Before Towing/Winching
It is only possible to tow or winch the JCB MINI very slowly
for a short distance. If at all possible repair the disabled
machine where it stands.
If the machine needs to be returned to the workshop for
repair, it must be winched onto a trailer.
The machine is normally prevented from moving by
hydraulic oil locked up in the transmission circuit. The
following procedure must be carried out before attempting
to move the machine.

CAUTION
Do not attempt to tow/winch the machine without first
releasing the hydrostatic braking otherwise damage
will occur to the hydraulic pumps.
