions and clearly mark those that are fixed so that you can avoid them.
Any unusual noise from the cutting unit area indicates that the rotor shaft may have been fouled
by an obstruction. In any such event STOP the tractor engine INSTANTLY. On no account
move the cutting unit until the rotor has completely stopped. NEVER UNDER ANY
CIRCUMSTANCES run the rotor in reverse to 'clear itself'. When the rotor has stopped, inspect
it and remove any obstruction that may be present. If working under a raised machine ensure
that it is safely supported. Before working on the rotor always stop the tractor engine and
remove the ignition key.

8999118EN: v1.1 21/12/2020
15 Original instructions (ENGLISH)
Website: www.spearheadmachinery.com
DANGER! Pay special attention when working with the machine and do not to touch fixed objects such
as road drains, walls, shafts, curbs, guard rails, tracks etc. as these could break the flails which
could cause debris to be thrown at very high speed from the machine
DANGER! Flail mowers are capable under adverse conditions of throwing objects great distances at
high velocity. CHECK the flails for wear and the attachment bolts for tightness every day during
work. A few moments; whenever the machine is stopped (e.g. whenever removing
obstructions); will help reduce flail wear or loss.
DANGER! Keep your forward speed to a level appropriate to the operating conditions. High-speed
manoeuvres are very dangerous, particularly on uneven ground where there is risk of
overturning.
DANGER! Where a flail mower is used in conjunction with tractors not fitted with a glazed safety cab, a
clear polycarbonate safety screen together with a mesh guard must be fitted to the tractor
between the operator and the cutting unit. A polycarbonate safety screen must be used on
cabs where windows are likely to be left open for ventilation purposes. It is essential that cab
windows onthe operating side; through which the cutting head is observed; are intact, clean
and closed, or a clear polycarbonate safety screen must be fitted where grass trimming
operations are carried out.
WARNING! Spearhead flail mowers have not been designed to carry towing forces. Owners or
operators that fit tow hooks to Spearhead machines with the intention of towing or hauling do so
at their own risk.
WARNING! Do not operate machinery with guards missing. Ensure that the correct guards are properly
fitted to the machine and tractor at all times and that they are in good condition. Refer to section
2.5 to ensure you have the correct guards fitted.
WARNING! While the tractor is running all personnel should keep well clear of the area around the
machine as there are numerous crushing, shearing, impact dangers caused by the machine
operation.
WARNING! Extreme careshould be taken when operating near loose objects such as gravel, rocks,
wire, and other debris. Inspect the area before mowing. Foreign objects should be removed
from the site to prevent machine damage and/or bodily injury or even death. Any objects that
cannot be removed must be clearly marked and carefully avoided by the operator. Stop mowing
immediately if flails strike a foreign object. Repair all damage and make certain the rotor shaft is
still balanced before resuming cutting operations.
WARNING! Transport the machine only at safe speeds. Serious accidents and injuries can result from
operating or transporting this equipment at unsafe speeds.
WARNING! Failure to have sufficient load over the front axle or to drive at inappropriate speeds on
undulating terrain may result in a loss of directional control.
WARNING! Check that the levers which operate the hydraulic lift are locked into position, to avoid the
machine lowering during transport.
WARNING! When driving on public roads respect other road users and obey the Highway Code.
WARNING! Never transport the machine with the rotor moving, even for short distances
WARNING! When operating the machine do not wear loose or trailing clothing which may became
snagged or entangled in moving parts.
WARNING! Never carry passengers on the tractor.
WARNING! Never carry passengers on the flail mower.

8999118EN: v1.1 21/12/2020
16 Original instructions (ENGLISH)
Website: www.spearheadmachinery.com
WARNING! Never connect the power takeoff unless the engine is stopped.
WARNING! Never approach the flail mower until the rotor has completely stopped.
WARNING! Do not enter the workingzone of the PTO shaft. It is dangerous to approach the rotating
parts of the machine
WARNING! Immediately replace any missing safety sign or any missing or damaged decal
CAUTION! Replace the PTO shaft guard or PTO coupling guard if any of the following are evident;
guard cracked or damaged, any part of the PTO shaft exposed. Ensure the PTO shaft guard is
free to rotate and the anti-rotation chains are securely fitted and effective.
CAUTION! Keep the roller in position at all times. It is an essential part of the machines guarding. The
machine must not be operated with the roller missing.
2.2 Stopping in an Emergency
In an emergency use the prime mover controls to disengage drive to the PTO.
DANGER! Be aware: Even when drive is disengaged from the PTO the rotor shaft may continue to
rotate under its own inertia for some time.
2.3 Noise
The sound level of this machine, as measured at the operator's ear, ranges from 74 dB to 75,8 dB when the cab
is closed and from 77,3 to 81,2 dB when the rear window is open. The acoustic power level is LWA 101,2. When
the sound level perceivable at the operator's ear ranges from 85 to 90 dB, the use of ear protectors is
recommended.
2.4 Personal Protective Equipment
When working in an unsealed cab or where windows and apertures are open to the environment, operators are
advised to wear suitable ear protectors, see section 2.3.
When handling cutting surfaces or hydraulic equipment, operators are advised to wear suitable gloves.
When clearing blockages, clearing wire, or working with pressurised hydraulic components, operators are
advised to wear suitable eye protection.
When working at the work site, but off the tractor unit, operators are advised to wear a ‘high-viz’ garment.
2.5 Guards
DANGER! For safe operation it is essential that that all guards and the roller must be kept in position on
the machine whenever the machine is running. Spearhead disclaim all responsibility for any
damage or injury arising as a result of guards or roller being removed, or of guards other than of
Spearhead manufacture having been fitted, or of operation of the machine other than in
accordance with these instructions.

8999118EN: v1.1 21/12/2020
17 Original instructions (ENGLISH)
Website: www.spearheadmachinery.com
WARNING! Inspect guards twice daily or immediately damage is suspected.
Always replace guards that havedamage or wear which could impair their performance. Typical damage to
inspect for is as follows;
•Drive guard and side skids - distorted or with sharp outer edges.
•PTO guards - cracked, missing portions revealing moving parts
•Flexible front guards - missing portions, damaged, or worn sufficiently to permit stones or
similar objects to be ejected beneath it in normal conditions.
2.5.1 Mandatory Guards
The General arrangement figure in section 1 and the list below show the mandatory guards required. These
along with the Danger decals and Warning decals are necessary for safe cutting operations with this flail mower;
•PTO coupling guard
•PTO shaft guard
•Drive belt guard
•Front rubber flap
•Side guard skids
•Rear rubber flap (Where fitted)
•Roller
2.6 Tractor Stability
To eliminate any risk of loss of directional control, imbalance or overturning, it is essential that the tractor is
stable during work and transport.
Before driving in transport, check that the front wheels of the tractor are both on the ground. Again, it is
advisable to have a helper to check this. Check that the tyre shows evidence of bearing load. This is especially
important to ensure forward directional control at speed on undulating terrain.
If the front tyres lift, add ballast weights to the front of the tractor. If ballast weights have been added to the
tractor, check that the plated tractor axle loads have not been exceeded.
WARNING! Failure to have sufficient load over the front axle or to drive at inappropriate speeds on
undulating terrain may result in a loss of directional control.
IMPORTANT: When transporting on the highway, it is the responsibility of the operator to obey all
relevant local highway laws.
2.7 Working On Inclined Ground
The ballast instructions in section 2.6 are sufficient for level ground operation.
Be aware that when working on inclined ground changes in the tractor centre of gravity can adversely affect the
overall stability.
There is naturally a limit to a safe amount of ballast compensation that can be applied for a given tractor unit and
a given incline. If compensating ballast is applied and the compensated axle must be driven on the public
highway to reach the work site the operator should ensure that the plated axle load is not exceeded.
Remember, a flail mower represents a significant mass which can generate a significant amount of inertia when
moved at speed. Stopping this inertia suddenly can induce overturning reactions.
DANGER! When working on inclined ground avoid high speed manoeuvres which could cause
overturning.

8999118EN: v1.1 21/12/2020
18 Original instructions (ENGLISH)
Website: www.spearheadmachinery.com
2.8 Working On Embankments
Sudden potholes at speed can quickly cause the tractor to change direction. At the same time the weight of the
implement may try to lift the front axle. This is a potentially lethal combination when working along narrow
embankments or dykes and can lead to overturning and potential drowning.
When working on top of embankments it is very important to have sufficient forward stability to ensure rapid
steerage control. Spearhead recommend 20% forward stability. This means that at least 20% of the total
vehicle weight is acting on the steering axle under normal level conditions.
DANGER! When working on raised embankments ensuresufficient weight is onthe steering wheels.
2.9 Proposition 65
Figure 2.1 –P65 Cancer And Reproductive Harm Decal

Safety decals are located on various points of the machine see
Figure 3.1. They can be identified by the yellow upper panel depicting the hazard, and the lower white panel
indicating means of avoidance or precautions to be taken. These decals have no text. It is essential that all
operators and personnel associated with the machine fully understand their meanings, which are shown in
