INTRODUCTION
The Cherry-Foster GG Super Scrubber range is ideal for controlling Bracken, Rushes, Gorse
and Heather as well as creating woodland rides and forestry fire breaks. These machines can
handle heavy stone conditions.
GG1700X 66”cut 1.70m
GG2000X 78” cut 2.00m
The GG1700X is designed for use with tractors in the 60 to 100hp range, whilst the GG2000X
has a cuttingwidth of 6' 6" (2000mm), and is designed for usewith tractors in the100 to 130hp
range. Both models offer the option of a bolt on rear deflector assembly for use in heavy gorse
or light saplings in woodland to push over the material in readiness to be cut when used in
reverse.
The machine is constructed with heavy 6mm sides and top panel, substantially reinforced in
all vital areas with a pressed section superstructure to further improve strength and resistance
to stone damage, in addition to extensive box section reinforcement at the gearbox, skid and
tractor mountings. The machine also features a square rear profile to improve reverse cutting
performance, front and rear full width box section buffers fitted with heavy duty chain debris
guards to retain material for secondary cutting and tubular skids to minimise ground damage
when turning. The hinged headstock with twin suspension straps allow uneven ground
contours to be followed accurately.
Designed to be mounted in-line onto the rear 3 point linkage of a tractor, the machine is
powered by the tractor PTO, with the power transmitted through a direct drive gearbox to a
heavy duty rotor assembly with either three (1700) or four (2000) high tensile cutter chains or
blades attached. The direct drive system ensures that consistent performance in the most
arduous of conditions can be achieved without belt slippage or failure, and the system is
protected from overload with shearbolt and overun clutch protection. Please consult your
supplying dealer for details on further driveline protection including friction clutch /
gearbox options on the GG1700X.
Operating height is adjustable with the option of 3", 5" or 7" cutting heights for varying
applications. Unique tubular skids, reinforced at wearing points minimize ground or turf
damage when turning and skid height is adjusted by a simple pin system eliminating the use
of tools. All machines have in-line linkage to assist with stability when working in hilly or steep
land, and the A frame is free floating to allow the machine to follow the contours of the ground
in operation.
The high tensile chain cutters are used for all heavy conditions including woodland and scrub
growth to 1½" (38mm) diameter and are more practical than blades in stony conditions.
The high tensile blades cut grass and rushes cleanly, also bracken and heather in light stone
conditions, and require less tractor PTO horse-power than chains. Blade and Chain Cutters
can be interchanged in less than 15 minutes utilising the same rotor hub.

SAFETY NOTES
1. Never allow anyone to ride on the machine. Always keep other people away from the machine
when operating and always be aware of your surroundings/ bystanders may be deaf and/or
blind, therefore always exercise care.
2. Ensure the tractor has sufficient counter-balance weights fitted. If unsure, refer to the tractor
manual for reference.
3. Check all tyres for damage and inflation pressures.
4. Always be careful when exiting fields etc. on to public roads.
5. Check securing pins and lynch pins before using machine.
6. If any adjustments are to be carried out to the machine, always park on level ground, apply
the parking brake, stop the tractor engine, and remove the ignition key before dismounting
the tractor.
7. Check daily for loose nuts and bolts, on the cutter blade/cutter chain mounting on the rotor
assembly.
8. Always ensure that all the safety and chain debris guards are correctly fitted to the machine
before operation.
9. This machine is designed for use with tractors having a 540 rpm PTO speed with a standard 6
spline shaft. DO NOT exceed 540 rpm PTO speed.
10. Never engage the PTO or use the machine whilst in the RAISED position.
11. Never carry out any work under the raised machine without the correct safety supports in
place. NEVER RELY ONLY ON THE TRACTOR HYDRALUICS.
12. Operate only at a safe distance from bystanders and livestock and DO NOT operate along
highways or in any areas where people are present.
13. Use extra caution when operating on rough terrain and in areas where rocks and debris are
present. When used on sloping or steep ground always operate up and down the slope and
not across.

ATTACHING TO THE TRACTOR
•The GG1700X super scrubber is designed for use with tractors in the 80 to 120 HP range and
the PTO shaft is fitted with shear bolt protection and overrun clutch. The GG1700X has the
option of a friction clutch on the PTO shaft.
•The GG2000X super scrubber is deigned for the use with tractors in the 110 to 160 HP range
and the PTO shaft is fitted with a shear bolt and overrun clutch.
While it is necessary to manoeuvre the tractor to connect the machine to the 3-point linkage,
ensure that the tractor engine is switched off and the ignition key removed when fitting or
adjusting the PTO shaft.
A) Fit the Super Scrubber to the tractor 3-point linkage in the normal way, using the pins and
lynch pins provided. Always use the check chains/stay bars to limit the amount of sideways
movement. This will not only produce a better finish but will also help to prolong the life of
the machine
B) Ensure that when the machine is lifted, the top link mounting point is sufficiently clear of the
rear of the tractor cab/window. It may be necessary to limit the maximum height of the
tractor linkage.
C) Once the machine is attached to the 3-point linkage the PTO shaft should then be
connected. It may in some cases be necessary to shorten the PTO shaft to avoid the drive
shafts bottoming. If this is required, the following steps should be followed: -
i) Place the machine in its working position, flat down on level ground, apply the
parking brake, stop the tractor engine and remove the ignition key.
ii) Pull the PTO shaft apart and remove both shaft guards.
iii) Without re-assembling the shaft, fit the outer half to the machine end and the inner
half to the tractor, ensuring that both locking collars are engaged.
iv) Lay the two halved of the shaft side by side and check the overlap of the profile
tubes.
MINIMUM OVERLAP MUST NOT BE LESS THAN 350mm (14”) WITH A CLEARNCE OF
25-38mm (1” TO 1.5”) BETWEEN END OF TUBES AND YOKE WHEN THE DRIVE IS IN
ITS SHORTEST POSITON.
v) Should it be necessary to shorten the tubes, ensure that the ends are chamfered and
cleaned before re-assembly.
vi) On re-assembly the tubes should be well greased, and the guards fitted securely.
vii) On re-fitting the PTO shaft to the machine ensure that the PTO shaft securing chains
are attached on both halves of the guards to the tractor machine.
D) After fitting the PTO shaft, it will be necessary to lift the machine on the linkage to ensure
that the shaft does not foul on the front edge of the top panel of the machine. If contact can
be made, either the maximum lift height should be limited, or the top link, ensure that the
machine is still flat on the ground when lowered. If not, the maximum lift height must be
limited.
THE MANUFACTURER CANNOT BE HELD RESPONSIBLE FOR THE DAMAGE TO THE PTO
SHAFT CAUSED BY INCORRECT FITTING.

USE OF THE MACHINE
NB ANY ABUSE OF THE MACHINE WILL INVALIDATE THE WARRANTY AND COULD CREATE A SAFETY
HAZARD. USE ONLY AS RECOMMENDED IN THIS MANUAL.
A) Fit the machine to the tractor as instructed in section 2.
B) Lower the machine onto level ground; adjust the top link until the rear support straps are slack.
The machine, when operating, slide on the skids following the contours of the ground thus
maintaining an even cutting height and maximum effective guarding.
ONLY OPERATE MACHINE WITH THE SKIDS IN CONTACT WITH THE GROUND.
C) The required cutting height can be achieved by adjusting the side skids. There are 3 cutting
heights; 3”, 5” and 7”.
i) Raise the machine off the ground ensuring that it is fully supported. DO NOT RELY
ONLY ON THE TRACTOR HYDRALUICS.
ii) Before attempting any adjustment to the machine, always park on level ground, apply
the parking brake, stop the tractor engine and remove the ignition key before
dismounting the tractor.
iii) Remove skid adjuster pins, move skid to required cutting position and replace pins.
iv) Exercise caution when using blades in the lowest setting as the weight of the machine
may cause it to sink and possible grounding of the blade may result in scalping the
ground and potential blade damage.
D) Raise the machine to the transport position. DO NOT RAISE THE MACHINE OR TRAVEL TO THE
SITE TO BE CLEARED WITH THE PTO RUNNING.
E) Check the area to be worked is clear of potentially dangerous debris before commencing
cutting.
F) Check that all bystanders and livestock are well clear of the area to be cut. We recommend a
minimum of 100 metres.
G) Ensure all tractor doors and windows are closed.
H) Lower the machine to the ground. Engage PTO drive at a slow engine speed, increase engine
to give 540 rpm maximum. DO NOT ENGAGE PTO AT HIGH ENGINE REVS OR MECHANICAL
DAMAGE MAY BE CAUSED. DO NOT EXCEED 540 rpm.
I) Start cutting by moving forward at a safe working speed for the terrain and scrub to be cut.
Always start slowly to ensure that you become familiar with the operation of the machine.
Operation cutting speed is recommended as between 4 and 6 mph (subject to terrain).
J) The machine is designed to always operate with both side skids level on the ground.
K) Always reduce engine revs to tick-over before disengaging the PTO drive.
L) Always disengage the PTO before lifting the machine. DO NOT RUN THE MACHINE IN A RAISED
POSITION.
NEVER LEAVE THE TRACTOR SEAT WITH THE MACHINE RUNNING. ALWAYS PARK ON LEVEL
GROUND, APPLY THE PARKING BRAKE, STOP THE TRACTOR ENGINE AND REMOVE THE IGNITION
KEY BEFORE DISMOUTNING THE TRACTOR.

GENERAL MAINTENANCE
In order to ensure the extended durability and optimum performance of the machine, you are advised
to take careful note of the points laid out in this section.
APPLY THE PARKING BRAKE, STOP THE TRACTOR ENGINE AND REMOVE THE IGNITION KEY. NEVER
WORK UNDER A RAISED MACHINE WITHOUT THE USE OF PROPER SUPPORTS.
A) DAILY
i) CHECK gearbox oil level. The correct level is obtained by removing the plug mid way
up the back of the gearbox and filling until oil runs out of this hole. To fill with oil
remove the breather plug at the top of the gearbox. Use SAE 90 EP gear oil. Refit all
plugs. Ensure the breather plug is fitted to the top of the gearbox.
ii) Grease PTO shaft universal joints and sliding profiles.
iii) If cutter blades are fitted, they may require straightening, sharpening or replacing.
iv) Check cutter chains for damage/wear and replace where necessary.
v) Ensure that chain/blade locating bolts are tight and that the bushes are not worn.
WHEN REPLACING BUSHES OR CHAINS/BLADES, ALWAYS CHECK FOR WEAR AND DAMAGE TO THE
PIVOT BOLT AND NUT TO REPLACE IF NECESSARY. FAILURE TO DO THIS MAY RESULT IN
BLADES/CHAINS DETACHING THEMSELVES AND SERIOUS INJURY MAY RESULT.
vi) When the machine is new check tightness of all nuts and bolts after the first hour of
use and then on daily basis. Pay particular attention to the gearbox securing bolts and
the chain/blade mounting bolts.
vii) Ensure all safety guards and chain debris guards are correctly always fitted and swing
freely.
B) END OF SEASON
i) items ii to vii inclusive from daily maintenance.
ii) Empty oil from drive gearbox, clean with paraffin and fill with new SAE 90 EP oil. The
correct level is obtained by removing the plug mid-way up the back if the gearbox and
filling until oil runs out of hole. To fill with oil, remove the breather plug at the top of
the gearbox. Use SAE 90 EP oil. Refit all plugs. Ensure breather plug is fitted to top of
gearbox.
iii) Due to the corrosive nature of grass when cut, wash down the machine after use,
especially when the machine is being stored for a long period.
iv) Clear all debris wrapped around gearbox spindle and rotor disk.
v) Grease all areas where corrosion may occur.
vi) Check all chain debris guards and ensure they swing freely to produce a correct
guarding. Replace as necessary.
vii) Support the machine off the ground and store in clean, dry place.
viii) DO NOT USE A PRESSURE WASHER TO CLEAN THIS
MACHINE!
