Introduction
Thank you for purchasing the Multi-Brush. This British designed and
built product has been engineered to give years of use, provided it is
used and maintained correctly.
As with all tractor mounted equipment it is essential that all operators
read and follow these instructions in order to use the Multi-Brush safely
without endangering themselves or other persons.
Machinery Markings
Your machine carries a serial number plate. Please quote your serial
number when ordering spare parts.
Application
The Multi-Brush is a unique dual-purpose brush which can be used
either with the wing brushes folded out for light brushing of large areas
such as sports fields and golf course fairways, or with all the brushes
folded together on the centre frame for more intensive brushing, for
example when brushing-in topdressing.
This equipment is designed solely for brushing sports and amenity turf.
Use in any other way is contrary to the intended use.
The manufacturer accepts no liability for damage or injury resulting from
misuse. Compliance with the instructions in this manual is essential for
safe operation.

General
This turf maintenance system is designed to be operated by a 4WD
tractor of not less than 30HP with hydraulic lifting capacity of at least
450kg. Front weights may be necessary when operating this machine.
All operators must also read and follow all instructions in the operator’s
handbook supplied with the tractor.
Before Starting the Tractor Engine
Check that the brakes are applied, drives are in neutral, guards are in
position and intact, and bystanders are clear of the machine. Do not run
the engine in a building without adequate ventilation.
Operating the Machine
Always wear suitable protective clothing (eg. Gloves and steel toecap
footwear) when operating sharp or heavy machinery.
Before moving the machine, check to ensure that all parts are in good
working order, paying particular attention to tyres, steering, brakes and
lights. Double check that the attachment is fitted securely to the tractor
3-point linkage.
Always observe the Highway Code both on and off the roads. Keep
alert and aware at all times. Remember that some people are deaf or
blind, and that children and animals can be unpredictable. Keep
travelling speeds low enough for an emergency stop to be effective and
safe at all times.
Take special care when reversing and ensure that the area behind is
clear of obstructions. Remove or avoid obstructions in the working area.

Leaving the Driving Seat
Park the tractor on level ground. Before leaving the driving seat, stop
the engine and make sure all moving parts are stationary. Apply brakes
and disengage all drives. Remove the ignition key.
Slopes
Take extra care when working on slopes.
Local undulations and sinkage will change the general slope. Avoid
ground conditions which will cause the tractor to slide or roll over. Apply
brakes before disengaging tractor gears. Keep the tractor completely
under control when disengaging the traction clutch. Remember that the
extra weight of the attachment will affect the balance and stability of your
tractor.
Inspect all components and hydraulic hoses for damage before using.
Do not use with faulty components.
Switch off tractor engine and operate spool valves to release hydraulic
pressure before connecting or disconnecting hoses. Never work on a
machine with tractor running or unreleased pressure in the hydraulic
system.
Never operate machine near bystanders.
WARNING –brushes fold out to 5.4m.
Removing the Attachment from the Tractor
Lock down all of the drop legs BEFORE uncoupling the attachment from
the 3-point linkage.
REMEMBER: IT IS THE OPERATORS RESPONSIBILITY TO ALWAYS
ENSURE THAT THIS MACHINE IS IN SAFE WORKING ORDER BE-
FORE USE AND THAT CONDITIONS ARE SUITABLE FOR IT TO BE
USED WITHOUT ENDANGERING THE OPERATOR OR OTHERS.

The following decals are affixed to your Multi-Brush which must be
obeyed at all times. Replacement decals are available free of charge
from the manufacturers.

Fitting to Tractor
The Multi-Brush is intended to be used with 4 wheel drive compact
tractors of at least 30hp. It is essential that operators follow all safety
procedures set out in the tractor operator’s manual.
The Multi-Brush simply attaches to any Category1 3-point linkage by
means of conventional top and bottom link pins. Tighten any anti-sway
chains and lock the 3 stand legs into their raised position. Ensure that
the linkage is adjusted correctly so that the Multi-Brush centre frame
hangs level from side to side. Adjust the top-link so that the centre post
to which is attaches is vertical when in operation.
Using the Multi-Brush
Connect the hydraulic pipes to the tractor (1 double-acting spool valve is
required).
For wide brushing operate the hydraulic spool valve and the 2 wing arms
will fold out. Hold the valve open until the hydraulic rams are fully
extended. Operate the valve in the other direction to fold in the brushes
for intensive brushing or transport.
WARNING: Do not operate or fold out brush without checking for
obstacles. Keep bystanders at least 5m away.
IMPORTANT! Adjusting the floatation spring
The Multi-Brush is fitted with a counterbalance spring to enable the main
centre frame of the brush to float over the ground with the same
downwards pressure as the lighter wing brushes. It is fitted as per the
following instructions.
To adjust the spring tension, all brushes should be lowered to the
ground. Then the floatation spring turnbuckle should be tightened to
increase the tension on the spring until the centre frame can be lifted by
hand with the same feeling of weight as the wing brushes.

Fit the tractor lifting arms to
the lower linkage pins of the
Multi-Brush and secure with
the lynch pins.
Fit the special top-link sup-
plied with the brush. Ensure
the upper spring anchor is at
the tractor end of the top-link.
Raise the brush to transport
height using the tractor
hydraulics.
The flotation spring assembly
can now be easily fitted to the
upper spring anchor. Ensure
the ‘D’ shackle is tightened
securely.
Ensure the brush parking stands
are raised, then lower the brush
to the ground, and adjust the
upper link to ensure the brush
headstock is vertical. Open the
wing sections and adjust the
turnbuckle to obtain the required
flotation of the main frame.
If more flotation is required, and
there is no more adjustment on the
turnbuckle. Move the spring to a
lower position.
Note: Adjustment and repositioning
of the spring must be carried out
with the linkage raised and no
tension on the spring.

Fitting the Floating Top-Link Bracket
For use on golf courses where the direction of brushing involves
traversing across severe ridge and furrow undulations, the optional
Floating Top-Link Bracket shown above should be installed. This is only
for very undulating ground to allow the brush to rock from front to back to
follow the undulations.
If the ground is flat or gently contoured this bracket should not be
installed.
If using the bracket, the counterbalance spring will need to have the
tension reduced accordingly.

Uncoupling the Multi-Brush
To uncouple the Multi-Brush from the tractor, first lift the 3-point linkage,
then fully lower and securely lock down all three drop legs. Then lower
the mainframe and uncouple from the tractor.
NEVER UNCOUPLE THE MULTI-BRUSH FROM THE TRACTOR
UNLESS ALL 3 DROP LEGS ARE SECURELY LOCKED DOWN.
After Use Maintenance
Pressure-wash all debris off the brushes each time of use, this will
considerably extend brush life. However, do not point the jet closely at
the bristles. Apply a small amount of grease to the sloping ramp on
which the hydraulic ram slides. Grease all nipples weekly.
Lock the 3 stand legs in their lower position before uncoupling the
Multi-Brush from the tractor, and always store in this position with the
brushes held clear of the ground.
