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
ATTACHING TO THE TRACTOR
SHAFT CAUSED BY INCORRECT FITTING.
