Never attempt to operate the machine when travelling backwards, the
break back will not function, and any damage caused will not be considered
warranty. The break back feature does not excuse the machine operator of
their need to be aware of obstacles and to avoid hazards. It is your
responsibility to maintain a long reliable working life.
Manual
Recommended for
confined areas and on steep hills
The Twiga range of reach mowers have as
standard a slew ram to position the machine from
transport to work or any position midway for
narrow lane cutting. This ram also acts as the
break back ram for machine protection should an
obstacle be encountered while travelling forward.
The break back will operate if the machine is
overloaded i.e. a dense patch of vegetation, too
high a forward speed, and when working uphill.
The tractor must be halted, and the flail head
manoeuvred around the obstacle before the
break back is reset via slew control lever / switch.
Auto reset
Recommended for
normal use
This is recommended for normal use either verge
mowing or hedge cutting. When auto reset is
selected the flail head rises as the arm slews
back past an obstacle, once past, the weight of
the head causes the arm to automatically slew
forward and down to the original position.
Therefore, when verge mowing, too much weight
on rear roller will cause arm to break back
prematurely, as will too high a forward speed and
a dense crop.
Under certain conditions it may be beneficial to
turn off auto reset and operate break back
manually, especially in confined areas and up
steep hills.
